hydraulinestettä

Hydraulinestettä, commonly known as hydraulic fluid, is a non-compressibility fluid that transfers power in hydraulic machinery. It is the lifeblood of systems that lift, move, and control heavy loads, such as excavators, cranes, and industrial presses. The primary function of hydraulic fluid is to transmit hydraulic energy from a power source, like a pump, to a hydraulic actuator, such as a cylinder or motor.

Hydraulic fluids are typically oil-based, but can also be water-based or synthetic. They are designed to have specific properties, including a high viscosity index to maintain consistent viscosity across a range of temperatures, good lubricity to reduce wear on moving parts, and resistance to oxidation and degradation. Additives are often incorporated to enhance these properties and provide additional benefits like rust and corrosion inhibition, anti-foaming, and extreme pressure protection.

The choice of hydraulic fluid depends on the specific application and operating conditions. Factors such as temperature, pressure, environmental considerations, and compatibility with system components are crucial. Using the wrong type of hydraulic fluid can lead to equipment malfunction, reduced efficiency, and premature wear. Regular monitoring and maintenance of hydraulic fluid levels and quality are essential for the reliable operation and longevity of hydraulic systems.
