Reason of Decreasing Insulation Resistance of Stator Winding of Motor in Deep Well Pump

Deep well pump motor stator winding insulation resistance decline reasons:
    The insulation resistance of the stator windings of the submersible motor is related to the leakage of the mechanical seal of the shaft end of the motor, the seal leakage of the motor base and the end cover, and the insulation of the motor stator winding.
    (1) damage or damage to the stator winding treatment method is to check the damage or damage to the stator winding, repair damaged or damaged winding, and re-diving motor stator windings dry, improve the stator winding insulation resistance.
    (2) oil-filled motor oil after the poor water, the oil capsule is not tightly sealed at both ends or oil bag rupture treatment method is to reload or replace the oil capsule, replace the insulating oil. If the insulation resistance of the stator winding is lower than the specified value, re-dry the stator winding.
    (3) The static sealing leakage of the joints between the frame and the end cover is to re-install or replace the seal O-ring of the joint between the base and the end cover and re-dry the stator windings of the submersible motor Processing, improve the motor stator winding insulation resistance.
    (4) motor shaft end of the mechanical seal leakage treatment method is to motor shaft extension of the mechanical seal repair or re-assembly or replacement of the new mechanical seal and re-motor stator windings dry treatment to improve the stator winding insulation resistance.
    (5) cable connector water treatment is to re-bandaged cable connector, and re-motor stator windings for drying, improve the stator winding insulation resistance.
