Features of hydraulic oils. How to choose them correctly?

Currently, there are quite a lot of hydraulic systems on the market. They can differ in size and hydraulic characteristics, purpose. But there are elements that become common to all devices. In addition, they all require, for example, competent and timely maintenance. Different brands of hydraulic oils help in solving this problem.

What should I pay attention to in the first queue?

The documentation of hydraulic system manufacturers usually specifies the requirements that a particular composition must meet. Do not try to improve the oil, thus violating the basic rules.

Many buyers believe that the best substances are those that are characterized by a large number of additives. But this is only an assumption, which only partly corresponds to reality. Additives are created in order to improve the specific characteristics of hydraulic oils. But the improvement of one parameter may adversely affect the other properties of a given material. In addition, we must remember that such substances are created immediately for a specific type of equipment. Therefore, it is necessary to look at how much oil is suitable for various operating conditions.

Additional property information

Classifications of the quality of hydraulic oils at the international level there are several. But quite often it happens that manufacturers of equipment themselves expose the requirements for the compositions that can be used for work. Usually this is due to the design features of any system. In addition, developers know how important it is to ensure compatibility of all components in the system with each other in order to organize high-quality uninterrupted work.

Loads on gaskets in such cases are increased, because oil works under Great pressure. During operation, the composition may lose its properties, so that from time to time it is required to change it. If you do not do it on time, then further repairs can be very expensive. No brand hydraulic oil here will not help.

In addition, trouble can happen if the system is filled with a compound that is not even provided by the manufacturer. So their recommendations really should be heeded.

Additional information about the properties of oils

To choose the right oil, you need to understand at what temperature it will be

To be operated. For example, there are winter and summer options. To select a hydraulic oil, the characteristics of which may be different, it is necessary to take into account its viscosity.

The operating temperature range in the system is what helps to determine the viscosity. In the operating instructions you can always find information that relates to certain characteristics. Some think that the pump also determines the viscosity of these compounds. But this is just a delusion, although quite common. The oil should have similar parameters simply to pass even to the narrowest places of the unit. The viscosity of the hydraulic oil must be such that it flows through the narrowest channels at a certain rate. Otherwise, the system may not work correctly.
