Basically for everything that needs decent suction.ĭisclaimer: I only provide the files and assume you know what you do with the nozzle! I am not responsible if your printed nozzle fails due to poor print quality. Of course to make bubbles in your bath ) If you need a bit of vacuum, for example to degass resin, you can do this not without an expensive pump. After a few not so good ones I now have a little nozzle that is strong enough to deflate a soda bottle, don't have a vacuum gauge at hand but it really sucks enough to feel it on your finger when closing the air vent. I wanted something that not only sucks well (sorry for the bad joke!) but also provides a lot of pressure on the outlet so the bubbles are dispersed properly. There are quite a few 3D models available for Venturi systems but they are either meant for the use with compressed air or need far too much water. If you have no clue what that is check Wikipedia. No, I decided to make a little venturi nozzle! Take a hose from the compressor instead? ) My little niece complained about her bubble bath not having enough bubbles! So what can the good uncle do about it? Add an air pump and bubble stone? - Takes far too long. In a good creek power jet, In puddle jumping use the suction nozzle.Update: : Added two models for the use on a compressor instead of using water. The idea is that if you are using a jet flare and should you pop the hose out of the water and lose prime the pressure jet may blast material out of the box, find the angle in which the jet blows over the sluice should somthing bad like that happen. This may be different than yours, I'm not sure if you have a crashbox or a jet flare. The jet inlet position doesn't matter too much on my dredge as I still use the old crashbox style header. The jet log will get better gas mileage than a suction nozzle and provide better suction should you keep it floating on the pontoons. Figure out what rocks to throw away and not hog the nozzle and you will do well. The nozzle restriction will rob your production, fill with small rocks and reduce the flow over the box, the gravels compact, clear the nozzle, and your boxes scour. Don't put any kind of restriction on the nozzle! It's all bad! Get a snorkel and mask and look what is going up the nozzle.
