气力式感应型静电喷头雾化锥角正交试验研究

摘要

针对目前现有静电喷头雾化效率低、雾化锥角较小等问题，通过改变静电雾化过程中气力式感应型静电喷头的液压、气压和静电压，并对其进行了正交试验设计，获得了不同因素水平下的雾化锥角。利用 SPSS 软件进行数据分析，最终得到最优的试验因素组合气压0．25MPa，液压0．05MPa，电压-1000V，并通过方差分析得到影响雾化锥角最显著的试验因素。试验结果表明：气压和液压对喷头的雾化锥角有一定的影响，电压对雾化锥角的影响较小。%For the low efficiency of the existing electrostatic nozzle atomization spray cone angle smaller issues such as this article by changing the electrostatic air force induction type electrostatic nozzle atomization process of hydraulic , pneumatic and static voltage and its orthogonal experimental designlevel of different factors under the the atomization cone angle results.SPSS software for data analysis , and ultimately get the optimal test combinations of factors Pressure 0.25Mpa hydraulic 0.05MPa voltage-1000V, the most significant impact of the spray cone angle and by analysis of vari-ance test factors , test results show that:the pneumatic and hydraulic nozzle spray cone angle of impact , the voltage on the spray cone angle smaller .
