Pneumatics

Pneumatics is the application of air or other gases to achieve motion, power, and control. Using the principles of pressure and motion, pneumatics systems are generally less expensive to install and maintain than hydraulic systems, and offer flexibility that hydraulic systems cannot. In many cases, pneumatically-powered applications are simple to use and maintain, while providing a high level of performance.When pneumatic systems are utilized, pressurized air or other gases are directed through a conduit, manipulated by valves and other controls, and applied to a movable member such as a cylinder or motor. When compressed air is contained within the chamber, the motion of the pneumatic device is created as a result of the rapid expansion and release of the air. Depending on the application, additional devices such as pressure relief valves, regulators, and flow controls may be used to improve efficiency.Pneumatic systems are used in a wide variety of applications. Common industrial uses include vacuum pumps, HVAC systems, packaging systems, robotics, machine tools, and process control systems. In addition, pneumatic systems are also used in automobile production, amusement parks, and automated factories.

Hydraulics

Hydraulics is the application of liquid as a means of generating and controlling power. By using the principles of pressure and motion, hydraulic systems can provide the power required to move objects, and the precision required to control them.Hydraulic systems utilize liquid in a chamber to generate motion. Generally, a hydraulic pump provides pressurized liquid to the movable member through a series of tubes and valves. Pressure relief valves and regulators are often used to improve the efficiency of the system. The motion of the movable member is controlled by the valves and the flow of liquid.Hydraulic systems are used in many applications where precise control is required. Common industrial uses of hydraulic systems include construction equipment, material handling equipment, aerospace systems, and robotics. In addition, hydraulic systems are also used in automotive and machine production, waste management, and container handling.
