The scope of application of hydraulic accessories is very wide, because hydraulic components include hydraulic pumps, hydraulic motors, hydraulic valves, hydraulic cylinders, etc., and hydraulic valves include pressure control valves, flow control valves, and directional control valves.  sae standard parts .It can be divided into plate valve, tube valve, proportional valve, servo valve and so on. The specific functions of hydraulic accessories are as follows:
The hydraulic system is mainly composed of five parts: power components (oil pump), executive components (cylinders or hydraulic motors), control components (various valves), auxiliary components and working medium.
1. The power element (oil pump) is used to convert the mechanical energy of the prime mover into hydraulic energy; it is the power part of the hydraulic transmission.
2. The actuator (cylinder, hydraulic motor) converts the hydraulic energy of the liquid into mechanical energy. Among them, the cylinder moves in a straight line and the motor moves in a rotary motion.
3. The control components include pressure valves, flow valves and directional valves. Their function is to steplessly adjust the speed of the hydraulic motor according to the needs, and to adjust and control the pressure, flow and flow direction of the working fluid in the hydraulic system.
4. Auxiliary components other than the above three parts, including pressure gauges, oil filters, energy storage devices, coolers, pipe fittings {mainly include: various pipe joints (flared, welded, ferrule, sae Flanges), high-pressure ball valves, quick-change joints, hose assemblies, pressure measuring joints, pipe clamps, etc., and fuel tanks are also very important.
5. Working medium refers to the hydraulic oil or emulsion in various hydraulic transmissions, which realize energy conversion through oil pump and hydraulic motor.
In short, hydraulic fittings are widely used in construction machinery, mining, metallurgy, construction, and aerospace.
