Abstract

JOINT HYDROSTATIQUE DESTINE A ASSURER L'ETANCHEITE ENTRE MILIEUX DANS LESQUELS LES PRESSIONS SONT TRES DIFFERENTES. CE JOINT COMPORTE LE LOGEMENT TUBULAIRE 20 D'UNE DOUILLE FLOTTANTE 18 DONT IL EST SEPARE PAR UN PREMIER INTERVALLE 25 DANS LEQUEL UN FLUIDE EPURATIF SOUS PRESSION EQUILIBRE CELLE DE CETTE DOUILLE, DONT IL TRAVERSE LA PAROI PAR DES TROUS RAYONNANTS 30. CETTE DERNIERE 18 CONTIENT UNE GARNITURE TUBULAIRE 16 DONT ELLE EST SEPAREE PAR UN SECOND INTERVALLE 17 ET QUI ENTOURE UN ARBRE ROTATIF 12 DONT ELLE EST SOLIDAIRE ET AVEC LEQUEL ELLE TOURNE. A L'UNE 21 DES EXTREMITES DE L'INTERVALLE 17, LE FLUIDE ASSURE L'ETANCHEITE DU JOINT DONT IL SORT PAR L'AUTRE EXTREMITE 23 DE L'INTERVALLE 17 POUR ETRE FILTRE, ET REMIS SOUS PRESSION ET RENVOYE DANS LE JOINT PAR DES TROUS 32 PERCES DANS LA PAROI DU LOGEMENT20. APPLICATION NOTAMMENT AUX POMPES CENTRIFUGES.
