-
(Texas A&M University. Turbomachinery Laboratories, 1983)This paper presents a typical field problem that most maintenance engineers in any petrochemical plant could encounter. Two 4000 hp through-drive electric motors were totally destroyed when the inboard coupling failed. ...
-
(Texas A&M University. Turbomachinery Laboratories, 1986)The efficiency of compressor impellers, apart from the design, depends on some features linked with their manufacture. These features are the accuracy of geometry, the surface quality obtained, and the blockages which are ...
-
(Texas A&M University. Turbomachinery Laboratories, 2007)Abradable seals are employed in turbomachinery to reduce leakage gaps between stationary and rotating parts to improve efficiency and stall margin. Thermally sprayed abradable seals have been used in the compressor section ...
-
(Texas A&M University. Gas Turbine Laboratories, 1973)On-stream cleaning is regularly practiced on the axial compressors of gas turbines and on steam turbines. Many other turbo machines could be cleaned in service. In fact, the limiting factor is not the machine type, but the ...
-
(Texas A&M University. Turbomachinery Laboratories, 1988)Has the industrial standardization of the IBM PC/ AT as a building block for dedicated instrument computer systems brought costs down to the point where sophisticated monitoring systems are not only possible, but make good ...
-
(Texas A&M University. Turbomachinery Laboratories, 2003)Expander reliability has been limited by flow path erosion, corrosion, and deposition. Through root cause determination of the failures and laboratory testing, advances in machine designs and online monitoring and cleaning ...
-
(Texas A&M University. Turbomachinery Laboratories, 1990)Unpredicted bearing failures continue to plague industry with forced outages. As a result of these outages, many industries have attempted prevention by unnecessary inspections and premature bearing replacement. This work ...
-
(Texas A&M University. Turbomachinery Laboratories, 2006)This paper reports the results of a series of online water wash tests of a GE J85-13 jet engine at the test facilities of the Royal Norwegian Air force. The engine performance was deteriorated by injecting atomized saltwater ...
-
(Texas A&M University. Turbomachinery Laboratories, 2001)This paper outlines the typical problems seen in reciprocating compressors and shows that the existing type of monitoring systems, consisting of vibration level, rod drop, rod runout, and valve cap temperatures, often ...
-
(Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1988)Every industrial process which underlies our modern civilization involves the transfer of liquids from one level of pressure or static energy to another level, and, as a result, pumps have become an essential part of all ...
-
(Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1989)
-
(Texas A&M University. Gas Turbine Laboratories, 1978)This paper describes in condensed form the results of a research project initiated by the Forschungskuratorium Maschinenbau e. V. and carried out at the Institut fur Maschinenelemente und Konstruktionslehre of Darmstadt ...
-
(Texas A&M University. Turbomachinery Laboratories, 1988)The losses in turbine performance due to excessive leakages in the labyrinth seals can result in significant heat rate degradation to the turbine cycle. The modified packing arrangement described helps eliminate the rubs ...
-
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station; Texas A & M University. Libraries; Texas A & M University. Libraries, 2021)Two 2,900 kW (3,900 hp) oil – flooded twin screw compressors deliver fuel gas from sour gas processing system to Gas Turbine Generators (GTG) at Banyu Urip oil production facility in Indonesia. The compressors operate with ...
-
Operating Turbomachinery On Or Near The Second Critical Speed In Accordance With API Specifications. (Texas A&M University. Turbomachinery Laboratories, 1989)The question of when is it safe to operate turbomachinery on or near the second critical speed is addressed. A parallel evolutionary progression of the API rotordynamic specifications and rotordynamic analysis capabilities ...
-
(Texas A&M University. Turbomachinery Laboratories, 2002)Self-lubricating, self-contained fluid-film thrust and journal bearings have been in use since the 1920s. These bearing systems offer relative simplicity in a reliable, stand-alone package. Recent testing has shown that ...
-
(Texas A&M University. Gas Turbine Laboratories, 1975)The problem of a whirling rotor in a high pressure centrifugal compressor and the steps to arrive at a solution are described. Orbit shapes and vibratory motion are illustrated. Vibratory frequency ratios compared to ...
-
(Texas A&M University. Turbomachinery Laboratories, 2011)Centrifugal compressors are at times required to operate in or near the choke region. Various limits of the degree of allowable operation in choke have been established. Based on test data and numerical data, the behavior ...
-
(Turbomachinery Laboratories, Texas A&M Engineering Experiment Station, 2015)The results of a stability test on a centrifugal compressor during the full load test of the entire compression train are presented. A Magnetic Exciter was installed at the shaft end in order to excite the first lateral ...
-
(Turbomachinery Laboratory, Texas A&M University, 2012)A case history is presented pertaining to five pumping systems that operated satisfactorily until a new production requirement was imposed on the pumping systems. A new slurry product initially developed at lab scale was ...
