Converting Energy With High Performing Pneumatic Actuators
Supporting a wide range of applications, pneumatic actuators are the workhorses of transmission power and expansion power. Pneumatic systems are highly efficient in processes involving holding a load for a length of time. Actuators enable automation of a valve, and can be remotely controlled to engage shutdown mechanisms in emergencies.
Pneumatic actuators convert compressed air into mechanical motion, and are well suited for applications where human interaction isn’t possible due to space, location or safety considerations. A wide range of motion types can be achieved, depending on the operating pressure and temperature, load capacity and maximum torque of the actuator. Pushing or transmission power is realized, as well as expansion power within any compressible liquid.
Piston style pneumatic actuators are compact and offer long-lasting performance and reliability. The larger the size of the piston and rod diameters, the more output pressure is increased. One of the more common actuator types, these actuators can produce powerful movement can tolerate adverse conditions like dry and dusty environments as well as high humidity and high pressure cleandowns.
Eliminating friction metal-to-metal, pneumatic actuators with double-acting cylinders use the force of air to power both the outstroke and the instroke. Speed control is enhanced as the exhausting back pressure is controlled. This type has two ports for the input of air, one at either end of the piston, for opening and closing the valve. Preventing rod buckling and bending, a well designed cylinder will manage the longer strokes required in some applications.
A single acting or spring-return configuration in a pneumatic actuator means that compressed air supply is restricted to just one side of the piston. The energy causing movement is generated through one port of the actuator and once rotated in the opening or closing of the valve, then springs back to the original position.
A wide range of industries is well served by pneumatic actuators, from the petrochemical industry to refining, water treatment and wastewater disposal, and general power generation. Simple and easy to operate through automated systems as well as being safer than other ways to generate motion, these actuators operate air compressors, switches, sensors, pumps and robotics with reliability over a long period of time.
High Tech Design
One of the simplest ways to accomplish the conversion of compressed air into mechanical energy is through the use of pneumatic actuators. In designing an actuator to achieve the greatest output in terms of motion or force, certain companies are focused on extensive research and development into high performance.
