Load Dependent Critical Speed
(Texas A&M University. Turbomachinery Laboratories, 2010)
Dynamic Stress Measurement Of Centrifugal Compressor Impeller And Study For Strength Criteria Based On Correlation By Unsteady CFD
(Texas A&M University. Turbomachinery Laboratories, 2010)
Based on the development of numerical analysis techniques over the past decade, the engineer can easily model the internal flow conditions and vibration characteristics of turbomachinery. When focusing on vibration response ...
Gear Box Failures Due To Bull Gear Slippage
(Texas A&M University. Turbomachinery Laboratories, 2010)
Bull gears slippage in speed multiplier of compressor trains occurred on two FPSOs offshore Brazil. These events produced high impact on the amount of flared gas and also in oil production. After being called, the supplier ...
Protective Systems For Turbomachinery - What Is The Right Level? How To Verify?
(Texas A&M University. Turbomachinery Laboratories, 2010)
Journal Bearing Upgrade To Solve Reliability Issues In An Accessory Gearbox
(Texas A&M University. Turbomachinery Laboratories, 2010)
Prevention Of Shaft End Damage Due To High Contact Pressure
(Texas A&M University. Turbomachinery Laboratories, 2010)
Modeling Of Rotor Bow During Hot Restart In Centrifugal Compressors
(Texas A&M University. Turbomachinery Laboratories, 2010)
Rotor bow during hot restart is a common cause of high vibrations in turbomachinery. It may occur after the shutdown of a machine operating under load, if the rotor is left cooling in standstill condition (no turning gear) ...
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 ...
Centrifugal Compressor Evolution
(Texas A&M University. Turbomachinery Laboratories, 2010)
This paper addresses the advancements that have been made during the past 50 years in the design, analysis, and manufacturing methods for centrifugal compressors. The paper provides a historical perspective on these ...
