Automatic backwash filter overcomes the domestic other device ( The common filter) Filter easy to jam, often use process need to change or wash the shortcomings. The device can use own hydraulic oil system, institutions that drive make it automatically and continuously impact off screen solid contaminants, maintain a constant flow area filter, stable oil system, reduce the pollution of oil; The device working process does not affect the internal system pressure, flow and temperature; High precision filter; Big oil capacity, low pressure loss; Installed to the system without personnel operation, less maintenance workload; Shortage of lubricating oil in fault caused by plant itself.

automatic backwash filter principle

1, filtering the normal work, water diversion Industrial Valves to open. Need to deal with the water through the filter using the principle of inertia and the tiny particles in the water impurity and suspended matter due to inertia effect deposition near the outlet. 2, normal wash, wash blowdown flow diversion Industrial Valves is open. When screen intercept the tiny particles in the water impurity and suspended matter reaches a certain amount, the outlet of the valve is opened, is due to the effect of water flow will stick to the filter collection period of part of impurities at mass rinse until discharge water clarity. Shut down again on the outlet of the valve into the normal working condition. 3, backwash drainage backwash, flow diversion valve is closed, the drain valve open, when the water is forced to from the entrance of filter cylinder sandwich mesh into the filter tube of the lateral and shell, reverse from net tube lateral flushing adhesion on the mesh of the impurities, to achieve the purpose of cleaning filter. Due to Industrial Valves closed, the water after recoil valve flow increase, the wash effect is good. Straight through the principle diagram of the automatic flushing sewage
