The driving force element (oil pump), the execution element (oil cylinder or oil motor), the operating element (various valves), the auxiliary element and the working medium are composed of five parts.

1. The driving force element (oil pump) has the effect of converting the chemical energy of the liquid transmission device into liquid working pressure energy; it is a part of the energy in the hydraulic transmission system.

2. Execution element (oil cylinder. Oil motor) It converts the hydraulic energy of the solution into mechanical kinetic energy. Among them, the oil cylinder of the double ferrule type joint manufacturer does a uniform linear motion, and the motor does a rotating fitness exercise.

3. Control elements include pressure valve, flow valve and angle valve, etc. Their effect is to control the speed of the hydraulic drive according to the frequency conversion, and to adjust the working pressure, total flow and inflow of the working solution in the hydraulic system.

4. Auxiliary components other than the above three parts, including barometer, oil filter, energy storage device, cooling tower, pipe {key includes: various tee joints (flare type, welding, card) sleeve type, sae flange), electric ball valve, quick connector, plastic hose assembly, pressure measuring joint, spring hanger, etc.} and oil tank, etc., they are also very important.

5. Working medium Working medium refers to gear oil or emulsified oil in various hydraulic transmission systems, which completes heat transfer through oil pump and hydraulic power. The hydraulic system is to complete the active power transmission according to the medium. The protection steel wire will not be corroded, and the outer rubber layer will not be damaged.
