-
(Texas A&M University. Turbomachinery Laboratories, 1998)This lecture discusses how the vibration characteristics and eccentricity measurements were combined with rotordynamic analyses to help improve the reliability of a turbine generator unit. It also explains certain ...
-
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station; Texas A & M University. Libraries; Texas A & M University. Libraries, 2020)This case study discusses the impeller redesign of 10 8x15 BB1 two stages Amine pump in a Gas Sweeting Plant in Malaysia. The original pump was supplied in 1996 and after some design changes it had an history of recurring ...
-
(Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1989)Analytical and experimental assessments of the vibration characteristics are described for two 700 hp, vertically mounted centrifugal service water pumps following their conversion from fixed speed to variable speed ...
-
(Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1989)The Heber Project is a demonstration power plant which operates on a binary cycle using a geothermal heat source. It has four booster pumps in the hydrocarbon working fluid circuit. These pumps have had a long history of ...

Vibration Field Problem Resolved with Analytical Diagnostic Approach and Innovative Impeller Design (Turbomachinery Laboratory, Texas A&M Engineering Experiment Station; Texas A & M University. Libraries, 2022)Several pumps of same design exhibited field vibrations above API limits, dominated by Vane Passage Frequency (VPF). Root cause analysis included both experimental and theoretical paths.Experimental investigation , with ...
-
(Texas A&M University. Turbomachinery Laboratories, 1990)The overall concept of vibration monitoring is presented based upon theory and the practical constraints of machinery construction, transducer characteristics and the cost/benefit ratio of available systems. General features ...
-
(Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1987)Recent efforts to develop and implement techniques to monitor and diagnose problems in submerged vertical shaft pumps are summarized. Projects based on iterative analytical and experimental efforts were implemented on ...

-
(Texas A&M University. Gas Turbine Laboratories, 1980)A large vertical pump with its associated motor driver constitutes a very complex dynamic system. The apparent simplicity of the visible cantilever portion of the machine belies the complex interaction of the unit with its ...
-
(Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1993)A case history is presented in which vibration related problems with two pole electric motors have delayed acceptance of the complete pump packages by the end user. Noncompliance with contract specifications led to a major ...
-
(Texas A&M University. Turbomachinery Laboratories, 1997)Large utility steam turbines have experienced very high vibration levels on their generator exciter bearings. Units where the exciter rotor is supported by a single bearing are particularly susceptible. This synchronous ...
