I have used a 2 seal design for high vacuum applications, where I otherwise would get a very tiny leak through the seal upon moving it. The space in between the two seals is pumped to a rough vacuum, thus tiny leaks past the first are pumped away before going though the secound.
You could...
I,m looking for hints on how to optimize the design of a vacuum vessle (cylindrical) with a honeycomb, or foam core
wall.
I would like to minimize the density & thickness of the walls.
Thanks
