Straight-through automatic sewage filter ( ZPG-I )

summary

ZPG automatic backwashing reader to overcome the traditional filter products pollution minimum, easy to dirt blockage, filter part need to remove cleaning failed to monitor the filter status, and many other shortcomings, with the filtration of raw water and automatic cleaning filter discharge function, and cleaning system uninterrupted water supply, can monitor the working state of the filter, high degree of automation. Backwash filter can be installed in vertical, vertical, inverted in any direction, can be used in industry, agriculture, municipal power, electronics, medicine, food, printing and dyeing, iron and steel, metallurgy, paper making and other industries water filtration.

operational principle

During normal operation, the diversion butterfly plate is open. At this time, the water enters from the inlet and filters out the particulate impurities through the filter screen. In the filtration process, the filter screen gradually accumulated water quality of stolen goods, miscellaneous

Quality, forming a filter impurity layer. Because the impurity layer accumulates in the lining of the filter screen, a pressure difference is formed on the inner and outer sides of the filter screen. When the pressure difference of the filter reaches the preset value, the cleaning process will begin, and the water supply will continue to flow continuously. When cleaning, first close the diversion butterfly plate in the middle, and then open the discharge valve to start the discharge. When the sewage outlet is discharged, close the discharge valve and open the backflow butterfly plate to complete the discharge. ZPG-L automatic recoil discharge filter should be installed on the direct bending, ZPG-1 automatic backwash discharge filter should be horizontal or vertical installation, when the vertical installation, water flow direction should be top-down, installation should pay attention to the shell arrow to the water direction, normal operation, the butterfly valve in the open state, when need to drain, sewage, close butterfly valve, open the drain valve until the water quality
