Garden hose venturi pump by jag Aug 23, 2012

Description

I designed this to mix a small amount of liquid fertilizer into a stream of water from a garden hose.
I have a worm composter that produces quite a bit of liquid fertilizer and I wanted to dilute it and sprinkle it on my lawn.

This looks perfect for a soap injector for my small power washer with garden hose hookup. I could then use a gallon of siding wash and have it suck it in before the power washer. All i need now is a anti flowback valve at the outdoor spigot so that soap can't get pulled back into the household lines and i would have something that costs around $80 online! Brilliant!

Instructions

Print it out.
Break out the little support cylinder in the bottom and cut out the think membrane over the hole.

Place a rubber washer in the female threaded end.
Tap the vacuum port with a 1/8 NPT tap (don't force it and crack the plastic)
The hole is already tapered so hopefully it shouldn't be too much work to tap it.
Insert whatever 1/8" npt fitting you want into the port (JG fittings are nice)

Hook it up inline with your sprinkler or whatever.

Would this work for injecting bubbles or as a vacuum pump?

jag on Aug 26, 2012 said:

It should, it doesn't cut the bubbles up particularly small and I'm not sure how much vacuum it will pull. Maybe I'll put a gauge on it some time.

Nope, a thing-o-matic at 80mm/sec (peak)

Very nice! I've been waiting for a printable venturi something or other. Not that I need one, but it seems a natural thing. Actually what I really want to see is a printable vortex tube for cooling, now that'd be fun...

Thanks! I was a little surprised that there wasn't one already.

There were a few venturis around but none of them were openscad so, rather than bodge some threads onto one of the other designs I just started from scratch.
