What component of a hydraulic system converts mechanical energy into hydraulic energy?

The hydraulic pump is the component of a hydraulic system that converts mechanical energy into hydraulic energy. It serves a critical function by taking the mechanical input—usually from an electric motor or a gasoline engine—and using it to drive the pump mechanism. As the pump operates, it generates flow and pressure by moving hydraulic fluid through the system, thus creating hydraulic energy that can be used to perform work, such as lifting, pushing, or turning loads.

In contrast, a hydraulic motor would convert hydraulic energy back into mechanical energy to drive a load, while a hydraulic valve is used to control the flow and direction of the hydraulic fluid within the system. The hydraulic filter's role is to clean the hydraulic fluid by removing contaminants, ensuring that the system operates efficiently and reliably. Each of these components plays a distinct role, but only the hydraulic pump is responsible for the initial conversion of mechanical energy into hydraulic energy.
