Pipeline Stage Design For Increased Operating Range.
(Texas A&M University. Turbomachinery Laboratories, 2007)
With the continuing increase in energy demand, pipeline compressors are being challenged to cope with both large flow rates and broad operating range flexibility, driven by the local seasonal markets. Overall, high efficiency ...
Practical Use Of Rotordynamic Analysis And Troubleshooting Skills To Correct A Long-Term Synchronous Vibration Problem In An Overhung Turboblower.
(Texas A&M University. Turbomachinery Laboratories, 2002)
The two subject blowers operate in parallel to circulate wet chlorine gas. Both units had large synchronous vibrations that led to multiple bearing failures. After simple rotordynamic studies failed to identify the problem, ...
Hermetically Sealed Oil-Free Turbocompressor Technology.
(Texas A&M University. Turbomachinery Laboratories, 2005)
The reciprocating compressor and the traditional centrifugal compressor have been the workhorses of the natural gas industry. However, new demands placed on gas distribution infrastructure by spot market activity necessitates ...
Turbine Failure And Reconstruction.
(Texas A&M University. Turbomachinery Laboratories, 2005)
This paper is an extended case history of a turbine catastrophic failure due to stress corrosion and the reconstruction of the turbine, compressor, gearbox, and the drive motor after a fire. Wheel stresses and the design ...
Axial Alignment And Thermal Growth Effects On Turbomachinery Trains With Double-Helical Gearing.
(Texas A&M University. Turbomachinery Laboratories, 2005)
Turbomachinery shafting and casings typically experience axial growth during thermal transients occurring at startup, shutdown, and changes of load. This growth does not usually present difficulties during operation. ...
API Specification Review For Gas Turbine Driven Turbocompressors.
(Texas A&M University. Turbomachinery Laboratories, 2006)
This tutorial provides an overview of the latest edition of American Petroleum Institute (API) Code API 616 (1998) and also provides a brief summary of API 614 (1999), 617 (2002), 670 (2000), 671 (1998), and 677 (1997) as ...
Design, Manufacture, And Testing Of A High Speed 10 MW Permanent Magnet Motor And Discussion Of Potential Applications.
(Texas A&M University. Turbomachinery Laboratories, 2006)
The paper will present the design, manufacturing, and testing of a high speed 10 MW permanent magnet motor and discussion of potential applications. The paper will cover from concept through design and development to the ...
What To Do When A "Classic" RCA Doesn't Give The Answer - Apply Detailed Engineering Analysis.
(Texas A&M University. Turbomachinery Laboratories, 2006)
A methodology is presented to identify the most likely cause of failure for a cat cracker hot gas expander in which the “classic” failure mechanisms did not fit the evidence collected after the failure. Because the classic ...
The Role Of Online Aerodynamic Performance Analysis.
(Texas A&M University. Turbomachinery Laboratories, 2006)
Continuous online aerodynamic performance monitoring of turbomachinery is crucial to plant operation and maintenance and is a key part of a thorough machine reliability program. Integrating machine real-time performance ...
Development And Testing Of A Very High Speed Oil Lubricated End Face Mechanical Seal.
(Texas A&M University. Turbomachinery Laboratories, 2009)
Six large radial inflow turbines were designed to expand isobutane for two electric power plants in Nevada which use heat from the earth (geothermal energy) as the energy source. Double end face mechanical seals lubricated ...
