Abstract: | Vibration monitoring is one of the traditional and classic ways of machine condition determination. It is applied not only to the monitoring of stationary structures, but has found its place even when detecting the condition of the rotating parts. This paper attempts to describe some of the key components of rotating machines, their defects and the actual development of methods for detection and specification of their failures. Current knowledge and capabilities of sensing and computing technology allow an early and accurate detection of a number of failures. In several cases, the component monitoring has recently reached a form of automated procedures that are deployed for long-term turbine monitoring and are introduced into machine control system. The components such as rotor, rotating blades and rotor seals are the key components covered by this paper. The compiled survey includes the rotor/stator contact identification methods, the indirect monitoring of the rotating blades vibration and the subsequent influence on rotor vibration. Last but not least, an approach of identifying the properties of rotor seals is discussed, which significantly contribute to the formation of the dynamic behavior of the rotor system as a whole. |
