Plastic bag filter housing is a filtration system which is produce with 100% PP (polypropylene )，taking advantages of excellent PP material, can be used for filtering a lot of chemical sour soda liquids. It is really an economical and practical fine product, as it has no seam, no dead angle, accurate specification with high-quality, high capacity and efficiency. ---The inner-side is very smooth, no ditch, no dead angle, easy to wash; ---P- handle on the cover helps to open the top cover and change materials; ---2"-4" FLANGE Inlet and Outlet; ---The bag has a grip respectively, very convenient to change, safe and clean; ---Working pressure can reach 7kg/cm2 (design pressure 15kg/cm2), operate temperature can be up to 43 ℃/ 110F (material able to bear 83 ℃); ---Please operate in accordance with the condition of standardizing , make sure not to exceed pressure limit or temperature limit. Automatic back wash filter housing working principle: FQ automatic back wash filter housing, The filtered liquid flow in the housing, filtered by the filter screens, the impurities are trapped inside the filter screens. when the impurities become more and more, and the pressure difference between the contaminat side and clean side will be increase. When the pressure difference reaches the set value, the differential pressure gauge will signal, and the filter system will start to back wash the filter screens, and then the clean liquid flow out from the housing, the impurities will be discharged by the drain valve. Automatic back wash filter housing working process: 1) The gear motor drive the intermediate shaft and the washing arm do rotation together.the positioning switch control the The rotation angle, and let the point is meet with the cleaned filter screens. 2) Opening the drain valve, and there will be pressure difference between the drain outlet and clean side(outside the filter screens). 3) Because of the pressure difference, the liquid in the clean side will flow to the filter screens inside from the outside of the filter screens, and then the filter system will start to back wash the filter screens, and the impurities will be washed down and discharged from the drain valve. 4)The time of back washing can set by yourself, when the time is up to the setting value, the drain valve will be closed, and back washing process of this group of filter screens is over, and then the next back washing process of other groups of filter screens will be start. 5)When all the filter screens are cleaned, the Zero switch will control the washing arm to original position, and the filter system will stop back washing and continue thefiltration process. Because the back washing process is proceed one group by one group, so the filter system will keep the filtration working all the time. The back washing process setting: * Setting the pressure difference: There is a differential pressure gauge in the filter system, you can set the valve by yourself. * Setting the time: There is a Time setting device in the filter system, you can set the start time of back washing and the time of duration. If you set the pressure difference and also the time, the setting pressure difference will have priority. * Manual operation: when you are debuging and maintaining the filter system, you can press the "TEST" button, and start the back washing process. Automatic back washing filter housing standard performance: Min. working pressure: 2 bar (30 psi) Max. working pressure: 7 bar (100 psi) Pressure drop: 0.1bar (2 psi) Working Temp.: 65°C (149°F) Micron rate: 25-3000 micron Control voltage: 24V DC Washing consumption(in the Min. working pressure condition): 50kg Housing material: Carbon steel (spraying), 304SS/316SS(Blasting) If you have any inquiry for filtration products, please feel free to contact with us.
