Direct backwash filter for sale in Changzhou

Direct backwash filter for sale in ChangzhouIt is a water treatment equipment that integrates filtration and self-cleaning functions. Its core design is to achieve reverse flushing of the filter screen by changing the direction of water flow, and discharge can be completed without stopping the machine. The main body of the equipment is usually composed of a carbon steel or stainless steel cylinder, a wedge-shaped filter screen, a directional valve, and a sewage device. After the water enters from the inlet, impurities are intercepted by the filter screen, and clean water flows out from the outlet. When the filter screen is clogged, by closing the steering valve and opening the drain valve, the water pressure in the pipeline is used to reverse the flow of water and flush the filter screen, removing impurities and restoring the filtering performance.

Direct backwash filter for sale in ChangzhouThe opening mechanism of the water flow guide valve is divided into two types: manual and electric. When using an electric opening mechanism, a clock controlled electrical control box is installed, which can automatically clean and discharge according to the set time requirements. At this time, the discharge outlet is equipped with an electric ball valve, water flow guide valve, and discharge electric ball valve to achieve linkage.

Installation and use:

Backwash filters should be installed horizontally or vertically. When installed vertically, the direction of water flow should be from top to bottom; During installation, it should be noted that the direction of the arrow on the casing must be aligned with the direction of the water flow. During normal operation, the water flow guide valve is in the open position. When discharge is required, close the water flow guide valve and open the discharge valve until the water quality becomes clear. Close the discharge valve and open the water flow guide valve to complete the discharge process and the equipment enters normal operation.
