Technical information

Hydraulic oils are liquids that have been produced and developed for power transmission systems and have been added with additives according to their structure.

In order to select the appropriate oil according to the system used, it is necessary to know the main functions of hydraulic oils, and accordingly, properties such as compressibility and power transmission, air removal, foaming, viscosity, pour point should be considered. It should be known how anti-corrosion, water-removing additives work. In addition, ISO viscosity classes, the selection of viscosity according to the equipment, the use of the viscosity selection table and the features that the hydraulic oils should have in accordance with environmental and occupational safety are also of great importance. Hydraulic systems find a wide area of ​​use due to their advantages.

Important Applications Are:

• In production applications; Presses, heavy machinery, robots, plastic injection machines.
• Raw Material Industries; Mining industry, bridge control mechanisms, dams.
• Mobile Equipment; Excavators and cranes, construction equipment, long haul vehicles, agricultural machinery, aircraft, ships.
• Duties of Hydraulic Oils:
• The most important functions of hydraulic oils;
• Incompressibility: Thus, the pressure, and thus the power, reaches the desired location efficiently and instantly.
• Air-tightness: Air bubbles that may mix into the liquid must be separated from the oil very quickly in order not to impair its incompressibility.
• Non-foaming feature: There should be no foam in the hydraulic system.
• Appropriate viscosity: It should be able to flow easily, and it should be able to lubricate without leaking and escaping from the system.

The most popular and widely used hydraulic oil manufacturers are as follows;

• Shell Hydraulic Oils
• Mobil Hydraulic Oils
• Petrol Ofisi Hydraulic Oils
