The application of pumps involves all aspects of work and production, and some of the names are very similar, we will introduce the submersible pump and the submersible slurry pump. Is there any difference between the two　　With the continuous development of slurry pump technology, submersible slurry pump appears in response to market demand. It is especially suitable for the depth at which the vertical slurry pump cannot operate. The underwater part of the vertical slurry pump is generally not more than m, and of course it can be more than. For example, the maximum design depth of our company&#;s underwater slurry pump can reach m, but such underwater depth is not the best operating depth of this kind of pump, so it will lead to the unreliability of the operation of the vertical slurry pump from time to time.Musa River,　　 Various matching forms of long shaft deep well pump　　 The fan speed of the water pump is too low, and the air pressure and air volume are relatively small,Musa RiverAh slurry pump, so the heat cannot be dissipated.Aden ,　　The pump should be divided into two aspects: electricity and machinery. As for machinery, you can compare the previous maintenance records. The second is electricity. You should know the power of each pump motor and have a certain understanding of its control system. Slurry pump with mechanical seal　　It will generate heat, but when it is serious, it is necessary to check whether the fan of the submersible slurry pump is damaged or rotating　　There are differences.

　　Second, the power used is not matched, so the motor temperature will be too high after long-term overload operation; In addition, frequent startup during use will also lead to fever,Musa RiverBaigang deep well pump, so I　　Types of centrifugal pumps etc.　　 Prepare tools and materials: a set of metric box / open-end wrench, bearing puller (commonly known as triangle puller), magnetic dial indicator, outside micrometer, caliper, feeler gauge, copper bar, screwdriver with handle, hammer, V-shaped irons of the same specification clean kerosene, oil basin, cotton yarn etc.Product line,　　When the equipment is in use, the water delivered in the pump receives the friction with the surface of the pump impeller,Musa RiverCirculating hot water pipeline pump, so the pump needs to consume more energy to reduce the friction and resistance caused by the surface when it is rotating. Water will slowly overcome it as it flows　　Submersible slurry pump In addition, the sewage pump is usually driven by a motor, which also requires some time og quantity when switching on and off so in fact, it can be adjusted to a certain extent during use. The submersible slurry pump needs to use a line when in use　　Potential energy, pumping water up high. However, once the pump can not absorb water, the equipment is shaped like a decoration, so what is the reason for this situation? How to solve it?

　　 there is also a simple method to measure the vibration frequency of the pump by vibration method. However, when using one method, there may be some errors in the measurement results. When many equipment are used, there are other vibration sources that will affect the measurement results. Therefore, in fact, it is mainlynew product,　　What is the cause of pump overload.　　 WQ submersible sewage pump adopts a unique single or double vane impeller structure, which greatly improves the sewage passing capacity, and can effectively pass through times the diameter of the pump and solid particles with a diameter of about % of the diameter of the pump.　　 To ensure the efficient operation of the submerged slurry pump, the clearance between the impeller and the front guard plate must be adjusted regularly to keep it between (.-mm). In addition to monitoring the flow and pressure during the operation of the pump, the motor shall not exceed the rated current of the motor. Monitor oil seal and bearing at any timeMusa River,　　 Precautions for disassembly of submersible slurry pump Before disassembling the filter press, make sure that the liquid in the submersible slurry pump is completely discharged. If the rotor is disassembled, drain the lubricating oil in the rotor bearing housing. If the newly added oil is stored, it should continue to be used after maintenance. Do not dump it directly　　 strip the outer layer of the cable to expose the copper wire for to mm, gradually thin the rubber near the wire core, grind it to the oxide layer on the wire core, wipe the wire core with alcohol (or hydrochloric acid), wrap the insulation layer and sheath layer, and dry it naturally.　　 When adding lubricating oil to the pump at ordinary times, the metering must be controlled, and the excess lubricating oil in the pump must be discharged and replaced regularly.

　　The structure of the submersible slurry pump will be more intuitive. First, the equipment will use centrifugal force to drive the liquid from the impeller to the outer edge and obtain energy, and then leave the edge of the impeller at a higher speed　　 During the installation of smooth bearing components, if the installation is correct, the smooth oil is appropriate the repair is timely, and the delivery life will be long, the repair personnel should regularly repair the bearing components, check the condition of the bearings and the smooth oil, and regularly add or replace the smooth oil during the work, and the interval and writeIn Tula, otherwise the effect of the submersible slurry pump may not be obvious.Puyo,　　Only in this way can its service life be extended to a large extent.　　The packing seal,In TulaSmall deep well pump, auxiliary impeller seal and mechanical seal are mainly used. Among them, the packing seal needs small leakage and is not suitable for transporting toxic, corrosive and precious liquids; The sealing of the auxiliary impeller relies on the reverse pressure of the two sealing impellers during rotation to prevent the leakage of the medium, and can also play a role in　　The high-efficiency slurry pump has three characteristics: first, the slurry pump has high operation efficiency and low loss.

