Hydraulic system of the basic requirements of hydraulic oil |
1. The right viscosity, good viscosity-temperature characteristics. General hydraulic oil viscosity is usually 15 to 68mm2 / s between. 2. texture pure, impurity less good lubrication properties. 3. of metals and seals have good compatibility, anti-foam, anti-emulsification, anti-corrosion and rust good. 4. to heat, oxidation, hydrolysis and good shear stability. 5. volumetric expansion coefficient of small, large heat capacity. 6. hydraulic A> oil flow and low freezing point, flash point and high-lighted. 7. on the human body without harm, and low cost .
