Description

Die Erfindung betrifft ein Gehäuse gemäß dem Oberbegriff des Hauptanspruches.The invention relates to a housing according to the preamble of the main claim.

Aus der DE-PS 32 10 526 ist ein Inline-Gehäuse für einstufige Pumpen bekannt, welches aus zwei Formhälften besteht, deren Teilungsebene in der Ebene der Pumpenwelle liegt. Die gezeigte Verwendung eines Spiralgehäuses bedingt zwei unterschiedliche Gehäuseformhälften, weshalb für die unterschiedlichen Größen einer Baureihe immer zwei verschiedene Werkzeuge zur Herstellung der Gehäusehälften erforderlich sind. Eine in das Gehäuse eingelegte Zwischenwand wird in einer quer zur Teilungsebene verlaufenden Ebene mit den beiden Gehäusehälften verbunden. Dies erfordert einen zusätzlichen Aufwand, da diese Teile nachträglich in ein bereits hergestelltes Gehäuse eingelegt und dort zuverlässig verbunden werden müssen. Bei der Konstruktion gemäß der US-PS 30 59 582 ist ein nach Inline-­Bauart ausgeführtes Topfgehäuse mit angeformten Stutzen versehen und ebenfalls mit einer nachträglich eingelegten Zwischenwand ausgerüstet.From DE-PS 32 10 526 an inline housing for single-stage pumps is known, which consists of two mold halves, the parting plane of which lies in the plane of the pump shaft. The use of a spiral housing shown requires two different housing halves, which is why two different tools are always required to produce the housing halves for the different sizes of a series. An intermediate wall inserted into the housing is connected to the two housing halves in a plane running transversely to the division plane. This requires additional effort, since these parts have to be subsequently inserted into a housing that has already been produced and reliably connected there. In the construction according to US Pat. No. 3,059,582, an in-line design of the pot housing is provided with molded nozzles and is also equipped with a partition wall which is inserted subsequently.

Für eine mehrstufige Kreiselpumpe in Inline-Bauart ist aus der DE-PS 27 07 776 eine Lösung bekannt, derzufolge ein als Spritzguß- oder Gußkonstruktion ausgebildetes Zwischengehäuse in Inline-Bauart mit integrierter Zwischenwand versehen ist.For a multi-stage centrifugal pump in inline design, a solution is known from DE-PS 27 07 776, according to which an intermediate housing designed as an injection molding or cast construction in an inline design is provided with an integrated partition.

Dieses Zwischengehäuse weist gleichzeitig einen Anschluß­flansch zur Aufnahme eines Antriebsmotors auf und ist an der dem Motor gegenüberliegenden Seite mit Anlageflächen für mehrere nachgeordnete Stufengehäuse versehen. Innerhalb des Zwischengehäuses erfolgt eine Trennung zwischen Saug- und Druckraum sowie an der Zwischwand die Vorsehung einer Wellendurchführung und einer Wellenabdichtung.This intermediate housing has at the same time a connection flange for receiving a drive motor and is provided on the side opposite the motor with contact surfaces for a plurality of downstream step housings. Within the intermediate housing, there is a separation between the suction and pressure chamber, and a shaft bushing and shaft seal are provided on the intermediate wall.

Der Erfindung liegt die Aufgabe zugrunde, für ein- oder mehrstufige Pumpen ein Gehäuse in Inline-Bauart zu entwickeln, welches bei einfachem Aufbau und wenig aufwendiger Herstellung auf das Gehäuse einwirkende Rohrleitungskräfte zuverlässig aufnehmen und weiterleiten kann. Die Lösung dieser Aufgabe erfolgt gemäß dem kennzeichnenden Teil des Hauptanspruches.The invention has for its object to develop a housing for single or multi-stage pumps in inline design, which can easily absorb and transmit pipeline forces acting on the housing with a simple structure and less expensive manufacture. This object is achieved in accordance with the characterizing part of the main claim.

