Die Erfindung bezieht sich auf eine rotierende Llektro- ■jüiüL)e iiiit eineiii durch einen Asynchronmotor mit ebenen Luftspalt angetriebenen Laufrad, deren rotierende Teile von einer einzigen Lagerschale aus einem Material getragen v/erden, das durch die umlaufende Flüssigkeit schmierbar ist.The invention relates to a rotating Llektro- ■ jüiü L ) e iiiit einiii driven by an asynchronous motor with a flat air gap, the rotating parts of which are carried by a single bearing shell made of a material that can be lubricated by the circulating liquid.

Bei solchen Pumpen mit schmalem Luftspalt und mit einer Anordnung der rotierenden Teile, die vollkommen innerhalb des geförderten Mediums rotieren, ergibt sich das Problem, im geförderten Medium mitgeführte Fremdkörper vom Luftspalt und den Lagern fernzuhalten, so dass sie dort nicht zu Beschädigungen führen können.In such pumps with a narrow air gap and with a Arrangement of the rotating parts, which rotate completely within the conveyed medium, the problem arises in the conveyed Medium entrained foreign bodies from the air gap and the Store away from storage so that they cannot cause damage there.

Es ist bekannt (USÄ-PS 2 066 505), die grössere Dichte der festen Bestandteile zum Fernhalten der festen BeimengungenIt is known (USÄ-PS 2 066 505), the higher density of the solid constituents to keep out the solid admixtures

; Weitere Einzelheiten, Vorteile und Merkmale der Erfindung : ergeben sich aus der folgenden Beschreibung. Auf der Zeichnung . ist die Erfindung beispielsweise dargestellt, und zwar zeigt die Figur einen Axialschnitt durch den flüsaigkeitsgefüllten Raum, in dem die rotierenden Teile einer erfindungsgemässen Pumpe umlaufen.; Further details, advantages and features of the invention : result from the following description. On the drawing . the invention is illustrated by way of example, namely the figure shows an axial section through the liquid-filled space in which the rotating parts of a pump according to the invention revolve.

Eine rotierende Elektropumpe mit ebenem Luftspalt weist einen Motor- und einen Pumpenteil auf. Zum Motorteil gehört ein Läufer 5, der im mit dem zu fördernden Medium gefüllten Raum umläuft und einen stirnseitigen Spalt gegen einen hinter einer Platte vom zu fördernden Medium getrennten Ständer beabstandet ist. Die rotierenden Teile sitzen auf einer Lagerschale aus Graphit, die auf einer hohlen Achse 9 in Umdrehungsrichtung gleitend ange- i ordnet ist. Mit dem Läufer 5 ist ein Laufrad 13 der Pumpe angeord-j net, das das zu fördernde Medium im radial inneren Bereich ansaugt! und im radial äusseren Berich unter Druck abgibt, wo es durch eine Ablaufleitung abfliesst. Der Raum mit dem Läufer 5 und dem Laufrad 13 ist von einem Gehäuse 14 umgeben. _^_A rotating electric pump with a flat air gap has a motor and a pump part. The engine part includes a Runner 5, which rotates in the space filled with the medium to be conveyed and an end gap is spaced from a stand separated from the medium to be conveyed behind a plate. The rotating parts sit on a bearing shell made of graphite, which is slidably attached to a hollow shaft 9 in the direction of rotation is arranged. An impeller 13 of the pump is arranged with the rotor 5, which sucks in the medium to be conveyed in the radially inner area! and releases under pressure in the radially outer area, where it passes through a Drainage drains off. The room with the runner 5 and the impeller 13 is surrounded by a housing 14. _ ^ _
