Submersible Pump Maintenance: Maintenance Step 1: 500V shake table to detect submersible pump or sewage pump insulation resistance is more than 0.25MΩ, or should be diverted submersible pump or sewage pump, the coil for drying. Maintenance Step 2: Check whether the sealing ring has aged, it should be replaced if it is aging. Repair step three: Check the bearing wear, such as rotation when there is a significant abnormal sound or blocking phenomenon, you should replace the same model with the specifications of the bearing. Maintenance Step 4: Clean the submersible pump, sewage pump housing, such as serious corrosion should be in the surface after no paint again. Maintenance step five: Check the submersible pump, sewage pump connected to the hose is solid, such as relaxation should be tightened. Tighten the submersible pump, drain all the nuts on the pump. Submersible pump maintenance precautions: submersible pump in the demolition before and after the end cover should be marked with the base seat mark. In order to repair the assembly as it is, it will not cause assembly errors caused by the shaft is not the heart; in the removal of the submersible pump impeller and bushings and other components, it should be noted that must not hard hit hard impulse, available thermal expansion principle, heating edge Tap or use "Rama" and other tools to remove. Winding burn should be analyzed for reasons (overload, pump, lack of phase, leakage leakage short circuit, etc.), remove the motor windings, do not make the silicon steel tilt shift and burr and other phenomena, so as not to knock in the new winch assembly "bell mouth "Cause ground or short circuit fault. Rewound the new coil, the enameled wire and insulating paper must be selected regular manufacturers, due to the submersible pump motor heat level is generally E, B level. Must pay attention to its level of heat corresponding. Low insulation thickness should be sufficient, and to pad inserted in place. Winding off the assembly line, be careful not to scratch the stator core coil, but also avoid using crossed repeatedly crossed.
