Aimed at some problems such as short spraying distance , electricity - leaking and reverse ionization among electrostatic nozzles existing in the country , a induction charging and pneumatic energy electrostatic nozzle was designed . the basic designing theories , structure and working process of this nozzles were theoretically specified in the paper . and then the atomization quality and charge performances of this nozzle and its affecting factors were studied by carrying out performance experiment and statistic analysis . result of the studies indicate : ( 1 ) some progress were made in solving the problems list above ; ( 2 ) from this nozzle , droplet were minute and uniform , and higher charge - mass ratio can be obtained under lower electrostatic voltage , thus the atomization quality and charge performance of this nozzle were both better ; ( 3 ) within the experiment extend , air pressure at 0 . 2mpa , electrostatic voltage at 2400v were the most suitable parameters for the nozzle ; ( 4 ) the regression equations for describing droplet size , intensity of spray current and charge - mass ratio of this nozzle obtained from the experiment data had higher forecast precision ; ( 5 ) cross - effect of all factors were not significant , the atomization quality and charge performance were relative dependency affected by the factors 诸试验因素中,充电电压和喷孔直径对雾滴荷质比均有极显著的影响;气体压力和液体流量对雾滴荷质比的影响均不显著;影响雾滴荷质比的主要因素依次为充电电压和喷孔直径; ( 8 )在300v 、 600v 、 1200y 、 1800y 、 2400v 、 3000v六种充电电压t ,雾滴荷质比先随充电电压的增加而增大, 2400v后荷质比减小,推测:对于所研制的喷头可能存在一个最佳充电电压; ( 9 )由充电电压和喷孔直径的不同搭配所得雾滴荷质比不同这一结果,可看出,较大充电电压需配备较大喷孔直径以增强雾滴荷电效果; ( 10 ) td3 . 6和td3 . 4两喷头的雾滴荷质比曲线趋于重合,说明喷孔直径大于沪3
