What is a hydraulic system?
A complete hydraulic system consists of five parts: the power component, the execution element, the control element, the non-piece and the hydraulic oil. The power element is used to convert the mechanical energy of the original motive into the liquid pressure energy, which is the oil pump in the hydraulic system, which provides the power to the whole hydraulic system. The hydraulic pump is structured in the form of gear pumps, vane pumps and plunger pumps. The function of the actuator, such as a hydraulic cylinder and hydraulic motor, is to convert the pressure of the liquid to the mechanical energy, and the driving load as a straight and reciprocating motion. The control element (i.e., various hydraulic valves) controls and regulates the pressure, flow and direction of the fluid in the hydraulic system. According to the control function, the hydraulic valve can be divided into the village force control valve, the flow control valve and the directional control valve. The pressure control valve is divided into the benefit flow valve (relief valve), pressure relief valve, sequence valve, pressure relay, etc. Flow control valves include throttle valves, adjustment valves, and diverter collector valves; Directional control valves consist of one-way valve, liquid control one-way valve, shuttle valve, reversing valve, etc. According to the control mode, the hydraulic valve can be divided into switch control valve, fixed value control valve and proportional control valve. The auxiliary elements include the oil tank, oil filter, tubing and pipe joint, sealing ring, pressure gauge, oil level oil temperature meter, etc. Hydraulic oil is the medium of the energy transfer energy in hydraulic system, there are various kinds of mineral oil, emulsified liquid and hydraulic oil
Can deliver "size are the same in all directions from a liquid. The piston of the pressure is also equal to P. If the cross-sectional area of the piston is S2, pressure P on the large piston upward pressure generated by the F2 = PxS2 The sectional area is a multiple of the cross-sectional area of the small piston. From the type, add a small force on the small piston, has got a lot of force on the piston, for this hydraulic press is used to suppress plywood, oil, extract weight, forging steel, etc.

The principle of hydraulic It is composed of two tanks of different sizes filled with water or oil. Water is called "hydraulic press"; Oil filling is called "hydraulic press". Two has a sliding in each cylinder piston, if a certain value of pressure on small piston, according to PASCAL's law, the piston to the pressure by the pressure of the liquid is passed to the piston, the piston top. The cross-sectional area of the small piston is S1, and the downward pressure on the little piston is F1. So, the little piston's pressure on the liquid is P = F1 / SI,
Hydraulic transmission has many outstanding advantages, so its application is very extensive, such as regular work. Plastics processing machinery, pressure machinery, machine tools, etc. Construction machinery, construction machinery, agricultural machinery, automobiles etc. Metallurgical machinery, hoisting device and roll adjusting device for steel industry; Flood control gates and levees of civil water conservancy projects, river bed lifting devices and bridge control institutions; Power plant turbine speed adjustment device, nuclear power plant and so on; Ship's deck lifting machinery (winch), bow door, bulkhead valve and stern thruster; A large antenna control device for special technology, measuring buoys, lifting and rotating stages, etc. Military industrial use of artillery control, ship stabilizer, vehicle simulation, landing gear for aircraft landing gear and rudder control device.
