技术领域
本发明涉及石油化工领域,特别涉及一种高清洁抗磨液压油。
背景技术
现有抗磨液压油基本按照国家标准GB11118.1中对抗磨液压油的质量要求生产,在此标准中并未对清洁度提出明确要求,也未对抗磨性能中的磨斑直径和极压性能中的最大无卡咬负荷、烧结负荷和综合磨损值提出要求,因此按此标准生产出来的液压油性能质量差异很大。清洁度对于液压设备来说非常重要,颗粒物过多会导致液压设备中的滤网堵塞,造成流动不畅,传递效率下降,设备功率下降。抗磨性能和极压性能对于高压的液压设备来说也非常关键,因为设备零部件在高压情况下间隙会更小,会承受更大的摩擦磨损的风险。因此对于一款高档的抗磨液压油来说,高清洁和高抗磨性能能带来性能更加优异的产品。
