| 全自动机械过滤器工作原理 Working principle of automatic mechanical filter 机械过滤器筒体内以不同粒径的滤料，从下至上按大小压实排列。当水流自上往下流过滤层时， 水中含有的悬浮物质流进上层滤料形成的微小孔隙，受到吸附和机械阻流作用，悬浮物被滤料表层所截留。同时，这些被截留的悬浮物之间又发生"重叠"和"架桥"作用，在滤层表面形成薄膜，继续发生过滤作用。这即是所谓滤料表层的薄膜过滤效应。这钢制闸门 钢坝 保定轻钢别墅 保定平面设计培训 保定室内设计培训 保定办公家具 保定空调维修 种薄膜过滤效应不但表层存在，而当水流进入中间滤料层时也产生这种截留作用。与表层的薄膜过滤效应不同的是，这种中间截留作用称之为渗透过滤作用。 In the mechanical filter barrel, the filter materials with different particle sizes are compacted and arranged according to the size from bottom to top. When the water flows through the filter layer from top to bottom, the suspended substances in the water flow into the micro pores formed by the upper filter material, and are subject to adsorption and mechanical resistance, and the suspended solids are intercepted by the surface layer of the filter material. At the same time, the "overlap" and "bridge" effects occur between these intercepted suspended solids, forming a membrane on the surface of the filter layer, and continue to filter. This is the so-called membrane filtration effect on the surface of the filter material. This kind of membrane filtration effect not only exists in the surface layer, but also in the middle layer of filter material. Different from the membrane filtration effect of the surface layer, this intermediate interception is called osmotic filtration. |
