Abstract
Description
Die Erfindung betrifft ein Spaltrohr einer Kreiselpumpe mit einem an beiden Enden offenem Rohr und einem pumpenseitig angeformten flanschförmigen Lagerschild, das den Motorstatorraum von der Pumpenkammer trennt.The The invention relates to a can of a centrifugal pump with a both ends of the open tube and a flange-shaped end shield formed on the pump side, which separates the motor stator space from the pump chamber.
Bei einem Spaltrohr für eine Kreiselmotorpumpe ist es bekannt, die für die Motorenwelle erforderlichen Lagerträger als zusätzliche Teile im Spaltrohr zu befestigen. Dies erfordert einen zusätzlichen Montageaufwand mit einer hohen Herstellgenauigkeit und zusätzliche Dichtungen.at a can for a rotary engine pump, it is known that required for the motor shaft bearing bracket as additional To secure parts in the can. This requires an additional installation effort with a high manufacturing accuracy and additional seals.
Aufgabe der Erfindung ist es ein Spaltrohr der Eingangs genannten Art so zu verbessern, dass bei einfacher Konstruktion wenig Einzelteile und ein geringer Montageaufwand erforderlich sind und hierbei eine hohe Herstellgenauigkeit erreicht wird.task of the invention, it is a can of the aforementioned type so to improve that with simple construction few items and a low installation costs are required and this one high manufacturing accuracy is achieved.
Diese
Aufgabe wird erfindungsgemäß dadurch
gelöst,
dass pumpenseitig in Höhe
des Lagerschildes koaxial am Spaltrohr ein buchsenförmiger Lagersitz
(
Die Einstückigkeit von Spaltrohr und dem pumpenseitigen Lagersitz verringert die Anzahl der Einzelteile und erhöht die Herstellgenauigkeit, da die Fluchtung zwischen Flanschzentrierung und Lagerstelle erheblich verbessert ist. Ferner werden Dichtungen eingespart und der Montageaufwand verringert. Vorzugsweise besteht hierbei das Spaltrohr aus Kunststoff.The one-piece of canned and the pump-side bearing seat reduces the number of items and increases the manufacturing accuracy, since the alignment between Flanschzentrierung and bearing is significantly improved. Furthermore, seals saved and reduced assembly costs. Preferably exists here the canned plastic.
Die Stabilität des Spaltrohres wird erhöht, wenn außen auf dem Spaltrohr ein Versteifungsrohr insbesondere aus Kohlefaserverstärktem Kunststoff aufsitzt. Hierdurch wird eine Modularität erreicht, d.h. bei niedrig belasteten Systemen kann das Versteifungsrohr fehlen und bei hoher Belastung aufgeschoben werden.The stability of the can is increased when Outside on the canned a stiffening tube in particular made of carbon fiber reinforced plastic sits. This will be a modularity reached, i. For low loaded systems, the stiffening tube missing and postponed at high load.
Besonders vorteilhaft ist es, wenn außen am Lagerschild pumpenseitig eine Buchse koaxial angeformt ist, die zur Pumpe hin vorsteht. Hierbei ist der Innendurchmesser der Buche größer als der Außendurchmesser des Lagersitzes. Besonderes vorteilhaft ist eine solche Konstruktion verwendbar, wenn zwischen der Buchse und dem Lagersitz ein Ringraum besteht, in dem mindestens ein insbesondere ringförmiges Filterelement einsitzt.Especially it is advantageous if outside on the bearing plate pump side, a socket coaxially formed, the projecting towards the pump. Here is the inner diameter of the beech greater than the outside diameter of the bearing seat. Particularly advantageous is such a construction usable, if between the bush and the bearing seat an annular space consists, in the at least one particular annular filter element seated.
Eine besonders gute Strömungsführung in der Pumpenkammer und damit geringe Verwirbelungen werden erreicht, wenn außen an der Buchse ein ringförmiges Abdeckelement insbesondere aus Kunststoff koaxial befestigt ist, das das Lagerschild außen in der Pumpenkammer zumindest teilweise überdeckt.A particularly good flow guidance in the Pump chamber and thus low turbulence are achieved when Outside at the socket an annular Covering element is attached coaxially, in particular made of plastic, that the bearing plate outside at least partially covered in the pump chamber.
Ausführungsbeispiele der Erfindung sind in den Zeichnungen in axialen Schnitten dargestellt und werden im folgenden näher beschrieben, wobei das Pumpengehäuse weggelassen wurde. Es zeigenembodiments The invention are illustrated in the drawings in axial sections and will be closer in the following described, wherein the pump housing was omitted. Show it
