What is included in a complete hydraulic system?
Jan 15,2024
A complete hydraulic system consists of five parts, namely, power components, the implementation of components, control components, auxiliary components and hydraulic medium. The function of the power element 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 structure of the hydraulic pump is generally gear pump, vane pump and plunger pump. The role of the implementation of components (such as hydraulic cylinders and hydraulic motors) is to convert the pressure energy of the liquid into mechanical energy to drive the load for linear reciprocating motion or rotary motion. Control elements (I. e., various hydraulic valves) control and regulate the pressure, flow and direction of the fluid in the hydraulic system. According to the different control functions, hydraulic valves can be divided into pressure control valves, flow control valves and directional control valves. Pressure control valve is divided into relief valve (safety valve), pressure reducing valve, sequence valve, pressure relay, etc.; flow control valve including throttle valve, regulating valve, shunt collecting valve, etc.; direction control valve including one-way valve, hydraulic control 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. Auxiliary components include oil tank, oil filter, oil pipe and pipe joint, sealing ring, pressure gauge, oil level oil temperature gauge, etc. Hydraulic oil is the working medium to transfer energy in the hydraulic system. There are various types of mineral oil, emulsion and synthetic hydraulic oil.
