Check the submerged mud pump oil room with or without water, if the water needs to check the reasons to troubleshoot and replace the oil; check the submersible mud pump impeller wear or cavitation, whether repair or replacement; check the submersible pump impeller And the seal ring between the pump body is too large to be replaced, whether the shaft of the submersible mud pump rust deformation or wear, motor bearings wear and tear; lack of signs of aging of the motor winding insulation, to the insulation resistance is too Low, three-phase winding resistance is balanced, whether there is hall sweep signs of damage between the rotor, the junction box with or without water, temperature, leakage protection components are normal, submersible mud pump motor internal and external fastening screws with or without release, cooling Set and circulating water pipes in the debris. Submersible mud pump removal inspection need to replace all 0-ring, check the protection of the main contactor circuit contactor oxidation or glitches, submersible mud pump thermal relay equipment is correct, the submersible mud pump pump level gauge is accurate , The ball movement is reliable. Pumping mouth and the surrounding deposition or clogging. Submersible mud pump pump room need to stop dredging and so on. For a long time do not have the submersible mud pump, should be raised, clean dry, upright dry and ventilated indoor storage.
　　
Only regular inspection and overhaul of the submersible mud pump can better understand the submersible mud pump and avoid the sudden failure of the submersible mud pump to work, which will affect the work of pumping sand, pumping ore powder and pumping mud, etc., affecting the construction period, reducing the manpower and material resources And financial resources. Therefore, we can see the importance of regularly servicing and maintaining the submersible slurry pump.
