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.
