摘要
随着汽轮机和透平机械等设备的发展,涡轮机油的运行工况变得更加苛刻,油品容易发生异常氧化,并出现漆膜问题。油溶性聚醚分子具有极性,理论上对漆膜等极性氧化产物具有溶解性。为探究用油溶性聚醚改善涡轮机油漆膜问题的可行性,采用高温烘箱氧化、Dry-TOST模拟氧化、油品性能分析和橡胶相容性实验等方法,评价油溶性聚醚对涡轮机油漆膜倾向指数、油泥生成量及关键理化性能的影响,以及与密封材料间的相容性。结果表明:油溶性聚醚具有减少涡轮机油油泥生成量,降低漆膜倾向指数的作用;油溶性聚醚对涡轮机油的旋转氧弹、空气释放性、橡胶相容性具有一定不良影响,但添加一定比例油溶性聚醚的涡轮机油样品的理化性能满足技术指标要求,并可通过橡胶相容性实验。将油溶性聚醚作为涡轮机油的组分以提升其抗漆膜沉积性能的技术具有一定工业推广价值。
With the development of steam turbine,turbomachinery and other equipment,the operating conditions of turbine oil become more severe.As a result,the turbine oil is easy to occur abnormal oxidation and lead to varnish.Due to the polarity of molecules,oil-soluble polyether has solubility for polar oxidation products theoretically,such as varnish.In order to explore the feasibility of using oil-soluble polyether to improve turbine oil varnish resistance property,high temperature oven aging,Dry-TOST tests,oil properties analysis and elastomer compatibility tests were used to examine the effect of oilsoluble polyether on insoluble color bodies,sludge amount and other key properties of turbine oil samples,and the compatibility tests between oil samples and elastomeric materials.Results show that oil-soluble polyether as a component of turbine oil has the benefit of reducing insoluble color bodies and sludge amount.Oil soluble polyether has certain adverse effects on the rotary bomb oxidation test,air release and rubber compatibility of turbine oil,but the physical and chemical properties of turbine oil samples added with a certain proportion of oil soluble polyether meet the technical requirements of turbine oil and the requirements of rubber compatibility test.The technique of using oil-soluble polyether as a component of turbine oil to improve its varnish resistance property has certain industrial application value.
