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 ...
