Motion Amplification: A New Way to Visualize Vibrations
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2018)
Motion Amplification utilizes a camera to turn each pixel into a displacement sensor capable of measuring vibrations and amplifying them to a level visible to the eye. This capability lends itself to an advanced troubleshooting ...
High Performance Coupling and Rotating Machines
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2018)
This course covers the design and application of high performance couplings and rotating machines. Initially the Turbomachinery driver and driven machines are analyzed together with their characteristics and how they affect ...
BB1 Lateral Dynamic Analysis
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2018)
Customer has four 4x8x13 BB1 booster pumps for produced water injection. One pump was recently repaired and ran for only 4 months. Typically these pumps run about 16-18 months. Before shutting down the pump it had a high ...
Structural Natural Frequency Tuning on a Vertical Pump
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2018)
This case study demonstrates the steps taken to solve a structural resonance issue on a VFD driven vertical pump installed in the field. Topics discussed include problem validation, steps taken to solve the issue, the ...
Predicting, Understanding and Avoiding the Ekofisk Rotor Instability Forty Years Later
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2018)
This famous machine is re-examined to assess how well (or not) current design and analytical methods have evolved to avoid shaft whip instability. In addition to reviewing the compressors history and design evolution, the ...
TL07 - Direct Head Measurments for Turbomachinery Design
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, [2019])
The isentropic head is one of the most important physical properties for the design and testing of compressors and turbines. It is a critical parameter for the determination of machinery work and power from test data and ...
TL08 - Addressing High-Subsynchronous Vibrations in a Turboexpander Equipped with Active Magnetic Bearings
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, [2019])
This paper presents the experience of the authors with a turboexpander (TEX) equipped with active magnetic bearings (AMBs) in a natural gas processing facility. The TEX was unable to achieve design performance due to high ...
