Description

Die Erfindung betrifft eine Kreiselpumpe gemäß dem Oberbegriff des Anspruches 1.The invention relates to a centrifugal pump according to the preamble of claim 1.

Derartige Kreiselpumpen, welche für eventuelle Reparaturarbeiten eine sehr gute Zugänglichkeit aufweisen und überwiegend mit doppelflutigen Laufrädern ausgerüstet sind, verfügen übei ein längsgeteiltes Pumpengehäuse mit einer beiderseits gelagerten Welle. Infolge der unterhalb der Wellenebene angeordneten Saug- und Druckstutzen muß bei einer Inspektion oder Reparatur das Kreiselpumpengehäuse nicht aus der Rohrleitung ausgebaut werden. Durch Abheben des Gehäuseoberteiles sind die rotierenden Teile leicht zugänglich und können ohne Schwierigkeiten ausgebaut werden. Nachteilig bei dieser Bauart ist die Verbindung zwischen Pumpe und Motor, welche ein besonders stabiles Fundament, Rahmen oder dgl. sowie eine exakte Ausrichtung zwischen Pumpe und Motor erfordert, um einen zuverlässigen verschleißarmen Betrieb sicherzustellen.Centrifugal pumps of this type, which have very good accessibility for any repair work and are predominantly equipped with double-flow impellers, have a longitudinally divided pump housing with a shaft mounted on both sides. As a result of the suction and pressure ports arranged below the shaft level, the centrifugal pump housing does not have to be removed from the pipeline during an inspection or repair. By lifting the upper part of the housing, the rotating parts are easily accessible and can be removed without difficulty. A disadvantage of this type of construction is the connection between the pump and the motor, which requires a particularly stable foundation, frame or the like and an exact alignment between the pump and the motor in order to ensure reliable, low-wear operation.

Aus der FR-A 488 377 ist eine Kreiselpumpe mit parallel zur Wellenachse geteiltem Gehäuse bekannt. Das Saug- und Druckstutzen aufweisende Unterteil ist mit einer ebenfalls die Lager der Pumpenwelle tragenden Fundamentplatte versehen. Mittels der Fundamentplatte und insbesondere der Unterseite, ist eine Aufstellung der Pumpe am Montageort möglich.A centrifugal pump with a housing divided parallel to the shaft axis is known from FR-A 488 377. The lower part, which has suction and pressure ports, is provided with a base plate which also supports the bearings of the pump shaft. The pump can be installed at the installation location using the foundation plate and in particular the underside.

Die BE-A 385 893 zeigt ebenfalls ein längsgeteiltes Gehäuse. Das Gehäuseunterteil weist hierbei an seinen Stirnseiten Aufnahmeflächen für die Anbringung von Haltern der Wellenlagerungen auf. Zusätzlich vorgesehene Stützen (9) erlauben die Aufstellung des Gehäuses auf einem aus Doppel-T-Träger gebildeten Rahmen.BE-A 385 893 also shows a longitudinally divided housing. The lower part of the housing in this case has receiving surfaces on its end faces for the attachment of holders of the shaft bearings. Supports (9) additionally provided allow the housing to be set up on a frame formed from a double-T support.

Der Erfindung liegt die Aufgabe zugrunde, ein längsgeteiltes Pumpengehäuse in wenig aufwendiger Weise zur Ankoppelung eines Motors sowie vielseitiger Aufstellung der Pumpe auszubilden. Die Lösung dieser Aufgabe erfolgt gemäß dem kennzeichnenden Teil des Hauptanspruches.The invention has for its object to form a longitudinally divided pump housing in a less complex manner for coupling a motor and a versatile installation of the pump. This object is achieved in accordance with the characterizing part of the main claim.

