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.
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 ...
