Fluid power systems use liquids or gases to transmit and control energy. These systems typically consist of components like pumps, valves, and actuators that work together to perform tasks such as lifting, moving, or controlling machinery. Common applications include construction equipment, manufacturing machinery, and automotive systems. There are two main types of fluid power systems: hydraulic systems, which use liquids, and pneumatic systems, which use gases. Hydraulic systems are known for their high power density and ability to handle heavy loads, while pneumatic systems are often used for lighter tasks and provide quick, responsive movements.
