Abstract
CETTE POMPE CENTRIFUGE A AUTO-AMORCAGE SE COMPOSE D'AU MOINS UNE CELLULE CENTRIFUGE EXPOSEE A L'ADMISSION TOTALE ET COMPORTANT UN ARBRE HORIZONTAL, ET D'UNE CELLULE DE PURGE D'AIR CALEE SUR LE MEME ARBRE EN DEHORS DU COURANT DE CIRCULATION PRINCIPAL, CONSTRUITE A LA MANIERE D'UNE POMPE A CANAL LATERAL OU A ANNEAU LIQUIDE. POUR ASSURER UN REFROIDISSEMENT DE LA CELLULE DE PURGE D'AIR, LE COTE ASPIRATION DE CELLE-CI EST RACCORDE, NON SEULEMENT A LA ZONE DANS LAQUELLE LES GAZ A ELIMINER ONT TENDANCE A S'ACCUMULER DU COTE ASPIRATION DE LA CELLULE CENTRIFUGE EXPOSEE A L'ADMISSION TOTALE, MAIS AUSSI A UNE ZONE DE LA POMPE DU COTE REFOULEMENT, DE SORTE QU'IL S'ETABLISSE EN SERVICE NORMAL UN COURANT DE LIQUIDE DE REFROIDISSEMENT QUI PASSE EN REGARD DE L'ORIFICE D'ASPIRATION DE LA CELLULE DE PURGE D'AIR.
