Had kind of a brainstorm on the way to a job this morning, and curious if anyone has tried anything like this:
Install an oversized ds injector downstream of the regular injector. Set it up to have a few different detergents/solutions in small batches gravity fed through metering valves.
The spring would have to be removed a la Bob’s modded injectors because the injector won’t be pulling enough of a vacuum to pull soap with it there.
My reason for this hairbrained idea is that, as much as I love my stainless proportioning injector, I’m sort of restricted as to how much surfactant is in my mix. If I want to mix up a batch of building wash solution with some butyl or caustic degreaser to cut the road grime I’m a bit stuck, as well.
I think it’d be kind of cool to be able to tweak my solution on the fly for each scenario. But I know this is overcomplicating things
Those are proportioners in the suction tubes. They make some for drop tubes. A local Aaladin dealer gave me a bag of them when they were trying to schmooze me. Never tried them.
@squidskc is right. I use the GP high draw ,run all my soaps,acids at 100 percent ,then put my proportioners at the end of my DS 1/4 poly tubes,. Change my ratios on the fly using different proportioner colored tips. Just a cheap way to regulate my acids and soaps. The DS adjustable ones or metering dials don’t work for me. My acids eat them up to quickly. Got a strainer basket that twists on the end. So it’s a 1/4 barb that goes in the poly line,porporationers screw into that, then strainer basket screws on to that. $20
Or redneck engineer it ,like I did the red tip in the pic above and use a lil propane torch to heat up the 1/4 poly line, screw your proportioner in then let it cool. Molds itself via heat
I’ll run out of film on my phone before I get enough before/afters on those. I don’t even care if I do just one or two, I want the pictures to showcase.
I am hoping to find out today if they are interested. He met with his VP yesterday and told me to call today. They currently have someone but I really doubt it, as I have never seen a clean tractor or trailer. Hell, I haven’t seen a semi-clean tractor or trailer since they started.
Correct, you can use X-Jet proportioners to obtain your desired draw rate. You’ll have to do a draw test to see what tips are pulling what ratios but once you get this down you can “set it and forget it”
