- A compressor with fluid film bearings runs at 7700 RPM. The diametral clearance of the journal in the bearing is 10.0 mils and the measured displacement is 3.8 mils peak-to-peak. What maintenance recommendation applies? Cite your source(s).
- The time waveform form a generator’s inboard bearing shows an effective peak acceleration of 0.30 g pk when operating at 1200 RPM. Use the Modified Blake Chart to rate the generator’s vibration severity.