Mittels dieser Lösung kann ein Motor in einfachster Weise mittel- oder unmittelbar an ein gattungsgemäßes Gehäuse angeflanscht werden. Bezeichnet man diejenigen Gehäuseseiten, an denen die Wellenlager vorgesehen sind, als die Gehäusestirnseiten, dann weisen diese im Bereich des Teilflansches sowie der Pumpenfüße Flächen auf, die bei einer Befestigung von zusätzlichen Teilen als Anlage dienen. Somit kann eine Motorlaterne am Gehäuseunterteil im Bereich des Teilflansches und den Pumpenfüßen mit einer Vierpunktanlage angeflanscht werden. Dadurch, daß die in Richtung der Wellenachse einander gegenüberliegenden Pumpenfüße eine Kräfte- und momenteübertragende Verbindung aufweisen, wird eine Verformung des Gehäuseunterteiles und damit eine Beeinträchtigung der Wellenlagerung weitgehend ausgeschlossen. Die Kräfte können somit direkt auf der anderen Gehäusestirnseite in ein Fundament, Rahmen oder dgl. abgeleitet werden. Infolge der ausschließlichen Befestigung am Gehäuseunterteil wird der Vorteil von längsgeteilten Pumpengehäusen unverändert aufrechterhalten. Im Falle einer Inspektion oder dgl. kann das Gehäuseunterteil mit seinen Anschlußflanschen direkt in der Rohrleitung verbleiben, der am Gehäuseunterteil angeflanschte Motor braucht nicht entfernt zu werden und trotzdem besteht die Möglichkeit der problemlosen Gehäuseöffnung. Die kräfte- und momenteübertragende Verbindung der in Richtung der Wellenachse einander gegenüberliegenden Pumpenfüße kann derart sein, daß diese paarweise als einteiliges Gußstück ausgebildet sind. Somit besteht die Möglichkeit einer direkten geradlinigen Kräfteübertragung. Ein ganz speziell für diese Möglichkeit ausgerüstetes Gehäuse ist nicht erforderlich. Vielmehr kann ein mit derartigen Flächen versehenes Gehäuseunterteil für alle Anwendungsfälle, z. B. der üblichen horizontalen Aufstellung Verwendung finden. Mit einfachen Mitteln ergibt sich somit ein Pumpengehäuse mit der Möglichkeit einer vielseitigeren Aufstellung.With this solution, a motor can be flange-mounted in the simplest way, directly or indirectly, onto a generic housing. If those housing sides on which the shaft bearings are provided are referred to as the housing end faces, then they have surfaces in the region of the partial flange and the pump feet, which serve as an attachment when additional parts are attached. A motor lantern can thus be attached to the lower part of the housing in the area of the partial flange and the pump feet are flanged with a four-point system. Due to the fact that the pump feet lying opposite each other in the direction of the shaft axis have a force and torque transmitting connection, a deformation of the lower housing part and thus an impairment of the shaft bearing is largely excluded. The forces can thus be derived directly on the other end of the housing into a foundation, frame or the like. As a result of the exclusive attachment to the lower housing part, the advantage of longitudinally divided pump housings is maintained unchanged. In the event of an inspection or the like, the lower housing part with its connecting flanges can remain directly in the pipeline, the motor flanged to the lower housing part does not have to be removed and nevertheless there is the possibility of problem-free opening of the housing. The force and torque transmitting connection of the pump feet opposite each other in the direction of the shaft axis can be such that these are designed in pairs as a one-piece casting. Thus there is the possibility of a direct linear transmission of forces. A housing specially equipped for this possibility is not necessary. Rather, a housing base provided with such surfaces can be used for all applications, e.g. B. find the usual horizontal use. With simple means, this results in a pump housing with the possibility of a more versatile installation.

Eine andere erfindungsgemäße Lösung sieht vor, daß an Pumpenfüßen und/oder an Saug- und Druckstutzen bei einer Befestigung als Anlage dienende Flächen angebracht sing, daß die Flächen innerhalb von die Wellenachse schneidenden und senkrecht dazu verlaufenden Ebenen angebracht sind und daß bei in Richtung der Wellenachse einander gegenüberliegenden Pumpenfüßen eine kräfte- und momenteübertragende Verbindung besteht. Damit ist es möglich, einen Motor mittel- oder unmittelbar im Bereich der Saug- und Druckstutzen des Gehäuseunterteiles zu befestigen. Durch eine entsprechende Ausbildung der Flansche von den Saug- und Druckstutzen kann ein einfachster Weise eine Montage erfolgen.Another solution according to the invention provides that surfaces attached to the pump feet and / or to suction and pressure ports for attachment as an attachment are attached, that the surfaces are located within planes that intersect the shaft axis and run perpendicularly thereto, and that in the direction of the shaft axis opposite pump feet there is a force and torque transmitting connection. This makes it possible to attach a motor directly or indirectly in the area of the suction and pressure ports of the lower housing part. An appropriate design of the flanges from the suction and pressure ports allows for an easy installation.

