During the use of hydraulic oil, even at normal temperature and pressure, it will gradually undergo oxidative decomposition, deterioration, discoloration, emulsification and acidification, which will not only reduce the hydraulic performance and lubrication performance, but also corrode parts, and precipitate and sludge generated by oxidative deterioration will also block pipelines, resulting in control failure and even serious accidents. Anti-wear hydraulic oil, the price is often higher than ordinary hydraulic oil, and its service life is much longer than ordinary hydraulic oil. Therefore, after selecting high-quality lubricating oil, giving full play to its quality advantages and reasonably prolonging the oil change cycle can prolong the maintenance cycle and service life of hydraulic system and even the whole equipment, and bring huge economic benefits to enterprises.
There are many factors that determine and affect the oil change cycle of hydraulic oil, which can be summarized as follows:
1. Quality factors of hydraulic oil itself
Hydraulic oil is generally composed of refined mineral oil, that is, base oil and several additives to improve performance. Both of them have great influence on the oil change cycle.
Mineral oil components are complex, and their oxidation stability is different, which leads to different service life. In addition, mineral oil also contains natural "antioxidant components", such as high molecular weight sulfur-containing polycyclic compounds, and "oxidation-promoting components", such as water, oxygenated hydrocarbons and some metal compounds. When there are more antioxidant components than pro-oxidant components, the oxidation speed of base oil is slow and the service life is long, whereas the oxidation speed is fast and the service life is short. The composition structure of mineral oil is greatly influenced by the composition of crude oil, but ultimately depends on refining technology and refining depth. Therefore, the choice of base oil not only affects the service performance of hydraulic oil, but also affects its service life. ?
additives are the essence of hydraulic oil, which can greatly improve various performance indexes of hydraulic oil. Among them, antioxidants can passivate the pro-oxidation components in hydraulic oil and interrupt the oxidation chain reaction, thus greatly improving the anti-oxidation stability of hydraulic oil and prolonging the service life of hydraulic oil. Because high-quality hydraulic oil contains many additives, its performance is much higher than that of ordinary hydraulic oil, and its service life is naturally much longer than that of ordinary hydraulic oil. Especially, the antiwear hydraulic oil contains additives such as antioxidant, emulsion, rust inhibitor and antifoaming agent, and also contains extreme pressure antiwear agent, which helps to reduce the wear of hydraulic pump and hydraulic system and prolong the service life of hydraulic system, and also helps to prolong the service life of hydraulic oil because of reducing endogenous pollution.
Texaco anti-wear hydraulic oil is carefully formulated with high-quality paraffin-based mineral oil as base oil and additives with excellent performance. The patented technology of special effect anti-sludge formation makes it have extraordinary cleaning effect and provides a long service life, and is praised as a cleaning expert by the industry. It combines the wear resistance of gear oil, the long life of circulating oil and the stability of hydraulic oil, and its service life is obviously longer than that of ordinary hydraulic oil, which meets the quality requirements of major hydraulic equipment manufacturers all over the world.
2. Factors of working conditions
The working conditions of hydraulic oil also have a great influence on its service life. Such as high load, high speed, high pressure, high dust, high temperature and high cycle strength, on the one hand, it intensifies the intensity and frequency of surface contact and wear of machine parts and intensifies the tribochemical reaction, on the other hand, it increases the temperature of hydraulic oil, accelerates the oxidative decomposition of hydraulic oil and promotes the generation of aldehydes, ketones, acids and even sludge. Especially when the oil temperature exceeds 125℃, the oxidation deterioration speed of hydraulic oil will be accelerated sharply, thus greatly shortening the oil change cycle of hydraulic oil.
Texaco anti-wear hydraulic oil is formulated with special extreme pressure anti-wear additive, and its anti-wear performance is comparable to that of heavy-duty gear oil, reaching the highest level of FZG12. Under the condition of stamping load, it can effectively control the wear of parts and prolong the service life of equipment. High-quality base oil and special anti-oxidation formula make Amway anti-wear hydraulic oil have high oxidation stability, and oil scale will not appear when it runs under heavy load or high temperature for a long time. So as to prevent the filter from being blocked, and better protect the system clean, smooth and good operation.
3. Human factors
are mainly maintenance factors, which will also affect the oil change cycle of hydraulic oil. Improper use and maintenance will greatly shorten the service life of hydraulic oil, such as not checking the oil level on time to replenish new oil, not cleaning and replacing the filter element on time and not paying attention to keeping the hydraulic system clean.
