Hydrauliöljyissä

Hydrauliöljyissä, known in English as hydraulic oil, are specialized fluids used in hydraulic systems to transmit power. These oils are designed to lubricate moving parts, dissipate heat, prevent corrosion, and seal clearances within the hydraulic system. The primary function of hydraulic oil is to transfer energy from a pump to an actuator, such as a hydraulic cylinder or motor, enabling the operation of heavy machinery, vehicles, and industrial equipment.

The composition of hydraulic oil varies, but common base stocks include mineral oils, synthetic oils, and vegetable oils. Additives are crucial components that enhance the oil's performance. These additives can include anti-wear agents, antioxidants, corrosion inhibitors, viscosity modifiers, and defoamers. The choice of hydraulic oil depends on the specific operating conditions, temperature range, pressure requirements, and environmental considerations of the hydraulic system.

Proper maintenance of hydraulic oil is essential for the longevity and efficiency of hydraulic systems. Regular checks of oil level, cleanliness, and viscosity are recommended. Contamination, such as water or particulate matter, can degrade the oil's properties and lead to system damage. Filtration systems are often employed to maintain oil purity. The disposal of used hydraulic oil must also be handled responsibly due to its potential environmental impact.
