Hydraulic Fluids
Hydraulic fluids are specialized liquids used in hydraulic systems to transmit power, dissipate heat, and lubricate components. These fluids are crucial for the efficient and reliable operation of hydraulic equipment in various industrial, agricultural, and mobile applications.
Physical and Chemical Properties
Hydraulic fluids exhibit several remarkable physical and chemical properties:
Viscosity: The viscosity of hydraulic fluids is critical for system performance and varies with temperature.
Lubricity: Hydraulic fluids provide excellent lubrication to minimize component wear.
Corrosion Protection: These fluids contain additives that improve corrosion resistance and extend the lifespan of hydraulic components.
Heat Resistance: Hydraulic fluids withstand high temperatures and help dissipate heat efficiently.
Oxidation Resistance: The fluids resist oxidation, preventing the formation of deposits and acids.
Water Resistance: Hydraulic fluids repel water and prevent emulsion formation, which could impair system performance.
Use of Hydraulic Fluids
Thanks to their unique properties, hydraulic fluids are widely used in many areas:
Industrial hydraulic systems: Used in machines and equipment for power transmission and motion control.
Mobile hydraulics: Used in construction and agricultural machinery such as excavators, tractors, and forklifts.