　　 Why does the demand for submersible slurry pumps increase greatly? From the perspective of market demand, although the number of submersible slurry pumps has not exceeded that of vertical slurry pumps, it has a rapid development momentum. The main reason is that the above-mentioned use is convenient and flexible; In addition, the application market of submersible slurry pump is also better than that of vertical pump　　 optimal water inflow of well m/h　　Whether the pump is evacuated or overflowed, etc., and handle it at any time.Market trend,In TulaCorrosive pipeline pump,　　There is a difference between submersible slurry pump and sewage pump. Although the media conveyed by the two are not pure water and other media, the difference between slag slurry and sewage is still large. Let&#;s take a look at the difference between the two.　　The utility and durability of the utility model, so the polymer composite materials are generally used in production.　　Submersible slurry pump Use ultrasonic method to detect whether there is cavitation in the submersible slurry pump. This method is often convenient for re detection. Even if there is some noise in the surrounding environment, it will not affect the detection results. Therefore, many pumps often have better measurement results when in use.

　　The balance ring is also disassembled; Then remove the last stage impeller and the key back and the middle section including the guide vane; in addition, remove the impellers, middle sections and guide vanes at other levels in the same way until the submerged slag slurryProduct range,　　There are many types of submersible slurry pumps available in the market, and different pump models have different performance and application fields. Therefore, although the pump has a wide range of applications, if its model is not correctly and reasonably selected, its application effect will be great　　The course can be stronger.　　 Cutting blades can be selected to cut some large block solid substances into pieces during use,In TulaSubmersible pump can pump sewage,　　The disc friction loss of the slurry pump impeller will decrease with the decrease of the impeller diameter, so that the pump efficiency of most low specific speed pumps will improve slightly after the impeller is cut. After cutting keep the blades overlapped to a certain extent, and the degree of blade overlap will decrease with the addition of specific speed　　Body. So that the pump can realize high concentration transmission without auxiliary devices. The unique sealing device can effectively balance the pressure inside and outside the oil chamber, so that the pressure at both ends of the mechanical seal can be kept balanced, which maximizes the reliable operation of the mechanical seal and greatly extends its service life　　It is located in the middle

　　The seal cannot bear the water pressure at this depth. Once the water leaks,SafiSubmersible slurry pump, the motor will not work normally, resulting in damage to the submersible slurry pump. The biggest difference between the submersible slurry pump and the horizontal slurry pump and the vertical slurry pump is that the motor of the submersible slurry pump and the shaft connected to the pump are integrated and sealed Closed.　　So it has a process of water diversion and exhaust. There are usually two ways to inject water into equipment. One is to directly inject water into the pump chamber and the other is to pump out the gas in the pump to establish a certain vacuum and introduce the water source.Safi,　　 The reasons for excessive power loss are as follows: the running speed of the screw rod is too high.　　Occurrence of personal injury accident. The slurry pump is mainly used to transport water or similar media when in use. It can also be regarded as a common pump in our life, but it will also be overloaded when in use. Let&#;s have a look todayNaivasha,　　Most of the time, we don&#;t know how to choose the pump when we buy it. In fact, we only need to choose the appropriate equipment according to our own use needs when we choose it. It&#;s more like that in a conventional family, when we use it, the flow is small　　Where ρ—— Density of transmission medium liquid (kg/m; γ—— Gravity of medium liquid (n/m; H -- pump lift (m); Q - water pump flow (m/s); G - gravitational acceleration (m/s.　　The difference between the shaft power P and the effective power PE is the power loss in the pump, which is measured by the pump efficiency. The pump efficiency is the ratio of the effective power and the shaft power, which is measured by η Indicates.　　Rotate in the rolling direction until the friction between the impeller and the front guard plate stops, then use the adjusting bolt to move the rotor backward, record the forward and backward movement gap, evenly distribute it between the front and rear guard plates of the impeller until the gap between the impeller, the front guard plate and the rear guard plate is flat, stop, and tighten the two dust discs and fasten them on the shaft. adjustment

　　The use of water pumps for agricultural drainage and irrigation can improve the ability of agriculture to resist natural disasters, increase production and ensure income, and provide material conditions for agricultural mechanization and water conservancy.　　Dynamic water level: after the pump operates normally,SafiSmall deep well pump, the water inflow in the pool and the pumping capacity of the deep well pump reach an equilibrium point, and the water level at this time is called dynamic water level.　　If the water leakage is serious, the broken pipe shall be dismantled and replaced. Lower the lift and press the nozzle of the water pump into the water for .m.Professional is king,SafiFire deep well pump, we need to know that submersible pumps generally operate in water. In fact, most of the pumps are suitable for conveying some relatively clean media, and their impellers are generally in a closed state. However, one of the media conveyed by sewage pumps may　　Potential is convenient and flexible. It is easy to operate. It can be operated by a fool who turns on the power supply under immersion; It has a wide range of applications. In many cases, because it does not need too many auxiliary facilities.　　The submersible slurry pump can be used to transport a lot of media containing solid particles when it is used at ordinary times which can be brought wherever it is needed, so it has an irreplaceable position when it is used. What is its own structure when it is used.

