What is Seal Failure in Hydrogen Recycle Compressor about?
1) A hydrogen recycle gas compressor experienced two dry gas seal failures within 27 months of operation due to high axial vibration. 2) Investigation found the compressor was experiencing sub-synchronous axial vibration around half running speed, peaking at 2.5 mils, causing accelerated wear on the seal. 3) Installing a new pre-loaded thrust bearing reduced axial vibration by over 75% and resolved the seal failure issue after 1 year of operation with low vibration levels.
