What are the functions of hydraulic components

The hydraulic system mainly consists of five parts: power components (oil pump), execution components (oil cylinder or hydraulic motor), control components (various valves), auxiliary components, and working medium. 1. The function of the power component (oil pump) is to convert the mechanical energy of the prime mover into hydraulic pressure energy; It is the power part of hydraulic transmission. 2. Execution components (cylinders, hydraulic motors) convert hydraulic energy of liquids into mechanical energy. Among them, the oil cylinder performs linear motion and the motor performs rotational motion. 3. Control components include pressure valves, flow valves, and directional valves. Their function is to continuously adjust the speed of the hydraulic motor as needed, and to regulate and control the pressure, flow rate, and direction of the working fluid in the hydraulic system. 4. In addition to the above three parts, auxiliary components include pressure gauges, oil filters, energy storage devices, coolers, pipe fittings (mainly including various pipe joints (expansion type, welding type, sleeve type, SAE flange), high-pressure ball valves, quick change joints, hose assemblies, pressure measuring joints, pipe clamps, etc.) and oil tanks, which are equally important. 5. The working medium refers to hydraulic oil or emulsion in various hydraulic transmissions, which is converted into energy through oil pumps and hydraulic motors.
