-
(Texas A&M University. Turbomachinery Laboratories, 1988)The lube oils in self-contained reservoirs for turbomachinery in hydrocarbon processing plants are subject to contamination and deterioration from airborne dust, component debris, system corrosion, heat, and water. Oil ...
-
(Texas A&M University. Turbomachinery Laboratories, 2009)This paper presents validation of a novel method for assessment of the centrifugal pump cavitation erosion with two configurations of a model feed centrifugal pump: with thru shaft, and Cantilever impeller. The method ...
-
(Texas A&M University. Turbomachinery Laboratories, 2012)The operation of a reciprocating compressor is closely linked to the performance of its valves in terms of life and efficiency. Most operators report that the most significant cause of forced outages of reciprocating ...
-
Vane Pass Vibration - Source, Assessment, And Correction - A Practical Guide For Centrifugal Pumps (Texas A&M University. Turbomachinery Laboratories, 1999)With the ever-increasing use of hand held vibration analyzers, data collectors, and predictive maintenance programs, a more complete understanding of vibrations is ever more important. This tutorial treats one of the most ...
-
(Texas A&M University. Turbomachinery Laboratories, 1984)In the past, large compressors in the petrochemical industry were mostly driven in one of two ways: by steam (or gas) turbines or by constant speed electrical motors. If the flow of the compressor had to be controlled, two ...
-
(Texas A&M University. Turbomachinery Laboratories, 2009)In 2009, the authors designed a compressor drive steam turbine for air separation units (ASU) application up to 200 MW (268,000 hp), using large 500 mm (19.7 inch) blade rows, which have a low-pressure (LP) flow capacity ...
-
(Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1994)Vertical diffuser type pumps, their application, construction, specialties and installation are discussed. Also, system curves and pump curves are handled.
-
(Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1988)Vertical diffuser type pumps, their applications, advantages, disadvantages, multistaging, manufacturing, material selection, construction possibilities, operation, and repair are reviewed. Also discussed are semi-open and ...
-
(Turbomachinery Laboratories, Texas A&M Engineering Experiment Station, 2014)
-
(Texas A&M University. Turbomachinery Laboratories, 2008)A 4160V, 3600 RPM motor on an existing vertical pump suffered a major failure attributed to a lightning strike. After repair vibration levels were well above shutdown with the motor running at above 1 inch/second. Several ...

(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2018)Suggested Topics: Petrochemical industries Installation NPSH Materials Bearings Maintenance Vibration Lubrication Paper industries Power industries Tolerances Nozzle loads
-
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station; Texas A & M University. Libraries; Texas A & M University. Libraries, 2020)When natural frequencies are well separated from machine generated vibration/forcing frequencies there is little amplification, but when not well separated significant vibration amplification can occur due to resonance. ...
-
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2017)
-
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2018)The subject pump was designed and installed when pipeline pressure was estimated high based on a higher production volume. The selected multistage vertical turbine-pumps are generically prone to vibration issues due to its ...
-
(Turbomachinery Laboratories, Texas A&M Engineering Experiment Station, 2013)Design and development of vertically-suspended water pumps requires good understanding of the rotor system characteristics with water-lubricated rubber bearings (WLRB). This paper presents a newly-built experimental device ...
-
(Texas A&M University. Turbomachinery Laboratories, 2005)Preliminary process design in 1997 for a new grass roots polymer unit in the Gulf Coast raised the possibility of using a single centrifugal pump instead of two reciprocating compressors to feel ethylene into the reactors. ...
-
(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 ...
-
(Turbomachinery Laboratories, Texas A&M Engineering Experiment Station, 2016)Turbomachinery requires a higher level of vibration analysis than general purpose machinery. This includes identifying natural frequencies or modes of a system to determine if a potential resonance occurs. The complexity ...
-
(Texas A&M University. Turbomachinery Laboratories, 1986)Vibration field data was measured on several large motor-driven vertical cooling water pumps which experienced excessive wear of the impellers, wear rings and seals after a short period of operation. The data indicated ...
