Pneumatic cylinders (sometimes known as air cylinders) are mechanical devices which use the power of compressed gas to produce a force in a reciprocating linear motion.
Like hydraulic cylinders, something forces a piston to move in the desired direction. The piston is a disc or cylinder, and the piston rod transfers the force it develops to the object to be moved. Engineers sometimes prefer to use pneumatics because they are quieter, cleaner, and do not require large amounts of space for fluid storage.
Because the operating fluid is a gas, leakage from a Pneumatic Cylinder will not drip out and contaminate the surroundings, making pneumatics more desirable where cleanliness is a requirement. For example, in the mechanical puppets of the Disney Tiki Room, pneumatics are used to prevent fluid from dripping onto people below the puppets.
Once actuated, compressed air enters into the tube at one end of the piston and, hence, imparts force on the piston. Consequently, the piston becomes displaced (moved) by the compressed air expanding in an attempt to reach atmospheric pressure.
Although pneumatic cylinders will vary in appearance, size and function, they generally fall into one of the specific categories shown below. However there are also numerous other types of pneumatic cylinder available, many of which are designed to fulfill specific and specialized functions.

In recent years, Shantou City has made great achievements in the development of people's livelihood science and technology around population and health issues such as population health, public safety, ecological protection, disaster prevention and mitigation. Down, the city will organize the implementation of a number of people's livelihood science and technology projects and plans, and strive to promote the resolution of hot issues of major people's livelihood.
Shantou City will popularize LED lighting in the public lighting field by the end of next year. The plan includes urban or rural enterprises, public institutions, state-owned enterprises and other financial or state-owned capital investment and construction projects, all of which replace all traditional lighting fixtures with efficient LED lighting products.
According to the planning of Shantou City, all new lighting projects in the above fields will adopt LED street lights, garden lights and landscape lights; the original non-LED lighting products will be completed in phases and batches by the end of 2014. This is also a practical move for the city to accelerate the development of people's livelihood technology and promote the application of energy-saving and environmental protection technologies.
