Based on design of automatic self-cleaning filter on industrial scale (50 m3/h), the design and optimization procedures of several operation parameters are presented and a model of filter is obtained as well,then to calculate control parameters of control system.The main research contents are following as:A auto control self-cleaning filter on industrial scale( 50m 3/h) , work pressure(1.6-2.5Mpa) , filtration accuracy(0.1-200μm), filtration surface(10㎡) , Motor power(5.5 KW) and work temperature(-5 ℃ - 105 ℃)has been designed . auto control self-cleaning filter drive itself to clean completely by its pressure of filtrated liquid and without stop.Volume of the filteris so little and precision can be modulated to fit for kinds of industry produce. In this paper, a suit of drawing and design procedures of such filter has been given.Mechanism during filtration in the filter has been studied are obtained 二、设计意义过滤机是利用多孔性过滤介质，截留液体与固体颗粒混合物中的固体颗粒，而实现
