The basket filter produced by Shenyang Wensheng consists of connecting pipe, barrel body, filter basket, flange, flange cover and fasteners. It can clear out bigger solid impurities when installed on the pipe, which can keep the equipment (including compressor and pump) and appearance work normally. Finally the stable technology process has been met and the function of safe production is ensured. Application range: 1 Weak corrosive material in the manufacture of petroleum and chemical industry: such as water, oil, ammonium and hydrocarbon 2 Corrosive materials in the manufacture of chemical industry: such as caustic soda, soda ash, concentrated and dilute sulfuric acid, carbonic acid, acetic acid and so on 3 Materials with low temperature in the refrigeration system: such as liquid methane, liquid ammonia, liquid oxygen and all kinds of cryogen Main technical parameters: 6 Sealing materials: PTFE, acrylonitrile-butadiene rubber, oil-proof asbestos rubber 7 Manufacturing testing standard: HGJ532-91 Selection principle: 1 Path of exits and entrances: In principle, the path of exits and entrances of basket filter should not be lesser than the one of path of entrances of matching pump, generally as same as the caliber of entrance piping. 2 Nominal pressure: The pressure rating of filter is defined according to the possible highest pressure of the filtration pipe. 3 Selection of cell density: The particle diameter of impurities, needs to be held up, should be defined according to requirement of medium process technology.
