absolute and relative vibration - Opis:
- The paper presents the research results of machine condition monitoring and fault diagnostics of the High Power Steam Turbines and Electric Generator rotating system. The inconsistencies of journal bearings absolute vibration parameters of the rotating system and journal bearings shafts relative vibration parameters have been shown. In the low frequency range the shafts relative vi-bration displacements are decisive informative in defects diagnostics. The journal bearings sup-ports absolute vibration velocities of low frequencies are being strongly damped by massive bear-ings supports, etc. Journal bearings absolute vibration parameters supply the information errone-ously attributed to the rotor. High frequency absolute vibration acceleration, however, make it possible to provide monitoring of coupling.
