Problems solved by technology

[0004] With the development and wide-scale use of hydraulic machinery, as well as the development of human beings in areas with harsh environments, the hydraulic system will face more tests from the working environment, so the hydraulic system has higher and higher requirements for hydraulic oil. Oil can not fully meet the needs of hydraulic machinery, so it is necessary to develop a hydraulic oil with high comprehensive performance and reasonable price to improve the deficiencies of the existing technology, thereby improving the working efficiency of hydraulic machinery

Abstract

The invention provides a method of preparing hydraulic oil for mechanical equipment. The method comprises the preparing steps that firstly, nanometer bentonite powder, 32N third class hydrogenation base oil, 32NS third class hydrogenation base oil, phthalic acid dioctyl ester and poly alpha-olefin synthetic oil are added into a reaction kettle, and after uniform stirring, a first mixture is obtained; secondly, a viscosity modifier, an extrusion anti-wear agent, an antioxidant and a metal deactivation agent are added in the first mixture in sequence and mixed uniformly, after stirring, a second mixture is obtained; thirdly, a lubricant is added into the second mixture, and after stirring, a third mixture is obtained; fourthly, an anti-foaming agent is added into the third mixture, and after stirring and filtering, the hydraulic oil for the mechanical equipment is prepared. The prepared hydraulic oil has good abrasion resistance, wetting property and oxidation stability performance, the service life of the hydraulic oil and hydraulic components is prolonged, and the working efficiency of the hydraulic machinery is improved.

Description

technical field [0001] The invention belongs to the technical field of mechanical lubricating oil, and in particular relates to a preparation method of hydraulic oil used for mechanical equipment. Background technique [0002] Hydraulic oil is an important part of hydraulic technology. In the hydraulic system, it can play the role of energy transmission, system lubrication, anti-corrosion, anti-rust, cooling and so on. With the continuous development of hydraulic system technology, the application of precision components is becoming more and more extensive, such as precision filters, etc. In order to ensure the smooth operation of precision instruments, the quality requirements of hydraulic system oil are gradually increasing. It is required that the hydraulic oil should have good viscosity-temperature properties, anti-wear properties, hydrolytic stability, and the adaptability and filterability of related materials, especially thermal stability and oxidation stability, so a...
