Optimization of Ultrasonic Atomization by Electrolytic Polishing

Because of structural simplicity, low production costs and small atomizing droplets, ultrasonic atomization used in aerospace, medical, energy saving and other fields. With the increasing need to increase improve the atomization efficiency, Researchers have made a lot of efforts. However, the micro-tapered hole group on atomizer has not been deeply studied. In this study, the electrolytic polishing processing is proposed to improve the quality of the micro-tapered holes. First, a mathematical relation of atomization amount and polishing time was established. Second, the relevant parameter were measured using a microscope. Lastly, the mathematical relation was determined and revised through an atomization amount experiment. The experimental results show that when the polishing time is 4 min, the atomization amount reaches the maximum of 4.53 ml/min, which is much higher than that of the untreated atomizer. This study demonstrates that polishing can effectively remove burr in the process of hole machining, which will further improve the atomization efficiency of atomizers.
