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. They are usually used in the application of industrial manufacturing in order to use for pumps, inflow-control valves, positioning drives, switches, meters, and relays. There are actually different kinds of actuators such as the pneumatic air actuator, linear actuator, rotary actuator, electric actuator, hydraulic actuator, piston 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.


Even though there are different kinds of actuators already out in the market today, still the most commonly used these days will be the hydraulic or the Siemens 331-4311 electro-servo types of actuators. Simpler tasks are actually made used of with the hydraulic actuator's fluid power in order for the tasks to be done. The liquid referred to as the one being used for this machine is called the hydraulic fluid. The hydraulic fluid is then transmitted into the motors of cylinders and then it will then be controlled with the valves. Because of the fact that hydraulic machines produce very high and intense amounts of power, the power it produces is actually enough to support multiple actuators in one go. While linear actuators actually have a piston in order for it to set a stroke, If you have been wondering how hydraulic pressure is actually created, it is actually created by the constant pushing and pulling of the piston at a fixed force and fixed length. 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.


And in order to turn energy into motion, pneumatic actuators on the other hand, would actually use air to compress it and then convert it in to said energy. More information on this are displayed in our site. Each kind of actuator actually produces its own specific kind of motion , such as the oscillatory or even the linear, and it all depends on what type of actuator you will be using. The pneumatic kind usually contains a piston, its valves or ports, and then a cylinder. It is then enclosed with a diaphragm that serves as protection for the piston that actually keeps the air right at the upper part of the cylinder. 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.