Eine Ausgestaltung der Erfindung sieht vor, daß die Flächen jeweils einander paarweise gegenüberliegen. Dies ermöglicht eine einfache Fertigung sowie einen idealen Kräfte- und Momentefluß.An embodiment of the invention provides that the surfaces are opposite each other in pairs. This enables simple production and an ideal flow of forces and moments.

Eine weitere Ausgestaltung der Erfindung sieht vor, daß am Gehäuseunterteil im Bereich des Teilflansches angebrachte Materialanhäufungen Bestandteil der Flächen sind. Insbesondere bei gegossenen Gehäusen Können durch einfache gußtechnische Gestaltung größere Flächen und somit ein Maximum hinsichtlich der aufzunehmenden Belastungen verwirklicht werden. Bei Schweißkonstruktionen lassen sich derartige Flächen ebenfalls in einfacher Weise anbringen. Desweiteren ergibt sich somit die Möglichkeit, für eine Befestigung genormte Elemente, z. B. Profilstähle u. ä. Anwendung finden zu lassen.A further embodiment of the invention provides that material accumulations attached to the lower housing part in the region of the partial flange form part of the surfaces. In particular in the case of cast housings, larger areas and thus a maximum with regard to the loads to be absorbed can be realized by simple casting design. Such surfaces can also be attached in a simple manner to welded constructions. Furthermore, there is thus the possibility of attaching standardized elements, for. B. section steels u. to have application.

Wiederum eine andere Ausgestaltung sieht vor, daß in Richtung der Wellenachse einander gegenüberliegende Pumpenfüße durch Einsätze, Paßstücke oder dgl. kräfte- und momenteübertragend miteinander verbunden sind. Somit kann durch einfaches Einfügen von Zwischenstücken eine starre Verbindung zwischen zwei Pumpenfüßen erlangt werden, und wobei mittels einer weiteren Ausgesaltung, derzufolge die Pumpenfüße mit Öffnungen für Zuganker versehen sind, ein Zusammenspannen der zu befestigenden Teile erreicht werden. Anstelle der Zuganker ist es auch möglich, die Flächen mit Befestigungsmitteln zu versehen, um somit, beispielsweise die Traglaterne eines Motors direkt an den Flächen zu befestigen.Yet another embodiment provides that pump feet lying opposite one another in the direction of the shaft axis are connected to one another in a force-transmitting and torque-transmitting manner by inserts, fitting pieces or the like. A rigid connection between two pump feet can thus be achieved by simply inserting intermediate pieces, and the parts to be fastened can be clamped together by means of a further configuration, according to which the pump feet are provided with openings for tie rods. Instead of the tie rods, it is also possible to provide the surfaces with fastening means in order to fasten, for example, the support lantern of a motor directly to the surfaces.

Die Darstellung der Fig. 1 zeigt ein Kreiselpumpengehäuse (1), welches aus einem Gehäuseoberteil (2) und einem Gehäuseunterteil (3) besteht. Teilflansche (4) verbinden die beiden Gehäusehälften. Das Gehäuseunterteil (3) weist einen Saugstutzen (5), einen Druckstutzen (6) sowie daran angebrachte Pumpenfüße (8, 9) auf. Desweiteren weist das Gehäuseunterteil im Bereich der Teilflansche Flächen (10, 11) und an den Pumpenfüßen Flächen (12, 13) auf. Diese Flächen befinden sich in einer die Wellenachse (14) schneidenden und senkrecht dazu verlaufenden Ebene. Dabei können die Flächen (10 bis 13) sowohl in zwei als auch in mehreren parallel zueinander verlaufenden Ebenen angeordnet sein. Ein an das Gehäuseunterteil mittelbar oder unmittelbar zu befestigender, hier nicht gezeigter Motor gelangt an diesen Flächen zur Anlage. Befestigungsmittel (15), hier Gewindelöcher, erleichtern die direkte Anbringung an diesen Flächen. In den Pumpenfüßen (8, 9) angeordnete Öffnungen (16) erlauben eine Befestigung mittels durchgesteckter Zuganker. Diese können auch neben den Pumpenfüßen angeordnet sein.1 shows a centrifugal pump housing (1) which consists of an upper housing part (2) and a lower housing part (3). Partial flanges (4) connect the two housing halves. The lower housing part (3) has a suction nozzle (5), a pressure nozzle (6) and pump feet (8, 9) attached to it. Furthermore, the lower housing part has surfaces (10, 11) in the area of the partial flanges and surfaces (12, 13) on the pump feet. These surfaces are located in a plane that intersects the shaft axis (14) and runs perpendicular to it. The surfaces (10 to 13) can be arranged in two or in several planes running parallel to one another. A motor, not shown here, to be attached directly or indirectly to the lower housing part comes to rest on these surfaces. Fastening means (15), here threaded holes, facilitate direct attachment to these surfaces. Openings (16) arranged in the pump feet (8, 9) allow attachment by means of inserted tie rods. These can also be arranged next to the pump feet.

