液压油防锈性能研究

Study on Antirust Performance of Hydraulic Oil

液压设备种类繁多、工况复杂、使用环境多变,针对液压油进水之后的防锈性要求,通过比较工业润滑油与水相关的评价方法,尤其是对比国内外液压油标准中防锈性能要求,确定最为严格的评价手段。通过48 h合成海水液相锈蚀和水洗防锈试验筛选液压油,为海洋、隧道等苛刻工况下的液压系统要求提供用油指导。

There are many kinds of hydraulic equipment,complex working conditions and variable operating environments.In view of the rust prevention requirements of hydraulic oil after water inflow,the most stringent evaluation method is determined by comparing the evaluation methods related to industrial lubricating oil when it meets water,especially the rust prevention performance requirements in domestic and foreign hydraulic oil standards.Through the 48-hour synthetic seawater liquid phase corrosion and water washing rust prevention test,the hydraulic oil is screened to provide oil guidance for the hydraulic system requirements under harsh working conditions such as ocean and tunnel.
