What part of the hydraulic system is made up of

- Jul 26, 2018 -

A complete hydraulic system consists of five parts, namely the power element, the actuator, the control element and the hydraulic fluid. 1. The function of the power component is to convert the mechanical energy of the prime mover into the pressure energy of the liquid, which refers to the oil pump in the hydraulic system, which provides power to the entire hydraulic system. The hydraulic pump is generally constructed in the form of a gear pump, a vane pump and a plunger pump. 2. The function of the actuator (such as hydraulic cylinder and hydraulic motor) is to convert the pressure energy of the liquid into mechanical energy, and drive the load to make a linear reciprocating motion or a rotary motion. 3. Control elements (ie various hydraulic valves) control and regulate the pressure, flow and direction of the liquid in the hydraulic system. Depending on the control function, hydraulic valves can be divided into pressure control valves, flow control valves and directional control valves. The pressure control valve is further divided into a flow valve (safety valve), a pressure reducing valve, a sequence valve, a pressure relay, etc.; the flow control valve includes a throttle valve, a regulating valve, a split flow collecting valve, etc.; the directional control valve includes a one-way valve, Hydraulic control check valve, shuttle valve, reversing valve, etc. According to different control methods, hydraulic valves can be divided into switch control valves, fixed value control valves and proportional control valves. 4. Auxiliary components include fuel tank, oil filter, oil pipe and pipe joint, sealing ring, pressure gauge, oil level oil temperature gauge, etc. 5. Hydraulic oil is the working medium for transferring energy in hydraulic system. There are various kinds of mineral oil, emulsion and synthetic hydraulic oil.
