Analysis on the reasons of overload of stainless steel submersible pump

Stainless steel submersible pump material both stainless steel or cast iron, motor overload are Never mind and material, so what are the reasons lead to the submersible motor overload, we analyzed the following points:
1, the power supply voltage is too low
The submersible pump is lower than in the rural areas in more rated voltage under the conditions of operation, the current in the stator windings more cause stator winding temperature rise increased and more overheating burn out.
2, pump type selection
The actual use of the load conditions and the choice of submersible pump form does not match; the choice of the submersible pump head is too high or too low.
3, mechanical failure
Stainless steel submersible pump bearing damage, the stator and rotor friction "sweeping" aquatic or water pump impeller and other debris stuck and mechanical failure will cause the submersible sewage pump stator winding.
4, manufacturers or repair of quality factors
Stainless steel submersible pump manufacturers and repair the quality of the cause of the submersible pump overload.
