襄陽襄城襄州區(qū)美孚68號液壓油-傳動油經(jīng)銷者Antiwear hydraulic oil (HM hydraulic oil) is developed from rust-proof and oxidation-resistant hydraulic oil. It has a series of such as high zinc alkaline, low zinc alkaline, high zinc neutral and ashless. They are divided into four grades of 22, 32, 4 and 68 according to the kinematic viscosity at 40 ℃. (1) Appropriate viscosity and good viscosity-temperature performance to ensure that the hydraulic components well lubricated, cooled and sealed under changing working pressure and working temperature. (2) Good extreme pressure anti-wear performance to ensure normal lubrication of friction pairs in pressure and high speed harsh conditions such as oil pump, hydraulic motor, control valve and cylinder, and reduce wear. (3) Excellent oxidation stability, hydrolysis and thermal stability to resist the effects or actions of air, moisture and high temperature and high pressure, so that it is not easy to age and deteriorate, and to extend the life
