Pneumatics is the science and technology of pressurized air, using piped, compressed air (or a gas such as nitrogen) to transmit force and energy.
Pneumatic and Hydraulic systems has been used for many years within industrial processes. The development of fluid power technology over the years has increased the applications to many areas for the adoption of pneumatic and hydraulic technology.
Some of the users of fluid power technology are:
- Manufacturing industries: packaging, automotive industry, machine tool manufacturers and commercial appliance manufacturers.
- Processing industries such as chemical, petro-chemical, food processing, textiles, paper etc.
- Transportation systems, including marine and mobile construction plants
- Defense systems
Components of Pneumatic systems
Pneumatic cylinders, rotary actuators and air motors provide the force and movement for the most of pneumatic systems, for holding, moving, forming, and processing of materials. To operate and control these actuators, other pneumatic components are needed such as air service units for the preparation of the compressed air and valves for the control of the pressure, flow and direction of movement of the actuators. A basic pneumatic system consists of the following two main sections.
- Compressed air production, transportation, and distribution system
- Compressed air consuming system
The main components of the compressed air production, transportation, and distribution system consist of air compressor, electric motor and motor control centre, pressure switch, check valve, storage tank, pressure gauge, auto drain, air dryer, filters, air lubricator, pipelines, and different types of valves.