Infolge dieser Lösung ergibt sich eine äußerst einfache Montage, da die das Gehäuse bildenden drei Einzelteile wenig aufwendig zu positionieren sind und in einer Aufspannung miteinander verbunden werden können. Dies kann durch Kleben, Löten, Schweißen oder dgl. erfolgen und hat den Vorteil, daß die Fügenaht nur in einer Ebene verläuft und unter Verwendung von Automaten der Fügevorgang leicht vollziehbar ist. Zu diesem Zweck kann die Zwischenwand und/oder die an der Zwischenwand liegenden Gehäuseteile mit Hilfe eines angebrachten Flansches über die Gehäusekontur hinausragen und somit gleichzeitig für eine Verschweißung zur Verfügung stehen. Infolge der an der Zwischenwand angebrachten Saug- und Druckstutzenteile ist neben der Möglichkeit einer verlustarmen Strömungsführung der Vorteil gegeben, daß ein direkter Kraftfluß beispielsweise vom Gehäusesaugstutzen über den Saugstutzenteil der Zwischenwand direkt auf die Zwischenwand und von dieser über den Druckstutzenteil der Zwischenwand auf den Druckstutzen des Gehäuses erfolgen kann. Die Zwischenwand übt somit eine außerordentliche Versteifungsfunktion auf das Gehäuse aus und vermeidet infolge der angebrachten Saug- und Druckstutzenteile bei einer Belastung durch Rohrleitungskräfte eine Verformung des Gehäuses.As a result of this solution, assembly is extremely simple, since the three individual parts forming the housing can be positioned with little effort and can be connected to one another in one setting. This can be done by gluing, soldering, welding or the like. It has the advantage that the joining seam runs only in one plane and the joining process can be carried out easily using automatic machines. For this purpose, the intermediate wall and / or the housing parts lying on the intermediate wall can protrude beyond the housing contour with the aid of an attached flange and can thus be available for welding at the same time. As a result of the suction and pressure nozzle parts attached to the intermediate wall, in addition to the possibility of low-loss flow guidance, there is the advantage that a direct power flow, for example from the housing suction nozzle via the suction nozzle part of the intermediate wall, directly to the intermediate wall and from this via the pressure nozzle part of the intermediate wall to the pressure nozzle of the housing can be done. The partition wall thus exercises an extraordinary Stiffening function on the housing and prevents deformation of the housing due to the attached suction and pressure nozzle parts when subjected to pipeline forces.

Eine Ausgestaltung der Erfindung sieht vor, daß die beiden Gehäusehälften spiegelbildlich ausgebildet sind, wobei die den Druckraum bildende Gehäusehälfte in ihrem Bodenbereich eine mittige Öffnung aufweist. Infolge dieser Maßnahme können mit einer Form bzw. einem Werkzeug beide Gehäusehälften erstellt werden. Zwecks Verbindung mit einem dem Gehäuse nachgeordneten Pumpengehäuse oder Stufengehäuse, wie bei mehrstufigen Kreiselpumpen, genügt es, eine der Gehäuse­hälften mit einer einfach auszustanzenden mittigen Öffnung zu versehen, welche eine Verbindung mit einem nachgeschalteten Laufrad oder Stufengehäuse ermöglicht.One embodiment of the invention provides that the two housing halves are mirror images, the housing half forming the pressure chamber having a central opening in its bottom region. As a result of this measure, both housing halves can be created with one mold or one tool. For the purpose of connection to a pump housing or stage housing downstream of the housing, as in multi-stage centrifugal pumps, it is sufficient to provide one of the housing halves with a central opening which can be easily punched out and which enables a connection to a downstream impeller or stage housing.

Nach einer weiteren Ausgestaltung der Erfindung liegen die an der Zwischenwand angebrachten Saug- und Druckstutzenteile an den von den Gehäusehälften gebildeten Saug- und Druckstutzen an und/oder ragen in diese hinein. Je nach der im Einzelfall günstigsten Formgebung sowie den erforderlichen Dichtheits­anforderungen können die Saug- und Druckstutzenteile der Zwischenwand in der jeweils vorteilhaftesten Weise mit den Saug- und Druckstutzen des Gehäuses zusammenwirken.According to a further embodiment of the invention, the suction and pressure nozzle parts attached to the intermediate wall rest against and / or protrude into the suction and pressure nozzles formed by the housing halves. Depending on the shape that is most favorable in the individual case and the required tightness requirements, the suction and pressure connector parts of the intermediate wall can interact with the suction and pressure connectors of the housing in the most advantageous manner in each case.

