POMPE CENTRIFUGE A ROUE A AUBES OUVERTE

摘要

Arranged in the pump casing (1) there is an impeller (2) which rotates about a vertical axis. Arranged on the pump casing (1) wall facing the pump inlet (4) there is a rib (3) which runs parallel to a tangential plane of the impeller (2). It is joined to the casing (1) monolithically or in some other manner and is situated directly next to the impeller (2). The simultaneous delivery of solid flow components is ensured by this measure in the case of the centrifugal pump which has a vane inlet arranged in the hub region. <IMAGE>
