Description
Die Erfindung betrifft eine Kreiselpumpe gemäß dem Oberbegriff des Anspruchs 1, die aus
Kreiselpumpen mit einer oder mehr Stufen sind im Stand der Technik bekannt und sind aufgrund ihrer einfachen und robusten Bauart weit verbreitet.Centrifugal pumps with one or more stages are known in the art and are widely used because of their simple and robust design.
Bei derartigen Pumpen gibt es unterschiedliche Bauformen, so sind bei Inline-Pumpen Druck- und Saugstutzen achsgleich im Fuß der Pumpe angeordnet. Es sind jedoch auch Pumpen bekannt, bei denen der Saugstutzen im Pumpenfuß und der Druckstutzen in einem gesonderten Bauteil nahe dem oberen Ende der Pumpe angeordnet ist. So können zwar die Gehäuseteile in der Regel für Pumpen unterschiedlicher Druckstufen eingesetzt werden, die Anordnung von Saugstutzen und Druckstutzen zueinander bedingt jedoch stets eine Änderung der entsprechenden Bauteile, was die Teilevielfalt bei der Herstellung, Lagerung und Ersatzteilbevorratung erhöht.In such pumps, there are different types, so inline pumps pressure and suction are arranged coaxially in the foot of the pump. However, pumps are also known in which the suction nozzle in the pump base and the discharge nozzle are arranged in a separate component near the upper end of the pump. Thus, although the housing parts are usually used for pumps of different pressure levels, the arrangement of suction nozzle and discharge nozzle to each other, however, always requires a change of the corresponding components, which increases the variety of parts in the production, storage and spare parts inventory.
Vor diesem Hintergrund liegt der Erfindung die Aufgabe zugrunde, eine gattungsgemäße Kreiselpumpe, insbesondere eine mehrstufige Kreiselpumpe so auszubilden, dass unterschiedliche Anschlussvarianten mit möglichst viel Gleichteilen aufgebaut werden können.Against this background, the invention has the object, a generic centrifugal pump, in particular a multi-stage centrifugal pump in such a way that different connection variants can be constructed with as many common parts.
Diese Aufgabe wird gemäß der Erfindung durch eine Kreiselpumpe mit den in Anspruch 1 angegebenen Merkmalen gelöst. Vorteilhafte Weiterbildungen der Erfindung sind in den Unteransprüchen definiert und der nachfolgenden Beschreibung angegeben.This object is achieved according to the invention by a centrifugal pump having the features specified in claim 1. Advantageous developments The invention are defined in the subclaims and the following description.
Die erfindungsgemäße Kreiselpumpe weist mindestens eine Pumpenstufe auf und hat ein mehrteiliges Gehäuse, mit einem ersten Gehäuseteil, welches einen Sauganschluss aufweist, mit einem zweiten Gehäuseteil, welches einen Druckanschluss aufweist und mit mindestens einem Zwischengehäuseteil, welches einen zu der Druckseite der mindestens einen Pumpenstufe führenden Kanal zumindest abschnittsweise begrenzt, und mit einem dritten Gehäuseteil, wobei das zweite Gehäuseteil und das mindestens eine Zwischengehäuseteil zwischen dem ersten und dem dritten Gehäuseteil angeordnet sind, wobei das mindestens eine Zwischengehäuseteil und das zweite Gehäuseteil zur Anordnung in mindestens zwei unterschiedlichen Stellungen bezogen auf das erste und dritte Gehäuseteil ausgebildet sind. Bei der erfindungsgemäßen Konfiguration wird der Freiheitsgrad für die Positionierung des zweiten Gehäuseteils, das den Druckanschluss aufweist, erhöht. Hierdurch können insbesondere der Druckanschluss in unterschiedlichen Stellungen angeordnet werden, ohne die Bauteile konstruktiv zu ändern.The centrifugal pump according to the invention has at least one pump stage and has a multi-part housing, with a first housing part, which has a suction port, with a second housing part, which has a pressure port and at least one intermediate housing part, which leading to the pressure side of the at least one pump stage channel at least partially limited, and with a third housing part, wherein the second housing part and the at least one intermediate housing part between the first and the third housing part are arranged, wherein the at least one intermediate housing part and the second housing part for arrangement in at least two different positions with respect to the first and third housing part are formed. In the configuration according to the invention, the degree of freedom for the positioning of the second housing part, which has the pressure connection, is increased. In this way, in particular, the pressure port can be arranged in different positions, without changing the components constructively.
