Small submersible pump use matters needing attention
Do not turn on the small submersible pump when the power supply voltage is abnormal Due to the long low-voltage power supply line in rural areas, it is a common phenomenon that the terminal voltage of the line is low. When the phase voltage is lower than 198 volts and the line voltage is lower than 342 volts, the motor speed of the submersible pump is continuously reduced. When the rated speed is lower than 70%, the start centrifugal switch is closed, causing the start winding to be heated for a long time, and even the winding and capacitor are burned out. Conversely, excessive voltage can cause a motor to overheat and burn out or the windings.
