Abstract：In order to study the influence of air pressure and water pressure on the particle size parameters of ultrasonic atomization spray,an experimental platform was designed in this paper.Anionic surfactant rapid infiltration T was selected to configure a solu-tion with a concentration of 0.07%for experiment.The changes of particle size parameters of ultrasonic atomization spray under dif-ferent combinations of air pressure and water pressure were analyzed.The experimental results show that the particle size paramet-ers D10,D50,D90,VAD,SMD and NAD decrease with the increase of air pressure,and the decrease is affected by water pressure.At the same time,the above particle size parameters also increase with the increase of water pressure,and the increase will also be af-fected by air pressure.The influence of air pressure on the change of droplet size is greater than that of water pressure.When the pressure changes,the change trend of particle size parameters D10 and NAD is highly consistent,and the increase of particle size of D50,VAD and SMD is highly consistent.
