Description
技术领域
本发明涉及一种润滑油组合物，具体涉及一种极压长寿命汽轮机润滑油组合物。
背景技术
蒸汽汽轮机是一种将蒸汽的热能转变为旋转机械能的高速旋转式热能动力机械，它的润滑部位主要是变速箱和转子轴承。因其转子轴封有可能窜汽，故该润滑系统进水的可能性较大，再加之设备转速高、负荷大、运行周期长，故对油品的防锈性、抗乳化性及抗氧化性的要求都很高。而燃气轮机利用燃烧产生的燃气直接做功，不同于常规蒸汽轮机由燃烧加热产生蒸汽做功，燃气轮机润滑油受轴承热表面的作用并在调速系统高压下使用，应具有优异的氧化安定性和热稳定性、良好的防锈和抗乳化性能，对于齿轮传动的汽轮机，还应具备好的极压抗磨承载能力等，特别是蒸汽-燃气联合循环系统所用的汽轮机润滑油，既要满足蒸汽轮机润滑要求，也要满足燃气轮机的润滑使用要求。因此， 对具有较高承载能力的长寿命汽轮机润滑油的需求变得越来越高。
发明内容
为解决上述问题，本发明提供了一种极压长寿命汽轮机润滑油组合物，具有优异的氧化安定性、高温稳定性、极压性能和防锈性。
