Pneumatic actuators are in broad use in industry wherever rapid, powerful linear actuation of shifting gates, valves, levers and presses may be needed. Pneumatic actuators are available in a number of configurations covering single acting, double acting, and double acting with piston rod attachments on both ends of the actuator. Pneumatic actuators come with holes and strokes of cantles of inches all the way to a few feet. Smooth pneumatic actuator is powered by compressed air at pressures ranging from a few pounds to hundreds of pounds each square inch and can offer thousands of pounds of push or pull force.
Smooth pneumatic actuators use a smooth bore cylinder with a piston attached to a piston rod, with a few circumferential seals between the piston and cylinder. The piston rod has a smaller rod sustain bushing and seal between the smooth piston rod and the bottom of the cylinder. They are most often composed of metal components, even though many composites are employed for special applications. They are available with all kinds of mechanical end connection fittings and pneumatic piping and tubing connections.
Systems employing pneumatic actuators to act repeated linear motion cycles are simple to take shape, structure and connect. Plastic tubing may be applied to bring the pneumatic sign to the actuator. Pneumatic systems are in essence safe in explosion proof only places where there may be a existence of flammable or explosive gases or fumes. Pneumatic actuators are also one of the best patterns to manufacture a large linear force in a small room at relatively low expenditure compared to electric and hydraulic systems. Where a reliable source of compressed air already presents, pneumatic electric actuators offer an economical way to automate equipment.
Compressed air is expensive to make because the special concessions for cooling and drying the compressed air must be held. Also, provisions must be produced for piping compressed air with tubing aimed for compressed air. The behavior of compressed air is fully distinctive from pressurized water and should never be piped with PVC plastic pressure pipe due to the potential of shattering plastic being boosted away from breaks and impacts. If the compressed air is not suitably dehydrated in refrigerate, desiccant, or membrane dryers, water will go its way into components in the compressed air stream and lead to erratic performance.
Compressed air cylinders are existed in a number of automotive and building applications covering jacks and hoists, door, gate, and hatch motors. Interesting jumping cars employ pneumatic actuators to leap the suspension. Until now, the greatest application is in the industrial areas where pneumatic cylinders are used as actuators for valves, lift doors, cranes, and machines.
Some smooth pneumatic actuator applications do not need exterior power, since they serve to perform as dynamic buffers or shock dampers. The most common instance is an easy domestic one -- that door nearer cylinder on a screen or storm door sustain the door from either opening or closing too sharply, while offering a spring that lightly closes the door.
