Performance parameters of hydraulic pumps: When selecting a hydraulic pump, various performance parameters need to be considered, such as maximum working pressure, maximum flow rate, efficiency, displacement, and rotational speed. These parameters are chosen and matched based on specific application needs and system requirements.

The main components of a hydraulic pump include the pump body, drive mechanism, inlet and outlet valves, and hydraulic oil reservoir. The pump body, typically made of metal, houses a series of gears, blades, or pistons. The drive mechanism, which can be an electric motor, engine, or manual operating device, provides the mechanical power to drive the pump body. The inlet and outlet valves control the flow direction and pressure of the liquid. The hydraulic oil reservoir stores the hydraulic oil and is connected to the pump body through pipelines.
