When the submersible pump does not pump water, the motor will not be damaged if the water pump is not placed in the water. If it runs without water, the motor will burn out.
Main reason:
The electric water pump will produce thermal effect when working, which will make the motor housing hot, which will eventually affect the heating of the coil of the engine. causing the insulating part of the coil to burn, this will cause the coil to short circuit and make the motor unable to work.
Thus, engines are generally equipped with cooling devices, either by air or by water. Water pump series motors generally use water cooling to meet the cooling needs of the motor.
The above cooling device is a necessary condition for normal engine operation. Therefore, if the water pump is idling without water, theThe motor housing will continue to heat up over time and the motor will burn out. , causing the coil to short circuit and fail to operate.
