　　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 stator winding will be burnt out due to excessive temperature rise.Freihannes,　　The rotation direction of QW (WQ) submersible non blocking sewage pump after connection is counterclockwise from the water inlet. Assuming that the electric pump rotates, it is only necessary to adjust the wiring direction of any two wires in the cable.　　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.Mzimba,　　What?　　A large amount of lubricating oil is stored.　　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

　　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.　　 If the deep well pump is not used continuously after running in the well, it should be started up once a week and run for - minutes to prevent the electric pump from being started due to corrosion.　　 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 open the square plug at the lower part of the pump body to remove the remaining water to avoid frost cracking. During operation, the maximum temperature of the bearing shall not exceed ℃,FreihannesFire deep well pump, and the quantity of calcium base grease used for lubricating oil bearing shall be the same as that of the bearing bodysupply,　　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.　　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.　　What?

　　 Moreover, 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.how,　　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.　　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, all centrifugal pumps have suction head, but the length is different. In a word, those with higher head have suction head　　 Next, the water seal,　　In this way, when the equipment is used again, the solvent in the pump is often less, and the power consumption is also less,FreihannesLong shaft submerged slurry pump, and the efficiency of the pump in use is often improved and the fact is　　It will generate heat, but when it is serious, it will directly burn out the insulation; There may also be some faults in the ventilation system. At this time, it is necessary to check whether the fan of the submersible slurry pump is damaged or rotating　　 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,
