Subtracting Residual Unbalance For Improved Test Stand Vibration Correlation.
(Texas A&M University. Turbomachinery Laboratories, 1997)
The importance of correlating rotordynamic analytical results to actual test data has become extremely important in recent years. Many user specifications require the verification of vendor generated analytical results in ...
Short Course T5: Lateral Rotordynamics of Petrochemical Equipment - Review, Examples & Problems
(Texas A&M University. Turbomachinery Laboratories, 2012)
Low Frequency Instability In A Process Compressor.
(Texas A&M University. Turbomachinery Laboratories, 2004)
A catalytic gas process compressor experienced low frequency vibrations in excess of trip levels following installation of a honeycomb balance piston. After 12 years of operation, low seal oil differential forced an unplanned ...
Torsional Oscillation Trouble on VFD Motor Driven Recip Compressor
(Texas A&M University. Turbomachinery Laboratories, 2008)
High vibration problems including failed coupling parts on a VFD motor driven reciprocating compressor are analyzed and the root causes and solutions are discussed in this costly field issue.
Development and Implementation of VFD Active Damping to Smooth Torsional Vibrations on a Geared Train
(Texas A&M University. Turbomachinery Laboratories, 2008)
VFD Induced Coupling Failure
(Texas A&M University. Turbomachinery Laboratories, 2008)
A catastrophic failure of a high performance disc coupling connecting the speed increaser and LP compressor in a VFD controlled 18,300 HP motor/speed increaser/LP compressor/HP compressor train, led to months of reduced ...
