Theory
1. Hydraulic fluid: Hydraulic systems use specific hydraulic fluid (usually hydraulic oil) as the energy transfer medium. Hydraulic fluid flows through the system and transfers force and energy through pressure.
2. Hydraulic pump: The hydraulic pump is the power source of the hydraulic system. It converts mechanical energy into hydraulic energy through mechanical means. Hydraulic pumps create high-pressure fluid, pushing it through the system.
3. Hydraulic cylinder: Hydraulic cylinder is an actuator in a hydraulic system and is used to generate force and movement. A hydraulic cylinder consists of a sleeve and a piston. When hydraulic fluid enters the cylinder, the hydraulic pressure causes the piston to be forced and move along the axis of the cylinder.
4. Hydraulic valve: Hydraulic valves are used to control the flow and pressure of liquids in hydraulic systems. They can open or close flow paths, regulate flow and pressure, and perform other control functions. Common hydraulic valve types include relief valves, directional control valves, proportional valves, etc.
5. Hydraulic lines: Hydraulic lines are used to transfer hydraulic fluid from one component to another. Hydraulic pipelines are composed of various pipes, joints, elbows and connectors to ensure the flow and transfer of liquids.
6. Hydraulic oil reservoir: The hydraulic oil reservoir is used to store hydraulic fluid in the hydraulic system and balance pressure fluctuations in the system. They also absorb shock and vibration in the system.
The working principle of hydraulic accessories is to convert hydraulic energy into mechanical energy and transmit force and action through the pressure of the liquid. Through reasonable configuration and control of hydraulic accessories, various appliions can be realized, such as motion control and force transmission in engineering machinery, machine tools, aerospace and other fields.
