I’m experiencing a very tricky leaking which I cannot address. I have a BR2 with aluminum enclosures, while we test it for 15 minutes at 26 Bar the pressure maintain perfectly is doesn´t move at all but when we had a dive it started leaking at 55 meters depth… we were very surprised fortunately the water did not affect the electronics (around 2 cm inside the 4 aluminum enclosure).
Once we removed water from the ROV we did the leak test again with positive results… the enclosure is not leaking at all. Once again we have sumbmerged but this time up to 20 meters for 10 minutes just to check again we found water in the ROV this time an small amount due that we submerged it only up to 20 meters.
So far we have checked:
- penetrators oring: all in place
- radial Orings: all in place
- Any cut on the cables from thrusters or lumen lights. nothing at all
- replaced vacuum plug
- Run the test with different vacuum pump. Same result
Any ideas how to proceed with anything else? Just want to point out the very first time we had water inside our bar30 was not responding and suddenly it came back to normal again. Is there a possibility that the bar 30 might be leaking?
