04 15286?7~04 15 286? 7 ~ PatentansprHohe Patent claim high Kreiselpumpe mit einem einfachen schneckenförmigen Laufrad, das mit Einrichtungen zur Schmierung des Lager3 der Antriebswelle und zur Wärmeabführung versehen ist, dadurch gekennzeichnet, dass daa laufrad (16) auf seiner der Antriebsseite zugewandten Rückseite eine rückwärtige Schale (38) aufweist, die einen Durchgang bildet, durch den ein Teil der Pumpflüssigkeit von einem Hohlraum (A) unterhalb des Laufrades (16) entlang dem Lager bzw· der Stopfbuchse (22) geleitet wird und um diese zirkuliert.Centrifugal pump with a simple helical impeller that is provided with devices for lubricating the bearing3 of the drive shaft and for heat dissipation, characterized in that daa impeller (16) on its rear side facing the drive side a rear shell (38) which forms a passage through which a portion of the pumping liquid from a cavity (A) is passed below the impeller (16) along the bearing or the stuffing box (22) and circulates around them. 2. Kreiselpumpe nach Anspruch 1, dadurch gekennzeichnet, dass der Durchgang von der Lagerzone des Laufrades (16) in die Druckkammer führt. 2. Centrifugal pump according to claim 1, characterized in that the Passage leads from the bearing zone of the impeller (16) into the pressure chamber. 3* Kreiselpumpe nach Anspruch 1 und 2, dadurch, gekennzeichnet, dass die rückwärtige Schale (38) in Verbindung mit an der Rückseite des Laufrades (16) befindlichen Vertiefungen einen ersten Durchgang (39) ergibt, durch den die Flüssigkeit in dem Hohlraum (A) kreisend angetrieben wird.3 * centrifugal pump according to claim 1 and 2, characterized in that the rear shell (38) has a first passage in connection with recesses located on the rear side of the impeller (16) (39) results, through which the liquid in the cavity (A) is driven in a circular motion. 4. Kreiselpumpe nach Anspruch 1 bis 3, dadurch gekennzeichnet, dass das untere Ende der rückwärtigen Schale (38) die Stopfbuchse (22) in einem bestimmten Abstand umgibt und somit einen zweiten Durchgang (39a) bildet, der mit dem ersten Durchgang (39) verbunden ist.4. Centrifugal pump according to claim 1 to 3, characterized in that the lower end of the rear shell (38) surrounds the gland (22) at a certain distance and thus a second passage (39a) which is connected to the first passage (39). 5. Kreiselpumpe nach Anspruch 1 bis 4, dadurch gekennzeichnet, dass durch geeignete Ausbildung der rückwärtigen Schals (38) die Strömungsgeschwindigkeit in den Durchgängen (39, 39a) ausreicht, um an der Lagerstelle sich ansammelnde Gase mitzureissen.5. Centrifugal pump according to claim 1 to 4, characterized in that by suitably designing the rear scarves (38), the flow rate in the passages (39, 39a) is sufficient to entrain any gases that have accumulated at the storage point. 909842/0684909842/0684 ISE/Reg. 34-04ISE / Reg. 34-04 -11--11- 6. Kreiselpumpe nach Anspruch 1 "bis 5, dadurch gekennzeichnet, dass das laufrad (16) an seiner'Frontseite erhabene Schaufeln (36a) und an seiner Rückseite den Schaufeln entsprechende Vertiefungen bzw. Kanäle aufweist·6. centrifugal pump according to claim 1 "to 5, characterized in that that the impeller (16) has raised blades on its front side (36a) and on its rear side the indentations corresponding to the blades or has channels
