How do the submersible pump burn? What is the cause? The reasons for the problems and solutions are summarized as follows:
1. Grounding fault power supply. There are four core cable of the submersible pump, careful not to take the wrong power line as grounding wire.
2. Submersible pump mechanical seal damage and leakage. Often in megohm table check the submersible pump insulation resistance, insulation resistance degradation occurs to take timely measures to repair, it will not happen to burn out the motor.
3. Cable damaged water. Always check the insulation resistance of the submersible pump.
4. The impeller stuck. The impeller stuck to the fixed, than the rated current value increases, for a long time, the stator winding of submersible pump will soon burn.
5. Both ends of the stator winding shell, the breakdown of the winding.
6. Submersible pump "open", "stop" is too frequent.
7. Submersible pump running time is too long. Submersible pump dehydration operation time can only be about 1 minutes, a long time, the electric pump due to poor heat and temperature rise.
8. Lack of phase work. Lack of work, submersible pump is usually in braking state, the current than the rated value of, submersible pump winding temperature rise at this time, a long time will burn out the stator winding.
