The Situation of the Submersible Pump to Stop the Pump
source:Industry News release time:2021-02-25 Article author:Rosit Popular:Air band saw
Before the submersible pump is shut down, in order to prevent the backflow of water, the valve should be closed while the power supply is cut off. The restart interval is more than 20 minutes. If one of the following situations occurs, stop the submersible pump immediately.
First, if the working current of the submersible pump exceeds the rated current of the motor suddenly, the submersible pump should be stopped immediately.
Second, if the water output is abnormal, the water is intermittently, and the sand content increases, the submersible pump must be stopped immediately.
Third, the submersible pump should be stopped immediately when the motor insulation resistance is lower than 0.5 megohm.
Fourth, when the unit has obvious noise and vibration, the submersible pump should be stopped immediately.
Fifth, the grid voltage is insufficient, and the submersible pump should be stopped immediately if it is lower than 5% of the rated voltage.
Sixth, stop the submersible pump immediately when the fuse burns out.
Finally, if the water pipeline is damaged, stop the submersible pump immediately.
