Precautions For Submersible Pump Operation

1. The submersible pump should work at the design point. At this time, the axial force is moderate. Highest pump efficiency. The most economical and reliable.
2. The submersible pump should be fully inspected every 8 hours of operation. Whether the various instruments have changed. Whether the circuit node is hot. Whether the sound is normal. Whether the normal working current is greater than the rated value of the motor nameplate.
Note that if one of the following situations occurs, the pump should be stopped immediately.
1) The working current of the pump suddenly exceeds the rated current of the motor.
2) The water output is abnormal, and the water is intermittent. Increased sand content.
3) The insulation resistance of the motor is lower than 0.5 megohm.
4) The unit has obvious aggravated noise and vibration.
5) The grid voltage is insufficient. 5% below the rated voltage.
6) One phase of the fuse burnt out.
7) The water pipeline is damaged.
