Pneumatic Atomizer Design and Droplet Characterization for MQL in Metal Cutting
雾化器作为内置式雾化型微量润滑(MQL)装置的核心部件,其性能直接影响润滑油的雾化效率与切削加工效果.基于液体喷雾学理论,深入分析了润滑油雾化机制及影响雾化器性能的关键因素,研发了一种气动雾化型MQL油雾化器.结合雾化器性能评价方法与实验研究,明确了喉管直径、吸油管孔径及孔壁间隙对雾化器性能的耦合作用机理.基于激光喷雾粒度仪数据,验证了雾化器在不同黏度油品下的优异雾化表现,雾粒直径的数量频度分布集中在0.8～10 µm之间,体积频度分布峰值位于25 µm,索特平均直径D32 为5～12 µm.
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.
