Knowra Hydraulic fluid Hydraulic fluid Hydraulic fluid transmits power through pressurized liquid in machinery. It also lubricates moving parts, carries heat, and protects components from corrosion and wear.
Pascal's law : Pressure applied to a confined fluid is transmitted throughout the fluid and to the container walls. It explains how pressure in hydraulic fluid transfers force through a circuit.
Viscosity : A fluid's resistance to flow, arising from internal friction. It governs leakage, lubrication, and energy loss as hydraulic fluid moves.
Aircraft hydraulic system : An aircraft system that uses pressurized fluid to operate controls, landing gear, brakes, or other equipment. Aircraft systems demand fluids suited to wide temperature ranges and stringent reliability requirements.
Pneumatic system : A system that uses compressed gas to transmit and control power. It uses compressible gas rather than liquid, producing different stiffness and response.
Hydraulic fluid contamination : The presence of unwanted particles, water, air, or chemicals in hydraulic fluid. Contamination can abrade components, obstruct valves, and accelerate fluid degradation.
Hydraulic pump : A machine that converts mechanical energy into hydraulic energy by moving fluid through a system. It supplies the flow that pressurizes hydraulic fluid in many circuits.
Viscosity index : A measure of how strongly a liquid's viscosity changes with temperature. A high index helps hydraulic fluid retain useful viscosity across temperature changes.
Automotive brake fluid : A specialized hydraulic fluid that transmits force in vehicle braking systems. It is a prominent hydraulic-fluid application with demanding boiling-point and moisture-control requirements.
Mechanical transmission : A system of components that transfers mechanical power between a source and a load. It transfers power through solid mechanisms instead of pressurized hydraulic fluid.
Hydraulic filter : A component that removes contaminants from hydraulic fluid as it circulates. Filtration controls particle contamination and helps protect close-tolerance components.
