Pneumatic Actuators
A pneumatic actuator is a device that uses compressed air to convert fluid energy into mechanical motion, either linear or rotational. They're a common choice for automating valves, clamps, and other machinery because they are simple, powerful, and clean.
How They Work
The basic principle of a pneumatic actuator is straightforward. Compressed air is introduced into a chamber, where it exerts pressure on a piston or diaphragm. This pressure moves the piston or diaphragm, which is connected to a rod or shaft. This motion is then used to perform work, such as opening or closing a valve, or clamping a part.
The force generated by the actuator is determined by two factors:
The pressure of the compressed air.
The surface area of the piston or diaphragm.
A larger piston and higher pressure result in a more powerful actuator.
