What is the working principle of automatic recoil sewage filter? Water enters by the entrance,First, the impurities with large particles are filtered out through the coarse filter screen,Then reach the fine screen.In the process of filtering,The fine filter gradually accumulates dirt and impurities in the water,To form a filter impurity layer,Because the impurity layer is stacked on the inside of the fine filter,Therefore, a differential pressure is formed on the inside and outside sides of the fine filter screen.When the differential pressure of the filter reaches the preset value,The automatic cleaning process will begin,The supply of clean water is constantly flowing here,Open the cleaning valve,The water pressure in the cleaning room and the suction device has dropped significantly,The pressure difference between the filter cartridge and the suction pipe,Between the suction pipe and the cleaning room, a suction force is generated through the suction nozzle,Form a process of suction.At the same tim
