Title (EN) MECHANICAL SEAL
(FR) JOINT D'ETANCHEITE MECANIQUE
Abstract:
(EN) A mechanical seal comprises a first elastomeric annular member (22) to urge a first (stationary) seal ring (16) mounted on a first seal ring holder (17) into sealing engagement with a second (rotary) seal ring (13) mounted on a second seal ring holder (10) attached to a shaft (11) passing into a pressure vessel. A second elastomeric annular member (19) isolates the first elastomeric annular member (22) from the internal pressure and contents of the pressure vessel.
(FR) Joint d'étanchéité mécanique comprenant un premier élément (22) élastomère annulaire destiné à amener un premier anneau (16) d'étanchéité (fixe), monté sur un premier support (17) d'anneau d'étanchéité, en contact d'étanchéité avec un second anneau (13) d'étanchéité (rotatif) monté sur un second support (10) d'anneau d'étanchéité, fixé à un arbre (11) passant dans un récipient sous pression. Un second élément (19) élastomère annulaire isole le premier élément (22) élastomère annulaire de la pression interne et du contenu du récipient sous pression.
