Abstract
Das Spiralgehäuse weist im mittleren Bereich M der Strömungsspirale einen Strömungsquerschnitt auf, dessen Verhältnis der Länge X zur Breite Y im Bereich von 1,5 bis 2 liegt. Das Verhältnis der ersten Teilhöhe Y1 zur zweiten Teilhöhe Y2, die durch den Schnittpunkt P der Länge X und der Breite Y an einer Seite begrenzt sind, liegt im Bereich von 0,25 bis 1. Die am nächsten an dem Eintritt E des Strömungsmediums liegende und parallel zur Längsachse des Eintritts E verlaufende Begrenzung j des Strömungsquerschnitts steht mit der dem Laufrad der Kreiselpumpe am nächsten liegenden weiteren Begrenzung h des Strömungsquerschnitts im rechten Winkel alpha zueinander. Gegenstand ist ferner die Verwendung des Spiralgehäuses als Gehäuse für eine Kühlwasser-Kreiselpumpe in einem Kraftfahrzeug.The spiral housing has a flow cross-section in the central region M of the flow spiral whose ratio of the length X to the width Y is in the range of 1.5 to 2. The ratio of the first partial height Y1 to the second partial height Y2, which are limited by the intersection point P of the length X and the width Y on one side, is in the range of 0.25 to 1. The lying closest to the inlet E of the flow medium and Parallel to the longitudinal axis of the inlet E running boundary j of the flow cross-section is with the impeller of the centrifugal pump next lying further boundary h of the flow cross-section at right angles alpha to each other. The subject is also the use of the spiral housing as a housing for a cooling water centrifugal pump in a motor vehicle.
