-
(Texas A&M University. Turbomachinery Laboratories, 2010)Pump adds an ingredient to a reaction vessel. Both short periods of loss of flow and long periods of excessive flow variation will impact product quality. Correct performance of this pump is critical to uptime and first ...
-
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station; Texas A & M University. Libraries; Texas A & M University. Libraries, 2021)This case study examines a repeat compressor coupling failure that was a result of a complex, dynamic interaction of components that excited the 2nd torsional natural frequency of the train. The mature unit had operated ...
-
(Texas A&M University. Turbomachinery Laboratories, 2008)For mechanical drive steam turbines, the investigation results of corrosion fatigue phenomena in the transient zone are introduced, including basic phenomena on expansion line and actual design and damage experience. These ...

(Texas A&M University. Turbomachinery Laboratories, 2011)
-
(Turbomachinery Laboratories, Texas A&M Engineering Experiment Station, 2016)This paper presents details of investigation results of issues observed during plant start-up on a centrifugal compressor. Compressor was operated with air/ nitrogen during start-up and high shaft vibration (approx. 75 um) ...
-
(Turbomachinery Laboratories, Texas A&M Engineering Experiment Station, 2016)Blade failure was observed on a backpressure steam turbine (driving a centrifugal compressor) after it was in service for more than one year. This paper presents details of observations, inspections carried out and root ...
-
(Texas A&M University. Turbomachinery Laboratories, 1991)Clearances between sealing devices of rotating and stationary components of turbomachinery have always been important to engineers in controlling gas leakages. One way of accomplishing this is by the use of abradable seals ...
-
(Texas A&M University. Gas Turbine Laboratories, 1978)With turbine rotors of low shaft elasticity (large diameter and small bearing span) the increase in amplitude at the first point of shaft resonance in the speed range is generally slight. Consequently no particular attention ...
-
(Texas A&M University. Turbomachinery Laboratories, 2013)The shop performance test of a hydrogen recycle gas compressor for refinery plant was conducted with the suction pressure of 50barA based on ASME PTC-10 Type-2 test. During testing, a surge phenomenon was observed at a ...
-
Investigations Into The Contamination Of Lubricating Oil In Rolling Element Pump Bearing Assemblies (Texas A&M University. Turbomachinery Laboratories, 2000)The use of rolling element bearings in pumps is standard practice. Of the many factors that affect their long-term performance, contamination in the bearing lubricating oil plays a major part. Of particular concern are ...
-
(Texas A&M University. Turbomachinery Laboratories, 2009)For many application fields of turbocompressors the rotor stability has become the most important part of the rotordynamic analysis. A comprehensive knowledge of these seal forces is mandatory to ensure an adequate overall ...
-
(Texas A&M University. Turbomachinery Laboratories, 2010)
-
(Texas A&M University. Turbomachinery Laboratories, 1995)From time to time vibration probes pick up high vibration at the coupling location on output shafts. Many times the coupling will then be removed and sent to the shop or to the manufacturer for inspection, repair, and ...
-
(Turbomachinery Laboratory, Texas A&M University, 2011)International standard ISO 13709:2009 (Identical), ANSI/API Standard 610: September 2010 “Centrifugal Pumps for Petroleum, Petrochemical and Natural Gas Industries” also referred to as ISO 13709 Second Edition / API Eleventh ...
-
(Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1990)The standards used so far by European manufacturers of chemical process pumps were only dimensional: ISO 2858, BS 24256, DIN 24256, NF E 44121. The pump manufacturer had total freedom of design provided outline dimensions ...
-
(Texas A&M University. Turbomachinery Laboratories, 1984)A review of several different types of hydrodynamic journal bearings that are commonly found in turbomachinery is presented. Emphasis is placed on the key geometric design parameters of each type. The discussion covers ...
-
(Texas A&M University. Turbomachinery Laboratories, 2010)
-
(Texas A&M University. Turbomachinery Laboratories, 2008)Peculiar, low-frequency, radial vibrations have been observed in various turbomachinery using tilt-pad journal bearings. Unlike discrete subsynchronous spikes that often indicate a serious problem, the vibrations are ...
-
(Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1995)A few well established hydraulic design parameters define the internal quality of an impeller design. Becoming familiar with those parameters and understanding their limits will enable pump buyers to make better pump buying ...
-
(Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1995)Many facilities do not obtain the expected life out of ANSI and other centrifugal pumps, seals, and bearings that need to be obtained to be competitive in today’s market place. The analysis of this situation leads to two ...
