Description

Bei Schlauchradpumpen könnten an sich zwar zur Wellenspaltabdichtung, wie 1;°i Kreiselpumpen üblich, offene Rückschaufeln, geschlossene Rückförderräder u. dgl. angewendet werden. Diese ergeben aber eine strömungstechnisch ungünstige Form für das Laufrad.In the case of peristaltic pumps, it is true that the shaft gap sealing As usual in 1; ° i centrifugal pumps, open back blades, closed return wheels and the like can be applied. However, these result in an unfavorable flow technology Shape for the impeller.

Nach der Erfindung werden daher für die NVellenspaltabdichtung, von der Rückseite des Schlauchrades zur äußersten Spitze der Schlauchradkanäle führend, der Schlauchradform angepaßte Kanäle vorgesehen.According to the invention, therefore, for the N-cell gap seal, from leading the back of the hose wheel to the extreme tip of the hose wheel channels, the hose wheel shape adapted channels are provided.

In der Zeichnung ist eine Schlauchradpumpe mit den Merkmalen gemäß der Erfindung dargestellt.In the drawing is a hose pump with the features according to of the invention shown.

In der Wandung des Schlauchrades sind zur äußersten Spitze führende Kanäle a. abgeordnet, durch welche die durch den rückseitigen Ringspalt b des Schlauchrades durchtretend--. Spaltflüssigkeit in den Druckraum der Pumpe gefördert wird.In the wall of the hose wheel are leading to the extreme tip Channels a. delegated through which the through the rear annular gap b of the hose wheel stepping through--. Cleavage fluid is conveyed into the pressure chamber of the pump.
