Title (EN) DRY GAS SEAL COOLING ARRANGEMENT AND METHOD
(FR) CONFIGURATION ET PROCÉDÉ DE REFROIDISSEMENT DE JOINT ÉTANCHE AUX GAZ SECS
Abstract:
(EN) The shaft seal arrangement for a rotating turbomachine shaft having a rotation axis, comprises a rotor part (41) and a stationary part (43). Adry gas seal (45) is further provided, in combination with a cooling fluid volume (67) arranged for receiving a cooling fluid and in heat exchange relationship with the dry gas seal. A venting arrangement collectively vents exhaust cooling fluid and dry sealing gas from the shaft seal arrangement.
(FR) La présente invention concerne une configuration d'étanchéité d'arbre pour un arbre de turbomachine rotative possédant un axe de rotation, comprenant une partie rotor (41) et une partie fixe (43). L'invention concerne également un joint étanche aux gaz secs (45) en combinaison avec un volume de fluide de refroidissement (67) agencé pour recevoir un fluide de refroidissement et en relation d'échange thermique avec ledit joint étanche aux gaz secs. Une configuration de ventilation évacue collectivement le fluide de refroidissement d'échappement et les gaz d'étanchéité secs de ladite configuration d'étanchéité d'arbre.
