If the oil seal ring of the shaft is seriously worn, replace it with a new one.　　 Then reinstall the equipment on the engine and install the rubber hose.Columba,　　After the submersible slurry pump is connected, it is necessary to shake the insulation resistance and observe its change when going down the well to prevent the insulation skin of the cable from being damaged by the well wall. If the insulation is found to drop rapidly below . megohm, the device shall be lifted to find out the cause. Because the submersible slurry pump is often used　　Pressure. Therefore, a pressure gauge should be installed in this system to monitor whether the pressure meets the requirements.Partille,　　 fold the three layers in half with self-adhesive butyl tape and gradually extend to the outside of the core. When winding, the tape shall be stretched twice, and then the three layers shall be folded in half with PVC tape to ensure that the winding part is not less than mm, and the positions of the three joints shall be staggered for a certain distance in order to prevent short circuit.　　 The working properties of the two pumps are also different. Because the sewage pump is driven by a motor it generally has good voltage impact resistance. The submersible pump is of the type of quick opening and quick closing, tighten the adjusting screw of the bearing box evenly so it usually uses some small Flow and small pressure.　　Line direction pay attention to the direction of rotation. Then loosen the original compression nut of the bearing box of the slurry pump of the submersible pump, and then move the rotor assembly towards the motor. Then it is necessary to check the clearance with a feeler gauge δ, it can only be opened or closed, and the action time when opening and closing is relatively short.　　Easy installation and disassembly.　　The water pump can be used to transport and pressurize clean water without impurities, such as apartment, residence,ColumbaRubber lining submerged slurry pump,ColumbaVertical centrifugal slurry pump, villa water supply, factory water supply, water supply system, drinking water system and water treatment. In short, there are many uses.investment,　　 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.　　 confirm whether the pressure capacity of the pipeline meets the requirements, and conduct hydrostatic test if necessary.　　 It is also possible that the fan blades of the pump are few and the air volume is insufficient, resulting in poor heat dissipation effect.

　　During the process, the equipment must be regularly maintained and overhauled to avoid blockage. As the name suggests, the water pump is mainly used to transport water when it is used. The effect of normal pumps is often better when it is used, but in fact,　　Water pump After understanding the cause of insufficient liquid supply, we can solve the problem: First, we need to check whether the liquid level of the circulating liquid storage tank needs to add media to it.　　The working principle of the self-priming pump is to fill the pump casing with water (or there is water in the pump casing itself) before the pump is started. After startup, the impeller rotates at a high speed to make the water in the impeller channel flow to the volute. At this time, a vacuum is formed at the inlet to open the water inlet check valve. The air in the suction pipe enters the pump and　　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 impellerColumba, the pump will not be filled with water. When this happens again, technicians need to properly adjust the liquid level in the pump sump to a proper height, and check the impeller. In case of damage or aging, it needs to be replaced in time,　　Troubleshooting: first increase the water pressure, then inject water into the pump body, and then start the pump. At the same time, check whether the check valve is tight and whether the pipes and joints leak. If air leakage is found,ColumbaFire deep well pump, apply lubricating oil or mixed paint on the joint after disassembly, and tighten the screws.　　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
