If You Don't Pay Attention To These Six Points, It Will Cause The Sewage Pump To Fail

Sewage pumps are widely used and have strong sewage discharge capabilities, so they are being paid more and more attention, but we must pay attention to these six points during use and maintenance, otherwise it will cause failure.1. The motor rotation direction is incorrect. Before use, please make sure the motor rotation direction is correct.Although reverse rotation will produce water, the water outlet is small and the flow is large. Long-term reverse rotation will cause irreversible damage to the motor windings.2. No leakage protector is installed. Leakage protector is also called a lifesaver. When the leakage value of the pump is greater than the operating current value of the leakage protector, the leakage protector will cut off the power of the submersible pump to ensure equipment safety and personal safety and avoid unnecessary waste of power.　　3. Turn on when the power supply is abnormal. The difference between the power supply voltage and the rated voltage should not exceed 10%.If the voltage is too high or too low, the temperature of the pump will rise.Turning on the power supply when the power is abnormal will shorten the service life and even burn the sewage pump.4. Long-term dehydration operation of sewage pump. This pump uses water as a cooling source. Long-term dehydration may cause the motor to overheat and combustion.5. Frequently turn on and off. Frequently start the pump will affect its service life.When stopped, a reflux will occur.If turned on immediately, the motor load will start, causing the starting current to be too high and burn the winding.6. Maintenance is usually not carried out.If the sewage pump is discontinuously placed in water, it will rust and cause it to fail to start.When not in use for a long time, do not soak in water for a long time. It should be placed in clean water and run for a few minutes to clean the mud inside and outside the pump.
