Development And Application Of A Vertical High Speed Motor-Compressor Simulator For Rotor Drop Onto Auxiliary Bearings.
(Texas A&M University. Turbomachinery Laboratories, 2009)
During the conceptual development of a subsea motor-compressor prototype running on active magnetic bearings, the emergency landing on the catcher bearings was identified as a potential technology gap. This is because the ...
Assessing Liquid Droplet Erosion Potential In Centrifugal Compressor Impellers.
(Texas A&M University. Turbomachinery Laboratories, 2009)
This paper presents a method for estimating the potential for liquid droplet erosion in compression system components, such as the impeller of centrifugal compressors. The erosion model selected is used to calculate a ...
Diagnosis And Solution Of High Noise And Vibration Issues After A Propylene Refrigeration Compressor Rerate.
(Texas A&M University. Turbomachinery Laboratories, 2009)
Synchronous Motors Start up as Induction Motors
(Texas A&M University. Turbomachinery Laboratories, 2006)
Fundamentals Of Fluid Film Journal Bearing Operation And Modeling.
(Texas A&M University. Turbomachinery Laboratories, 2005)
Widely used in turbomachinery, the fluid film journal bearing is critical to a machine’s overall reliability level. Their design complexity and application severity continue to increase making it challenging for the plant ...
Applied Risk And Reliability For Turbomachinery Part I - Reliability Processes And Part II - Reliability Calculations).
(Texas A&M University. Turbomachinery Laboratories, 2005)
There are several methods of analysis to define the reliability of the critical rotating equipment at various facilities within a company. Part I of this tutorial is intended to present several of these methods. The following ...
Professional Staff / Turbomachinery Symposium (36th : 2007)
(Texas A&M University. Turbomachinery Laboratories, 2007)
VFD Induced Coupling Failure
(Texas A&M University. Turbomachinery Laboratories, 2008)
A catastrophic failure of a high performance disc coupling connecting the speed increaser and LP compressor in a VFD controlled 18,300 HP motor/speed increaser/LP compressor/HP compressor train, led to months of reduced ...
A New Method of Accurately Identifying the Location and Movement of Forward and Backward Bending Modes Using Magnetically Suspended Rotor Systems
(Texas A&M University. Turbomachinery Laboratories, 2008)
Rotordynamic calculations done on most turbomachinery often discount or even completely ignore the “backward” modes. In fact, many rotating equipment engineers have never observed a backward mode, leading some to doubt ...
ASME PTC 10 Modified Test For Mechanical Assessment Of Centrifugal Compressors.
(Texas A&M University. Turbomachinery Laboratories, 2007)
The rotordynamics paragraphs of the latest version of the API 617 Standard (2002) have been thoroughly reformulated and the prevention of subsynchronous vibrations and instability phenomena are dealt with in a very ...
