Abstract

Die Erfindung betrifft eine Kreiselpumpe 1, die von einem Elektromotor 2 angetrieben ist, der von einer an der der Pumpenkammer 3 abgewandten Stirnseite des Elektromotors 2 angeordneten Elektronikeinheit 4 gesteuert ist, wobei der Elektromotor 2 mindestens einen Förderkanal 19a, 19b aufweist, durch den die geförderte Flüssigkeit zur Kühlung der Elektronikeinheit 4 von der Pumpenkammer 3 bis zu der Elektronikeinheit 4 geführt ist, wobei der Elektromotor 2 mindestens zwei Förderkanäle 19a, 35a und 19b, 35b aufweist, die von unterschiedlichen Druckbereichen der Kreiselpumpe 1 als Hochdruckförderkanal 19a, 35a bzw. als Niederdruckförderkanal 19b, 35b zur Elektronikeinheit 4 geführt sind, und daß mindestens ein Kühlkanal 30 durch die Elektronikeinheit 4 hindurch geführt ist, der an die beiden Förderkanäle 19a, 35a und 19b, 35b derart angeschlossen ist, daß die zur Elektronikeinheit 4 geführte Flüssigkeit die Elektronikeinheit 4 durchströmt.

Figure 00000001
The invention relates to a centrifugal pump 1 which is driven by an electric motor 2, which is controlled by an electronic unit 4 arranged on the front side of the electric motor 2 facing away from the pump chamber 3, the electric motor 2 having at least one delivery channel 19a, 19b through which the pumped Liquid for cooling the electronics unit 4 is guided from the pump chamber 3 to the electronics unit 4, the electric motor 2 having at least two delivery channels 19a, 35a and 19b, 35b, which differ from different pressure ranges of the centrifugal pump 1 as a high-pressure delivery channel 19a, 35a or as a low-pressure delivery channel 19b, 35b are led to the electronics unit 4, and that at least one cooling channel 30 is passed through the electronics unit 4, which is connected to the two delivery channels 19a, 35a and 19b, 35b in such a way that the liquid fed to the electronics unit 4 flows through the electronics unit 4 ,
