Description
Die Erfindung bezieht sich auf eine einstufige Kreiselpumpe, bei der die Pumpenwelle mit Laufrad und die Pumpenwellenlager nebst einer sie verbindenden und aufnehmenden Büchse eine zusammenhängende; Einheit, bilden; die im Pumpengehäuse verschieblich und feststellbar angeerdnet ist, und die erfindungsgemäß dadurch gekennzeichnet ist, daß der die Bohrung zur Aufnahme der Büchse umgebende Gehäuseteil zylindermantelförmig ausgebildet und mit Längsschlitzen vorsehen is-t und daß auf diesem Teil eine KlemmscheQle angeordnet ist.The invention relates to a single-stage centrifugal pump in which the pump shaft with impeller and the pump shaft bearings together with one connecting them and female bushing a contiguous; Unity, form; those in the pump housing is displaceable and lockable, and is characterized according to the invention is that the housing part surrounding the bore for receiving the sleeve is cylindrical is designed and provided with longitudinal slots and that a clamp on this part is arranged.
Dadurch ist die Montage einer derartigen Kreiselpumpe wesentlich vereinfacht worden, denn die erwähnte zusammenhängende Einheit kann als Bauteil für sich hergestellt, werden, der bei der Montage der Pumpe einfach in die Bohrung des Pumpengehäuses eingeschoben und durch das Anziehen des gewissermaßen als Klemmzange ausgebildeten Gehäuseteils festgehalten wird. Ferner kann durch die Verschiebung der Einheit bzw. ihrer Büchse die Größe des Dichtspalts, das heißt der Abstand zwischen dem Laufrad und dem saugseitigen Pumpengehäuseteiil, in einfacher Weise eingestellt werden.As a result, the assembly of such a centrifugal pump is significantly simplified because the mentioned coherent unit can be manufactured as a component in itself, simply insert it into the bore of the pump housing when assembling the pump inserted and formed by tightening the clamp, so to speak Housing part is held. Furthermore, by moving the unit or your bushing the size of the sealing gap, i.e. the distance between the impeller and the suction-side pump housing part, can be adjusted in a simple manner.
Die Erfindung bietet die Möglichkeit, den kleinsten Abstand oder Dichtspalt dadurch zu erhalten, daß man bei der Montage das konisches Laufrad an der Flächei des Saugdeckels anstehen läßt, worauf sich beiim Betrieb oder beim Probelauf das Laufrad in den Saugdeckel einschleift.The invention offers the possibility of the smallest distance or sealing gap to be obtained by the fact that the conical impeller on the Flächei during assembly the suction cover can stand, which can be seen during operation or during a test run Grinds the impeller into the suction cover.
In der Zeichnung sind von einer Kreiselpumpe die hier interessierenden Teile in einem mittleren Längsschnitt in einer beispielsweisen Ausführungsform dargestellt.The drawing shows the centrifugal pumps that are of interest here Parts shown in a central longitudinal section in an exemplary embodiment.
In das Pumpengehäuse i ist der Saugdeckel z eingesetzt, dessen dem Laufrad 3 bzw. sdinen Flügeln 3' gegenüberliegende Fläche 2' konisch gestaltet ist. In axialer Übereinstimmung mit der Wassereintrittsöffnung 4 des Saugdeckels 2 ist das Pumpengehäuse mit einer Bohrung 5 versehen, dessen antriebsseitig gelegener Teil i' beim vorliegenden Beispiel zylindrisch gestaltet und mit einigen Längsschlitzen 6 versehen ist. Dieser zylindrische Teil i', den man als Klemmzange bezeichnen könnte, ist von einer Klemmschelle 7 umgeben, die durch eine Schraube 8 zusammenziehbar ist. Der in deir Gehäusebohrung 5 befindliche Lagersatz, der ein zusammenhängendes Ganzes bildet, besteht aus der Pumpenwelle 9, dem Laufrad 3, den verschiedenen Kugellagern io, il und einer Büch.sv 12, in der die gesamtem. Wellenlager io, il aufgenommen sind. Geeignete Dichtungsmittel, beispielsweise die in der Zeichnung dargestellten Dichtringe 13, sind auf der Welle 9. zwischen dem Laufrad und der Bü chse 12 angeordnet. Ferner trägt die Welle 9 das Antriebsritzel 14, in welches ein in der Zeichnung nicht dargestelltes elektromotorisch angetriebenes Zahnrad eingreift. Der ganze Lagersatz #.st als Ganzes in die Gehäusebohrung 5 einsietzbar. Seine Festlegung erfolgt durch Anziehen der Klemmschelle 7, nachdem der sogenannte Dichtspalt a zwischen dem Saugdeckel 2 und dein konisch gestalteten Laufradflüge@n 3' eingestellt worden ist. Vorzugsweise sind diese Laufradflügel 3' in den Saugdeckel 2 eingeschliffen, so daß der Dichtspalt ein Minimum beträgt.In the pump housing i, the suction cover z is used, whose dem Impeller 3 or sdinen blades 3 'opposite surface 2' is designed conically. In axial correspondence with the water inlet opening 4 of the suction cover 2 is the pump housing is provided with a bore 5, the one located on the drive side Part i 'in the present example designed cylindrically and with some longitudinal slots 6 is provided. This cylindrical part i ', which could be called a clamp, is surrounded by a clamp 7 which can be pulled together by a screw 8 is. The bearing set located in deir housing bore 5, which is a coherent Forms a whole, consists of the pump shaft 9, the impeller 3, the various ball bearings io, il and a Büch.sv 12, in which the entire. Shaft bearings io, il added are. Suitable sealing means, for example those shown in the drawing Sealing rings 13 are arranged on the shaft 9 between the impeller and the bush 12. Furthermore, the shaft 9 carries the drive pinion 14, in which a in the drawing Gearwheel, not shown, driven by an electric motor engages. The whole Bearing set #. Can be inserted as a whole in the housing bore 5. Its definition takes place by tightening the clamp 7 after the so-called sealing gap a between the suction cover 2 and your conical impeller flights @ n 3 'have been set is. These impeller blades 3 'are preferably ground into the suction cover 2, so that the sealing gap is a minimum.