　　What stands out is the sealing of the container. The seal is easy to install and maintain, stable and reliable, please check,　　In order to ensure the demand for water and electricity for production and living, many units, hotels and residential areas in various provinces and cities in China have purchased it and generators. Many enterprises have also purchased generators out of their own pockets in order not to delay production. Driven by this, it and the generator naturally become popular　　It is not allowed to operate the electric pump under the condition of low lift for a long time (generally, the operating lift shall not be less than % of the rated lift), which shall be controlled within the recommended operating lift plan as far as possible to prevent the electric pump from burning out the motor due to overload. Pumps without self circulating cooling equipment prevent all of them from being exposed to the water for a long time　　 The standby submersible slurry pump shall roll the shaft / turn every week to make the bearing uniformly accept the static load and external oscillation. The building structure in the water pump room shall be reconstructed. Sound absorbing and isolating plates shall be installed around the wall and on the top of the machine room and fixed with light steel keel; The connecting holes between the machine room and other rooms are tightly blocked,Safi,　　Flexibility. The equipment has advanced structure, wide flow passage strong sewage discharge capacity, excellent material selection and strong corrosion resistance. It is suitable for conveying liquids containing solid particles, such as sandstone, cinder and tailings. So what are the requirements for its work? Let&#;s understand briefly.　　The vertical sand pump is generally a submersible slurry pump. Its main application method is that the motor and water pump can pump up the materials that need to be escorted when they are put into underwater mining.　　 If the impeller of the pump is damaged after a long time of use, it will also lead to insufficient liquid supply for the pump.

　　Be sure to choose a pump that is more suitable for use.　　The fruit is also bad; When the axial flow pump is used, its water output is relatively large, but the head is not too high,`AngaraIrrigation deep well pump, so the effect of using the submersible slurry pump in many plain areas is also relatively good; The water output and head of the mixed flow pump are actually derived from one`Angara,　　 Temperature control: an external temperature controller is used to turn on or off the pump according to the set temperature range. It is used in constant temperature, heat exchange system and other occasions requiring temperature control.　　 When adding lubricating oil to the pump at ordinary times, the metering must be controlled, and the excess lubricating oil in the pump must be discharged and replaced regularly.Ketou,　　 if the removed gasket is seriously damaged, a new gasket shall be replaced. The removed parts shall be cleaned with kerosene before assembly.　　 If the head of the submersible slurry pump is too low or the head is higher than the practical condition, the flow will be large and the current will rise. At this time, the outlet valve can be turned down to increase the resistance to control the current.　　The above is about how to replace the water seal of Boshan submersible slurry pump. In addition to the water seal, other parts of the pump also need to be replaced in time when they are damaged. Moreover, some parts of the pump are relatively easy to be damaged, so we need to replace them regularly during use　　Check whether it needs to be replaced.

　　What is the cause of pump overload.　　Suction lift refers to the distance within the suction depth at the inlet of the pump when there is water in the inlet pipeline but there is no positive pressure at the inlet (quantifier, in length). In fact, all centrifugal pumps have suction head, but the length is different. In a word, those with higher head have suction head　　The production department has to spend a lot of money to maintain and update the pump every year. The pumps made of cast iron, bronze, rubber lining, stainless steel,`AngaraPipeline pump body, chemical and water conservancy projects on the Yellow River are prone to wear,`AngaraCorrosive pipeline pump, short service life and many faultsbuild,　　 selection of pump head: generally, the pump head shall be determined by enlarging the margin of % - %.　　Balance of.　　When in use, it can drive the impeller to rotate so as to drive it to flow.

　　Head refers to the energy obtained from the pump by the unit weight of liquid output by the pump, so head refers to the effective energy obtained from the liquid output by the pump in unit time - that is, the effective power of the pump: the equation is PE= ρ GQH (W)= γ QH (W)Online consultation, which can be brought wherever it is needed it belongs to a portable workstation, because it does not need too many auxiliary facilities.　　If the flow exceeds QD, cavitation and vibration will occur, which will seriously affect the service life of the pump. Therefore, the pump head shall not be too conservative when selecting the pump. It shall be as close to the actual head of the pipeline as possible. Generally speaking, it shall not exceed times of the actual head of the pipeline.　　Generally speaking, the above two cases are the case that the slurry pump does not absorb water. The solutions are also introduced. I believe that people can deal with this problem in time. However if the problem is serious, you should find a professional`Angara,　　When the water pump is driven by electricity or diesel engine, its impeller (like an electric fan) rotates wildly, thus forming a vacuum in the impeller. In this way, the atmospheric pressure will move the water pressure to pump water. In fact, from a al point of view, it is to convert electrical or chemical energy into gravity　　Only in this way can its service life be extended to a large extent.　　 The submersible slurry pump usually relies on water cooling to dissipate heat. If the motor leaks out of the water without water cooling, the motor temperature will rise so it is easy to burn out the motor.

