-
(Turbomachinery Laboratories, Texas A&M Engineering Experiment Station, 2014)The paper discusses and highlights the most prominent critical pump related challenges and experiences Eskom has been faced with during the past 20 years. The challenges include the following: The effects of Pump System ...
-
(Texas A&M University. Turbomachinery Laboratories, 1989)The design and application of solid couplings combined with flexible quill shafts for high speed turbocompressors are presented. Solid couplings are rigid in the axial direction. They transmit any residual thrust from one ...

(Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1985)
-
(Texas A&M University. Turbomachinery Laboratories, 1988)Experience, theoretical and practical, investigations are presented on two radial flow high-speed turbines, which showed unacceptable high subsynchronous vibrations during operation onsite. The first example deals with a ...
-
(Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1991)An output was increased on the Eat-West crude oil pipeline in Saudi Arabia, increasing shaft seal failures were encountered. These limited the operation of the pipeline. Surveys on site and detailed model tests with flow ...

-
Solutions To Abrasive Wear-Related Rotordynamic Instability Problems On Prudhoe Bay Injection Pumps (Turbomachinery Laboratories, Department of Mechanical Engineering, Texas A&M University, 1988)Prudhoe Bay produced water injection pumps suffered serious vibration problems and high balance piston leakage a few months after initial startup. Even though initial pump orientation at low water rates was satisfactory, ...
-
(Texas A&M University. Turbomachinery Laboratories, 1999)Operating and maintaining key rotating equipment in a petrochemical service and tight economic constraints requires an indepth evaluation in performance deterioration of key gas turbines and axial flow compressor parameters. ...
-
(Turbomachinery Laboratories, Texas A&M Engineering Experiment Station, 2016)A solution was developed for an extreme discharge piping vibration problem on an 80 hp gear pump piping system. Maximum field-measured vibration levels were over 4 ips 0-pk (200 mm/sec pk-pk). Most gear pumps are not ...
-
(Turbomachinery Laboratories, Texas A&M Engineering Experiment Station, 2016)Specific Problem: Crude oil pump piping system that had previously operated without problems experienced a failure resulting in a release of oil: Vibration increased when a new well was opened and the fluid properties ...
-
(Texas A&M University. Turbomachinery Laboratories, 2003)A new cogeneration installation was in the process of being commissioned when severe subsynchronous vibration was detected on the generator during no load tests. Subsequently, two rotordynamics problems were discovered. ...
