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 ...
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)
Pine Bend, MN, 12x10, 9 stage vertical can pump, 600 hp, 1780 rpm
A new smaller, higher efficiency motor was installed to replace the old motor and shortly after numerous mechanical seal failures occurred. The motor ...

Leakage and Force Coefficients for Pump Annular Seals Operating With Air/Oil Mixtures: Measurements Vs Predictions and Air Injection to Increase Seal Dynamic Stiffness
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2018)
The lecture presents measurements of leakage and dynamic force coefficients for six annular seals operating with an air in oil mixture ranging from pure liquid to just air. Each seal has a distinct clearance configuration: ...
Design and Verification Testing Of Balance Piston for High-Viscosity Multiphase Pumps
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2018)
OneSubsea was awarded a project involving the development and testing of a HighBoost multiphase pump for boosting unprocessed multiphase well streams with liquid viscosities up to 800 centipoise (cP). The viscosity requirement ...
A Robust Algorithm to Detect Multiple Centrifugal Pump Faults with Corrupted Vibration and Current Signatures Using Continuous Wavelet Transform
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2018)
Centrifugal pumps are susceptible to seizures owing to reasons such as, fluid flow abnormalities and/or mechanical component failures. Consequently, it is crucial to recognize these faults and estimate their severity. The ...
