Although there are many reasons why the motor is burnt out, the proper use of the pump is one of the important reasons.

When using the pump, after the power is turned on, carefully observe the operation of the pump, the water should be continuous and uniform, the pump without vibration and noise before use. If suddenly shut down during operation, immediately disconnect the power and check the cause. Pump start time interval between two should be all the water pump back to the limit. If you start too early, the motor will be burned due to excessive resistance and water hammer in the water pipe. In addition, if the pump installed in the well, pay attention to the pump flow should be consistent with the normal well water, otherwise it will cause the empty machine running, burning motor.

In order to ensure the normal operation of the pump, it should be checked before use again. 1, with a multimeter to check whether the pump motor winding circuit. Insulation can be used for 500 V megohmmeter measurements, insulation resistance is less than 0.5 megohm, the pump can not be used. 2, remove the filter, rotate the pump shaft is flexible, if not flexible, should be adjusted before use. 3, gate fuse capacity selection is appropriate, do not use other wires instead of fuses. 4, turn on the power, check the impeller operation is normal (power on time not allowed more than 3 to 5 seconds, otherwise easy to burn the motor).
