What is self-cleaning filter
Pressure, through the suction nozzle to absorb the dirt inside the fine filter, from the hydraulic motor into the hydraulic motor room, discharged by the sewage valve to form a sewage absorption process.
When this differential pressure reaches the preset value, the automatic cleaning process will begin: the drain valve opens, the hydraulic unit of the main assembly and the hydraulic cylinder release the pressure and the water is discharged; the pressure in the hydraulic motor chamber and the suction pipe is greatly reduced,
Water from the inlet into the filter, first through the coarse filter components filter out the larger particles of impurities, and then reach the fine filter, through the fine filter filter fine particles of impurities, the water discharged from the outlet.
In the filtration process, the fine filter of the inner layer of impurities gradually accumulate, its inside and outside on both sides of the formation of a pressure.
