Hüdraulikavedelik

Hüdraulikavedelik is a term used in Estonian to refer to hydraulic fluid. Hydraulic fluid is a non-compressible medium used in hydraulic systems to transmit power. Its primary function is to transfer energy from a power source, such as a pump, to an actuator, such as a cylinder or motor.

The properties of hydraulic fluid are crucial for the efficient and safe operation of a hydraulic system. Key properties include viscosity, which affects the fluid's flow characteristics and its ability to lubricate; thermal stability, which determines its resistance to breakdown at high temperatures; oxidative stability, which prevents degradation due to contact with oxygen; and lubricity, which reduces friction and wear between moving parts.

Hydraulic fluids are typically petroleum-based, but synthetic and water-based fluids are also used depending on the application. Additives are often incorporated into hydraulic fluids to enhance their performance, such as anti-wear agents, corrosion inhibitors, and demulsifiers to separate water.

Contamination is a major concern for hydraulic systems. Particles, water, and air can degrade the fluid and damage system components. Therefore, proper filtration and maintenance of the hydraulic fluid are essential. Regular testing of the fluid's condition can help predict potential problems and ensure the longevity of the hydraulic system.
