Title (EN) TURBOMACHINE AND CORRESPONDING METHOD OF ASSEMBLING A FACE SEAL ASSEMBLY
(FR) TURBOMACHINE ET PROCÉDÉ CORRESPONDANT D'ASSEMBLAGE D'UN ENSEMBLE DE DISPOSITIF D'ÉTANCHÉITÉ DE FACIALE
Abstract:
(EN) A turbomachine (36) and a method of assembling a face seal assembly (102) are disclosed. The turbomachine (36) includes a stator (39), a rotor (40), and a face seal assembly (102) including first and second segmented seal rings (114, 116). The first segmented seal ring (114) includes a plurality of joints (152) and a first flat- contact surface (160) and the second segmented seal ring (116) includes a plurality of segment ends (164) and a second flat-contact surface (166). The second segmented seal ring (116) is coupled to the first segmented seal ring (114) such that the second flat-contact surface (166) is in contact with the first flat-contact surface (160). The plurality of segment ends (164) is circumferentially offset from the plurality of joints (152). The first segmented seal ring (114) is slidably coupled to the stator (39) and defines a face seal clearance (104) between the rotor (40) and a seal bearing face (132).
(FR) L'invention porte sur une turbomachine (36) et sur un procédé d'assemblage d'un ensemble dispositif d'étanchéité faciale (102). La turbomachine (36) comprend un stator (39), un rotor (40) et un ensemble dispositif d'étanchéité faciale (102) comprenant des première et seconde bagues d'étanchéité segmentées (114, 116). La première bague d'étanchéité segmentée (114) comprend une pluralité de joints (152) et une première surface de contact plate (160) et la seconde bague d'étanchéité segmentée (116) comprend une pluralité d'extrémités de segment (164) et une seconde surface de contact plate (166). La seconde bague d'étanchéité segmentée (116) est accouplée à la première bague d'étanchéité segmentée (114) de sorte que la seconde surface de contact plate (166) soit en contact avec la première surface de contact plate (160). La pluralité d'extrémités de segment (164) est décalée de manière circonférentielle par rapport à la pluralité de joints (152). La première bague d'étanchéité segmentée (114) est accouplée de manière coulissante au stator (39) et définit un jeu d'étanchéité faciale (104) entre le rotor (40) et une face d'appui d'étanchéité (132).
