Why would you consider it worth your while to complete with the likes of Graham, Penberthy, etc.? This doesn't make engineering sense. And then after going through all this, you have to confront a worse reality: there are already existing, recognized, proven, reliable ejector suppliers out in the market place. It takes money, money, & probably more money to develop a credible, reliable, and recommended design of an ejector. Obviously, you've never designed one before that's why you're probing for help. No one - even you - is going to have any serious engineering faith in your first ejector design. If you "have to find the best way to design an ejector" you have probably stumbled into the best, practical, and experienced engineering recommendations from these fellows.įace the facts. Some of the best engineering minds you could attract - such as Milton Beychok, Torricelli, etc. RE: Liquid ejector design mbeychok (Chemical) 29 Dec 04 17:24 Or contact someone that makes eductors/venturis/ejectors/injectors etc.
So, first you need to specify your application for the ejector in order to help solve your ejector problem. Be ready to dish out upwards of $5,000 US.
The companies that are set up to conduct this test are few and far between. In addition, designing an ejector or venturi eductor requires a tremendous amount of bench testing based upon the "application" for the ejector.įor example, if the ejector will be used for aeration, then you will have to conduct a standard oxygen transfer efficiency test. However, you can purchase one and cut it in half and measure it.
That is why many manufactures cast ejectors. The internal dimensions for ejectors is not something an ejector manufacture likes to disclose.
First, why do you want to reinvent the ejector.
