Description
Technical Field
The invention relates to the field of hydraulic oil, in particular to high-pressure anti-wear hydraulic oil.
Background
As the pressure of hydraulic equipment increases, speed increases and compactness, higher demands are placed on hydraulic oil. The hydraulic oil is a hydraulic medium used by a hydraulic system utilizing hydraulic pressure energy, and plays roles of energy transfer, system lubrication, corrosion prevention, rust prevention, cooling and the like in the hydraulic system.
At present, the common anti-wear hydraulic oil is divided into two types according to the base oil content, namely HM, HR and HV of refined mineral base oil and HS of synthetic base oil; according to the additive types, the additive comprises a zinc type formula which takes ZDDP as a main agent and an ashless formula which takes sulfur, phosphorus and nitrogen agents as main agents; the anti-wear hydraulic oil and the high-viscosity index anti-wear hydraulic oil are divided according to the viscosity index. The zinc-containing anti-wear hydraulic oil can easily pass through a vane pump, but is difficult to pass through a plunger pump, because the ZDDP in the formula severely corrodes copper-plated parts of high-pressure plungers in use, so that the hydraulic pump is damaged, and after a small amount of water is mixed in the oil, severe emulsification is generated, so that the blockage of a filter system is caused.
At present, zinc-free antiwear hydraulic oil is a branch of hydraulic oil and has properties which are not possessed by many zinc-containing antiwear hydraulic oils. The prepared zinc-free antiwear hydraulic oil only adopts an ashless extreme pressure antiwear agent. The selection of the ashless extreme pressure antiwear agent mainly has two problems, namely hydrolytic stability and extreme pressure antiwear property. A good extreme pressure antiwear agent not only needs to have certain extreme pressure property and good antiwear property, but also needs to have good hydrolytic stability and thermal stability. The traditional single ashless extreme pressure antiwear agent is difficult to meet the requirements of oil performance, and a plurality of extreme pressure antiwear agents are required to be compounded for use.
