Hi Bill
The idea about the thermal expansion of oil is just an attempt to explain
why there may sometimes be a vacuum on a sealed rigid container with oil in
it. I think Vance mentioned that the oil filled battery pods sometimes had
a vacuum on resurfacing. I've been following your discussion. I thought the suggestion about a
compressible tube attached to the oil filled container was a good one. I
plan to use that to compensate the pressure inside of a winch on my boat.
I too think the oil will be messy, but the winch needs lubricant
anyway. Everything else I plan to compensate with air, and that currently
includes my battery box. My ambient dry sub, like the Sport Sub's
will free flow about 3 cfm into the cabin, but unlike the Sport Sub I am going
to route the exhaust from the cabin onto the other compensated areas. My
batteries will be gel-cell which I think produce less gas. Someone please
correct me here if I am wrong. Anyway, I plan to flow the air into one end of
the battery box, and out the other, which will help carry off some of the
gas. I can't think of any way that could be done in a wet sub. I
know you don't want to put the batteries over your head, or flow the air
through the battery box first. :) You sure you don't want to
convert to dry ambient?
Thanks for all your good discussions
