Problems solved by technology

At present, the most widely used hydraulic oil generally has a narrow temperature range and is only suitable for high or low temperature environments. This makes some equipment that operates in different temperature areas or operates in environments with large temperature differences need to be replaced frequently. The process of matching hydraulic oil at this working temperature is time-consuming and labor-intensive, and the equipment also needs to be shut down to change oil, resulting in a great waste of manpower and social resources

Abstract

The invention relates to fully-synthetic efficient multifunctional hydraulic oil. The fully-synthetic efficient multifunctional hydraulic oil comprises the following components: synthetic base oil, an extreme pressure anti-wear agent, a high-temperature antioxidant, a low-temperature antioxidant, an ash-free clean dispersing agent, a friction improving agent, a viscosity index improving agent, a pour point depressant and an antirust agent, wherein the synthetic base oil is a mixture of PAO4, PAO10 and diester. The fully-synthetic efficient multifunctional hydraulic oil provided by the above technical scheme is high in viscosity index, low in pour point, high in flash point and large in adaptable working temperature range, and can work stably under the conditions of high temperature and low temperature; meanwhile, the hydraulic oil has excellent wear resistance, corrosion resistance and foam resistance, reduces the maintenance cost of equipment and has longer oil change period when being compared with mineral oil hydraulic oil.

Description

technical field [0001] The invention relates to the field of hydraulic oil, in particular to a fully synthetic high-efficiency multifunctional hydraulic oil. Background technique [0002] Hydraulic oil is the hydraulic medium used in hydraulic systems that utilize liquid pressure energy. It plays the roles of energy transmission, anti-wear, system lubrication, anti-corrosion, anti-rust, cooling, etc. in the hydraulic system. Hydraulic oil is usually formulated from highly refined petroleum lubricating oil base oil or synthetic lubricating oil with anti-wear and antioxidant agents, and is widely used in machine tools, mining engineering machinery, agricultural machinery, transportation machinery, aerospace and other aspects. [0003] A large number of facts show that more than 70% of hydraulic failures are caused by working media. Therefore, the correct selection and use of hydraulic media is of great significance to improve the performance, reliability, safety and life cycle...
