Sealing unit for water turbine running wheel - is hermetically closed and impedes oil ingress in chamber of blade rotating mechanism

The running wheel in a water turbine comprises a hub (1) with blades (2), and has a hollow chamber (5) to take a servo unit (3) and another chamber (6) accommodating a blade rotating mechanism (4). In a section where a piston connecting rod (9) passes through a hole in an intermediary wall (7), is p...

Zusammenfassung:	The running wheel in a water turbine comprises a hub (1) with blades (2), and has a hollow chamber (5) to take a servo unit (3) and another chamber (6) accommodating a blade rotating mechanism (4). In a section where a piston connecting rod (9) passes through a hole in an intermediary wall (7), is provided a hermetically closed sealing unit (18) which prevents oil entry into the blade rotation mechanism chamber (6). Slide surfaces in the blade rotating mechanism links are of self-lubricating material. The turbine is usable where the drop height of water does not exceed 80 metres. LA PRESENTE INVENTION SE RAPPORTE AU DOMAINE DES CONSTRUCTIONS HYDRO-MECANIQUES.LA ROUE DE TURBINE HYDRAULIQUE A PALES ORIENTABLES COMPREND UN MOYEU 1 MUNI DE PALES 2, ET COMPORTANT UNE CHAMBRE 5 DE LOGEMENT D'UN SERVO-MOTEUR 3 ET UNE CHAMBRE 6 POUR LE LOGEMENT D'UN MECANISME 4 D'ORIENTATION DES PALES 2. IL EST PREVU DANS LA ZONE DE PASSAGE D'UNE TIGE 9 A TRAVERS L'ORIFICE 7 D'UNE CLOISON 7 SEPARANT LA CHAMBRE 5 DE LA CHAINE 6, UN DISPOSITIF D'ETANCHEITE 18, CE QUI EMPECHE LA PENETRATION DE L'HUILE DANS LA CHAMBRE 6 DU MECANISME 4 D'ORIENTATION DES PALES 2. LES SURFACES FROTTANTES DES ELEMENTS DU MECANISME 4 D'ORIENTATION DES PALES 2 SONT REALISEES EN MATIERE AUTOLUBRIFIANTE.L'INVENTION S'APPLIQUE PLUS PARTICULIEREMENT AUX TURBINES HYDRAULIQUES FONCTIONNANT SOUS DES PRESSIONS D'EAU ALLANT JUSQU'A 80 METRES.
