Something to
keep in mind when using CO2 for pressure compensation: gaseous
CO2 when combined with the humidity expected to be found in a
submersible and it’s components forms carbonic acid so you will see
accelerated corrosion of metal surfaces and electronic/electrical components
will be rapidly degraded. Nitrogen or air is a better choice…air
should be easier to obtain and will cost less. Remember KISS! Another choice
is to oil fill the motors, mineral oil is often used or some other dielectric
oil (preferable non-explosive) can be substituted. This reduces the
number of systems required to operate your submersible and thus decrease the
probability of failure. Plus it doesn’t require any internal or
external space. A good set of
hard or soft mechanical seals negates the need for any of this. Respectfully, Jay K. Jeffries Andros Is., It is the mark of an educated mind to be able to
entertain a thought without accepting it. From: owner- In a message dated 10/17/2006 3:42:53 PM Central Daylight

thanks George will keep it on the maybe list. I was also
thinking about the cooling atributes as it would be vented off. Seems every
time i would vent to lower pressure some cooling would happen, cool electric
motors I know is good. Was thinking of using it in the lead acid battery
compartment for the 1 atm in there, to reduce chance of ignitions. |
