Abstract:
An empirical investigation is undertaken in order to assess the potential of the
AE technique for the detection of seal-to-rotor rubbing in steam turbines.
Rubbing was induced at various axial locations along a 4 ½ tonne test rotor,
rotating at 3000 rpm and supported by 7” (178mm) journal bearings. This paper
examines the capabilities of bearing mounted AE transducers for the detection of
seal-torotor rubbi
