Definition

Noun: A hydraulic system is a mechanism that operates by using the force generated when a liquid is pushed through a confined space, such as a small opening or tube. It functions based on the principles of fluid power, where pressure transmitted by the liquid is used to create motion or perform work.

Usage

A hydraulic system is used to transfer power and control machinery by utilizing pressurized fluid. It is a core component in many types of equipment. * The excavator's arm is powered by a complex hydraulic system. * Aircraft rely on a hydraulic system to operate their landing gear and flight control surfaces. * Maintaining the correct fluid level is crucial for the hydraulic system to function properly.

Advanced Usage

• "to actuate a hydraulic system": To cause the system to start operating or to set its components in motion.
  • The pilot actuated the hydraulic system to lower the flaps.
• "a failure in the hydraulic system": A malfunction or breakdown within the system's components.
  • The machine was shut down due to a catastrophic failure in the hydraulic system.

Variants and Related Words

• Hydraulics (n): The branch of science and engineering concerned with the mechanical properties and use of liquids. It also refers to the system itself in a more technical context.
  • He studied fluid dynamics and hydraulics in university.
• Hydraulic (adj): Pertaining to water or other liquids in motion, or operated by liquid pressure.
  • The car uses hydraulic brakes.

Synonyms

• Fluid power system: A more general term for systems using pressurized fluid (liquid or gas) to generate power.
• Hydrostatic drive: A specific type of hydraulic system used for propulsion, often in heavy machinery.

Related Phrases

• Hydraulic fluid: The special liquid used within a hydraulic system to transmit power.
  • The mechanic checked the level and quality of the hydraulic fluid.
• Hydraulic pressure: The force per unit area exerted by the fluid within the system.
  • The gauge shows the hydraulic pressure is within normal operating range.

Noun

1. a mechanism operated by the resistance offered or the pressure transmitted when a liquid is forced through a small opening or tube
