The structure has been optimized to　　Wheel wear is too serious; The water absorption can not reach or exceed the specified height: it may not be the problem of the pump itself, but the local water volume is too small.　　When the water level reaches, the frequency of the frequency converter drops,ShenyangVortex pump and pipeline pump,ShenyangWear resistant slurry pump, and the slurry pump operates at a low speed. The higher the water level, the lower the speed; The lower the water level, the higher the speed. At the same time, the circulation in the slag slurry pool is basically unchangedproduction costs,　　 First of all, let&#;s understand the causes of insufficient liquid supply: If the liquid level stored in the circulating liquid storage tank is lower than %, then insufficient liquid supply will occur when it is in use. Or the pump adds too much lubricating oil, which leads to accumulation　　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　　Discount. In order to meet the needs of industrial production and make the submersible pump to achieve the ideal use effect, accurate and reasonable selection is very important. In order to select the pump reasonably and correctly, the following aspects need to be considered: Selection of shaft seal form: shaft seal of submersible slurry pump

　　 Another possibility is that the gas is sucked in when the pump is in use.target,　　Therefore, the correct selection of shaft seal can ensure the safe and stable operation of slurry pump.　　Friends who are more concerned about this issue can dispel their concerns.　　If the pump outputs more medium liquid, it will certainly do more work. If it sends less water, it will certainly do less work, and the current will be correspondingly reduced. Pump power (kw) = head (m) × Flow (m/s) × The gravity of the fluid (kg/m for water) divided by (power conversion factor) divided by the efficiency of the pump (aboutShenyang,　　 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　　Under the action of auxiliary devices, it can transport the slurry, and because the sealing device itself is special it can also ensure the internal and external balance of the submersible slurry pump during transportation, so that the pressure at both ends of the equipment can be balanced during normal use　　The direction of the differential pressure force is opposite which can offset part of the axial force and prolong the service life of the bearing.

　　If there is a standby pump it is better to use two pumps in turn. If the pump is stuck, the pump can only be repaired. A net can be added at the water inlet to prevent too many impurities from entering the pump. In this way, the probability of pump sticking will be much smaller!　　 The difference between the vertical slurry pump and the submersible slurry pump The working position of the vertical slurry pump is different. The vertical slurry pump is partially immersed in the pit and cannot be completely immersed in the liquid level. The submersible slurry pump can be completely immersed (including the motor part) below the liquid level; Use of motor for vertical slurry pumpAomori,　　; When the electric pump has sudden noise or large vibration; When the protection switch frequency trips.　　Then there are new structures, such as thermohydrodynamic seals, backup seals and asymmetric molded metal single wall bellows seals.Hamburg-Wandsbek,　　 A trash trap can be added at the position of the water inlet pipe and used at an angle of degrees, and then a filter screen is installed in the trap to filter impurities for the second time, so as to avoid the blockage of the submersible slurry pump during use.　　There are differences.　　 Selection of pipeline diameter: the selection of pipeline shall consider the one-time purchase cost, long-term operation cost and operation reliability.
