Using Non-Standard Materials for Couplings on Special Turbomachinery Applications
(Turbomachinery Laboratories, Texas A&M Engineering Experiment Station, 2016)
Technical Brief 3: Flexible couplings are a critical component in turbo-machinery train. It is a challenge and very important for coupling designers to select suitable materials for special turbo-machinery applications. ...
Dynamic Analysis of a Multi-Stage Compressor Train
(Turbomachinery Laboratories, Texas A&M Engineering Experiment Station, 2016)
Technical Brief 4: A complex multiple-stage compressor train which is part of an off-shore booster installation was facing process and mechanical related problems. The frequency of these problems has increased lately leading ...
Repair of Severely Damaged Rotor as an Emergency Spare
(Turbomachinery Laboratories, Texas A&M Engineering Experiment Station, 2016)
Case Study 10: When the subject compressor was opened for an unrelated reason, it was unexpectedly found to have severe cracking, including a missing piece, on the first stage impeller and foreign object damage to the ...
