摘要 为了研究喷枪喷出液体的雾化粒径随压力与扇面孔开度变化的特性,搭建了以PC机—激光粒度仪—喷枪—压力源为主体的实验台进行实验。实验表明,在其他条件不变时,随着喷枪接入压力源的不断增大,可以认为雾化粒径逐渐减小,雾化效果越好;在其他条件不变时,随着喷枪扇面孔的开度增大即扇面孔压力增大,雾化粒径并不是总在减小,雾化效果在某一段压力值下反而变得不好。当压力增大到4 bar后,喷雾粒径随压力增大无明显变化。 In order to study the characteristics of the atomized particle size of sprayed liquid from spray gun with the change of the pressure and the opening of the fan face,the experiment was carried out with a PC-laser particle size analyzer-gun-pressure source as the main experimental platform.Experiments show that,when other conditions are constant,as the pressure source of the gun is continuously increased,it can be considered that the atomization particle size is gradually reduced,and the atomization effect is better;when other conditions are constant,with the spray fan face opening increase,the pressure of the fan face is increased,the atomization particle size is not always reduced,and the atomization effect becomes bad under a certain pressure value.When the pressure is increased to 4 bar,the spray particle size does not change significantly with increasing pressure.
