The principle of hydraulic system
What's your system? The hydraulic system is a lot of you ask too general the hydraulic system is nothing but the ability transformation, you specifically ask what hydraulic device is I good to give you say
The basic principle of the hydraulic system is that the internal pressure of the liquid is the same everywhere. Using a certain internal pressure caused by the oil pump of liquid oil, hydraulic actuators via hydraulic line, such as hydraulic oil cylinder, high pressure oil effect on the piston, the unbalanced pressure on both ends of the piston, and the piston movement work, high pressure oil can also effect on with blade, blade shaft rotates, this is the oil motor. Hydraulic system is a device which transmits the pressure, the hydraulic oil is the carrier of the pressure transmission, has a certain pressure of liquid effect in a certain area and the size of forces, the forces driving parts movement.
Also known as positive displacement hydraulic transmission, hydraulic transmission is to use liquid as the medium, liquid pressure energy and kinetic energy is used to transfer energy transmission and control. Usually used his remaining liquid pressure to the hydraulic system of the use of liquid medium called the hydraulic oil. Hydraulic transmission, small volume, light weight, compact structure, easy for stepless speed regulation and standardize and systematize, generalizing. So widely used in metallurgical machinery, engineering machinery, mining machinery, agricultural machinery, automobiles, ships, aircraft, etc. The hydraulic system although varied, but from the point of view of energy conversion, the working principle and composition of basically the same. Typical hydraulic system includes a hydraulic pump, hydraulic oil tank, directional control valve, flow control valve, working cylinder, plunger valve and relief valve. Hydraulic system that is commonly used in three kinds of typical hydraulic pump for the gear pump, vane pump and axial pump. Power element pump is the heart of the liquid system. Hydraulic pump control components (including flow valve, relief valve, direction valve, proportional valve, etc.) is used to control and regulate the flow of fluid pressure. Traffic and direction, in order to meet the requirements of equipment performance, and achieve a variety of different work cycle, the components of the liquid pressure can be transformed into mechanical energy, which drives the mechanism motion.
