Measurements and Analysis of High Machine Vibration - A case Study of Screw Compressor Rub
Abstract
Case Study 21: This case study concerns a screw compressor operating in offshore process environment with unpredictable gas composition. The compressor was tripped on high vibration during startup after seals replacement. Analysis of the acquired transient vibration data indicated rub as secondary cause of the high vibration, and improper timing gears assembly as a root cause. Shop inspections confirmed rub between male and female rotors. Implemented recommendations ensured timely return of the compressor to service, and lessons learned prevented repeat occurrence on similar machines.
