In the mud pump, the axial force is mainly composed of the pressure difference force of the liquid effect on the impeller and the gravity of the whole rolling part. The effect direction of the two forces is the same, and the resultant force is the sum of the two forces. If the submersible slurry pump is equipped with an auxiliary impeller, the liquid effect is on the auxiliary impeller　　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.Montalvo,　　The main and feature of self-priming pump is self-priming capacity. How to improve the performance of the pump and obtain large profits requires the following points: first the discharge valve must be opened to start the self-priming pump, so that the gas can be discharged from the discharge port. Secondly, there should be enough liquid in the cavity of the self-priming pump, otherwise it will not　　When the submersible slurry pump is used at ordinary times, cavitation usually occurs which has a great impact on the impeller of the equipment itself. So how to detect whether there is cavitation when using the equipment at ordinary times?Karaj,　　We also need to limit the starting frequency and select appropriate thermal protection devices for use.　　The submersible slurry pump shall be shut down for inspection in time in case of machine problems during operation, and regular maintenance shall be done. The equipment will not be used after burning out, which will cause certain economic losses to us.　　So it is called: submersible slurry pump.

　　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.　　Whether the pump shaft is bent or rusted. In case of the above problems, loosen the packing and dredge the water channel at the same time, or remove the pump shaft for correction or replace it with a new one.　　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 gate valve or flap valve is not closed tightly.reform,　　When using the submersible slurry pump, we should do a good job in all aspects of commissioning and precautions. We also need to do a good job in protecting the equipment parts and some parts of the motor. Only in this way can we avoid the impact of water and other impurities entering the motor　　Potential energy, pumping water up high. However, once the pump can not absorb water, so what is the reason for this situation? How to solve it?　　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.

　　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.Supply chain quality management,　　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,MontalvoDeep well submersible pump, and can also play a role in　　That is, first, check whether the equipment operation noise is reasonable; second,MontalvoWQ submersible sewage pump, check whether the alarm unit has leakage and overheating alarm signals; third, check whether the vibration of the guide rod is normal; fourth, record the flow and current of the water pump operation. If there is any problem in the above inspection, the cause shall be yzed and reported in time.　　 If the pump is equipped with a vacuum gauge or pressure gauge, close the cock connected with the submersible slurry pump before starting the motor, open it after the speed is normal, and then gradually open the outlet sluice valve. If the flow is too large, if the flow is too small,　　Fourth, model selection parameters: outlet diameter, flow, dust, motor power, impeller speed, pumping rate, maximum particle and weight.　　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.　　Friction. Because if the surface of the pump is smooth when it is used, the equipment will consume less energy when it is used. Generally
