Case Study: Lateral Analysis Fixes a Multi-Stage Diffuser Boiler Feedwater Pump
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2020)
History gets confusing. A lot of emails, vibration reports, and attempted fixes over the years. Customer spent 3 years working closely with OEM, Pump was shipped back to OEM for additional testing. OEM design suggestions ...
Detection of Misalignment from Vibration Data
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2020)
On a boiler feed pump driven by a motor running close to 3600 rpm, a horizontal misalignment issue was suspected by examining orbit plots besides shaft centerline plots. The follow-up inspection did uncover large parallel ...
An End-User’s Guide to Centrifugal Pump Rotordynamics
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2020)
This tutorial discusses concepts and methods involved in performing and evaluating centrifugal pump rotordynamic analysis. The presentation includes Lomakin Effect, Gyroscopic Effect, Cross-Coupling, Rotordynamic Stability, ...
How to Specify, Design, and Install Canned Motor Pumps in a Refinery
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2020)
This tutorial will guide the end user through the process of specifying and installing canned motor pumps in refinery services. Specific examples will be shown of both successes and failures and lessons learned will be discussed.
INFLUENCE OF THE SHAPE OF THE IMPELLER BLADE TRAILING EDGE ON SINGLE AND TWO-PHASE AIRWATER FLOWS IN A CENTRIFUGAL PUMP
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2020)
In this study, the performance of a radial-type centrifugal pump was investigated for different single and two-phase flow conditions to evaluate the influence of the shape of the impeller blade trailing edge. For that ...
What’s inside the ‘Box’ When Considering API Piping Plan 54?
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2020)
What could typically drive support system selection towards Plan 54?A Plan 54 support system designation may be selected as it has specific advantages over Plan 53A, B, and C. The primary difference is that the circulation ...
Benefits of Physical Modeling in Large Pump Station Design
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2020)
This presentation explores common problems with pumps and pump stations, issues with pump intake hydraulics, HI standards, physical modeling – key considerations and presents the case study of Dallas Elm Fork WTP Pump Station 1.
Excessive Axial Load on Main Oil Line Pump Thrust Bearing, Measurement and Control
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2020)
This case study describes the deployment of an axial load measurement and control solution for centrifugal pumps experiencing high bearing temperatures on the Non-Drive End (NDE). Through the real-time measurement of the ...
Video Based Vibration: A tutorial and case study with a live demonstration and data analysis on real life pump data
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2020)
Recent advances in camera technology allows the user to detect subtle motion and amplify that motion to a level visible with the naked eye. Furthermore displacements, phase and frequency of motions can all be determined ...
Balancing three-bearing rotors
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2020)
Multistage cryogenic pump rotors are vertically oriented and supported radially by three bearings. However, while the rotors are oriented vertically and supported in three planes, they are balanced horizontally in two-plane ...
