ShinriroVortex pump and pipeline pumpApplication scope of

　　 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.　　 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.Shinriro　　 When the electric pump is not in use, take it out of the water and do not immerse it in the water for a long time, so as to reduce the chance of the motor stator winding getting damp and increase the service life of the electric pump. When the temperature is low, the pump needs to be lifted out to prevent freezing.　　The water pump can be used to transport and pressurize clean water without impurities,ShinriroSewage pump diving, such as apartment, residence villa water supply, factory water supply, water supply system, there are many uses.Ataq,　　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 pressure　　It can improve the mechanical efficiency to a certain extent. Moreover, the molecular structure of the coating itself has good compactness, water and other media from the pump impeller during use, and also reduce the corrosion and rust as much as possible　　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

　　Submersible slurry pump In addition, it must be used continuously during transportation. If there is an interval in the middle, it must be avoided that the interval is relatively long,ShinriroHH slurry pump, so as to avoid the solidification of slurry in the pump when the operation is stopped.　　 WQ series submersible sewage pump has fixed and mobile devices, as shown in the figure. When the fixed driving device is selected, and its connecting line shall be parallel to the axis of the pump outlet) two lifting eye screws or lifting plates to lift the electric pump up and down,　　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.analysis, 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　　The whole packing body, including the packing gland, packing ring and packing, needs to be disassembled; Submersible slurry pump Disassemble the o-seal ring, shaft sleeve, balance disc and key on the shaft in turn, and then the discharge section includes the last stage guide vane　　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,ShinriroWater well pipeline pump, 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

　　Second, the service life of the flow passage parts of the pump is relatively long, saving production costs.quality standard　　The solution to the excessive temperature of the water pump: when selecting the motor, it is necessary to select one that matches its power and speed. In addition, the cooling fan should be installed on the main shaft. It is also possible to appropriately increase the number of fan blades, but pay attention to adjusting the vacuum pump　　 rotate the impeller to check whether it is flexible, and check whether the seals at the pump vent hole, water drain hole, oil drain hole and cable joint are loose. If they are loose, they must be tightened.　　 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.Shinriro,　　 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.　　The impeller of the submersible slurry pump may need to be disassembled for maintenance or repair during use. However, when we do not know the pump structure, we may make mistakes during disassembly. Let&#;s take a look at the correct disassembly of the impeller　　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
