Hydraulic oil is a hydraulic medium used in hydraulic systems that use liquid pressure energy. It plays an important role in energy transfer, wear resistance, system lubrication, corrosion protection, rust protection, and cooling in hydraulic systems. For hydraulic oil, first of all, the hydraulic device should meet the requirements of liquid viscosity at operating temperature and starting temperature. Since the viscosity change of lubricant is directly related to hydraulic action, transmission efficiency and transmission accuracy, It is also required that the viscosity and shear stability of the oil should meet the needs of different applications. There are many types of hydraulic oils and different classification methods. For a long time, they have been used to classify by use, and they have also been classified according to the type of oil, chemical composition, or flammability. These classification methods only reflect the earning of oil products, but lack of systematic, and it is difficult to understand the relationship and development between oil products.
