The anti-wear hydraulic oil and the hydraulic medium used by the hydraulic system utilizing the hydraulic pressure energy play roles of energy transfer, wear resistance, system lubrication, corrosion resistance, rust resistance, cooling and the like in the hydraulic system. For antiwear hydraulic oil, the requirements of a hydraulic device on the viscosity of liquid at working temperature and starting temperature are firstly met, and the viscosity change of lubricating oil is directly related to hydraulic action, transmission efficiency and transmission precision, so that the viscosity-temperature performance and shear stability of the oil are also required to meet various requirements proposed by different purposes. A great deal of facts show that more than 90% of hydraulic faults are caused by working media, so that the correct selection and use of the hydraulic media have very important significance for improving the working performance, working reliability and safety of a hydraulic system and prolonging the service life.
The conventional antiwear hydraulic oil can ensure normal operation of equipment in a relatively mild working environment, but in areas with large temperature difference between day and night in the field and winter in cold north, the problems of unsmooth oil supply, insufficient pressure, equipment operation jitter, blockage and the like are caused because the low-temperature fluidity cannot meet the harsh external environment.
