The application of electronically controlled hydraulic station and the actual work of the scene of the system requirements are increasingly demanding, such as the requirement of high pressure, high flow direction of operation, electronically controlled hydraulic station of the working conditions with the pressure, flow rate changes and constantly changing, the common use of hydraulic oil performance requirements are relatively stable, can have a long service life, therefore, the high performance of the electronically controlled hydraulic station requirements first of all, the electronically controlled hydraulic station of the working conditions put forward a stringent Requirements, as follows:

First, the viscosity of the hydraulic oil: hydraulic oil in the movement process has a certain viscosity. This viscosity ensures that the oil continues to flow, ensuring the pressure and oil flow.

Second, the contraction capacity of the hydraulic fluid: in the study of the static characteristics of the hydraulic system, it is generally recognized that the hydraulic fluid is not shrinkable liquid. Therefore, the hydraulic system requires a small shrinkage capacity of the hydraulic fluid.

In addition, electronically controlled hydraulic station on the hydraulic oil rust and corrosion resistance: in the role of water and air, rust and corrosion will occur in the metal surface of the hydraulic components. The particles generated by corrosion will circulate into the hydraulic system, resulting in wear and tear of the moving surfaces, leading to hydraulic system failure. Therefore, hydraulic fluid is required to have strong anti-rust and anti-corrosion properties, so that the metal surface will not rust and corrosion. Hydraulic anti-foaming properties: the fluid contains a small amount of air, which will cause the fluid to produce bubbles and foam. These bubbles and foam will make the hydraulic system produce vibration and noise, and make the performance of the system drop sharply, so the hydraulic system needs to minimize the bubbles and foam produced by the hydraulic fluid to make them disappear quickly.

Hydraulic station on the anti-emulsification performance of hydraulic oil: As hydraulic oil will be mixed with a small amount of water when working, so the hydraulic oil is emulsified under high speed and violent agitation. Emulsification occurs in the fluid, precipitation occurs, or other deposits are generated, which is very detrimental to the hydraulic system. Therefore, the hydraulic oil should have anti-emulsification properties, and can simply separate the oil and water. Compatibility: hydraulic oil and seals or hose contact time is long, and seals and hoses are mostly made of rubber materials, so hydraulic oil and rubber materials are expected to have compatibility. That is to say, the hydraulic oil will not have a deteriorating effect on the seals and hoses, as far as possible, so that the seals and hoses are not deformed and do not deteriorate. Hydraulic combustion: hydraulic combustion point is high, volatility is small, has excellent anti-flammable performance, to ensure that the hydraulic system in high temperature conditions. The above is the electronically controlled hydraulic station unification manufacturers of some strict requirements for hydraulic oil.
