Abstract

L'invention concerne un module de turbomachine d'axe longitudinal X, comprenant : - un arbre rotatif (2) autour de l'axe longitudinal X par rapport à une partie fixe (2) de la turbomachine (1) et apte à générer des vibrations de la turbomachine, - un palier de guidage (10, 10', 10", 11, 11', 11") en rotation de l'arbre rotatif, le palier de guidage comprenant un film fluide d'amortissement (19) emprisonné dans une chambre d'amortissement (20) annulaire située radialement entre une bague extérieure (14) du palier de guidage et la partie fixe (12) de la turbomachine, - un circuit d'alimentation (25) en fluide sous pression du film fluide d'amortissement dans la chambre d'amortissement, - un système de régulation de la pression comprenant un dispositif électronique de commande (31) et un capteur de vibration (33, 34) qui est relié au dispositif électronique de commande (31) et qui est adapté pour mesurer une amplitude des vibrations de la turbomachine, Selon l'invention, le système de régulation est configuré de manière à réguler la pression d'alimentation du film fluide d'amortissement du palier de guidage lorsque l'amplitude des vibrations mesurée est supérieure ou égale à une valeur seuil de vibration.The invention relates to a turbomachine module with a longitudinal axis X, comprising: - a rotary shaft (2) around the longitudinal axis X with respect to a fixed part (2) of the turbomachine (1) and capable of generating vibrations of the turbomachine, - a guide bearing (10, 10 ', 10 ", 11, 11', 11") in rotation of the rotary shaft, the guide bearing comprising a fluid damping film (19) trapped in an annular damping chamber (20) located radially between an outer ring (14) of the guide bearing and the fixed part (12) of the turbomachine, - a supply circuit (25) of pressurized fluid to the fluid film damping in the damping chamber, - a pressure regulation system comprising an electronic control device (31) and a vibration sensor (33, 34) which is connected to the electronic control device (31) and which is suitable for measuring an amplitude of the vibrations of the turbomachine, According to the invention, the control system ulation is configured so as to regulate the feed pressure of the fluid damping film of the guide bearing when the measured vibration amplitude is greater than or equal to a vibration threshold value.
