product description

P-type backflushing sewage filter is suitable for various water supply systems, process water systems and industrial cooling water systems, especially 24-hour non-stop systems, which can filter out various mechanical impurities in water and ensure the safety and reliability of system equipment. run.

Structure and working principle
P-type recoil sewage filter is mainly composed of high-quality carbon steel cylinder, stainless steel wedge-shaped filter with special structure, butterfly valve and sewage equipment. When the filter is working, the butterfly valve is in the open state, the water flow enters the filter from the inlet, and is filtered to the outlet through the filter screen. When the filter needs to discharge sewage, close the butterfly valve and open the sewage valve. The water flows through the first half of the filter screen to filter, part of the water flow enters the system from the outlet, and the remaining water flow flows from the outside of the second half of the filter screen to the inside, and is discharged through the sewage outlet. The function of automatically flushing the filter screen. The entire flushing process system works without downtime.

installation and use

P-type recoil sewage filter should be installed horizontally or vertically. When installed vertically, the direction of water flow should be from top to bottom. When installing, pay attention to the direction of the arrow on the casing must be consistent with the water flow. During normal operation, the butterfly valve is in the open state. When sewage needs to be discharged, close the butterfly valve and open the sewage valve until the discharged water becomes clear. Closing the blowdown valve and opening the butterfly valve completes the blowdown process and the equipment enters normal operation.
