Abstract：The technology parameter of self cleaning filter is compared,and the applied problem of net self cleaning filter in our country is analysed,then a new net self cleaning filter for micro-irrigation is designed,which structure and work principle are introduced detailedly.According to the results of theory calculation,on the condition of 1＜L/D＜5,the quantitative relationship of the diameter,the length and the flow is deduced.According to the experiment results,the quantitative relationship between water head loss and flow is obtained,which compared with the traditional net filter.The results indicate that water head loss of new filter is small,and it is changed slowly along with the flow.Even if the flow is changed widely,the water head loss is small,which represents its superiority.So it has extensive applied foreground in field micro-irrigation technology.
