射流清洗对微灌过滤器滤网清洗效果及损伤研究
Study on cleaning effect and damage of jet cleaning on filter screen of micro-irrigation filter
摘要
Abstract
To investigate the application of jet cleaning technology in the cleaning process of agricultu-ral micro-irrigation filters,the experimental study on jet cleaning was carried out.The influence of 3 parameters,including incident pressure,nozzle diameter,and nozzle diffusion angle,on the cleaning effect of micro-irrigation filter screen and the degree of surface damage.Test results show that the cleaning effect increases with increasing the incidence pressure,nozzle diameter,and nozzle diffusion angle,but the improvement magnitude continuously decreases.The filter surface's damage degree in-creases with increasing the incident pressure and nozzle diameter,and decreases with the nozzle diffusion angle's increase.Variance analysis shows that the order of the impact of the jet parameters on the cleaning effect from the largest to the smallest is nozzle diameter,incidence pressure,and nozzle diffu-sion angle.The degree of influence on the surface damage of the filter screen from the largest to the smallest is nozzle diameter,nozzle diffusion angle,and incidence pressure.Through TOPSIS compre-hensive evaluation,the optimal combination of jet parameters is the incident pressure of 0.3 MPa,noz-zle diameter of 3 mm,and nozzle diffusion angle of 80°.关键词
