Hydraulvätska

Hydraulvätska, often called hydraulic fluid, is a non-compressible fluid used in hydraulic systems to transmit power. These systems are found in a wide variety of applications, from heavy machinery like excavators and cranes to automotive brakes and power steering. The primary function of hydraulvätska is to transfer the force applied to a fluid under pressure to another part of the machine, enabling it to perform work.

The properties of hydraulvätska are crucial for the efficient and safe operation of hydraulic systems. It must possess good lubricity to reduce wear on moving parts, thermal stability to withstand varying operating temperatures without degrading, and resistance to oxidation and corrosion to prevent system damage. It also needs to be relatively incompressible to ensure a responsive and precise transfer of power. Common types of hydraulvätska include mineral oil-based fluids, synthetic fluids, and water-glycol mixtures, each chosen based on the specific requirements of the application, such as operating temperature, pressure, and environmental considerations.

Contamination is a major concern for hydraulic systems, as dirt, water, or air can compromise the fluid's performance and lead to premature component failure. Therefore, proper maintenance, including regular fluid analysis and filtration, is essential to extend the life of both the hydraulvätska and the hydraulic system itself. The selection and maintenance of the correct hydraulvätska are fundamental to the reliability and longevity of any hydraulic equipment.
