We have a Gas Turbine Driven Compressor Train. Gas Turbine has dual shafts i.e. Gas Producer Rotor and Power Turbine Rotor. We are observing increase in vibration levels between startup cycles. APHT Plots indicate vibration levels of around 20 microns with phase angle of 150 Degrees for one start up cycle. After another startup, vibration levels increase to around 40 Microns with Phase angle of 220 Degrees. Phase angle changes from 150 deg to 220 deg and back. Orbit Plots are circular and...Read More...
