The only time I have mental instability is when I'm in stupid Calgary traffic.
Thanks , a little luck won't hurt.
I have solved my pump problem !!! (mebbie)
This has been a rather major hurdle.I've spec'd out pumps of every type and design.I've had people laugh when I told em the required operating specs.The cryogenic pumps I have seen are many thousands of dollars.
So when in doubt , build it.
To this end , today I found and purchased just what I needed :
A 67 mm (2 5/8") 3-blade brass RC racing boat prop ;
I'll be putting this prop inside a 3" copper tube like so :
You can pretty much figger out where this goes......I'll be attaching the prop to a variable speed belt system and a 1/3 HP motor....I need to fabricate shaft bearings , and output barbs onto the copper tube but thats no big deal.....
Considering what the final product will be made from , I see no reason this pump won't operate at -200C let alone the -100c I want.
