Advisory Committee / Turbomachinery Symposium (39th : 2010)
(Texas A&M University. Turbomachinery Laboratories, 2010)
Shop Acceptance Testing Of Compressor Rotordynamic Stability And Theoretical Correlation
(Texas A&M University. Turbomachinery Laboratories, 2010)
This paper presents the rotordynamic stability testing of a nine-stage centrifugal compressor used for hydrogen recycle service. The machine tested was of a basic design and employed no damper bearings, damper seals, shunts ...
Measurement Of Dynamic Performance Of Large Tilting Pad Journal Bearing And Rotor Stability Improvement
(Texas A&M University. Turbomachinery Laboratories, 2010)
Capacities at today’s modern ethylene and refinery plants have steadily increased, giving rise to a growing demand for larger compressors and more powerful drivers all of which require larger rotating parts. In keeping ...
Investigation of Steam Turbine blade failure
(Turbomachinery Laboratories, Texas A&M Engineering Experiment Station, 2016)
Blade failure was observed on a backpressure steam turbine (driving a centrifugal compressor) after it was in service for more than one year. This paper presents details of observations, inspections carried out and root ...
