Abstract :
Vibrations are common phenomenon in the rotating machinery, which
could carry important information about condition of the rotating
machinery. All specific failures in rotating machinery have their own
characteristics of the vibrations. By measuring and analysis of vibrations
cause of increased vibrations could be determined. Since misalignment and
rotating looseness have similar frequency spectrum characteristics, it is
difficult to determine which one of the failures is present. When cause of
increased vibrations is determined, it is possible to plan the future steps for
the repairing and neutralising present cause of the possible failure.
Process of vibration analysis followed by present cause of increased
vibration in rotating machinery repairing is presented in this paper through
example on the ventilation system for smoke drain in the thermal power
plant.
