1. First of all, you should check whether the power supply of the submersible pump is powered off, the reason for the power outage, and remove the fault in time to restore the power supply.
2. The reason for the sudden failure of the submersible pump may be the tripping of the control protection switch of the submersible pump
The main reason for the tripping of the control protection switch is that the submersible pump is damaged during operation or due to the overload of the submersible pump motor. The treatment method for the sudden non-rotation of the submersible pump is to first measure the insulation resistance of the submersible pump motor, and check whether the stator winding of the submersible pump motor is damaged and whether other parts are damaged. If other parts of the submersible pump are damaged and the stator winding is damaged or the stator winding is damaged due to overload or short circuit, the damaged parts and stator winding should be repaired. If the submersible pump is not damaged and the tripping of the control protection switch is caused by the overload of the submersible pump, you should check whether the power supply voltage and the operating head of the pump are within the specified range, and adjust the power supply voltage and the operating conditions of the submersible pump to the allowable range. It can avoid overload when the submersible pump is running, and prevent the control and protection switch from tripping.
3. The broken core wire of the submersible pump power supply cable may also be the cause of the sudden failure of the submersible pump
The treatment method for the sudden non-rotation of the submersible pump is to connect the broken core wire of the motor power supply cable and wrap it with insulating tape. If the connection repaired after the power cable is broken, it needs to be immersed in water.