　　 Assembly of rotor parts of submersible slurry pump Before assembly,KulaymaWQ submersible pump parameters, apply a layer of lubricating oil on the mounting surface to protect the shaft hole from damage.　　The high-pressure water flows to the space occupied by the original bubble at a very high speed, forming an impact force. The metal surface of the pump was fatigued and damaged by these impacts. Cavitation is caused by air bubble rupture and material stamping due to the difference in air temperature and pressureKulayma,　　 transmission device type (gearbox transmission,KulaymaCentrifugal slurry pump,KulaymaSubmersible non clogging slurry pump, flat belt transmission, V-belt transmission)　　 After each use of the equipment, high-pressure water should be used to wash the pump and pipes.

Do you know the effect and form of its shaft seal? Let&#;s have a look.　　Submersible slurry pump it fills the gap in the application of slurry pump. When the submergence is deep and there is no good mud outlet, that is, the traditional slurry pump cannot be installed and operated, and the submersible slurry pump can supplement this part of the blank work point.

　　 If the head of the submersible slurry pump is too low or the head is higher than the practical condition, the flow will be large and the current will rise. At this time, the outlet valve can be turned down to increase the resistance to control the current.safety requirements , the water inflow in the pool and the pumping capacity of the deep well pump reach an equilibrium point, and the water level at this time is called dynamic water level.　　Promote the continuous expansion of the sales network group.Kulayma,　　The purpose is to avoid water leakage of the pump, but the water seal may be damaged due to faults after being used for a period of time. Let&#;s learn how to replace the water seal.　　The two have certain commonalities. They are both submersible. As the name suggests, the pump is in an invasive state when running. The submersible slurry pump is a kind of submersible pump, but generally speaking, people often say that the submersible pump refers to the clean water pump, such as the submersible pump for domestic water and farmland irrigation and pumping　　Then it can enter into the volute pump housing. Then in the volute pump casing, the medium slows down because the flow channel is also gradually expanding.

　　Second, the service life of the flow passage parts of the pump is relatively long, such as serious damage to the bearing of the pump, so that the bore will be 'swept' when the stator and rotor rub against each other, or the impeller will be stuck due to impurities such as water and grass when the pump pumps waterWell, to sum up,　　The treatment methods are as follows: Check the power supply voltage: if the voltage changes greatly, it is caused by unstable voltage, and the use should be stopped immediately to prevent more serious consequences. Or install corresponding heat dissipation protection measures to protect the motor.　　The above is the correct sequence of impeller disassembly of submersible slurry pump. Because different types of pumps have some differences in structure, we also need to refer to the instructions when disassembling.Lagdo,　　 bind the exposed copper wire to the cable core evenly heat it with an electric iron, and infiltrate tin evenly.　　Stop, then tighten the bearing seat press down the nut, and fix the axial position of the rotor. The latter submersible slurry pump uses a barrel support, which generally does not need to adjust the impeller clearance. Therefore, if there is a problem with the clearance in the future use, loosen the support clamp first, and say that the nut is loose　　 There may also be mechanical failure of the pump, such as serious damage to the bearing of the pump, so that the bore will be 'swept' when the stator and rotor rub against each other, or the impeller will be stuck due to impurities such as water and grass when the pump pumps water

　　What stands out is the sealing of the container. The seal is easy to install and maintain stable and reliable, but the price is quite expensive.Work courses,　　Wheel, mixing impeller and other main flow passage parts are made of high wear-resistant raw materials, which are wear-resistant, corrosion-resistant, non clogging, and have strong sewage discharge capacity, and can effectively pass through large solid particles. It is not limited by suction range, with high slag suction efficiency and more complete desilting. There is no need to equip auxiliary vacuum pump, and the investment is lower.　　Ah slurry pump internal structure The pump shaft is bent. After the slurry pump reverses, the reaction force of the impeller may directly top the pump shaft. If the rigidity of the pump shaft is insufficient, it will directly lead to the bending of the pump shaft, resulting in the damage of other accessories in the pump.　　 It is also possible that the fan blades of the pump are few and the air volume is insufficient, resulting in poor heat dissipation effect.Well, to sum up　　There are differences.　　When the water pump is driven by electricity or diesel engine, its impeller (like an electric fan) rotates wildly, thus forming a vacuum in the impeller. In this way, the atmospheric pressure will move the water pressure to pump water. In fact,Well, to sum upVertical multistage centrifugal pipeline pump, from a al point of view, it is to convert electrical or chemical energy into gravity　　 After each use of the equipment, high-pressure water should be used to wash the pump and pipes. The washing can be stopped until the water has no impurities.

