摘　　要：研究了在感应荷电状态下环形电极的直径和安装位置对雾滴荷电性能的影响,试验在相同的喷雾压力和液体介质的条件下进行,采用5种电极环径和5种安装位置进行全因素射流荷电喷雾,应用网状目标法测量群体雾滴电流,用荷质比评价感应荷电性能,详细分析荷电电压、电极环直径和安装位置对荷电量的影响。试验结果表明:荷电量与荷电电压成正比并随电极的安装位置前移而增大、电极环直径的增大而减小,并且存在明显的线性关系;通过进一步分析,提出荷电系数计算经验公式。The electrode diameter and installation position of ring electrode in the state of charged induction will affect the charging performance of droplets. The experiment was conducted in the condition of the same spray pressure and liquid medium by selecting five electrode ring diameters and five installation positions for all -factor jet charged spray and using the net target method to measure the current of group droplets and the charge - mass ratio to evaluate the induction charging performance so as to analyze in detail the effect of charging voltage, electrode ring diameter and installation position on charging volume. The findings indicate that the charging volume is proportional to charging voltage and increases with the forwarding of electrode installation position and decreases with the increase of electrode ring diameter and in addition, a clear linear relation was found. Further analysis yielded computational empirical formulae for charging coefficient.
