    摘要:

    對研制的氣液兩相感應(yīng)式靜電噴頭進(jìn)行了性能試驗(yàn)研究。結(jié)果表明：與常規(guī)噴霧相比,，霧滴在葉片正面的沉積量和覆蓋率分別增加了43.03%和22.07%,，且在葉片背面覆蓋率達(dá)30.95%,；當(dāng)氣體流量為1.4 m3/h，噴量為60 mL/min,，電壓為1000V時(shí),，荷質(zhì)比可以達(dá)到3.2mC/kg，可以有效增加荷電沉積,；最優(yōu)工作參數(shù)組合為氣液比0.18,、噴霧角度0°、電壓1000 V,。

    Abstract:

    The performance research on a two-phase gas-liquid electrostatic induction nozzle was carried out in the lab. The results showed that the droplets deposition and coverage ratio on the upper leaf surfaces achieved by electrostatic spraying were increased by 43.03% and 22.07%, respectively. The coverage ratio on the down leaf surfaces was up to 30.95%; when gas flow rate was 1.4m3/h, liquid flow rate was 60mL/min, voltage was 1000 V, chargetomass ratio could reach to 3.2mC/kg, which was high enough for electrostatic spraying. The optimum work parameters were: gasliquid ratio of 0.18, spraying angle of 0°, and voltage of 1000 V. 
