Hydraulic transmission as a liquid as the working medium, the prime mover mechanical energy into pressure energy of the liquid, the control element having a fluid pressure energy to the actuator, the actuator drive motor and load to achieve the desired power, the liquid the pressure energy into mechanical work organization process energy.
Pneumatic actuator means powered by compressed air source to drive and control the various mechanical devices to achieve mechanization and automation of the production process technique. Pneumatic fluid as the working medium to the compressed gas, or a fluid transmission power information transmitted by the pressure of the gas. Transmitting power system for delivering pressurized gas to the pneumatic actuators via a conduit and a control valve, the compressed gas pressure energy into mechanical energy to perform work; transmission of system information is the use of pneumatic logic elements or fluidic elements to implement logical operations and other functions , also known as pneumatic control system.
Characteristics of pneumatic transmission are: low working pressure, generally 0.3 to 0.8 MPa, small gas viscosity, resistance loss small pipes, facilitates centralized gas supply and transport distances, the use of safe, non-explosive and shock hazard, there overload protection; gear speed but low pressure, the gas source need. Pneumatic transmission and control of electromechanical specialty important professional basic course, which aims to make college to understand and master the basic structure for gas transmission and control, the basic working principle, the basic analysis methods and basic gymnastics skills, training students to analyze problems and solve problems ability and a certain ability to lay the necessary foundation for future professional work.
