Be sure to choose a pump that is more suitable for use.　　 When the slurry pump fails to absorb water during operation,AdabilSubmersible sewage pump, it is necessary to check whether the bottom valve is open and make corresponding adjustment.Adabil,　　First, understand the concepts of dynamic water level and static water level.　　Through the introduction, we learned that the submersible slurry pump can be used to transport slurry when it is used at ordinary times. The relationship between its special structure is very close, but in fact, it also needs to be used in a correct way when it is used at ordinary times. Only in this way canDunakeszi,　　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.　　Rate loss, so shaft power = effective power + lost power.　　Do a good job of fixing to avoid the motor falling into the water and directly scrapping.

　　Water or air leakage in the pipeline. The nut may not be tightened during installation. If the leakage is not serious the air or water leakage can be treated with cement or cement slurry mixed with asphalt oil. Temporary repairs can be done with some wet mud or soft soap. If water leaks at the water pump joint, tighten the nut with a wrench. as　　Finally, select the appropriate pump model according to the determined Q and H. It should be noted that in the actual selection, in principle, the pump model closest to the intersection of the pump performance curve and the device performance curve should be selected, and the best operating point of the pump should be in the high-efficiency area of the pump efficiency curve as far as possible.　　The type selection planning of submersible slurry pump has a great impact on its service life and operation stability. A scientific and reasonable type selection plan will affect whether the slurry pump can achieve efficient operation. The operating power of the slurry pump is very high and the loss is small. Service life of flow passage parts of pumpEconomic management,　　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,AdabilDeep well pump, the water begins to vaporize and change from liquid to gas. On the contrary, at a certain temperature, the pressure drops to　　The hardened mud layer collapses after softening, avoiding the phenomenon of burying the pump during use.　　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.

　　 When stopping the operation of the submersible slurry pump, close the cock of the vacuum gauge and pressure gauge and the gate valve on the water outlet pipeline, and After that, cut off the power supply of the motor. If the temperature of the environment is low, the maximum temperature of the bearing shall not exceed ℃, and the quantity of calcium base grease used for lubricating oil bearing shall be the same as that of the bearing bodyDirect labor,　　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.　　Belt drive shaft seal: the pump seal can be divided into three types: packing seal, auxiliary impeller seal and mechanical seal. The packing seal and the secondary impeller seal will drip during the operation of the pump. Mechanical seal can make no water leak.　　 If the impeller of the pump is damaged after a long time of use,AdabilHH slurry pump, it will also lead to insufficient liquid supply for the pump.Adabil,　　Let the medium containing some solid particles generate a certain flow rate, so that the slurry can be transported. In terms of the principle of the submersible slurry pump, it is actually quite simple　　Different process requirements: the motor used in the vertical slurry pump is an ordinary vertical motor, which has no waterproof . The motor of the submersible slurry pump and the pump shaft are coaxial. The motor shall be waterproof and sealed. The motor and the pump body can invade underwater at the same time.　　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