　　 During the installation of smooth bearing components, if the installation is correct, the smooth oil is appropriate, the repair is timely,EdenSewage pump diving, and the delivery life will be long, the repair personnel should regularly repair the bearing components, check the condition of the bearings and the smooth oil, and regularly add or replace the smooth oil during the work, and the interval and write　　The effective power is also called output power, which is expressed by PE. It is the effective energy obtained in the pump by the medium liquid output from the pump in unit time.Eden, the number of impellers the lubrication method,EdenWQ submersible pump parameters, it will not affect the detection results. Therefore, many pumps tend to have better measurement results when in use.Howrah,　　Many people do not know much about the packing and sealing of equipment because of the equipment of mass and energy. Next, let&#;s learn about the packaging and sealing method of the equipment: packing sealing is very common in submersible slurry pumps. This method has good sealing performance, is easy to use, and effectively reduces the wear of the host and anti vibration kinetic energy　　The packing seal, auxiliary impeller seal and mechanical seal are mainly used. Among them, the packing seal needs small leakage and is not suitable for transporting toxic, corrosive and precious liquids; The sealing of the auxiliary impeller relies on the reverse pressure of the two sealing impellers during rotation to prevent the leakage of the medium, and can also play a role in　　Only in this way can its service life be extended to a large extent.

　　In fact, the impeller clearance of submersible slurry pump is not adjustable for all types of pump, but it is adjustable. During normal operation, the clearance needs to be adjusted regularly to keep the clearance within the range suitable for normal operation.　　And has a wide range of applications.　　What?Encyclopedic knowledge,　　So it has a process of water diversion and exhaust. There are usually two ways to inject water into equipment. One is to directly inject water into the pump chamber, which can effectively prevent high-pressure water and impurities from entering the motor cavity. In addition to the main impeller clean the part to be bound with alcohol again and wipe it dry.

　　Its main features are as follows: the whole machine is a dry-type motor pump structure. The motor is protected by mechanical seal, it is also equipped with a mixing impeller, which can pump out the slag settled at the bottom after stirring into turbulence. impellerEquipment maintenance,　　When in use, it can drive the impeller to rotate so as to drive it to flow.　　 check the cable and replace it if it is broken or broken to avoid leakage.　　Submersible slurry pump it fills the gap in the application of slurry pump. When the submergence is deep and there is no good mud outlet, that is, the traditional slurry pump cannot be installed and operated, and the submersible slurry pump can supplement this part of the blank work point.Eden,　　It is occasionally found that there is insufficient liquid supply when using, so what are the reasons for this situation and how to deal with it.　　Ensure that the service time will be extended when it is used. We all know that the submersible slurry pump needs to optimize its structure to meet the requirements of use because the medium it transports is relatively special. The structure has been optimized to　　During the process, the equipment must be regularly maintained and overhauled to avoid blockage. As the name suggests,EdenHH slurry pump, the water pump is mainly used to transport water when it is used. The effect of normal pumps is often better when it is used, but in fact, we use it at ordinary times

　　The slurry pump should be larger. In addition to the existing industrial and mining applications of the vertical slurry pump, the submersible slurry pump can also be used as a mobile slurry pump,UrumqiWear resistant slurry pump,UrumqiWQ submersible pump parameters, such as sand pumping and prospecting on board; What are the advantages of the submersible slurry pump? The advantage of the submersible slurry pump is that it is convenient and flexible, easy to operate and submerged　　 Then tighten the compression nut on the packing gland evenly to make the liquid leak out in drops, and pay attention to the temperature rise outside the packing chamber.Urumqi,　　In order to meet the use requirements of slurry pumps in different industrial fields and working conditions, we have continuously carried out research, development and improvement, so that we have different series, pump damage and disassembly.Ikire and different series of products have different performance and s. Let&#;s learn about it below　　How to disassemble the submersible slurry pump and how to assemble it after disassembly. The technical points and precautions for disassembly will be introduced to avoid disassembly,　　Do not exceed the rated current.　　After the submersible slurry pump leaves the factory, there is generally only outgoing cable,UrumqiSubmersible pump can pump sewage, and the user needs to connect it separately during installation. If the connection is wrong, so we should follow the correct steps to connect.　　 The submersible slurry pump usually relies on water cooling to dissipate heat. If the motor leaks out of the water without water cooling, the motor temperature will rise so it is easy to burn out the motor.

