46# hydraulic oil used in Honggang hydraulic cutting machine:
Hydraulic oil is a hydraulic medium used in hydraulic systems that use liquid pressure energy. It plays the role of energy transmission, anti-wear, system lubrication, anti-corrosion, anti-rust and cooling in the hydraulic system.
For hydraulic oil, the requirements of the viscosity of the hydraulic device at the working temperature and the starting temperature should be met first. The viscosity change of the lubricating oil is directly related to the hydraulic action, transmission efficiency and transmission accuracy, and the viscosity temperature performance of the oil is also required. And shear stability should meet the various needs of different applications. There are many types of hydraulic oils, and the classification methods are different. For a long time, it is customary to classify by use, and also according to oil type, chemical composition or flammability. These classification methods only reflect the profitability of oil products, but they lack systemicity and it is difficult to understand the interrelationship and development of oil products.
