ODS Operating Deflection Shapes
Looseness of a vacuum pump's frame
Measurement: triaxial vibration with phase
Analyzer: Adash VA5 Pro / VA3 Pro / DDS / MDS software
Solution:
- anchor bolts changed
- additional concrete filling of the frame
Downtime: 1 day intervention
Result: Vibration level reduced from 10-15 mm/s to ~1,6-2 mm/s, RMS