Die Fig. 2, welche eine Draufsicht auf das Gehäuseunterteil (3) darstellt, zeigt in strichpunktierter Darstellung zwei Ebenen (16, 17), innerhalb derer die Flächen (10 bis 13) liegen. Es ist ohne weiteres möglich, daß die an den Pumpenfüßen (8, 9) angebrachten Flächen (12, 13) in den gleichen oder parallel dazu verlaufenden anderen Ebenen liegen. An den im Bereich der Gehäusestirnseiten befindlichen Flanschflächen (18, 19) können die Pumpenwelle tragende Lagergehäuse angesetzt werden. Eine Lageranordnung innerhalb des Gehäuses ist möglich. Die im Bereich des Teilflansches (4) befindlichen Flächen (10, 11) sind hier Bestandteil von Materialanhäufungen (22), welche bei einem Gußgehäuse in einfacher Weise mit angegossen werden können. Es ist auch möglich, die Flächen (10 bis 13) an den Saug- und Druckstutzen (5, 6) zusätzlich oder ausschließlich vorzusehen, um somit weitere Befestigungsmöglichkeiten für den Motor zu schaffen.2, which shows a plan view of the lower housing part (3), shows two levels (16, 17) in dash-dotted lines, within which the surfaces (10 to 13) lie. It is readily possible for the surfaces (12, 13) attached to the pump feet (8, 9) to lie in the same or other planes running parallel to them. Bearing housings that support the pump shaft can be attached to the flange surfaces (18, 19) located in the area of the housing end faces. A bearing arrangement within the housing is possible. The surfaces (10, 11) located in the region of the partial flange (4) are part of material accumulations (22) which can be cast on in a cast housing in a simple manner. It is also possible to use the surfaces (10 to 13) on the suction and pressure ports (5, 6) additionally or exclusively to provide additional mounting options for the engine.

Die Fig. 3 zeigt ein vertikal aufgestelltes und mit einem Motor (20) vershens Pumpengehäuse (1). Mit Hilfe einer Laterne (21) ist der Motor (20) mit den Flächen (10 bis 13) des Gehäuseunterteiles gekoppelt. An der einen Gehäusestirnseite ist die Laterne (21) befestigt, während die Pumpe mit der anderen Gehäusestirnseite auf U-Trägern (23) aufliegt, welche mit einem Fundament (24) verbunden sind. Im Bereich der Teilflansche erfolgt eine Verbindung zwischen Laterne (21) und Trägern (23) mittels Befestigungsmitteln (15), hier Schrauben, die in Gewindebohrungen der Flächen (10, 11) hineingreifen. Im Bereich der Pumpenfüße (8), die mit dem Gehäuseunterteil als einteiliges Gußteil ausgebildet und so untereinander kräfteübertragend verbunden sind, erfolgt ein Zusammenhalt der Teile mittels Zuganker (25), welche die Laterne (21), die Pumpenfüße (8) und die Träger (23) zusammenspannen.Fig. 3 shows a vertically installed and provided with a motor (20) pump housing (1). The motor (20) is coupled to the surfaces (10 to 13) of the lower housing part with the aid of a lantern (21). The lantern (21) is attached to one end of the housing, while the pump rests with the other end of the housing on U-beams (23), which are connected to a foundation (24). In the area of the partial flanges, a connection is made between the lantern (21) and the supports (23) by means of fastening means (15), here screws, which engage in threaded holes in the surfaces (10, 11). In the area of the pump feet (8), which are formed as a one-piece cast part with the lower housing part and are thus connected to each other in a force-transmitting manner, the parts are held together by means of tie rods (25) which hold the lantern (21), the pump feet (8) and the supports ( 23) clamp together.
