Abstract

Die Erfindung bezweckt die Schaffung einer Befestigungs­ einrichtung für aus sprödem Material bestehende Kreisel­ pumpenlaufräder, die zwei Bedingungen erfüllt: The invention aims to provide a fastening device for gyroscope made of brittle material pump impellers that meet two conditions:

Erstens dürfen durch die Befestigungseinrichtung wegen der bestehenden Bruchgefahr keine Zugkräfte in das Kreisel­ pumpenlaufrad eingeleitet werden; First, because of the existing risk of breakage no tensile forces in the gyro pump impeller are initiated;

zweitens darf die durch das Laufrad und durch die Kreiselpumpe fließende Strömung durch die Befestigungseinrichtung nicht gestört werden. secondly, through the impeller and through the centrifugal pump flowing flow through the fastener is not be disturbed.

Demgemäß ist das Kreiselpumpenlaufrad (1) auf seiner Druckseite in einer Scheibe (2) aus duktilem Material gefaßt, wobei die Verbindung zwischen dem Kreiselpumpenlaufrad (1) und der Scheibe (2) im Bereich des Außendurchmessers erfolgt. Accordingly, the centrifugal pump impeller (1) is in on its pressure side a disc (2) made of ductile material, the connection between the centrifugal pump impeller (1) and the disc (2) in the area of Outside diameter takes place.