Eine vorteilhafte Ausgestaltung der Erfindung sieht hierzu vor, daß die an der Zwischenwand angebrachten Saug- und Druckstutzenteile in Richtung der Fügeebene längsgeteilt sind. Infolge des gegenüber der Fügeebene wechselseitigen Verlaufes und der in Richtung der Fügeebene längsgeteilten Saug- und Druckstutzenteile wird neben einer leichten Formbarkeit, beispielsweise im Wege des Tiefziehens, ein äußerst günstiger Kraftfluß innerhalb des Gehäuses erzeugt. Hierbei erfolgt eine direkte Kräfteübertragung zwischen den einander gegenüberliegenden Stutzen.An advantageous embodiment of the invention provides for this that the suction and pressure nozzle parts attached to the intermediate wall are longitudinally divided in the direction of the joining plane. As a result of the reciprocal course relative to the joining plane and the suction and pressure nozzle parts which are longitudinally divided in the direction of the joining plane, an extremely favorable flow of force within the housing is produced in addition to being easy to form, for example by deep drawing. In this case, there is a direct transfer of forces between the opposing nozzles.

Nach einer weiteren Ausgestaltung der Erfindung liegt an der Öffnung der Zwischenwand dichtend ein nachgeschaltetes Pumpen- oder Stufengehäuse an bzw. in bekannter Weise bildet die Öffnung der Zwischenwand für ein Laufrad einen entsprechenden Drosselspalt. Die Verbindung des Gehäuses in Inline-Bauart mit nachgeschalteten Bauteilen erfolgt durch bekannte Mittel.According to a further embodiment of the invention, a downstream pump or stage housing seals against the opening of the intermediate wall or, in a known manner, the opening of the intermediate wall forms a corresponding throttle gap for an impeller. The inline design of the housing is connected to downstream components by known means.

  • Fig. 2 is a plan view
  • Fig. 3 is a side view in section and the
  • 4 and 5 sectional views of suction and pressure ports.

Das in der Fig. 1 gezeigte Gehäuse in Inline-Bauart besteht aus zwei baugleichen Gehäusehälften (1, 2), zu deren Herstellung nur ein Formwerkzeug erforderlich ist. Eine Zwischenwand (3), welche in der Fügeebene (4) der beiden Gehäusehälften (1, 2) angeordnet ist, unterteilt das Gehäuseinnere in einen Saugraum (5) und einen Druckraum (6). An der Zwischenwand (3) angebrachte Saugstutzenteile (7) sowie Druckstutzenteile (8) sind gegenüber der Fügeebene (4) wechselseitig angeordnet. Bei dem hier gezeigten Ausführungs­beispiel befindet sich der angeformte, längsgeteilte und rinnenförmige Saugstutzenteil (7) oberhalb der Fügeebene (4) und erstreckt sich vollständig in den von den beiden Gehäusehälften gebildeten Saugstutzen (9). Der entsprechend ausgebildete Druckstutzenteil (8) liegt in dem Ausführungs­beispiel unterhalb der Fügeebene (4) und innerhalb des Druckstutzens (10). Eine innerhalb der Zwischenwand (3) angebrachte Öffnung (11) ermöglicht ein Überströmen vom Saugraum in den Druckraum, wobei der Öffnung (11) ein Laufrad oder - wie gestrichelt dargestellt - ein Stufengehäuse (12) nachgeordnet sein kann. Zur Anbringung derselben weist die hier obere Gehäusehälfte (1) eine mittige Öffnung (13) auf, welche mit Hilfe eines einfachen Stanzwerkzeuges leicht herstellbar ist.The housing shown in Fig. 1 in inline design consists of two identical housing halves (1, 2), for the manufacture of which only one mold is required. An intermediate wall (3), which is arranged in the joining plane (4) of the two housing halves (1, 2), divides the interior of the housing into a suction chamber (5) and a pressure chamber (6). Suction nozzle parts (7) and pressure nozzle parts (8) attached to the intermediate wall (3) are arranged alternately with respect to the joining plane (4). In the exemplary embodiment shown here, the integrally formed, longitudinally divided and channel-shaped suction nozzle part (7) is located above the joining plane (4) and extends completely into the suction nozzle (9) formed by the two housing halves. The correspondingly designed pressure connection part (8) lies in the exemplary embodiment below the joining plane (4) and within the pressure connection (10). An opening (11) made within the intermediate wall (3) enables an overflow from the suction chamber into the pressure chamber, wherein the opening (11) can be followed by an impeller or - as shown in dashed lines - a step housing (12). To attach the same, the upper housing half (1) has a central opening (13), which can be easily manufactured using a simple punching tool.

