润滑油真空分离与聚结分离脱水的对比试验研究

摘要

The elaborates working principle and test methods of lubricants dewatering based on vacuum separation and coales-cence separation,selecting the L-TSA46 turbine oil as the text object,designing the contrast test under the same experimental con-ditions.The results suggest:the coalescence has higher efficiency of separation and consumes lower energy than vacuum when the moisture content is higher than about 2 ×10 -4;The vacuum has higher efficiency of separation and consumes lower energy than coalescence when the moisture content is less than about 2 ×10 -4;Only the vacuum separation can be used when the moisture content is less than 6 ×10 -5 .%阐述了润滑油真空分离与聚结分离脱水的工作原理及试验方法，选取 L-TSA46汽轮机油作为试验对象，在相同条件下进行了对比试验，结果表明：当含水量高于约2×10－4采用聚结分离比采用真空分离效率高、能耗低；当含水量低于约2×10－4采用真空分离比采用聚结分离效率高、能耗低；当含水量低于6×10－5则只能采用真空分离。
