Composition of hydraulic system

A complete hydraulic system consists of five parts, namely power components, hydraulic actuators, control components, detection and auxiliary components and hydraulic fluid. The function of the power component is to convert the mechanical energy of the prime mover into the pressure energy of the liquid. It refers to the oil pump in the hydraulic system, which provides power to the entire hydraulic system. The function of actuators (such as hydraulic cylinders and hydraulic motors) is to convert the pressure energy of the liquid into mechanical energy and drive the load to perform linear reciprocating or rotary motion. Hydraulic control components (i.e. various hydraulic valves) control and regulate the pressure, flow and direction of liquid in the hydraulic system. Hydraulic auxiliary components include oil tanks, oil filters, coolers, heaters, accumulators, oil pipes and pipe joints, sealing rings, quick-change joints, high-pressure ball valves, hose assemblies, pressure measuring joints, pressure gauges, oil level gauges, oil thermometer, etc. Hydraulic oil is the working medium that transmits energy in the hydraulic system. There are several categories such as various mineral oils, emulsions and synthetic hydraulic oils.
