Abstract

La présente invention concerne un ensemble de pompes à amorçage automatique qui représente un montage en série d'une pompe à anneau liquide fonctionnant comme une pompe volumétrique rotative et d'une pompe centrifuge à amorçage normal. Dans un boîtier équipé d'une ouverture d'admission et d'un tuyau de refoulement, la pompe centrifuge présente un arbre monté de manière rotative avec une roue. Une chambre intérieure délimitée par une enveloppe de boîtier de la pompe volumétrique est raccordée à une chambre intérieure côté aspiration de la pompe centrifuge par l'intermédiaire de l'ouverture d'admission et une vis sans fin est disposée dans l'enveloppe de boîtier et fixée sur l'arbre qui traverse la roue et s'engrène dans l'enveloppe de boîtier. Une conduite de refoulement raccord directement ou indirectement une zone côté refoulement de la pompe centrifuge à la chambre intérieure. L'invention vise à perfectionner l'ensemble de pompes à amorçage automatique de ce type en améliorant les conditions se rapportant à la mécanique des fluides, pour l'écoulement du liquide dans et hors de la conduite d'écoulement, en créant une disposition compacte dans l'ensemble et en préfabriquant la conduite de refoulement et ses points de raccordement. Pour ce faire, la conduite de refoulement (9) du côté de la pompe centrifuge est raccordée, à l'intérieur du boîtier (2.1/2.2), à une chambre intérieure (3; 3*, 3**, 3a) côté aspiration disposée après la roue (4) dans le sens d'écoulement, par l'intermédiaire d'un premier point de raccordement (9a).
