Description

Abdichtung der Treibwelle von Drehkolbenpumpen für Flüssigkeiten oder Gase. Gegenstand der Erfindung ist eine Abdichtung der Treibwelle von Drehkolbenpumpen für Flüssigkeiten oder Gase.Sealing of the drive shaft of rotary lobe pumps for liquids or Gases. The invention relates to a seal for the drive shaft of rotary lobe pumps for liquids or gases.

Die Abb. i und z zeigen eine Ausführungsform der Erfindung.Figs. I and z show an embodiment of the invention.

In der Stirnwand des Gehäuses a ist die Treibwelle gelagert. Der Kurbelzapfen e trägt die Kolbentrommel d, die durch die Kurbel an dem Umfang der Gehäusewand. entlang bewegt wird. e ist das Widerlager, welches das Gehäuse a zusammen mit Trommel d in zwei Räume teilt, deren einer bei der Bewegung zunimmt (Saugraum), während der andere sich verringert (Druckraum).The drive shaft is mounted in the end wall of the housing a. The crank pin e carries the piston drum d, which is attached to the circumference of the housing wall by the crank. is moved along. e is the abutment, which the housing a together with the drum d divides into two spaces, one of which increases with movement (suction space), while the other is reduced (pressure space).

Das Fördermittel (Gas, Wasser, Luft o. dgl.) tritt bei fein. und bei g aus. Der schädliche Raum .ist also fast gleich Null. Das Widerlager e kann entweder im Gehäuse oder an der Kolbentrommel angelenkt und dementsprechend entweder in der Kolbentrommel. (Abb. i) oder im Gehäuse geradegeführt sein. Die Seiten können durch. federnde Dichtungsleisten abgedichtet werden. Der Kurbelarm i ist als kreisförmige Scheibe ausgeführt, die durch den Förderdruck gegen einen Dichtungsring gedrückt wird, so daß sich eine Stopfbüchse erübrigt.The funding (gas, water, air or the like) occurs at fine. and at g off. The harmful space. Is therefore almost nil. The abutment e can either hinged in the housing or on the piston drum and accordingly either in the Piston drum. (Fig. I) or straight out in the housing. The pages can go through. resilient sealing strips are sealed. The crank arm i is as circular Washer executed, which is pressed by the delivery pressure against a sealing ring so that a stuffing box is unnecessary.
