Submersible pump leakage is a common failure, but also endangering the safety of one of the most dangerous factors. If the submersible pump leakage, then close the knife, the transformer power distribution room in the leakage protector will trip. It should be noted that the transformer power distribution room must be configured with leakage protector, otherwise it will be very dangerous, will cause the motor burned.
Submersible pump leakage is mainly due to submersible pump pump body water, resulting in submersible pump motor winding insulation resistance decreases, resulting in protector movements. At this point with a shake table or multimeter R × 10kΩ block, measuring the motor windings have a certain leakage resistance of the shell. Submersible pump long-term use, resulting in serious wear and tear of the mechanical seal face, water infiltration, wetting the motor winding to form leakage.
Solve the problem of submersible pump leakage method is to remove the submersible pump motor on the drying room, or with 100-200W incandescent bulb drying; measure the insulation resistance infinity, and then replace the mechanical seal, Can be put into use.
Understand the phenomenon of submersible pump leakage, causes and solutions， when in the face of leakage problems can quickly determine and solve.
