Perpetual operations - some purists may have been harmed

[Leif]

I had an idea that I simply had to get out of my head, and the best way to do that is by exercising the very same idea!

Instead of batteries, use a power transformer (for stationary builds and for testing)

Instead of the wee Lego pump, look in your own garage.

Warning, not for the purist faint of heart

Pneumatic stuff bought at Swedish Biltema for approx 5€

i hope you dont blow up your pneumatics; maybe it would work pretty well for large pneumatic engines.

If too much pressure builds up I think the hose would just pop off, rather than destroy the pneumatics.

I got strange ideas, I'm not foolish!

the machine is a small one but it can produce 8 bar / 116 psi so I use the Air Pressure Regulator of course, set it at approx 2.5 bar / 36 psi.

Btw, the Lego pneu pumps can produce around 3 bar so at least should be in the margins when it comes to hoses and cylinders.

Good thing to have confirmed is that the Arocs crane behaves wonderfully at 2.5 bar. You can do several movements at once and nothing depends on gravity to work.

It means two things: good design and I have not cramped any hoses in my build

That's a good idea. It would be handy for running pneumatic GBC modules at events.

It could be interesting to see how much overpressure the LEGO pneumatics can take. Do you have a high speed camcorder?

There is a pressure adjusting valve on the end of the Air tank here (Its Red). Adjust that Red valve and you can bring the total output air pressure down to safer psi for LEGO use. The ideal air pressure in the air tank is 120 psi.
