摘　　要：为探究射流清洗技术在农业微灌过滤器清洗过程中的应用,开展射流清洗试验研究,分析入射压力、喷嘴口径、喷嘴扩散角度等3个参数对微灌过滤器滤网清洗效果及表面损伤程度的影响规律.试验结果表明:清洗效果随入射压力、喷嘴口径、喷嘴扩散角度的增大而提升,但提升幅度不断减小;滤网表面损伤程度随入射压力、喷嘴口径的增大而增大,随喷嘴扩散角度的增大而减小,其幅度逐渐减小;通过方差分析可知,射流参数对清洗效果影响程度从大到小依次为喷嘴口径、入射压力、喷嘴扩散角度,对滤网表面损伤影响程度从大到小依次为喷嘴口径、喷嘴扩散角度、入射压力;通过TOPSIS综合评价得到最佳射流参数组合为入射压力0.3 MPa,喷嘴口径3 mm,喷嘴扩散角度80°.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 increases 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 diffusion 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 comprehensive evaluation,the optimal combination of jet parameters is the incident pressure of 0.3 MPa,nozzle diameter of 3 mm,and nozzle diffusion angle of 80°.