Die in der Fügeebene angeordnete Zwischenwand ermöglicht einen direkten Kraftschluß zwischen Saug- und Druckstutzen, wobei die Einbeziehung der an der Zwischenwand angebrachten Stutzenteile in die am Gehäuse angebrachten Stutzen ein festigkeitsmäßiges Optimum darstellt.The intermediate wall arranged in the joining plane enables direct frictional connection between the suction and pressure ports, the inclusion of the connector parts attached to the intermediate wall in the connectors attached to the housing representing an optimum in terms of strength.

Die Fig. 2 zeigt eine Draufsicht auf das Gehäuse in Inline-­Bauart, insbesondere auf die Gehäusehälfte (1), deren Öffnung (13) mit der darunterliegenden Zwischenwand (3) und der darin angebrachten Öffnung (11).Fig. 2 shows a plan view of the housing in-line design, in particular on the housing half (1), the opening (13) with the underlying partition (3) and the opening (11) made therein.

Die Fig. 3 entspricht einem Schnitt III-III aus Fig. 1. In der Fügeebene (4) befindet sich die Zwischenwand (3), an der die beiden Gehäusehälften (1, 2) anliegen. Im Bereich der Zwischenwand weisen die Gehäusehälften kleine Flanschflächen (14) auf, mit deren Hilfe die gezeigten Teile durch Schweißen, Kleben, Löten oder dgl. fest verbunden werden können. Bei einem eventuellen Verschweißen der Teile können die aus dem Gehäuse hervorstehenden Teile der Zwischenwand (3) sowie der Flanschflächen (14) als Material für die Schweißnaht benutzt werden.3 corresponds to a section III-III from FIG. 1. In the joining plane (4) there is the intermediate wall (3) against which the two housing halves (1, 2) rest. In the area of the intermediate wall, the housing halves have small flange surfaces (14) by means of which the parts shown can be firmly connected by welding, gluing, soldering or the like. If the parts are welded together, the parts of the partition (3) and the flange surfaces (14) protruding from the housing can be used as material for the weld seam.

Fig. 4 und 5 entspricht einem Schnitt gemäß den Schnittebenen IV-IV und V-V aus Fig. 1. Hierbei ist gemäß Fig. 4 erkennbar, wie Strömungsgünstig der an der Zwischenwand (3) angeformte Saugstutzenteil (7) innerhalb des von den beiden Gehäuse­hälften (1, 2) gebildeten Saugstutzens angeordnet ist. Gemäß Fig. 5 ist der gegenüber Fig. 4 wechselseitige Verlauf des an der Zwischenwand (3) angebrachten Druckstutzenteiles (8) erkennbar. Es ist hier nach unten ausgeformt, um so einen Ausfluß aus dem Druckraum in den Druckstutzen (10) zu ermöglichen. Infolge der erfindungsgemäßen Ausbildung der Zwischenwand ist sichergestellt, daß beim Fügevorgang der Gehäusehälften auch gleichzeitig eine flüssigkeitsdichte Verbindung zwischen Saug- und Druckraum erfolgt.4 and 5 corresponds to a section along the sectional planes IV-IV and VV from FIG. 1. Here it can be seen from FIG. 4 how flow-favorably the suction nozzle part (7) formed on the intermediate wall (3) within the two halves of the housing ( 1, 2) suction port is arranged. According to FIG. 5, the mutual course of the pressure nozzle part (8) attached to the intermediate wall (3) can be seen. It is shaped downwards so as to allow an outflow from the pressure chamber into the pressure port (10). As a result of the design of the intermediate wall according to the invention, it is ensured that, during the joining process of the housing halves, there is also a liquid-tight connection between the suction and pressure chambers.
