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. They are widely used in industries like construction, manufacturing, and automotive. The two main types of fluid power systems are hydraulic systems, which use liquids, and pneumatic systems, which use gases. Hydraulic systems are known for their high power and efficiency, while pneumatic systems are often preferred for lighter tasks due to their speed and simplicity.
