| 摘 要： | 设计了一种新型导流式油气润滑喷嘴，测试并比较了该类型喷嘴与普通针型喷嘴的气相参数、射流形态和产生的油滴尺寸及分布。试验结果表明，导流式喷嘴相对于针型喷嘴供油效率高，在保证润滑效果的同时，油气润滑系统的供油量可减少40%左右，压缩空气的消耗量可减少28%左右，降低了能耗，节约了成本。

| Abstract: | A novel guide-type nozzle was designed herein， and some tests were carried out to study air parameters，jet flow properties， droplet sizes and droplet distributions.Comparisons were completed for this new nozzle and classical nozzles.Results show that the guide-type nozzle presents higher oil supply efficiency than that of the classical needle nozzle.For qualified lubrication performances，the new nozzle reduces lubricant supply by 40% and suppresses pressurized air consumption by 28%，which leads to direct energy and cost saving. |
