Title (EN) ANNULAR ELASTOMERIC SLURRY SEAL
(FR) JOINT ANNULAIRE ELASTOMERE D'ETANCHEITE AUX BOUES
Abstract:
(EN) A rotary mechanical seal for a rotating shaft passing into a pressure vessel, the seal having stationary and rotating seal rings (12) with at least one of the rings (12) supported in an axially biased holder (9), characterised by an elastomeric annular member (11) held in a groove, which groove is so designed as to obviate clogging or crystallising in the gap between the seal face holder (9) and the housing (10). Preferably, the groove has a protrusion located on its outer edge which has sloped inner and outer faces to co-operate with the annular elastomeric member (11) so that the member (11) protrudes past or is flush with the edge.
(FR) Joint rotatif mécanique destiné à un arbre tournant passant dans un récipient de pression, le joint d'étanchéité étant pourvu d'anneaux (12) d'étanchéité stationnaires et tournants, au moins un des anneaux (12) étant supporté par un support (9) sollicité axialement, caractérisé par un élément (11) élastomère annulaire maintenu dans une gorge, ladite gorge étant conçue de manière à éviter l'obstruction ou la cristallisation dans l'interstice situé entre le support (9) de la face du joint d'étanchéité et le logement (10). La gorge est de préférence pourvue d'une saillie située sur son bord extérieur, lequel est muni de faces intérieure et extérieure en déclive, fonctionnant conjointement avec l'élément (11) annulaire élastomère, de sorte que l'élément (11) dépasse le bord ou est de niveau avec ce dernier.
