Resolving High Vibration On a Vertical Pump
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2018)
High vibration were observed on the motor, pump,structure for more than 2 years with 1X dominant motor vibration. Assuming that the issue is of complete structural issue even though this motor was running well in the past, ...
Vertical Turbine Pump Reliability Improvement
(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 ...
Field Performance Testing Centrifugal and Reciprocating Compressors
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2018)
Field performance testing is often necessary to verify guaranteed as-installed aerodynamic and mechanical performance of new machinery. It can also be used to monitor long-term machinery performance, track degradation ...
Centrifugal Compressors 201
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2018)
This course supplements the Centrifugal Compressor 101 course by covering in greater detail four key areas related to compressors: aerodynamics, rotordynamics, performance and mechanical testing, and surge control. It is ...
Use of Motion Amplified Video to Diagnose Pump Vibration
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2018)
Use of Operating Deflection Shapes (ODS) has become an accepted method for understanding and diagnosing pump and other turbomachinery vibration problems. However, data acquisition can take a long period of time, and requires ...
Fundamentals of Mechanical Seals
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2018)
This short course is designed for all personnel that interacts with mechanical seals such as engineers, users, installers, purchasers, reliability engineers, and other industrial plant functions. It starts with basic ...
Up-thrust and Seal Failures on a Vertical Can Pump
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2018)
