摘要
抗乳化性能是衡量涡轮机油质量优劣的一项重要指标。针对GB/T 7305水分离性测定法在实际应用中存在的不足,通过模拟实际工况,通过连续分水能力、脱水率和油水比对涡轮机油抗乳化性能的影响,形成一种更能反映润滑油在实际使用的抗乳化性能的评价方法。试验结果表明:A涡轮机油随着测试增加连续分水性能在下降,B涡轮机油分水速度最快且连续分水性能最好,C涡轮机油分水性随着测试增加下降明显。当油水比从1∶1、5∶3、3∶1、7∶1不断升高变化时,涡轮机油油水分离的时间在增长,连续分水能力在下降。通过对油水分散系显微镜图像的观察,得到油水分散系中游离水分布情况与抗乳化性能测试结果一致。
The demulsibility characteristic is an important quality index of turbine oil. As the main detection method of turbine oil demulsibility characteristic, GB/T 7305 has some inadequacy in actual working conditions. By simulating actual working condition, the effect of continuous water separation, the dehydration rate and different oil-water ratio on the demusification performance of turbine oil was investigated. A practical evaluation method that can reflect the demulsibility characteristic of lubricant oils in the practical application was developed. The experimental results showed that continuous water separation performance of lubricant oil A decreased in the test, lubricant oil B had the fastest dewatering speed and the best demulsibility property, water separation performance of turbine oil C significantly decreased in the test. When the oil-water ratio continuously increased from 1:1, 5:3, 3:1 to 7:1, the time of water separation increased, and the continuous water separation capacity decreased. The microscopic images of oil-water dispersion system showed that the distribution of free water in the oil-water dispersion system was consistent with the results of demulsification test.
