Introduction of hydraulic fluid for cutting machine [Ponse cutting machine encyclopedia]
The hydraulic oil of the cutting machine is the hydraulic medium used by the hydraulic system of the liquid pressure energy. It plays the role of energy transfer, anti-wear, system lubrication, anticorrosion, rust prevention and cooling in the hydraulic system. For hydraulic oil, the fluid viscosity should be met at working temperature and starting temperature first, because the viscosity change of the lubricating oil is directly related to the hydraulic action, transfer efficiency and transmission precision, and the viscosity and shear stability of the oil should be required for various uses. There are many kinds of hydraulic oil and different classification methods. For a long time, they are classified by use and classified according to the types of oil, chemical components or combustibility. These classification methods only reflect the earning of oil products, but lack of systematicness, and it is difficult to understand the relationship and development of oil products.
