How to extend the service life of sewage submersible pumps

How to extend the service life of sewage submersible pump, weihu pump after-sales department most have the right to speak, the following is the Weihu sewage submersible Pumps wholesale manufacturers after-sales department given the relevant views.
1, to determine the correct direction of rotation of the motor
   Should find out the direction of rotation of the motor, there are many types of sewage submersible pump forward and turn when the water can be, but the rotation of the water is small, the current is large, the rotation time will damage the motor winding.
2, to prevent the power supply voltage abnormal boot
3, the cable device and diving sewage pump insulation resistance requirements
   Device sewage submersible pump, the cable to overhead, the power cord should not be too long. Sewage Submersible Pumps Do not force cables when they come into the water or prevent them from cracking. Submersible pump operation do not sink into the mud, otherwise it will cause the motor heat dissipation and burn the motor winding.
4, to prevent frequent switching
   Do not frequently switch the submersible pump, this is because the pump will stop when the return, if the boot immediately, will make the motor load, resulting in the current is too large and burn the winding. Because the start when the current is very large, often launched will burn the diving sewage pump motor windings.
5, Mo to sewage submersible pump for a long time overload operation
   To prevent the sewage submersible pump for a long time overload operation, do not smoke a large amount of water and at any time to investigate the current value is not on the nameplate on the regular value, if found that the current is too large, should stop to view. Pump dehydration operation should not be too long to prevent the motor overheating and burned.
6, pay attention to normal maintenance
    Usually often see the motor, such as found under the cover with cracks, rubber seal ring damage or failure, etc., should be replaced or amended to prevent water into the submersible pump. our website:www.shwhpump.com,email:fay@welpump.com