　　 Another possibility is that the gas is sucked in when the pump is in use.　　The discharge side of the pump must be equipped with a valve (ball valve or stop valve, etc.) and a check valve. The valve is used to regulate the operating point of the pump. The check valve can prevent the pump from reversing when the liquid flows back (the long shaft deep well pumps produced by our company are equipped with anti reversing check devices) and prevent the pump from being hit by water hammer　　Then it can enter into the volute pump housing. Then in the volute pump casing, the medium slows down because the flow channel is also gradually expanding.Service first,　　Therefore, the stator winding will be burnt out due to excessive temperature rise.　　 The submersible slurry pump usually relies on water cooling to dissipate heat. If the motor leaks out of the water without water cooling, the motor temperature will rise, so it is easy to burn out the motor.　　Generally speaking, the above two cases are the case that the slurry pump does not absorb water. The solutions are also introduced. I believe that people can deal with this problem in time. However, if the problem is serious, you must not adjust it at will. At this time, before starting again, check whether the impeller rolling is normal and whether the bearing assembly compression bolts are tightened, and then start the pump.reform,　　 the front and rear bearing glands are equipped with oil seals, which are padded with green paper or asbestos. There is a gap of .- mm between the rear gland and the bearing.　　Will it be damaged by underground humus and hot water? This is the concern of friends who want to buy stainless steel deep well pumps.　　 If the hot water within ℃ is recommended, the hot water pump must be used, and the external tap water shall be connected for cooling during operation, otherwise the motor will not be burned due to too high medium temperature.Urumqi,　　The purpose is to inject liquid higher than . MPa from the water seal ring to prevent gas leakage into the pump when the suction inlet of the submersible slurry pump is in a vacuum state. When the water pressure in the pump is higher than . MPa, the sealing fluid .-. MPa higher than the pressure in the pump can be injected to seal and reduce leakage　　 If there is abnormal sound inside the slurry pump and there is no water, it is likely that the equipment may have air infiltrating into it when absorbing water, which will cause abnormal sound inside the pump, and then at the same time, the impeller is damaged or the impeller is damaged　　Sex is different. Although the submersible slurry pump is widely used, the correct application is very important. Due to the limitation of the name of the slurry pump, some people outside the industry misunderstand this. In fact, the impurity pump dredging pump, desilting pump, etc. are all in the application scope of the slurry pump

　　There are many types of submersible slurry pumps available in the market and different pump models have different performance and application fields. Therefore, although the pump has a wide range of applications, if its model is not correctly and reasonably selected, the processes of these two pumps are also different, and the sewage pump can generally be adjusted. Submersible pumps are generally used in some special or other places.Changsha,　　 connection mode of lifting pipe (flange connection and threaded connection)　　Moreover, the leaked flammable,ChangshaTwo stage slurry pump, explosive and toxic liquid will cause fire, explosion and poisoning, and the consequences will be unimaginable.Nai sur Seine,　　 selection of raw materials for flow passage parts: the raw materials for flow passage parts of the pump can be selected according to the particle composition, particle size,ChangshaSubmersible pump can pump sewage, shape, hardness, concentration, acid, alkali and other characteristics of the transported materials.　　The submersible slurry pump is a slurry pump which is connected with the motor and works under the water at the same time. Compared with horizontal slurry pump and vertical slurry pump, the biggest advantage is that it is flexible, convenient and easy to apply to various working conditions. The most important technical point of submersible slurry pump is the tightness between its motor and pump body Stability and reliability of seals.　　 The fan speed of the water pump is too low, so the heat cannot be dissipated.

　　 The submersible slurry pump needs to be inspected after reassembly. If the pulley needs to be rotated by hand, the pump shaft should not be blocked under normal conditions. In addition, the sound of collision between the impeller and the pump shell needs to be avoided.　　In fact, as far as whether the vertical pipeline pump has a suction lift is concerned,　　 The pump body (can not) bear the pressure from the outlet pipeline system. The standby pump in the warehouse should rotate (/ times a week to make the shaft bear the load and external vibration evenly. The belt CR drive is that the motor is on the (right) side of the pump from the inlet of the pump.　　The submersible slurry pump can be used to transport a lot of media containing solid particles when it is used at ordinary times so it has an irreplaceable position when it is used. What is its own structure when it is used.　　 First remove the pump from the engine.

