Abstract

CIRCUIT DE REFROIDISSEMENT PAR LIQUIDE DES AUBES D'UNE TURBINE. IL COMPORTE, DANS LE PIED DE CHAQUE AUBE, ENTRE UN RESERVOIR A FLUIDE DE REFROIDISSEMENT ET CHACUN DES CONDUITS 30 QUI ALIMENTENT INDIVIDUELLEMENT LES CANAUX DE REFROIDISSEMENT DE LA PALE DE L'AUBE, UN JOINT D'ETANCHEITE A SIPHON 40 QUI COMPORTE UN EVIDEMENT ANNULAIRE 52 DANS LEQUEL EST MONTEE UNE PIECE RAPPORTEE 50 QUI COMPORTE UNE SERIE DE RAINURES AXIALES 54 DANS SA PERIPHERIE EXTERIEURE ET UN EVIDEMENT CENTRAL 56 DANS SON DESSUS DANS LEQUEL PENETRE UN PROLONGEMENT 58 DU CONDUIT 30 POUR FORMER AINSI UNE SERIE DE SIPHONS EN S QUI PERMETTENT LE PASSAGE DU LIQUIDE MAIS EMPECHENT CELUI DE LA VAPEUR. APPLICATION AUX CIRCUITS DE REFROIDISSEMENT PAR LIQUIDE EN CIRCUIT OUVERT DES TURBINES.
