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.
