What kind of flow rates? 350 bar is a lot. Iirc Sulzer uses plunger pumps to pumps on their engines to develop that kind of pressure, and that's with much more viscous fuels.

For a Detroit: Flow is controlled by a rack and pinion. The injector has a helix cut into it and as the body rotates, that helix dumps excess fuel sooner or later - which changes the injected volume. See the rod that is transverse to the body? That's the helix revolving mechanism. If you google...

Sorry, I thought the end goal of this was to use the whole thing to run a blower? Like a massive steam plant leaf blower?

That's where copper-nickle alloys come out to play. Forgive my memory, where does the air blower go?

I should mention that with certain centrifugal actions, dead heading also causes less loading on the prime mover, because it is maintaining static pressure and not moving anything. So peak pressure and peak power input share a weird relationship. You can feel this effect by covering and...

For centrifugal pumps, this is true. Deadheading them causes max pressure.

All the pumps listed above require ultra high pressure lubrication. Lubrication beyond the point that fluid film lubrication breaks down. That's the roll of zinc or calcium packages in hydraulics oil. Pumping water, they would be basically unlubricated.

I'm wondering if you need a speed reducer, I've never heard of an impeller running so fast. You might have issues with cavitation? Have you designed a blower yet? Are you going axial or centrifugal?

Sorry I only dabbled is variable displacement pumps and have nothing to offer regarding equations, but you could always put a bucket X feet up to get a head and calculate that water columns are roughly 2.2 feet per pound, if memory serves. The measure flow rate and multiply it out. Very nice...

Very nice setup.

The tank is fed from the drain port on the compressor, not the air compressors quick connect, so the water from the compressor is continuously expelled. The air/water get injected down a steel pipe to the piston. The piston lifts and drops as needed, so that it always forms a minimal circular...

Great site, I would say that the amazon bucket cyclone I linked to suffers from the issues he lists as common issues with commercial units. It's especially sensitive to interruptions in the air flow which makes stuff from the bucket, swirl up and into the vacuum. In a sand blasting hood, that...

The "Dust Stopper" in the video looks like it is a Thien separator. Those are probably worth looking into as an easy and effective home build.

his site is...Highly detailed. this will take some time to read through...

Found the Amazon bucket cyclones work better if you toss in one of these: 2PCS 9.25'' Car Wash Washboard Insert Bucket Dirt Remove Filte Black 23.5cm https://a.co/d/73qQvr2 For me it really cut the amount of material that escaped the bucket. But I also put swarf through the same system.

You gotta week😉 But seriously, wood cuts really fast on a metal lathe with sharp HSS knives. I can take 1/4" cuts with ease on my wee taig lathe. With a machine big enough to spin your wood, I bet you could hog even more.

Can you just cut squares and load them onto your lathe?

Very cool, thank you for sharing!

Any pictures of this set up, perchance?

Shhhhh it's a secret.
