You’re probably used to thinking of compressed air as being a forward force. It’s possible to also distribute it in the other direction meaning that you can actually make a vacuum using nothing but compressed air.
Ejectors, also called vacuum educators or even venturi, use a flow of positive compressed air flowing through a special nozzle to create a vacuum. In doing so, you won’t have to worry about a mechanical vacuum pump or any of the other pieces of gear you’d normally need when dealing with a piece of vacuum-driven equipment.
While it won’t be silent, that also means you won’t exactly have the huge whirring noise that’s normally associated with a vacuum. If you’ve ever been bothered by vacuum cleaner sounds in the workplace, then this might be particularly good news for you. That being said, you might want to take a few moments to better familiarize yourself with the way that it works before you invest in any physical hardware.
Making a Vacuum With Compressed Air
In short, vacuum generators use compressed air to generate a source of vacuum forces using a system referred to as a venturi. The venturi effect refers to the overall reduction of fluid pressure that results when a specific fluid flows through a choke of a link.
In this case, the fluid in question is normally the same air that comes from a compressed air-driven system and gets forced through it as a result of the actions of a compressor. The choke, in this case, is a constricted section of airline or pipe, much like you’d expect from any other piece of pneumatic equipment.
Giovanni Battista Venturi, an Italian scientist of the 18th and 19th centuries, originally discovered this effect. It’s now being put into excellent use by modern equipment produced in the 21st century that takes advantage of many developments that couldn’t have possibly been thought of in Venturi’s time.
You may want to be a little bit careful when using that term. Many technicians refer to the device itself as a venturi, though this is also the name of the discoverer and the effect itself. That being said, you don’t have to worry about being confused if you’re just trying to order all of the latest components from SMC Pneumatics. Simply mention a vacuum generator and we’ll make sure to hook you up with the right kind of equipment that should meet your organization’s requirements.
At its most simple form, the process of doing so uses no moving parts. That’s precisely why it’s so quiet compared to the kind of mechanical vacuum generator you’d associate with a vacuum cleaner. This also makes it incredibly reliable.
While you’ll often hear people talk about it being energy-intensive compared to mechanical vacuum pumps marked at the same flow rating, the fact that they need so little maintenance helps to even this out. Since they’re also quite safe, these pieces of gear might actually represent a significant cost reduction over time.
Multiple stage units with a suction flow that’s greater than 7 SCFM can generate vacuum levels that are as strong as -27 in HG, so you won’t have to worry about strength. While some people might debate certain aspects of an installation, you’ll never have to say anything about whether or not you can be sure that your equipment won’t be up to the task. Obviously, this should be more than enough for even the most demanding applications.
Best of all, air vacuum generators from SMC are capable of being connected via a manifold as well as used on an individual basis. In some instances, more compact devices can be customized in order to integrate suction filters and other goods. Depending on the specific needs of your organization and the installation that you’re planning, compressed air-driven vacuum generators can incorporate several other types of devices too.
Various Niceties For Those Who Work With Compressed Air-Driven Vacuum Generators
Suction filters are almost absolutely vital if you plan on using the equipment near anything that generates any amount of dust or other particulate matter. In addition, you can find a wide variety of other accessories that work with these excellent pieces of equipment. Since vacuum generators have gotten more compact over the years, they can now work with vacuum sensor switches as well as both supply and release valves that mount onto the generator.
These are offered in several standard sizes you won’t have to worry about whether or not they’ll fit either. That is because parts are relatively interchangeable in an overwhelming majority of cases.
All gear that’s a member of the SMC generator line can be configured to manage vacuum distribution from some sort of external vacuum source, be it one of these generators or another more complete module.
More than likely, the only question you might still have about this kind of technology is where you would be able to get your own. Fortunately, that’s not at all difficult because we’ve made sure to stock a wide variety of components that can help you kick start your operations and modernize the way that your firm generates vacuum power for any specific industrial processes that you currently use it for.
