It is necessary to carry out regular inspection and overhaul of the submersible mud pump which is put into use so as to understand the submersible mud pump in time so as to prevent the submerged mud pump from suddenly working and affecting the pumping of sand, Mud and other work, affect the duration, delay manpower, material and financial resources. So in daily life, diving mud pump to carry out what overhaul? The following is about diving mud pump maintenance problems introduced. Submersible mud pump maintenance problems 1, check the submersible mud pump oil chamber with or without water, if the water needs to check the reasons for troubleshooting and replace the oil; check the submersible mud pump impeller wear or cavitation, whether repair or Replacement; 2, check the submersible mud pump impeller and the seal ring between the pump body is too large to be replaced, the submersible mud pump shaft rust deformation or wear, the motor bearing wear and tear, lack of oil; 3, the motor winding insulation The layer has no signs of aging, the insulation resistance to ground is too low, the three-phase winding resistance is balanced, whether there is hall sweep signs of damage between the rotor, the junction box with water, temperature, leakage protection components are normal, submersible mud pump Of the motor inside and outside the fastening screws are loose, cooling jacket and circulating water in the presence of debris. 4, submersible mud pump removal inspection to be replaced after all 0-ring, check the control of the main contactor contact protection circuit has oxidation or burrs, diving mud pump thermal relay equipment is correct, submersible pump pump level gauge Is accurate, the float action is reliable. Pumping mouth and the surrounding deposition or clogging. Submersible mud pump pump room need to stop dredging and so on. 5, a long time do not need to dive mud pump, should be raised, cleaned to dry, upright dry and ventilated indoor storage.
