A kind of preparation method of anti-wear hydraulic oil

Abstract

The invention discloses a preparation method of anti-wear hydraulic oil, comprising the following steps: (1) evaluating the comprehensive performance of various base oils, and selecting a base oil with high comprehensive performance and reasonable price; (2) evaluating the comprehensive performance of the base oil Oil-water separability, foam characteristics, freezing point, anti-rust performance in the presence of water were measured; (3) Modification of base oil; (4) Friction performance test: On a four-ball machine, test the effect of nanoparticles and extreme pressure anti-wear agent on the The influence of hydrogenated base oil on the friction properties, and the use of optical profilometer and photoelectron spectrometer to analyze the wear scar microscopic surface morphology and the type, valence and content of elements on the wear scar surface, to study the friction mechanism of lubricating additives, and to find suitable (5) Development of multi-stage anti-wear hydraulic oil. The invention improves the comprehensive performance of the hydraulic oil by compounding a variety of functional additives and a small amount of auxiliary additives through the optimal proportioning scheme of the single factor additive.

Description

technical field [0001] The invention relates to the field of processing power system and transformer oil, 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 challenges from the working environment, so the hydraulic system's requirements for hydraulic oil are getting higher and higher. The current hydraulic oil can not fully meet the needs of hydraulic machinery, so 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 hydraulic oil and The service life of hydraulic components; at the same time, the number of oil changes is reduced, the working efficiency of hydraulic machinery is improved, and the purpose...

AI Technical Summary

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.
