Drucköl

Drucköl is a German term that translates to "pressure oil" or "hydraulic oil" in English. It refers to a specialized fluid used in hydraulic systems to transmit power. These fluids are designed to be incompressible, allowing them to efficiently transfer force from a pump to actuators, such as cylinders or motors. Drucköl plays a critical role in a vast array of mechanical applications, from heavy machinery and industrial equipment to automotive braking systems and aircraft flight controls.

The primary functions of Drucköl include transmitting power, lubricating moving parts within the hydraulic system to reduce wear and tear, sealing clearances between components to prevent leakage, and dissipating heat generated during operation. The specific properties required of Drucköl vary depending on the application, but generally include good thermal stability, high viscosity index (meaning its viscosity changes little with temperature fluctuations), excellent lubricity, and resistance to oxidation and foaming. Common base stocks for Drucköl include mineral oils, synthetic esters, and polyalphaolefins (PAOs), with various additives incorporated to enhance specific performance characteristics. The selection of the correct Drucköl is crucial for the reliable and efficient operation of any hydraulic system.
