A pneumatic actuator is a mechanical device that uses compressed air to create motion. These actuators are crucial components in various industrial systems, including manufacturing, automation, and robotics, where they convert the energy from pressurized air into linear or rotary motion. This article explores the principles behind pneumatic actuators, their diverse applications, and the advantages they offer.
Principles of Pneumatic Actuators
Pneumatic actuators work on the basic principle of converting air pressure into mechanical force. Compressed air enters the actuator, typically through a valve, and causes a diaphragm or piston inside the actuator to move. The force generated by the movement of the piston can be used to drive a mechanical load, such as a valve, door, or conveyor. There are two main types of pneumatic actuators: linear actuators and rotary actuators. Linear actuators produce straight-line motion. They are often equipped with a piston inside a cylinder. When compressed air is applied to one side of the piston, it moves forward or backward, depending on the configuration.
