What does hydraulic technology mean
Hydraulic efficiency is widely used in industry and civil industry due to its large transmission power and easy transmission and configuration. In the manufacture of components, has high technical requirement to impermeability, durability, at present has been widely used in hydraulic components manufacturing - rolling process, a good solution to the problem of the roundness, roughness. Especially in hydraulic cylinder manufacturing. Hydraulic tools can solve hydraulic problems.
A complete hydraulic system consists of five parts: the power component, the actuator, the control component, the auxiliary element 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. Hydraulic valves can be divided into pressure control valves, flow control valves and directional control valves according to the control function. The pressure control valve is divided into overflow valve (safety valve), pressure relief valve, sequence valve, 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.
The hydraulic technique USES PASCAL's law: the pressure on the closed liquid, the ability to pass PASCAL's law in all directions. 2, so in a small area on the piston of exert a small force, because the transmission is the pressure, so, on the other side of the large area of the piston would be a greater force. Hydraulic efficiency is widely used in industry and civil industry due to its large driving force and easy transmission and configuration. In the manufacture of components, has high technical requirement to impermeability, durability, at present has been widely used in hydraulic components manufacturing - rolling process, a good solution to the problem of the roundness, roughness. Especially in hydraulic cylinder manufacturing. Hydraulic tools can solve hydraulic problems.
of course, there are also some simple equipment, he can't so complicated hydraulic cylinder, there are some relatively simple hydraulic cylinder, exhaust system, for example, in some simple there is no such element on the hydraulic cylinder, he is more cheaper compared with that in, no matter what kind of hydraulic cylinder, his principle is the same, the hydraulic pressure can be converted into mechanical energy, do reciprocating linear motion.
