LSQ automatic self-cleaning water filters an overview of automatic self-cleaning water filters LSQ from Germany, Israel and other countries of similar products technology, combined with the actual situation of China's hydropower optimization refined, its unique two sewage, water technology vena adoption, can solve the conventional water filters due to plastic foam, branches, plants and other floating debris produced jam, paste network problems; and the lower the water easy way to filter sediment burst into the lumen to the filter effect is reduced , paste net frequently, the normal continuous working time shortened. Aside in the electrical control of conventional logic control, PLC programmable control method to achieve water filter in-line filters, self-cleaning, grading sewage functions. LSQ automatic self-cleaning water filters can continue to the river, the water filtration equipment to clean water for hydropower, hydropower equipment to ensure safe and reliable operation for a long time. It is both in the design and manufacture of technology or in the practical application performance, are beyond the domestic and foreign products. Second, the technical parameters Nominal pressure: 1.0MPa 1.6Mpa Power supply: 380VAC 50Hz Working medium: Water pressure loss: 0.11Mpa filtering accuracy: 0.1-6mm recoil flow: less than 20% water filter and drain valve flange standard total flow : GB9119-2000
