How A Pneumatic Air Actuator Works
An air actuator is actually a kind of mechanical device that was designed to convert any electrical signal into something that creates a physical action. These devices are more typically used in the manufacturing industry set-up because of how it is used in inflow-control valves, meters, pumps, relays, positioning drives, switches, motors, and much more. The different kind of actuators include hydraulic actuator, piston actuator, electric actuator, linear actuator, rotary actuator, pneumatic air actuator, and more. Since each kind is of different form, then it also is operated by a certain form of energy source as well, an example would be storing compressed gasses or liquids for the potential, mechanical, and electrical energy.
Though it is true that there are so many types of actuators to choose from, still the most used are the ones that are of electro-servo and as well as the hydraulic kinds of actuators of the site at www.hvacbrain.com. Simpler tasks are actually made used of with the hydraulic actuator's fluid power in order for the tasks to be done. It is actually the hydraulic fluid that is made use of for this kind of device or machine. The hydraulic fluid is then transmitted into the motors of cylinders and then it will then be controlled with the valves. Any machine that is using hydraulic power can actually produce a high amount of power and therefore a whole lot of actuators can actually rig up from this power alone. Linear types of actuators on the other hand have pistons that are used for setting a stroke. Hydraulic pressure in these specific types of actuators are actually created with the pull and push of said piston but at a fixed length and fixed force. This kind of hydraulic pressure is then placed on one end so it then forces the piston for moving to an opposite end, which then results to the rod pushing in order to extend it. As the hydraulic pressure gets reversed, it will then cause the rod to actually stroke back into its original position.
The Siemens 331-4811 pneumatic actuator on the other hand is typically used for compressing air to produce energy that will therefore be created into motion. Depending on what kind of actuator you are using, it actually produces a variety of specific motions as well, just like the linear and the oscillatory kind of actuators. The pneumatic kind of actuator actually is made out of ports or valves, a cylinder, and then a piston. There is a diaphragm that protects the piston while it also keeps the air just within the cylinder's upper part. So all in all, it is important to know what kind you are going to use so you will get the right results for it.
