Yes, a smaller piston is going to have to be the way to go.
4" is pretty common and cheaply available, so I'll start there.
Then I expect heat to become more of an unavoidable problem as speed ramps up to get near desired cfm.
And an internal oiler/sprayer.
Design is the art of turning...
You are correct, this pond doesn't strictly need aeration.
But the 50-75 goldfish and Comets have survived 6+ years of Buffalo winters and seem to number about 200+ now.
This might help them a bit, and should in theory help reduce algae growth.
A piccolo tube or several spread out smaller...
Awesome, one of the equations mentioned PSIG but not how to arrive at it...
Ah, are you saying reverse the engine into a pump like a few people have done with VW Bugs?
I did think of doing that with an old push mower, but then I'd need much higher RPMs and noise.
If I can figure out some...
Snickster, thanks very much!
I'll admit that'll take a few to figure out.
But net-net I need 196 ft/lbs to compress, and power and stroke time are dependant upon available power and motor size, gearing?
Unless I misread what Force on Piston is 196 @ 9' is referring to.
Thanks, thats why I thought I'd at least ask.
As for panels, I've got a couple 100w 12v, which I know is not going to cut it. It might have for a smaller prototype.
I'll probably invest in a couple of 350w panels with my MPPT more realistically, and just go battery less and let it run when...
Fair point, I did not detail use case as some forums get bent for too much extraneous information.
This is for an aerator for a 45' pond 9' deep at the center, 40-50K gallons IIRC.
Its located 237' from the house, and trenching, conduit and/or groundproof wiring of large gauge to reduce losses...
Littleinch and Waross thank you very much, very.
Yes, this is pumping air into a pond at approx. sea level.
I guess I'm doing this from first principles mainly because it was difficult to a compression discussion that wasn't involving an air compressor to a holding tank or a pheumatic type...
Network engineer, so not a real Engineer or a Student Engineer; is it allowed to ask a Mech. Eng. question/s?
If so, I'm looking to build a simple air piston pump w/low CFM (5.5), delivering air to ~9' below water surface.
Q1- Since 9' is ~1/3 Bar, does that mean I need to provide PSI at 0.3...
