As a core power component in hydraulic systems, the hydraulic pump is driven by an engine or electric motor. It draws hydraulic oil from the oil tank, generates pressurized oil, and delivers it to the actuator.
Structurally, hydraulic pumps fall into three main categories: piston pumps (plunger pumps), vane pumps, and gear pumps.
The hydraulic motor acts as a critical actuator in hydraulic systems, tasked with transforming hydraulic pressure energy from the hydraulic pump into usable mechanical energy, manifesting as torque and rotational speed on its output shaft.
Main types of hydraulic motors include: piston motors, vane motors, gear motors, and orbit motors.
The hydraulic valve serves as a vital regulatory component in hydraulic transmission, playing a key role in controlling the pressure, flow rate, and direction of hydraulic fluid to ensure stable system operation.
According to their functions, hydraulic valves are classified into three main types: pressure control valves for pressure management, flow control valves for flow rate adjustment, and directional control valves for controlling fluid on-off and flow direction.
In addition to the three key hydraulic components—hydraulic pumps, hydraulic motors and hydraulic valves—we also supply a full suite of supporting elements including hydraulic cylinders, accumulators and filters to meet complete system requirements.
