FLFCGLQDN25 Automatic (manual) backwash lter With the continuous development of high-end support in coal mines, in the past, common lters were generally used in the lter systems of hydraulic support in coal mines, and the precision of lter screens was not enough or often broken, resulting in various impurities entering the column, dry jin top and various valves, resulting in their service life greatly reduced, which brought great hidden dangers to the safety production of coal mines. It often needs to be replaced or replaced, which increases the labor inten- sity of coal miners and needs to be disassembled and cleaned, which is inconvenient for the use and maintenance of underground coal mines. The high-precision backwash lter with independent intellectual property rights. It can greatly improve production ef ciency and bring great bene ts to coal mine safety production. At the same time, it adopts an integral cartridge structure. At the end of the service life, the entire set of lter element components can be pulled out as a whole, and the valve body can be used continuously, saving costs. (Note: Backwash once during each shift of production handover to prevent long-term non-recoil, Impurities stick to the lter element and affect the lifting and lower- ing speed of the bracket.) The backwash lter produced by our company has been widely used in many mining bureaus and coal mines across the country. The backwash lter is uninterrupted according to different underground conditions, and the use effect is very good. It has been greatly praised by various users and greatly improved. The service life of hydraulic supports and systems is prolonged.
