【摘要】 利用 91WDC 15 0型风送式喷雾机的样机 ,采用撞击雾滴采集法 ,通过三因素三水平的正交试验和方差分析得出 :喷嘴直径是影响雾滴均匀性的主要因素 ,其次是药液流量和药箱压力 ,并找出了最佳参数组合。分析和总结了雾滴密度和雾滴直径在雾流轴线方向上的变化规律。更多还原

【Abstract】 By using 91WDC 150 Air assisted sprayer, three factors and three levels experiments were designed with bumping droplets collection. It was found through analysis of variance that the diameter of nozzle was the main factor affecting droplets uniformity, discharge rate and pressure in pesticide box were less important factors. The bast parameter combination was verified that the trend of droplets density and droplets size along spray were analyzed.更多还原
