1. 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.
2. The role of the hydraulic control system
The role of the hydraulic control system is to convert the input mechanical or electrical energy into hydraulic energy, and through the control of the flow and pressure of the liquid, to realize the control of the force and movement of the executive element. Its main role includes the following aspects:
① Provide a large amount of power and torque. The hydraulic system can provide a large amount of power and torque by increasing the pressure and flow, so as to meet a variety of high loads and high power requirements; ② Realize high-precision motion control: The hydraulic system can realize high-precision motion control, such as position, speed, acceleration, etc., by controlling the flow and pressure. ③Provide a reliable power source:The hydraulic system has high reliability and stability, can be operated for a long time under the harsh working environment, and is easy to maintain and repair.④Improve work efficiency:Hydraulic system is characterized by fast response and high-speed movement, which can improve work efficiency and productivity.
Nowadays, hydraulic control system is widely used in various industrial fields, such as machine tools, metallurgy, mining, construction, aviation, aerospace, military and so on. It has the advantages of stable transmission, large power output, fast response speed, high control accuracy, etc. It has become an important part of modern industrial automation. Hydraulic control system has the advantages of large power output, high reliability, low noise, small size, light weight, high efficiency and energy saving.
