Preparation method of anti-wear hydraulic oil

Abstract

The invention discloses a preparation method of anti-wear hydraulic oil, wherein the preparation method comprises the following steps: (1) evaluating the comprehensive performance of various base oils, and selecting the base oil with high comprehensive performance and reasonable price; (2) measuring the oil-water separation property, the foam characteristic, the condensation point and the anti-rust property in the presence of water of the base oil; (3) modifying the base oil; (4) friction performance test: on a four-ball machine, testing the influence of nanoparticles and an extreme pressure anti-wear agent on the friction performance of the hydrogenated base oil, analyzing the microscopic surface morphology of wear scars and the types, valence states and contents of the surface elements of the wear scars by adopting an optical contourgraph and a photoelectron spectrometer, researching the friction mechanism of a lubricating additive, and finding out a proper proportioning scheme; and (5) developing the multi-stage anti-wear hydraulic oil. The comprehensive performance of the hydraulic oil is improved by compounding a plurality of functional additives and a small amount of auxiliary additives through an optimal proportioning scheme of a single-factor additive.

Description

technical field [0001] The invention relates to the field of electric power system and transformer oil treatment, in particular to a preparation method of anti-wear hydraulic oil. Background technique [0002] 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. The current hydraulic oil cannot fully meet the needs of hydraulic machinery. Therefore, it is necessary to develop a multi-stage anti-wear hydraulic oil with high comprehensive performance and reasonable price, so that it has good lubricating performance and oxidation stability, and prolongs the life of the hydraulic oil. The service life of hydraulic components; at the same time, the frequency of oil change is reduced, the working efficiency of hydraulic machinery is improved, an...

Problems solved by technology

The current hydraulic oil cannot fully meet the needs of hydraulic machinery. Therefore, it is necessary to develop a multi-stage anti-wear hydraulic oil with high comprehensive performance and reasonable price, so that it has good lubricating performance and oxidation stability, and prolongs the life of the hydraulic oil. The service life of hydraulic components; at the same time reduce the number of oil changes, improve the working efficiency of hydraulic machinery, and achieve the purpose of energy saving and environmental protection

The amount of hydraulic oil used in our country is relatively large. Importing more advanced multi-grade hydraulic oil from abroad will increase the cost of hydraulic machinery; however, multi-grade hydraulic oil in the domestic market is rare, and the price is expensive, so it cannot be used on a large scale.
