The u-zc-x1 / x2 series sucking scanning self-cleaning filter is divided into vertical and horizontal structures. Through a decelerating motor driven cleaning mechanism, which contains a unique multi-layer all stainless steel filter screen, the filtering accuracy can reach up to 10 microns; the sucking scanning technology consumes less than 1% of the total water. It is the lowest discharge water consumption rate of all self-cleaning modes (this rate is adjusted according to the specific application). Product features: 1. Compact body, solid and reliable structure; 2. The backflushing water consumption is small and the required water pressure is low; 3. High filtering accuracy, suitable for all kinds of water quality; 4. The pressure drop during backflushing is small, which does not affect the water supply. working principle: Filtration process: water enters from the filter inlet and passes through the coarse filter screen from the outside to the inside, and then flows out from the inside of the fine filter screen. Impurities in this process are intercepted by the fine filter screen and form a certain head loss. The coarse filter screen is designed to protect the cleaning mechanism from damage by large particles of impurities, which does not play a filtering role. Self cleaning process: when the pressure difference inside and outside the filter screen reaches the preset value or the timing cleaning switch reaches the set time, the system starts the self-cleaning process. The whole cleaning process is completed by a sucking scanner, which carries out a spiral scanning movement to suck down the impurities on the inner surface of the filter screen and discharge them through a blowdown valve. The scanner is driven by a two-way rotating electric motor through a screw rod. The opening of the blowdown valve is controlled by a two position three-way solenoid valve. The whole blowdown process lasts for about 35 seconds, and the system is not cut off in this process. Installation diagram and pressure loss table:
