What is Understanding Subsynchronous Vibration in Compressors about?
The document discusses experiences with nonsynchronous forced vibration in centrifugal compressors. It describes the differences between self-excited vibrations, which are shaft instability issues, and forced vibrations, which are caused by flow instabilities like stage stall. Forced vibrations occur at lower frequencies determined by the acoustic response of the system and piping. Symptoms of forced vibrations include low-frequency piping vibrations, pulsations, and subsynchronous shaft vibrations. Case st
