Lego Vacuum Pump

Quick build and test of a Lego pump that sucks air. It can generate a 70% vacuum.
At the end I show another Lego way to create vacuum: Lego pneumatic pump pushing air out of a jar. This can generate a 63% vacuum. Water boiling test to prove the gauge was correct. Enjoy!

Try putting two or three of those in series, I would like to see if the vacuum increases in strength

Cascading... That's actually a very good idea. Should work. I wonder to which % vacuum you could get with, say, three of these in series.

[@joelrayside3374]

we call this staging in refrigeration vacuum pumps. single stage, two stage.

[@SkigBiggler]

Your main issue here is that the seals won’t be adequate to hold a decent vacuum. Air will likely permeate in through the tubing and seals.

It will pull vacuum faster, but the ultimate vacuum achieved will be about the same.

[@philcorrigan5641]

I think maybe the seals are a big limiting factor here

[@hamjudo]

@@philcorrigan5641 put an entire vacuum pump with vacuum chamber into a larger vacuum chamber with a higher volume pump. When the outer chamber is pumped down to 0.3 bar absolute, the inner pump's seals will see 0.3 bar as the external pressure, so that pump has a chance of reaching a significantly lower pressure in its much smaller chamber.

[@kjamison5951]

Can I just point out that -20psi is an impressive vacuum. My former manager told me that a -20psi vacuum is an aeronautical standard. I believe him, although I haven’t found any evidence to support that just yet. He previously worked in the aeronautical industry.

[@jacobcombs1106]

That is in inches mercury(in Hg) not PSI. considering they are at standard atmospheric pressure in their room which is only about 14.5 PSIA so a -20 PSID would make the inside of the jar -5.5PSIA which is not possible. But 20 in HG is about 9.8 PSI which is still impressive as it means the pressure in the jar is only about 4.7 PSIA. Now if you pressurize a space to above atmospheric pressure you can then experience differential pressures where there is an apparent vacuum of 20 PSI, but not in the conditions of this video.

Great, dude!

[@AgentWest]

Why a two-position valve instead of a simple check valve on that first one? You can make a really simple one by heating up an end of one of those blue tubes, then pinching and holding the end until it cools. Just don't heat it so hot that it sticks together and seals the end.
