Vacuum pump with NO moving parts

I demonstrate the importance of surface adsorption and use it to produce a clean, low cost type of vacuum pump.
Note: If you ever notice the pressure meter go blank don't worry, there wasn't an issue. The meter automatically turns off to save power.

[@dizzolve]

We had a terrible principal when I was in HighSchool

[@V0S1N0]

He seems to have hinted that it could also be used to separate a solvent in an extracted oil? Could he fill a column with the beads and then run solvent across an organic material like peppermint/garlic, dumping the output into the column full of beads, where the beads will adsorb the solvent letting the oil pass through? I guess you could weigh all the gear at the start and tell by weight how much separation you got. Hmm.

[@BrokeWrench]

@@V0S1N0 depends on the physical size of the particles, but it does seem that the process takes time at high concentrations, so you would likely need the molecular sieve to sit in the solution. This is a common way to purify ethanol to 100% after distillation

[@arfink]

We use cryopumps in my job to pump very large volumes down to high vacuum. They're quite cost effective at that scale, and have an important advantage over a turbopump, in that they can fairly easily deal with gasses that are intentionally released into the vacuum system during a process. Turbos also have trouble with non-gaseous particles, whereas a cryo will not be damaged by such things. Turbos can be much more sensitive also to heavy stuff like noble gasses, where a cryo can just condense whatever you throw at it, within reason. With a pair of pumps, if one becomes saturated, it can be closed from the system with a valve while the other continues to work, and regenerated without compromising the vacuum chamber. They're definitely more "primitive" than some kinds of vacuum tech, and can have serious drawbacks, but within their niche they are extremely useful.

[@timphillips3275]

thank you for that info.I want to learn as much as I can on subject.

[@absalomdraconis]

Out of curiosity, have you ever experimented with hooking another pump in to regenerate the cryo pump without removing it from the system? I'm personally curious about vacuum ejector systems that scavenge their working fluid from the material to be removed, but the general case is a point of curiosity itself.

[@excitedbox5705]

@@absalomdraconis By removing it from the system he means closing a valve and not physically taking it out. If you look at how o2 concentrators work that is exactly what they do. They have 2 chambers full of the filter medium (Usually something to filter nitrogen) and while one is working the other is regenerated and then a valve switches over and the other works while that one is regenerated. To regenerate them you just need to heat it (with internal heating elements) causing the gas to expand and boil off. These systems are often used by glass blowers because they need huge amounts of oxygen to "fuel" their torches.

[@absalomdraconis]

I love the videos, but on a smaller/lower resolution screen, it can be challenging to make out the various instrumentation measurements seen in your videos. If you agree this is an issue, I'd suggest adding little "expanded view" enlargements. These should be fairly easy to do for static shots in your video editor. On a different note, I found the description of how our visual systems respond to low oxygen strikingly magical.

[@hankscactus3973]

Brilliant video. You are completely correct that the use of heat blankets or lamps will increase the pump down rate on vacuum chambers. In semiconductor equipment, traps like these are often used to reduce contamination from oil filled vacuum pumps from ever reaching the high vacuum chambers. One effect that we had to teach vacuum maintenance workers... Virtual leaks. A video explaining what a vented screw is and how big an effect a virtual leak can have on a high vacuum chamber would be awesome. A factory can lose so much time waiting for the base pressure to never be achieved due to this cause. Hope your day is really good.

I was involved in building two of these in college back when the cheapest pre-built system my university was able to get was coming in at $1.8M. The two we built only cost $67K in total, basically pocket change in comparison. This takes me back for sure, really interesting stuff and I'm glad to see someone covering it. We used liquid helium to cool ours, like you mentioned, and we used custom built ceramic heating coils running with a very complex array of thermometers to monitor heating and cooling. The hardest part was building the heating and cooling arrays, a lot of extremely fiddly TIG welding and expensive fittings went into them. We did use the sheet configuration you mentioned, the sheets were manufactured by one of my professors and his team of post-grads in the materials science department. It was a huge project, we went through a variety of prototypes. It took us a year and a half to produce the final pump. Our very first (functional) proof of concept looked a lot like what you have in this video, and it worked *almost* as well as the final full scale pump. Great video, I really enjoyed seeing you explain the concepts behind it. What you said about physical principles and their utility as tools, that's very insightful.

[@mceajc]

I'm curious to see how well the heating/cooling effect might have without the beads. Just by heating the gas molecules, the pressure would be raised enough for the pump to remove a few more, and cooling it back down would lower the pressure. Then it can be a straight comparison for the performance of the beads.

[@leonardpearlman9509]

There are for sure Zeolite traps which are not refrigerated, and might have heaters attached to them somehow. So, they do SOMETHING (catch water I think, which is important) and/or catch the oil from the mechanical pump. You can buy them for either service, not too expensive. Simple and rugged. I think the cryogenic one has much higher performance, but the heater-only kind might be cheaper to run, and just in general be big and dumb.

I really like how he described how a molecular sieve works, I have some oxygen concentrators and I was always curious about how the molecular sieve work in it

Love the way that you smirked when you said "fusion" towards the end of the video. Very confident that if we can task you to put together a tech ingredients video on cold fusion, we may finally actually get it :)

Fascinating! I’m always thrilled to see an alert for a new video from TI.

Tech Ingredients is like that science teacher that you really didn't appreciate in high school but as an adult you realize is genius.

You Sir I have the most respect for, on all of my KZbin videos and in life. You truly are the most informative, educational and knowledgeable source I have ever had the pleasure of seeing. Thank you so much for everything you do. Possibly meeting in person one day would be a treat for myself. If I ask you a question it would be, with all your information, what do you expect other to do with it. Make devices or use it for future generations? Add to it to help you find a use for it. I guess it's not the best questions, but I am in no way as intelligent or industrious as you. One could only try to compare and gain from everything you have given of yourself. Again, the highest respect, and appreciation for you.

Back in the 1982-84 time frame I worked on ion beam implanters for the dopping of silicon wafers in the process of making IC chips. We would vacuum Down a chamber first using a mechanical diffusion pump then cryogenic pump after all the items stopped out gassing due to the low pressure we could reach down to the milli tore range this would take about 3 days I do not recall the size of the chamber. This demonstration brought back memories thank you.😀🛫

This guy is like a "black hole" for physical knowledge, and WE volks have the great chance to watch BEHIND his event horizon ... (A realy supermassive black hole !) Thank you so much !

This man is brilliant I could listen to him all day

[@RedFenceAnime]

I really appreciate that you take the time to clarify words. I've spend so much time on other videos trying to listen to what they said exactly. This was definitely "kind of interesting." Thanks for another great video.

In the early '90's I worked at a vacuum metallization company. Their equipment used to plate thin layers of metals on various items in a vacuum to make jewelry.Once a base metal was on, the item could then go through chemical electroplating, such as gold. One experiment they took a dead butterfly and plated it.
