摘要
The arrangement for monitoring rubbing between a rotary part and a stationary part in a rotating turbomachine comprises: at least one mechanical oscillations detector (11 12 13) for measuring mechanical oscillations at least one point of the turbomachine at least one particles detector (21) for measuring debris passing in at least one section of a flow path of the turbomachine and an electronic monitoring unit (50) electrically or electromagnetically connected to the oscillations detector and the particles detector (21) and arranged to acquire and process signals generated by the oscillations detector and the particles detector; the electronic monitoring unit (50) uses the oscillations measurement primarily for estimating presence of rubbing and the debris measurement primarily for estimating severity of rubbing.