Grundgedanke der vorliegenden Erfindung ist es, die vorhandenen Gehäuseteile, insbesondere das mindestens eine Zwischengehäuseteil und das zweite Gehäuseteil so auszubilden, dass diese zusammen oder auch einzeln in unterschiedlichen Stellungen bezogen auf das erste und dritte Gehäuseteil angeordnet werden können, sodass mit denselben Bauteilen der Druckanschluss in seiner Anordnung verändert werden kann ohne die Bauteile verändern zu müssen.The basic idea of the present invention is to design the existing housing parts, in particular the at least one intermediate housing part and the second housing part, so that they can be arranged together or individually in different positions with respect to the first and third housing part, so that the pressure connection in FIG Its arrangement can be changed without having to change the components.

Teure Umlenkstücke und Leitungen können eingespart werden, da das den Druckanschluss aufweisende zweite Gehäuseteil und das Zwischengehäuseteil in beliebiger Reihenfolge angeordnet werden können, was insbesondere heißt, dass mittels dieser Konfiguration der Druckanschluss im Hinblick auf die Kreiselpumpe oben oder weiter unten und unabhängig von den Stufen der Kreiselpumpe angeordnet werden kann.According to a preferred embodiment, the at least one intermediate housing part and the second housing part are designed for arrangement in at least two different longitudinal positions relative to the rotary axis of the pump. In this embodiment of the centrifugal pump a variable positioning of the pressure port is made possible, in particular in the axial and optionally also in the radial direction of the centrifugal pump. Due to the increased degrees of freedom in the positioning of the pressure port to the suction port, the centrifugal pump is more flexible, and it can be a better adaptation to different installation situations realized. Expensive deflectors and lines can be saved because the pressure connection having the second housing part and the intermediate housing part can be arranged in any order, which means in particular means that by means of this configuration, the pressure connection with respect to the centrifugal pump above or below and regardless of the stages Centrifugal pump can be arranged.
Gemäß einer bevorzugten Ausführungsform hat das mindestens eine Zwischengehäuseteil eine im Wesentlichen hohlzylindrische Form und begrenzt den zwischen der Druckseite der mindestens einen Pumpenstufe und dem Druckanschluss gebildeten Kanal, der in diesem Bereich als Ringkanal ausgebildet ist, außenseitig.According to a preferred embodiment, the at least one intermediate housing part has a substantially hollow cylindrical shape and limits the channel formed between the pressure side of the at least one pump stage and the pressure port, which is formed in this area as an annular channel, on the outside.

Gemäß einer weiteren bevorzugten Ausführungsform sind das mindestens eine Zwischengehäuseteil und das den Druckanschluss aufweisende zweite Gehäuseteil an zwei Seiten, die jeweils an ein weiteres Gehäuseteil anschließen, anschlussgleich ausgebildet. Dies ermöglicht eine beliebige Anordnung der einzelnen Komponenten zueinander.According to a further preferred embodiment, the at least one intermediate housing part and the second housing part having the pressure connection are formed on two sides, which in each case connect to a further housing part, with the same connection. This allows any arrangement of the individual components to each other.
Besonders bevorzugt ist es, wenn das mindestens eine Zwischengehäuseteil und das den Druckanschluss aufweisende zweite Gehäuseteil modular aufgebaut sind.It is particularly preferred if the at least one intermediate housing part and the second housing part having the pressure connection are of modular design.
Vorzugsweise sind das mindestens eine Zwischengehäuseteil und das den Druckanschluss aufweisende zweite Gehäuseteil zwischen dem ersten und dem dritten Gehäuseteil eingespannt.Preferably, the at least one intermediate housing part and the second housing part having the pressure connection are clamped between the first and the third housing part.
