-
(Texas A&M University. Turbomachinery Laboratories, 1992)The selection of flexible couplings is often considered to be routine because there are a variety of proven designs available. A compressor retrofit that required variance from standard coupling design practice is discussed, ...
-
(Texas A&M University. Turbomachinery Laboratories, 1988)A total online condition monitoring system has been in operation on the world's largest offshore facility located off the coast of Norway. The Ekofisk platforms are operated by the Phillips Petroleum Company Norway and ...
-
(Texas A&M University. Turbomachinery Laboratories, 1987)Results are presented from data obtained from the cumulative experience of eight utilities which are conducting periodic, computer based predictive maintenance (PM) programs at their fossil stations. These programs are ...
-
(Texas A&M University. Turbomachinery Laboratories, 2001)Four 580 HP cooling tower feed pumps were upgraded by retrofitting improved bowl assemblies with enclosed stainless-steel impellers. Pumps exhibited capacity limitation up to 50% of rated and cavitation damage in original ...
-
(Texas A&M University. Turbomachinery Laboratories, 2005)To cover the remaining operation life of an offshore platform, it was necessary to go from a single stage compressor to a two-stage compressor. The design of the new two-stage compressor required two different impeller ...
-
(Texas A&M University. Turbomachinery Laboratories, 1995)Evaluations of life cycle costs in typical turbomachinery installations have shown that for reliable machines, energy costs normally far outweigh purchase, installation, and maintenance costs. Experience has shown that ...
-
(Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1987)A numerical method computer program has been developed by the authors that enables calculation of the wear inside a slurry pumping casing. The capabilities of the program are presented along with a description of how it ...
-
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station; Texas A & M University. Libraries; Texas A & M University. Libraries, 2021)A series of journal bearing tests were conducted to acquire more detailed information on the behavior of individual pads in a tilting pad journal bearing and how the individual behavior may affect the performance and dynamic ...
-
(Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1984)The importance of problems related to machines operating at partial flow rate led to Societe Hydrotechnique de France (S.H.F.) to form a working group on the subject. In order to better understand partial flow phenomena ...
-
(Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1990)Pulsation dampeners are frequently used to reduce piping pressure pulsations and vibrations in reciprocating pump systems. Despite their extensive use, scientific understanding of how the dampeners work and what design ...
-
(Texas A&M University. Turbomachinery Laboratories, 2013)An investigation of the effectiveness of online combustion turbine axial compressor washing using various purity grade waters and commercial washing detergents was performed. For this project, blade surface fouling dirt ...
-
(Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1995)The suction-impeller (single-suction) of a 33,500hp, four-stage barrel pump used in boiler feed service at a fossil fuel steam plant experienced operating life ranging from 6.0 to 19 months. Cavitation erosion on the suction ...
-

(Texas A&M University. Turbomachinery Laboratories, 2004)
-
(Texas A&M University. Turbomachinery Laboratories, 1996)Recently, several recommendations have been proclaimed concerning limitations of the maximums suction specific speeds (n85) of centrifugal pumps. These recommendations result from statistical evaluations of pump failures ...
-
(Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1985)A series of right-angle pump intakes, incorporating minimum axial depths and decelerating flows, has been experimentally evaluated using an air flow test procedure. Performance was measured, internal flow fields observed ...
-
(Texas A&M University. Turbomachinery Laboratories, 1997)In today's competitive business environment, one is constantly called upon to make decisions that directly influence operations, and, therefore, profitability. In recent years, it has been necessary to evaluate not just ...
-
(Turbomachinery Laboratories, Texas A&M Engineering Experiment Station, 2015)Flexible sealing elements, typically elastomeric O-rings are commonly used to contain fluids within pressurized cavities of turbomachinery at the interfaces between adjoining components. All too often the only selection ...
