Large Vibrations on Centrifugal Compressor Caused by Inappropriate Operation During Mechanical Running Test
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2018)
During the mechanical test of a centrifugal compressor, the rotor experienced a sudden increase of the radial vibrations. After re-start, the compressor showed unacceptably high vibrations.
The RCA revealed: The vibrations ...
Accurate Estimation of Start-Up Pulsating Torque of Direct On Line Synchronous Motors Driving Compressor Trains
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2018)
In a compressor train driven by fixed speed synchronous motor (>17MW) was discovered a potential torsional problem on the input shaft of the hydraulic variable speed gear during the start-up phase when only low speed shaft ...
Gear Box Bull Gear High Vibration due to Fluid Instability and Analytical Evaluation of New Bearing Design
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2018)
Three shaft Gear Box upgraded to meet Screw compressor model upgrade. Gear Box was installed, as a part of compressor upgrade project, with Bentley Nevada 3500 Shaft vibration protection facility and observed trip on ...
Unexpected Vibrations in Gearbox Caused by System Integration Issues
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2018)
This case study deals with a 24MW turbo-compressor unit composed of a gas turbine, a speed reduction gearbox with a lube oil pump mounted on its low speed shaft and two compressors in series. The unit was subject to high ...
