Submerged pumps are generally used in tanks and work by pumping out the media through pump inlets located at the bottom of the tank and the bottom of the tank. Due to this particular mode of operation, a filter screen is typically installed at the inlet of the pump to ensure good efficiency of the pump, as well as to prevent impurities in the medium and other solid particles from entering the pump and affecting other parts of the pump. However, as the filter screen is stationary, the fine filter holes are gradually blocked with the continuous increase of the working time, so that the efficiency of the pump is continuously reduced, and when most filter holes of the filter screen are blocked, the pump can be vacuumized. At this time, the pump needs to be taken out of the tank to remove impurities on the filter screen, but the process is time-consuming and labor-consuming.
