Cause submersible sewage pump does not move the reasons

The purchase of new submersible sewage pump or in use will inevitably encounter the submersible pump does not turn the phenomenon, and the phenomenon encountered do not know what is the reason the submersible pump does not turn the following for you to share about the causes of all kinds of submersible pumps turn not to move:
1, submersible pump does not turn there may be: sewage pump use if it is jywq with stirring function, is likely to be the delivery of liquid which contains fiber or other debris around the impeller above or blockage to the pump body inside, causing the submersible sewage pump does not turn the phenomenon.
2, submersible pump does not turn there may be the sewage pumping liquid is corrosive of ordinary cast iron is easy to corrode, corrosion after impeller nut loose, cause the impeller and the submersible pump body contact so that the submersible pump can not rotate, stainless steel submersible pump products suggested the use of stainless steel material production a.
3, submersible pump can not rotate but can also be caused by damage to the bearing of the submersible pump, the pump stuck and start the pump control cabinet will appear the phenomenon of the trip, it should be replaced with new bearings.
After 4, the replacement of the bearing or not to move the phenomenon, then why not turn the submersible pump and motor rotor of the submersible pump may be a problem, because the rotor diameter slightly rough point leads to the appearance of the submersible pump motor is difficult to rotate the phenomenon, this situation appears only to replace the motor the new rotor or the motor rotor and then to remove the old car out of 30 microns above the lathe can solve the submersible pump does not turn the phenomenon.
