Abstract

L'invention concerne un agencement d'étanchéité pour un arbre rotatif. Un joint mécanique et une douille d'étranglement sont montés dans un carter de pompe ayant une chambre de fluide de travail et une région d'extrémité. Un arbre est monté à rotation dans le carter de pompe. Le joint présente une partie stationnaire montée sur le carter de pompe, et une partie rotative montée sur l'arbre. Une douille d'étranglement entoure l'arbre et est connectée au carter. La douille d'étranglement présente une surface interne qui fournit un passage de fluide entre la surface interne de la douille d'étranglement et l'arbre. La douille d'étranglement est espacée le long de l'arbre à une distance axiale du joint mécanique, en formant ainsi un espace de fluide barrière. Le joint mécanique sépare l'espace de fluide barrière de la chambre de fluide de travail. Le fluide barrière migre au-delà de la surface interne de la douille d'étranglement, lubrifie les paliers et les engrenages de la pompe, et est recueilli en vue de sa réutilisation.
