1.The use of electric pump, the application of pre - European table to check motor insulation resistance, the minimum value of not less than 5 m. Inspection method is to connect a wire on the European table in the electric pump cable line, and the other connected to the motor housing, shaking table, the observation of insulation resistance value.
2.Water immersion motor should open the irrigation bolt, filled with clean water after tightening bolts, and then into the water. Oil motor oil is found to be the replacement of sealing components and then dive into the water.
3.Pump into the water or lifting, not pulling the cable to avoid cable damage or disconnect joint.
4.Electric pump into the water should be vertical, not inclined to put.
5.Sediment transport may not pump more water or mud. The water immersion motor should always clean up the sand particles in the motor cavity and replace the water in the motor chamber.
6.After pump should be cleaned of oil at the metal surface rust, and dry on the custody vertical.
Through the above six points of the specific analysis, we understand the deep well submersible pump needs to be prepared before the work, the work of the specific situation, and work needs to be done after the treatment.
