摘　　要：简述了气力式雾化喷头的基本结构及工作过程,并对喷头的雾化特性进行了初步试验。试验结果表明,雾滴大小及均匀性随着气体压力的升高而减小;喷孔结构和参数对雾滴直径及雾化质量有重要影响;该喷头所得雾满尺寸满足静电喷雾要求,为静电喷雾的正常进行提供了前提。The structure and spraying mechanism of the pneumatic energy electrostatic nozzle are simply introduced, and then the atomization properties of this nozzle is studied. The results indicate that the higher the air pressure is, the smaller the droplet diameter is, that the structure and parameters of the nozzle have a great effect on its atomization properties, and that the size of droplet obtained from this nozzle can meet the need of electrostatic spraying, thus a good foundation is built for later experiment of electrostatic spraying.
