Abstract

POMPE DESTINEE A FAIRE PASSER DES LIQUIDES D'UN ESPACE MAINTENU SOUS VIDE DANS UN ESPACE OU LA PRESSION EST PLUS ELEVEE, COMPORTANT UN CORPS DE POMPE AUQUEL SE RACCORDE SENSIBLEMENT TANGENTIELLEMENT UNE TUBULURE DE PRESSION, UNE ROUE DE POMPE OU ROTOR MONTEE ROTATIVE DANS LE CORPS DE POMPE, A LAQUELLE LE LIQUIDE ARRIVE AXIALEMENT PAR UNE TUBULURE D'ADMISSION, ET DES ORGANES DE REFOULEMENT DISPOSES SUR LA ROUE DE POMPE ET S'ETENDANT ENTRE LADITE ROUE ET LA PAROI DU CORPS DE POMPE. CHAQUE ORGANE DE REFOULEMENT SE PRESENTE SOUS LA FORME D'UN SIPHON RELIE DE FACON ETANCHE A LA CHAMBRE D'ASPIRATION 11 DE LA ROUE DE POMPE 7 COMPORTANT UN CANAL DE REFOULEMENT 10 QUI, DANS UN PREMIER TEMPS, DIRIGE LE LIQUIDE VERS L'EXTERIEUR PUIS LE RENVOIE VERS L'INTERIEUR A UNE OUVERTURE DE SORTIE 15, ET LA CHAMBRE D'ASPIRATION 11 DE LA ROUE DE POMPE 7 EST RELIEE AU COUSSIN DE GAZ DE LA CHAMBRE A VIDE 1 ET EST RENDUE ETANCHE PAR RAPPORT AUX PARTIES NON ROTATIVES DU CORPS DE POMPE.
