Coupling Interface Connection.
(Texas A&M University. Turbomachinery Laboratories, 2001)
In rotating equipment, torque is usually transmitted from shafts to coupling hubs through keys, splines, friction, or a combination of these. Not covered in this tutorial are applications where the rotating equipment has ...
Maintenance And Online Diagnostics On Gearboxes In The Petrochemical Industry.
(Texas A&M University. Turbomachinery Laboratories, 2001)
As a result of cost reductions, there are fewer and fewer gear specialists in compressor and turbine companies, as well as in the maintenance groups of users. Therefore, these groups rely on the gear manufacturer’s expertise ...
Compressor Discharge Pipe Failure Investigation With A Review Of Surge, Rotating Stall, And Piping Resonance.
(Texas A&M University. Turbomachinery Laboratories, 2002)
Rotating stall, even with multiple cells, can contribute to piping excitation due to acoustic energy traveling down the pipe as a plane wave. The main objective of the paper is to describe causes and solution of fatigue ...
Rotordynamic Tests Of A Flexible Rotor On Flexure Pivot Journal Bearings And Stability Correlation With Frequency Dependent Characteristics.
(Texas A&M University. Turbomachinery Laboratories, 2002)
A series of performance, unbalance response, and stability tests were performed on a flexible rotor incorporating two flexure pivot tilt-pad journal bearings, followed by a theoretical correlations using synchronous and ...
Resonance Identification For Impellers.
(Texas A&M University. Turbomachinery Laboratories, 2003)
The reliability of centrifugal compressors for the most part depends on the reliable operation of impellers. Most of the time, damage to impellers is due to mechanical fatigue. Fatigue damage has been observed in blades, ...
Engineering Fundamentals Of Multi-MW Variable Frequency Drives - How They Work, Basic Types, And Application Considerations.
(Texas A&M University. Turbomachinery Laboratories, 2002)
A brief historical overview of the conversion from mechanical systems to electrical systems at low power levels is presented to gain an understanding of what is occurring at multiple megawatt (MW) power levels in industry. ...
Short Courses for the Proceedings of the 31th Turbomachinery Symposium
(Texas A&M University. Turbomachinery Laboratories, 2002)
New Technologies Of Synthesis Gas Compressor Drive Steam Turbines For Increasing Efficiency And Reliability.
(Texas A&M University. Turbomachinery Laboratories, 2002)
Recently, synthesis gas compressor drive steam turbines have required upgrading to increase efficiency and reliability for saving both operation and maintenance costs in many ammonia plants. This paper introduces the latest ...
Compressor Seals For Hydrogen Recycle Service.
(Texas A&M University. Turbomachinery Laboratories, 2002)
Hydrogen recycle service has presented a special challenge for centrifugal compressors and particularly the casing seals. Typical problems include the presence of liquids (condensables and water), hydrogen sulfide, chlorides, ...
