摘　　要：为了揭示微量润滑系统的喷射雾化规律,采用基于激光多普勒效应的三维粒子动态分析仪测量了油滴雾化特性。针对3种可降解绿色润滑油——三羟甲基丙烷三油酸酯、植物油6000和聚乙二醇400,测试得到了不同的油量、空气流量和截距条件下的雾化锥角及油滴大小、速度、数量的分布规律。试验表明,喷雾锥角主要由喷嘴结构决定,油滴数量基本符合正态分布且空气流量和油量对油滴数量影响较大,油滴速度分布曲线呈钟形且射流中心速度最高。该雾化分布特性对实施微量润滑加工具有重要的工程意义。To reveal the spray atomization rule of the minimum quantity lubrication system,a three-dimensional particle dynamic analyzer based on laser Doppler effects was used to measure the atomization characteristics of oil droplets.For the three degradable green lubricating oils— trimethylolpropane trioleate,vegetable oil 6000 and polyethylene glycol 400,the atomization cone angle and distribution law of oil droplet size,speed and quantity under different oil volume,air flow and intercept conditions were tested.Experiments show that the spray cone angle was mainly determined by the nozzle structure,the number of oil droplets basically conformed to the normal distribution,and the air flow and oil quantity had a greater influence on the number of oil droplets,the oil drop velocity distribution had a bell-shaped curve and the jet center velocity was the highest.This atomization distribution characteristic had important engineering significance for the implementation of minimum quantity lubrication processing.
