微量润滑切削用气动雾化器设计及雾化特性研究
Pneumatic Atomizer Design and Droplet Characterization for MQL in Metal Cutting
摘要
Abstract
The atomizer,as the core component of the built-in atomized MQL system,directly af-fected the atomization efficiency of MQL oil and cutting performance.The atomization mechanism of lubri-cating oil and the key factors influencing atomizer performances were thoroughly analyzed based on the liq-uid spray theory herein.A pneumatic atomization-type MQL oil mist atomizer was developed.Through a combination of atomizer performance evaluation methods and experimental research,the coupling mecha-nism of factors such as throat diameter,suction aperture,and gaps between orifice walls on atomizer perfor-mance was clarified.Based on the analysis of the laser spray particle size analyzer,the superior atomization performance of the atomizer with oils of varying viscosities was verified.The particle size number fre-quency distribution is concentrated between 0.8-10 µm,with the volume frequency distribution peaking at 25 µm and the Sauter mean diameter D32 ranging from 5-12 µm.关键词
