Problems solved by technology

[0004] With the development and wide-scale use of hydraulic machinery, as well as the development of human beings in areas with harsh environments, the hydraulic system will face more tests from the working environment, so the hydraulic system has higher and higher requirements for hydraulic oil. Oil can not fully meet the needs of hydraulic machinery, so it is necessary to develop an anti-wear hydraulic oil with high comprehensive performance and reasonable price, so that it has good wetting performance and oxidation stability, and prolongs the service life of hydraulic oil and hydraulic components; At the same time reduce the number of oil changes, improve the working efficiency of hydraulic machinery, and achieve the purpose of energy saving and environmental protection
