By means of filter components of different structure and medium, alternating-filtration experiments under different pressures were carried out, which concluded the basic rule of pipe-filter described by the formulas as below: the formulas of the filter-rate of pure-fluid and suspension; the formulas of resistance under various conditions. Meanwhile, the effects caused by filter components with various structures during the course of filtration have been tested and analyzed. The results of the experiments show that each kind of filter component has their distinctive advantages. For example, the spring-pipe filter component can form stable filter cakes and the support model filter component has self-cleaning effects on filter cakes.
