Access code:
  • Lab Update
    • Received BlueStik Glue to leak test the relief valve before replacement.
    • Applying glue on top brass shows lower leak rate. Valve to scroll pump was open while testing, so overall leak rate is lower than earlier projected.
    • Discussed with Matt about replacing relief valve. Mike applied small heat to the relief valve to prepare for replacement, later decided to complete replacement today.
    • This seems to have fixed the leak to a reasonable amount.
    • I will redo this test to confirm this today and start preparing for cooldown.
