    • CST05 - Fluid-Film Bearing Damage Detection Based on Vibration Data� 
      Yu, John; Peton, Nicolas (Turbomachinery Laboratory; Texas A&M Engineering Experiment Station; Texas A & M University. Libraries, [2019])
      This case occurred during startup after outage on a steam turbine generator. Vibration reached over full scale of 20 mil pp at generator drive end bearing and therefore tripped the unit. The major vibration component that ...
    • Detection of Misalignment from Vibration Data 
      Yu, John; Péton, Nicolas (Turbomachinery Laboratory, Texas A&M Engineering Experiment Station; Texas A & M University. Libraries; Texas A & M University. Libraries, 2020)
      On a boiler feed pump driven by a motor running close to 3600 rpm, a horizontal misalignment issue was suspected by examining orbit plots besides shaft centerline plots. The follow-up inspection did uncover large parallel ...
    • High Vibration Due to Steam Turbine Deposits 
      Yu, John; Zhou, Tony Wei; Lin, Haibo; Wang, Carl Feng; Peton, Nicolas (Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2018)
      This presentation provides a case study how to correctly deal with increased vibration on a steam turbine that drives a compressor. After the machine had not operated for a week, vibration level increased 5 times during ...
    • Pelletizer Motor Bearing Damage Detection Based on Vibration Data 
      Yu, John; Feng Wang, Carl; Wei Zhou, Tony; Lin, Haibo; Quan, Ju; Peton, Nicolas (Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2017)
