Hydraulic system mainly consists of five parts:
1, energy device-energy device is supply hydraulic system pressure oil, put the mechanical energy conversion to the pressure of fluid can device. One of the most common form is hydraulic pump; If is the pneumatic system, energy device is air compressor. Also is a power parts.
2, actuators, actuators is the pressure of liquid can convert into mechanical device. The form has linear motion of hydraulic cylinder, turn the hydraulic motor sports do. They also called the execution element of hydraulic system. 3, control adjusting device-control adjusting device for hydraulic system is the liquid pressure, flow and flow direction control and adjust the device such as a relief valve, throttle valve, reversing valves, open stop valves, etc.
4, auxiliary devices part-in addition to the above device other than the device, such as oil tank, filters, accumulator, etc, tubing, etc. They work to ensure that the system is indispensable.
5, working medium-work medium is to transfer energy fluid, such as hydraulic oil, water-glycol, air, etc.
