The sewage pump is easy to damage? Here are some tricks to help you get it
Sewage pumps are getting more and more attention due to their wide range of uses and strong sewage capacity. However, improper use or maintenance will cause the sewage pumps to be prone to some failures. What about damage? Here are a few tips to help you get it
01 Motor rotation direction is wrong
Before using the sewage pump, make sure that the motor rotation direction is correct. Although the reverse rotation can produce water, the water output is small and the current is large. Long-term reverse rotation will cause irreversible damage to the motor windings.
02 No leakage protector installed
The leakage protector is also called a life saver. When the leakage value of the sewage sewage pump is greater than the operating current value of the leakage protector, the leakage protector will cut off the power supply of the submersible pump to ensure equipment safety and personal safety, and avoid unnecessary electrical energy waste.
03 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 submersible sewage pump will rise. When the power supply is abnormal, it will shorten the service life or even burn the submersible sewage pump.
04 Sewage sewage pump runs for a long time
Sewage sewage pump uses water as the cooling source. Long-term dehydration may cause the motor to overheat and burn.
05 Switch the machine frequently
Frequent starting of sewage pump will affect its service life. When it stops, it will produce backflow. If it is turned on immediately, the motor load will start, resulting in excessive starting current and burning of windings.
06No maintenance is usually carried out
The sewage pump will rust if it is not used continuously after it is put into the water, causing it to fail to start. When not in use for a long time, it is best not to 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, and then lift the water surface to dry and conduct a major inspection.
How to extend the service life of sewage pump
01 Replace the seal ring
After long-term use in the sewage medium, the gap between the impeller and the sealing ring may increase and need to be replaced in time.
02 Place in a ventilated and dry place
When storing during non-use period, the pump should be lifted away from the water source in time, and the water in the pump should be drained, especially in cold winter.
03 Regular inspection and replacement of accessories
Cables, motor insulation and screws shall be inspected at least once a year. If they are damaged, they shall be replaced in time.
04 Change the oil
If water is found in the oil, it should be drained, and the oil, gaskets and screw plugs should be tightened.
05 dedicated maintenance
After the operation of the submersible sewage pump fails, do not dismantle and repair it without permission, and seek professional repairs immediately.
As the submersible sewage pump works underwater, compared with other motors, the working environment is harsh. In order to ensure the "health and longevity" of the submersible sewage pump, regular inspection and maintenance are essential!
