Abstract

Fremgangsmåte for deteksjon av rubbing mellom en turbomaskins (1) stator (2) og rotor (4) hvor en giver (16, 18) i form av et akselaerometer, en sensor for måling av vibrasjon ved ultrahøye frekvenser eller en mikrofon anbringes ved turbomaskinen (1), hvoretter signalet fra giveren (16, 18) i det minste frekvens- eller amplitudeanalyseres og sammenlignes med i det minste forutbestemte eller adaptive verdier fra gruppen som omfatter måleverdier og frekvensmønstre, og hvor det ut fra den nevnte sammenligning og forutbestemte grenseverdier bestemmes om rubbing er til stede eller har vært til stede.A method of detecting rubbing between a turbo machine (1) stator (2) and rotor (4) wherein an encoder (16, 18) in the form of a shaft aerometer, an ultra-high frequency vibration sensor or a microphone is applied to the turbo machine ( 1), after which the signal from the transducer (16, 18) is at least frequency or amplitude analyzed and compared with at least predetermined or adaptive values from the group comprising measurement values and frequency patterns, and where, based on said comparison and predetermined limit values, it is determined rubbing is present or has been present.
