Pneumatic actuators are industrial applicators that are highly safe and reliable motion control devices. They work by converting energy into linear or rotary motion. They are common in industrial settings where valves are repeatedly opening and closing. Pneumatic actuators achieve their work using what is known as the pneumatic actuator working principle, and you can learn more about the principle here.
What Are The Different Types Of Pneumatic Actuators?
The pneumatic actuators come in different types. The choice is always essential; the different industrial mechanical movements require each unique type. This helps them convert energy from the compressed air to generate mechanical movements. Here are some of the common types;
• Vacuum Generators
• Rotary actuators
• Tie Rod Cylinders
• Rodless Actuators
How Does The Pneumatic Actuator Working Principle Work?
The pneumatic actuators have a working principle within which they operate. They come in two forms; the Piston operated and the Diaphragm Operated. The pneumatic actuators work by generating energy through compressed air. The instrument air then builds up pressure or force, which applies against the Piston or diaphragm. This, in turn, moves the pneumatic actuated valve into position on the valve stem resulting in mechanical movement.
The two main factors that make air suitable for powering this motion are easily compressible and absorbed. Additionally, it has a heightened safety level compared to other gasses. The pneumatic actuators are pretty popular in the industrial manufacturing sector for the fact that they can convert compressed air into kinetic energy, which can also be controlled to a high degree.
Pneumatic actuators are essential because they help control systems by providing a control signal to a plant to get the desired output. The positioning of the pneumatic actuated control valve with the diaphragm’s movement corresponds to the mechanical movement.
