The composition of the hydraulic control system

Hydraulic control system is usually composed of the following components

Hydraulic energy device: to provide liquid pressure, common energy devices such as hydraulic pumps and pressure tanks.

Hydraulic actuator: the implementation of the task, including hydraulic cylinders, hydraulic motors, hydraulic valves and so on.

Hydraulic transmission piping: the liquid transmission to the executive element, including pressure piping, tubing, connectors and so on.

Hydraulic control components: used to control the flow of liquid and pressure, including pressure control valves, flow control valves, directional control valves.

Electrical control components: used to control the hydraulic system start, stop, steering and speed, including switches, electrical controllers, solenoid valves, etc.

The components of the hydraulic control system can be combined and adjusted according to specific applications and requirements to meet a variety of different engineering needs.
