-
(Texas A&M University. Turbomachinery Laboratories, 1992)A serious radial gear vibration was determined to be caused by significant torsional excitation from a squirrel cage induction motor that was controlled by a variable frequency current source inverter drive. Field test ...
-
(Texas A&M University. Gas Turbine Laboratories, 1980)Recent designs of high and medium pressure centrifugal compressors show a well-behaved response to forced vibration and an adequate margin to self-excited vibration. This can only be achieved by an extensive rotor dynamic ...

-
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2018)The lecture presents measurements of leakage and dynamic force coefficients for six annular seals operating with an air in oil mixture ranging from pure liquid to just air. Each seal has a distinct clearance configuration: ...

-
(Turbomachinery Laboratories, Texas A&M Engineering Experiment Station, 2014)Mechanical seals are the most common means of sealing industrial centrifugal pumps. There are a wide variety of seal options including the use of single or dual seal arrangements. While dual seals provide benefits in leakage ...

(Turbomachinery Laboratories, Texas A&M Engineering Experiment Station, 2013)Mechanical seals are the most common means of sealing industrial centrifugal pumps. There are a wide variety of seal options including the use of single or dual seal arrangements. While dual seals provide benefits in leakage ...
-
(Texas A&M University. Gas Turbine Laboratories, 1975)Compressor and driver shafts often prove to be overstressed in equipment uprate situations. This paper shows how a change from conventional gear-type couplings to the more recent diaphragm coupling design can lower the ...
-
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station; Texas A & M University. Libraries; Texas A & M University. Libraries, 2021)A benefit claimed for vane compressors is they do not have vibrations problems that are experienced by other positive displacement machines. This case study demonstrates high vibration and fatigue failures on a sliding ...
-
(Texas A&M University. Turbomachinery Laboratories, 2008)About 40 to 50 percent of the power required for the operations of a typical offshore oil and gas platform is used for gas compression. Miranda and Brick (2004) described a comprehensive procedure that could be applied to ...
-
(Texas A&M University. Turbomachinery Laboratories, 2004)This paper describes a comprehensive life cycle cost (LCC) analysis procedure, regarding turbomachinery systems for offshore oil and gas production platforms. The LCC analysis includes the development of a cost breakdown ...
-
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2018)The main driver to define the time between overhauls of a gas turbine is the life of the hot components. For an Oil&Gas operator, a turbine overhaul represents a major cost and therefore is a key point for performance ...
-
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station; Texas A & M University. Libraries, 2022)NGL shipping pumps have experienced high number of mechanical seal failures during the first five years of operation. There are five pumps where each pump is equipped with two mechanical seals. In some instances, the ...

Limitations of ASME PTC 10 in Accurately Evaluation Centrifugal Compressor Thermodynamic Performance (Texas A&M University. Turbomachinery Laboratories, 2013)The American Society of Mechanical Engineers (ASME) “Performance Test Code on Compressors and Exhausters,” ASME PTC 10-1997, has served worldwide as the standard for determining centrifugal compressor thermodynamic performance ...
-
(Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1992)In view of the inflammability of LNG (liquefied natural gas), submerged type pumps are normally used to protect against leaks. The overhaul interval of an LNG pump, therefore, is subject to the life of its ball bearings, ...
-

-
(Texas A&M University. Turbomachinery Laboratories, 2013)This paper presents results of the large scale testing of the first two stages, including incoming sidestream flow of a LNG propane compressor. The large scale test was performed at 90% scale of the production propane ...
-
(Texas A&M University. Turbomachinery Laboratories, 2010)
-
(Texas A&M University. Turbomachinery Laboratories, 2011)One of the primary causes of flow path failures in industrial axial flow compressors has been attributed to or is related to corrosion damage. Over the years, a number of corrosion mitigations have been utilized by various ...
-
(Texas A&M University. Turbomachinery Laboratories, 1999)At most industrial facilities, the engineering, maintenance, and operation groups are under great pressure to increase reliability and also reduce costs. This paper discusses the role of operators in achieving low cost ...
