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 ...
Successful 2 planes balancing confirm by rotordynamics calculation
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2020)
This historical case is focus on the vibration behavior of a generator. After a short circuit issue on the grid, the machine train trip. At this time the level of vibration of the generator was acceptable and well below ...
Lube Oil Carbonisation
(Turbomachinery Laboratory, Texas A&M Engineering Experiment Station, 2020)
Carbonized particles can get deposited in housing oil seal clearances causing a partial rub like phenomenon. Friction caused due to reduced clearances because of accumulation of carbonized particles leads to shaft thermal ...
