What are the reasons for the failure of the submersible pump?

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 used insulation resistance megohmmeter check submersible pump, reduce insulation resistance occurred timely take maintenance measures, will not happen the motor burned out. .

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 pumps are generally in the braking state, much larger than the rated current value, the winding of submersible pump and temperature for a long time, will damage the stator winding. .
