At a big science lab I worked at once I saw a magnetically levitated turbopump which had the width of a 24" computer screen if not even some few inch bigger.. yea you could have crawled inside it and they had 2 just about to be mounted. They were not cheap.. at all.
Mag Lev technology is so cool...
@@johnmorrisscientific So dam cool, and they never wear out which normally is the reason they are much, much more expensive then hybrid ones sine they never break so they have to put a price on them to earn in that during the pump lifetime.
Thanks for your sharing
Thanks for watching!
How does one motivate the molecules to float towards the first compressor stage?
If it’s classical high vacuum system , you have lighter gases such as hydrogen and helium. Which will remain these molecules tend to stick to the chamber walls . Heating the chamber energises the molecules and they will then move off the walls and through random molecular collision they will then be presented at the entry of the pump to be moved from the chamber .
What is the bearing (if that's the right name) shown at 0:37? I don't understand how the molecules getting caught between that and the engravings in the animation translates to real life; those engravings should be smaller than the size of machining signs on the inner surface of the envelope. (I'm note a native English speaker I hope you understand)
Why would you let RUclips stabilize a animated video...?
What is the price of a suitable turbomolecular pump to be used for vacuuming a chamber to aluminizing telescope mirror?
More than whatever is affordable for you.
Some people have found functional turbomolecular pumps with controllers that could be used for such a purpose as aluminizing mirrors for a couple hundred bucks (in the US and with extensive manual and automated searching and patience, looking for I would guess over a year or more). In Europe probably double or triple that. If you didn’t want to search and wait and just buy one used for the typical price, you could probably find one, with controller, for 1.5-2.5k$ fairly easily. Or use a diffusion pump which you can probably find used for $100-400.
Can I ask a question?
yea what is it
@@asdasdasf213 You aren't the uploader
your pumps might be magnetically levitated to reduce vibrations but your video is shaking like hell
RUclips was stabilizing the video by default. is Fixed Now. Thanks for pointing that out klazzera & Leo
@@johnmorrisscientific wow thanks for such a quick fix that was awesome, now i watched your video again
@@klazzera glad it helped!
