Hydraulic element is the core component of a hydraulic system, consisting of five parts: power element, actuator element, control element, auxiliary element, and working medium. The power components convert mechanical energy into hydraulic energy through gear pumps, vane pumps, etc; The actuator utilizes hydraulic cylinders and motors to convert hydraulic energy into mechanical motion; Control components include directional control valves, pressure control valves, and flow control valves, which are used to regulate system parameters.
Auxiliary components include supporting facilities such as oil tanks, filters, oil pipes, and sealing devices, while hydraulic oil serves as an energy transfer medium.
According to the application field, it can be divided into three categories: industrial equipment hydraulic components, walking machinery hydraulic components, and aerospace and navigation hydraulic components. Among them, walking machinery hydraulic components need to withstand higher power density and instantaneous high-pressure impact. The machining accuracy of the core hydraulic valve reaches the micrometer level, involving 24 common types such as direct acting relief valves, pilot operated relief valves, manual directional valves, etc. Its performance directly affects the operability and stability of the equipment.