　　When this type of pump is used at ordinary times, the pump and motor operate in a coaxial whole. When it runs, the motor shaft will drive the impeller of the pump to rotate, and then at this time, the rotating force can be brought to the medium, so thatHow much is it,　　All kinds of newly designed mechanical seals of submersible slurry pumps contribute greatly to the growth of market share.　　In fact, as long as we understand the structure and working principle of the slurry pump, this problem is very easy to solve. We all know that the working principle of the slurry pump is to use centrifugal force to transport slurry, so we need to rotate the impeller of the slurry pump,ChangshaISG single stage vertical pipeline pump, and the connection between the impeller and the pump shaft is connected through screw threads.　　In fact, the pumps I am going to talk about here have a wide range of uses. Pumps are required for both civil and military purposes, as well as for advanced technologies, especially in the mining, chemical, metallurgical and other industrial sectors. It is a widely used general mechanical equipment. Most pumps are corroded or severely corrodedChangsha,　　Limited. According to relevant materials, the diameter of the impeller after cutting shall not be less than % of the diameter of the standard impeller, otherwise the of the pump will have a very adverse change. After the impeller of the slurry pump is cut, the flow area in the pump body increases, which makes the flow increase after the impeller is cut.　　The high-efficiency slurry pump has three characteristics: first the slurry pump has high operation efficiency and low loss.　　When the equipment is in use, the water delivered in the pump receives the friction with the surface of the pump impeller, so the pump needs to consume more energy to reduce the friction and resistance caused by the surface when it is rotating. Water will slowly overcome it as it flows

　　It should be /-/ between. When the packing is worn, the packing gland can be properly pressed. If it is worn too much, it should be replaced. The whole commissioning process of the submersible slurry pump mainly includes the above five tasks, which are mainly to pay attention to the details and the phenomena occurred during the operation, and timely deal with the problems in time to avoid being on duty Accidents during operation cause losses.　　Submersible slurry pump Use ultrasonic method to detect whether there is cavitation in the submersible slurry pump.

However, when using one method, the measurement results may have some errors. When using the submersible slurry pump,XiamenHorizontal non clogging sewage pump, there are other vibration sources that will affect the measurement results, so it is actually the main　　(b) The maximum ambient air temperature varies with seasons, it means that the pump is fullXiamen inject a small amount of water into the water compressor to divert water. When the hand pump discharges water, although the pump has a wide range of applications and different pump models have different performance and application fields. Therefore, if its model is not correctly and reasonably selected, its application effect will be great　　Different installation requirements: the vertical slurry pump needs to be fixed, while the submersible slurry pump does not need to be fixed. It can directly invade into the liquid for operation.　　 in addition, the noise method directly detects the noise of the equipment in the detection process, but such measurement will also be affected by the surrounding noise so in fact, such measurement is not very accurate.

　　Second, the power used is not matched, so the motor temperature will be too high after long-term overload operation; In addition,AkazakiQJ submersible pump, frequent startup during use will also lead to fever, so I　　The high-pressure water flows to the space occupied by the original bubble at a very high speed,AkazakiUsed pipeline pump, forming an impact force. The metal surface of the pump was fatigued and damaged by these impacts. Cavitation is caused by air bubble rupture and material stamping due to the difference in air temperature and pressureAkazaki,　　QW (WQ) submersible non blocking sewage pump needs to be equipped with a fully active water pump control cabinet under no exceptional conditions. Do not directly connect the power grid or use the knife switch to connect the power supply to ensure the normal operation of the electric pump.　　It is located in the middle, so it seems that many regions have good effects when using it.Jacmel,　　The higher the specific speed of submersible slurry pump, the smaller the allowable cutting amount of impeller diameter. In addition to the sealing effect, the auxiliary impeller of the submersible slurry pump can also reduce the axial force.　　Cavitation of the pump is caused by water evaporation of the pump. The main cause of water evaporation is related to temperature and pressure. Under a certain pressure, when the temperature rises to a certain value the water begins to vaporize and change from liquid to gas. On the contrary, at a certain temperature, the pressure drops to　　First, the reason for the motor body: the wrong connection will make the temperature rise rapidly when the equipment is used; In addition, there may be some phase to phase short circuits between stator windings, so when the situation is relatively minor, the motor is only in local places

　　The fruit is also bad; When the axial flow pump is used, its water output is relatively large, but the head is not too high, so the effect of using the submersible slurry pump in many plain areas is also relatively good; The water output and head of the mixed flow pump are actually derived from one　　Several common specifications and models.　　 Then unscrew the nut at the front end of the pump shaft, remove the cover plate,AkazakiAh slurry pump, and press out the middle impeller and water seal.investment,　　 Pipeline layout: Firmly support the water pipe and drain pipe to prevent the force of the pipe from acting on the submersible slurry pump.　　Causes: there is air or gas accumulation in the water inlet pipe of the pump, or the bottom valve is not closed tightly the water supply is not satisfied, the packing of the vacuum pump leaks seriously, and the other is to pump out the gas in the pump to establish a certain vacuum and introduce the water source.

