过滤器过滤面积通常指丝网的有效流通面积,可以查阅下表“滤网规格”得知有效面积,滤网总面积与有效面积率的乘积即为过滤面积(有效流通面积)。通常,考虑过滤面积按过滤器公称通径的20倍设计,已足够满足使用场合。除非在非常见的特殊环境使用,才予以特殊考虑。
The filtration area usually refers to silk screen's effective flow area, May the consult next table “the mesh specification” knowing effective area, Mesh total area and active surface rate product namely for filtration area (effective flow area). Usually, The consideration filtration area according to the filter nominal size's 20 time of designs, enough has satisfied use situation. Only if in non- the common special environment use, only then gives the special consideration.
过滤器过滤网孔目数(目数/英寸)的选择,主要考虑需拦截的杂质粒径,依据介质流程工艺要求而定。各种规格丝网可拦截的粒径尺寸查下表“滤网规格”。
Hole Mesh (mesh / inch) of choice, consider the need to intercept the main impurities in diameter, according to media flow Process requirements. Various specifications of wire to intercept the particle size can search under the table "filter specifications."
