(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station; Texas A & M University. Libraries; Texas A & M University. Libraries, 2021)During workshop testing of a new 3-stage main air compressor, higher than expected vibration levels were detected at stage 1 and 2 at start up. They are high enough that the machine could not be brought to the full speed. ...
-
(Texas A&M University. Turbomachinery Laboratories, 2008)During the startup of one of the compression trains of an offshore platform, in August/2006, excessively high vibrations were observed at the high pressure compressor. The same problem was also verified one week later, ...
-
(Texas A&M University. Turbomachinery Laboratories, 1994)A wide variety of vibration and failure problems occur in reciprocating machinery and piping systems. Excessive piping vibration problems usually occur when a mechanical natural frequency of the piping system or compressor ...

(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station; Texas A & M University. Libraries; Texas A & M University. Libraries, 2020)Recent advances in camera technology allows the user to detect subtle motion and amplify that motion to a level visible with the naked eye. Furthermore displacements, phase and frequency of motions can all be determined ...
-
(Texas A&M University. Turbomachinery Laboratories, 2009)Energizing research and development on pumps in today’s emerging global and environmental context is envisioned as a major feature of the pump industry in the next quarter century. The mission for how to realize this vision ...
-
(Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1986)The visual study of cavitation in pumping machinery now plays an important role in its development-particularly where high stage energies are concerned. The incomplete picture provided by traditional head decay tests is ...
-
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station; Texas A & M University. Libraries, 2022)Electrical submersible pumps are assembled in oil wells to act as artificial lift methods. When water is present in the reservoir, oil-water emulsions are formed in the pump. These two-phase mixtures affect the performance ...
-
(Turbomachinery Laboratory, Texas A&M University, 2010)Barrios (2007) conducted an experimental work in which was demonstrated that the two-phase stage performance of an electrical submersible pump (ESP) is related to the impeller gas and liquid flow pattern as mentioned by ...
-
(Texas A&M University. Turbomachinery Laboratories, 2012)During operation of compressor trains by a variable speed drive system (VSDS), integer and non-integer harmonic currents are generated in the inverter. Via the electrical system of the inverter and the motor, an excitation ...

(Texas A&M University. Turbomachinery Laboratories, 2013)During operation of compressor trains by a variable speed drive system (VSDS), integer and non-integer harmonic currents are generated in the inverter. Via the electrical system of the inverter and the motor, an excitation ...
-
(Texas A&M University. Turbomachinery Laboratories, 2010)To satisfy API standard 617 (2002) stability requirements, the design of centrifugal compressors must be analyzed against the Level 1 screening criteria for self-excited subsynchronous instability of the rotor lateral ...
-
(Texas A&M University. Turbomachinery Laboratories, 1988)Ever since steam turbines have been built, contamination of the lube oil by water has been a persistent problem. Water contamination will result in rusting of ferrous components, accelerate sludging leading to sticking of ...
-
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2018)This tutorial provides guidance to help understand the causes, and to prevent or mitigate the effects of water hammer, or fluid transients, in piping and pipeline systems. The text of this paper is based on early drafts ...

-
(Turbomachinery Laboratory, Texas A&M University, 2011)A U.S. Gulf Coast refinery had experienced accelerated internal wear of FCCU cycle oil pumps, often requiring entire case replacements. Compared to typical industry pump performance, run lengths were shorter, and cost per ...
-
(Texas A&M University. Turbomachinery Laboratories, 2003)There are many types of couplings used on high performance turbomachinery. Explained are the differences in the various styles and configurations, and when one is preferable to another in certain applications.
-
(Turbomachinery Laboratories, Texas A&M Engineering Experiment Station, 2014)Every engineer has his own idea of what makes a centrifugal pump a high energy pump, but getting 2 or more engineers to agree on a definition of "High Energy" is difficult. Is a pump high energy because it runs at > 6000 ...
-
(Texas A&M University. Gas Turbine Laboratories, 1974)Optical alignment as we know it today was borne out of the aircraft construction industry. With the advent of necessity to maintain a straight line within closer tolerances and over greater distances, precision instrument ...
-
(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 ...
-
(Texas A&M University. Turbomachinery Laboratories, 2006)This tutorial addresses the question of which compressor type is better suited to a given application - a centrifugal or reciprocating design. The general application map will be presented and discussed, as will the advantage ...
