Large centrifugal compressors that are utilized in the process of producing compressed gases or liquid nitrogen, oxygen and argon are located all over the world. There are thousands of these large compressors in operation. These machines are unique in design and thus have some interesting problems. This paper presents some case histories of problems that can occur in this category of rotating equipment. These cases illustrate how advanced analysis equipment can be utilized to capture amplitude and phase deviations, compressor surge and torsional responses from both start up transients and the torsional magnetic pole slip stimulus from synchronous motors.
