| Message: | Full automatic self cleaning filter housing systemFull automatic back washing filter housing BCM seriesBCM full automatic back washing filter housing is suitable for filtering high flow, high speed, low viscosity fluid particle impurity. BCM full automatic back washing filter housing is a mechanical and electrical products, with advantages of reasonable design, high filtration efficiency, low operating costs, continuous filtration in back washing process, etc., which is widely used in metallurgy, chemical, electric power, oilfield injection water, ballast water, environment-friendly water treatment, etc..Working principle of BCM full automatic back washing filter housing:The filtered liquid is flowing from the inlet to the filter housing, then going through the fixing plate into the filter housing, the liquid flows from the filter element inside to the outside, and then flows out from the filter vessel outlet; Impurities produced from back washing filter flows out from the sewage outfall.How it works?When liquid flows through the filter element, the solid particles will be trapped in the inner side of the filter element. With the increase of pollutants, the differential pressure between the contaminated side and the clean side of the filter is gradually increasing. When the differential pressure reaches the set value, the differential pressure meter sends a message and the filter housing starts automatic back washing process.back washing process:1.Gear motor drives washing arm to turn round by the jackshaft, the rotation angle of the washing arm is controlled by a photoelectric positioning switch, which will make it align to the cleaned filter.2.The drain valve is opened, so that differential pressure will form between the filter element of the outside (clean side) and pollutant drainage.3.Under the action of pressure difference, liquid flow of the clean side will flows from cleaned filter outside to inside to carry out back washing process, pollutants accumulated in the inn......url:http://www.sffiltech.net |
