    How to maintain your submersible sewage pump?

    Page view

    1 determine the correct rotation direction of the motor
    It is necessary to find out the rotating direction of the motor. Nowadays, there are many types of submersible sewage pumps that can discharge water when they are rotating and rotating, but when they are rotating, the water output is small and the current is large, and the long rotating time will damage the motor winding.
    2. Prevent abnormal power on of power supply voltage
    Because the low-voltage power supply line is relatively long, the terminal voltage of the line is often too low. When the phase voltage is lower than 198 V and the line voltage is lower than 342 V, the rotation speed of the submersible sewage pump motor will be reduced. When the additional rotation speed is less than 70%, the centrifugal switch of the engine will be closed, forming that the engine coil will be electrified at all times and even burn the winding and capacitor. On the contrary, the high voltage causes the motor to overheat and burn out the winding. Therefore, in the operation of the submersible sewage pump, it is necessary for the operator to investigate the voltage value of the power supply at any time. If it is lower than 10% of the extra voltage and higher than 10% of the extra voltage, the motor shall be stopped to find out the reason and eliminate the fault.
