Introduction: hydraulic and pneumatic transmission are in fluid medium, to achieve energy conversion, transmission and control.
Hydraulic and pneumatic transmission is the use of various components (hydraulic components or pneumatic components) with different components of the basic loop control function, and then a plurality of basic circuit transmission system for energy conversion, transmission and control of basin. In order to study the subject, must master the hydraulic fluid mechanics and gas mechanics foundation knowledge, Huo to be familiar with the characteristics of various types of performance of system components, working principle, structure and performance of these components is composed of various fragrant this control loop, the design based on the needs of the host load hydraulic and pneumatic transmission and control system.
The liquid hydraulic transmission medium has the advantages of stepless speed regulation and stable transmission, so it has been widely used in grinding, blending, pulling, planing, machine; because of its convenient arrangement and easy automation, in combination machine used widely, due to the implementation of components of the output force (or torque), large easy operation, flexible hydraulic components and electrical appliances, and easy to realize automation and remote control in metallurgical machinery, mining machinery, drilling machinery, hoisting machinery, construction machinery, plastic machinery, agricultural machinery, hydraulic machine, forging machine, aircraft and ship in many of the commonly used hydraulic transmission control mechanism. However, because of the high resistance to hydraulic transmission, it is not suitable for long distance transmission. The working medium is air pressure transmission, which has the advantages of low pressure, high speed, high pressure, high pressure, high pressure, high pressure, high pressure, high pressure, low pressure, high pressure, high pressure, high pressure, high pressure, high speed, high pressure, high pressure, high pressure, high pressure, high pressure, high speed, high pressure.
