Improve Turbomachinery Reliability by Taking Corrective Procedures

Age old problems of unbalance, distortion, misalignment, critical speed, looseness and vibration due to stator-rotor contact still head the list as major causes of turbomachinery outages. Here is what to look for, where to measure, and what to do.

High speed turbomachinery is inherently reliable, having few moving parts, but on occasion, even these machines break down. However, if units are properly installed, maintained and operated, service interruptions can be minimized. Problems arising in the field during operation of high speed turbomachinery, as well as their causes, are identified and the solutions are discussed in the attached article.
