Abstract
Die Erfindung bezweckt die Schaffung einer Befestigungs
einrichtung für aus sprödem Material bestehende Kreisel
pumpenlaufräder, die zwei Bedingungen erfüllt:
Erstens dürfen durch die Befestigungseinrichtung wegen der
bestehenden Bruchgefahr keine Zugkräfte in das Kreisel
pumpenlaufrad eingeleitet werden;
zweitens darf die durch das Laufrad und durch die Kreiselpumpe
fließende Strömung durch die Befestigungseinrichtung nicht
gestört werden.
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.
