2Automatic hydraulic self-cleaning screen filters

Automatic self-cleaning process:

• Water enters into the entrance.
• First, the primary strainer filters out the larger particles of impurities, and then reaches the fine strainer.
• In the process of filtering, fine strainer gradually accumulates impurity in the water and forms a filter impurities layer. Because impurities layer accumulates inside, the two sides of the fine strainer form a pressure gauge.
• When the pressure Gage reaches the default value, self-cleaning will begin, cleaning valve opens, the hydraulic components and hydraulic cylinder motor room release pressure and discharge water; pressure in hydraulic motors room and sewage suction pipe drops sharply.
• Owing to the negative pressure, the dirt is absorbed by suction nozzle inside the fine strainer, enters into the hydraulic motor room relaying on the hydraulic motors, and then discharges from the sewage valve, thus finishes a suction sewage process.
• When the flow passes the hydraulic motors, it drives sewage suction pipe rotating, the hydraulic cylinder piston drive the sewage suction pipe for axial movement, sewage suction machine’s axial movement and rotation during the entire filter, clean the surface completely.
• The entire washing process takes several seconds, sewage valve closes after the washing. Then increased pressure drives the hydraulic cylinder piston back to its initial position, filter will prepare for the next wash cycle.
• In the washing process, the filter’s normal filtering work won’t be uninterrupted.
