Ott Pumps explains why it affects the normal operation of submersible pumps

1. Leakage problem: The characteristics of the submersible pump are the integral of the pump and the motor is not submerged in the water. Therefore, the leakage problem is one of the important factors affecting the normal operation of the submersible pump.

2. Stall-rotation problem: When the submersible pump stalls, the stator winding will produce a stall current of 5 to 7 times the normal full-load current. If no protection measures are taken, the submersible pump will soon be burned. There are many reasons why a submersible pump can't be blocked, such as the impeller jamming, the debris seal shaft of the mechanical seal, and dirt entanglement.

3, the power supply voltage is too low or the frequency is too low.

4, wear and corrosion: wear will greatly reduce the electric pump head, flow, performance and efficiency will be reduced, impeller and pump casing rust will cause stalling. Corrosion and corrosion of submersible pump parts will not only affect the performance of the pump, but also reduce the service life.

5. On-site problems, such as falling water level, insufficient water supply, pipeline rupture, excessive water quality, and valve blockage, will affect the normal operation of the pump.
