TF series self-sealing oil suction filter outside the box

Water from the inlet into the filter,first through the coarse filter element assembly to filter out larger particles of impurities,and then to the precision filter screen to filter out small particles of impurities,clean water from the outlet discharge.In the filtration process,the impurities in the inner layer of the fine filter gradually accumulate,and a pressure difference is formed on both sides of it.When this pressure difference reaches a preset value,the automatic cleaning process begins:the sewage valve opens and the hydraulic motor chamber and hydraulic cylinder of the main assembly releases pressure and drains the water.The pressure of the hydraulic motor chamber and the sewage suction pipe drops sharply.Due to the negative pressure,the dirt on the inner wall of the fine filter screen is absorbed through the suction nozzle,which flows into the hydraulic motor chamber by the hydraulic motor and is discharged by the sewage valve,forming a sewage suction process.When the water flows through the hydraulic motor,it drives the sewage suction pipe to rotate,and the hydraulic cylinder piston drives the sewage suction pipe to do axial movement.The sewage suction component completely cleans the inner surface of the entire filter screen through the combination of axial movement and rotary movement.The whole process will last for tens of seconds.The sewage valve closes at the end of the wash,the increased water pressure causes the cylinder piston to return to its original position,and the filter begins to prepare for the next flush cycle.In the cleaning process,the normal filtration work of the filter is uninterrupted.