　　When using the sand pump, be sure to pay attention to the steering divergence between the motor and the pump. The sand pump has an arrow on the pump to mark the main steering. After the power supply is connected, be careful not to exceed the bearing on the pump support to avoidInterpretation and observation,　　The water pump is not only the water supply for the city, but also the household water purifier used in our home. There is a with pump equipment to help us purify water. In any way, it can be divided into many types, each of which has different sizes, volumes and s. Therefore, many people believe that　　The working principle of the self-priming pump is to fill the pump casing with water (or there is water in the pump casing itself) before the pump is started. After startup, the impeller rotates at a high speed to make the water in the impeller channel flow to the volute. At this time, a vacuum is formed at the inlet to open the water inlet check valve. The air in the suction pipe enters the pump and　　 First remove the pump from the engine.Akazaki,　　According to the user&#;s requirements the motor can add a variety of protection devices such as water inflow detection and overheating, so that the product can operate safely for a long time under adverse working conditions.　　 the water pipe shall be short, and the cavitation allowance of the device shall be greater than that of the pump. It is recommended to use the reverse charging installation method when transporting residues with high weight concentration.　　 selection of raw materials for flow passage parts: the raw materials for flow passage parts of the pump can be selected according to the particle composition, particle size, shape, hardness, concentration, alkali and other characteristics of the transported materials.

　　If there are sundries blocked,SaseboWater well pipeline pump, the pump will not be filled with water. When this happens again, technicians need to properly adjust the liquid level in the pump sump to a proper height, it needs to be replaced in time,　　We also need to limit the starting frequency and select appropriate thermal protection devices for use.Sasebo,　　 With protection . cf fire control cabinet integrates many electrical components, which can form a three-dimensional protection for the fire pump, including voltage overvoltage and undervoltage protection, current overcurrent and undercurrent protection, overload protection, phase loss protection, overheating protection,SaseboAh slurry pump, etc. this　　 Assembly of rotor parts of submersible slurry pump Before assembly, apply a layer of lubricating oil on the mounting surface to protect the shaft hole from damage.Merton,　　The water pump can be used to transport and pressurize clean water without impurities, such as apartment, residence, villa water supply, water supply system, drinking water system and water treatment. In short, there are many uses.　　This phenomenon shows that the failure of the pump is not only a material problem, but also reminds the pump designers and producers that in addition to good working conditions, the pump should also have good corrosion resistance, high reliability and long service life. The pump shall be designed in addition to the conventional design method of fluid mechanics　　Its main features are as follows: the whole machine is a dry-type motor pump structure. The motor is protected by mechanical seal, which can effectively prevent high-pressure water and impurities from entering the motor cavity. In addition to the main impeller, it is also equipped with a mixing impeller, which can pump out the slag settled at the bottom after stirring into turbulence. impeller

　　What should be paid attention to in the process? Let&#;s learn about the precautions for using the submersible slurry pump. When the equipment is in use, the pump itself generally needs to be placed on land for use, but its suction pipe needs to be placed in water　　Eliminate hidden dangers of fire pump in time.　　The purpose is to avoid water leakage of the pump, but the water seal may be damaged due to faults after being used for a period of time. Let&#;s learn how to replace the water seal.Where can I find it?,　　 Next, it is necessary to check the water seal. If the water seal is bakelite and the wear is not too serious, you can place abrasive cloth on the glass or dry wood and then grind the water seal of Boshan submersible slurry pump flat or turn it over for use. However, if the thrust rubber water seal is used, when　　 The submersible slurry pump usually relies on water cooling to dissipate heat. If the motor leaks out of the water without water cooling the motor temperature will rise, so it is easy to burn out the motor.　　The purpose is to inject liquid higher than . MPa from the water seal ring to prevent gas leakage into the pump when the suction inlet of the submersible slurry pump is in a vacuum state. When the water pressure in the pump is higher than . MPa, the sealing fluid .-. MPa higher than the pressure in the pump can be injected to seal and reduce leakage

　　After that, before starting again check whether the impeller rolling is normal and whether the bearing assembly compression bolts are tightened, and then start the pump.Sales Department,　　 install a valve to inject water at the water inlet and outlet. This method is to install a valve on the water inlet pipe of the submersible slurry pump and connect the water pipe to inject water into the pump. This is a common and simple method.　　Required lift (m)　　The type selection design of submersible slurry pump has a great impact on the service life and operation stability of slurry pump. A scientific and reasonable model selection design will affect whether your slurry pump can achieve the best efficient operation.Sasebo,　　Body. So that the pump can realize high concentration transmission without auxiliary devices. The unique sealing device can effectively balance the pressure inside and outside the oil chamber, so that the pressure at both ends of the mechanical seal can be kept balanced, which maximizes the reliable operation of the mechanical seal and greatly extends its service life　　In fact, the impeller clearance of submersible slurry pump is not adjustable for all types of pump, but it is adjustable.
