1. The overload of the motor is to check whether the running current of the motor exceeds the rated current. The motor current is too large should check the current reasons, such as caused by the fault of water pump or motor should be troubleshooting; such as due to pump load caused by large, should reduce the pump load or increase of motor power, so that the power of the water pump and motor can be matched with each other, deep well pump to ensure normal and reliable operation.
2. The lack of phase operation treatment method is to check the power supply, control protection switch and the deep well pump motor wiring, etc., to identify the cause of the lack of phase, to restore the normal power supply.
3. Power supply voltage is too low to check the cause of the voltage is too low, troubleshooting, and re adjust the power supply voltage to 342V
4. Air blocking processing method is check the motor wind, breeze tract obstruction due to check, remove air duct in the accumulation of dust and grease, maintain a smooth flow of air duct. The speed of the motor recovery normal temperature rise.
5. Ambient temperature is too high treatment method is to regulate the flow and head of the pump, reduce the load of the motor or take appropriate measures to reduce the temperature, reduce the temperature of the motor.
