MotorkreiselpumpeMotor centrifugal pump

Die vorliegende Erfindung betrifft eine Motorkreiselpumpe, insbesondere als Brauchwasserzirkulationspumpe mit einem am Elektromotor befestigten Pumpengehäuse mit Ein- und Auslass.The present invention relates to a motor centrifugal pump, in particular as a service water circulation pump with a pump housing with inlet and outlet attached to the electric motor.

Es ist bekannt, am Ein- und Auslass des Gehäuses einer Motorkreiselpumpe jeweils ein Rohrverbindungselement anzuschrauben, das ein Absperrorgan enthält und an dem durch eine Überwurfmutter das Anschlussrohr der jeweiligen Rohrleitung befestigbar ist. Eine solche Vorrichtung wird in mehreren Teilen angeliefert, so dass für den Benutzer, insbesondere für den Installateur ein erheblicher Arbeitsaufwand für die Montage erforderlich ist.It is known to screw a pipe connection element onto the inlet and outlet of the housing of a motor-driven centrifugal pump, which contains a shut-off device and to which the connecting pipe of the respective pipeline can be attached using a union nut. Such a device is delivered in several parts, so that the user, especially the installer, has to put in a lot of work to assemble it.

Aufgabe der Erfindung ist es, eine Motorkreiselpumpe der eingangs genannten Art so zu verbessern, dass der Montageaufwand erheblich verringert ist.The object of the invention is to improve a motor centrifugal pump of the type mentioned above in such a way that the assembly effort is considerably reduced.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, dass am Ein- und/oder Auslass ein Rohrverbindungselement unlösbar befestigt ist, an dem das Ansaugrohr befestigbar ist und das ein Ventil (Absperrorgan), insbesondere eine Absperrvorrichtung und/oder eine Rückflussverhinderungsvorrichtung enthält.This object is achieved according to the invention in that a pipe connection element is permanently attached to the inlet and/or outlet, to which the intake pipe can be attached and which contains a valve (shut-off device), in particular a shut-off device and/or a backflow prevention device.

Hierdurch bilden die Rohrverbindungselemente einschließlich der darin angeordneten Absperrorgange mit dem Pumpengehäuse bzw. der Pumpe eine Einheit, so dass ein kompaktes Aggregat vorliegt, das nur noch an die Rohrenden angeschlossen werden muss. Es brauchen keine Rohrverbindungselemente bzw.As a result, the pipe connection elements, including the shut-off devices arranged therein, form a unit with the pump housing or pump, so that a compact unit is available that only needs to be connected to the pipe ends. No pipe connection elements or shut-off devices are required.

Fittings am Pumpengehäuse vom Monteur angeschlossen zu werden, sondern das fertige Kompaktaggregat ist nur noch an den Leitungen zu befestigen.Fittings on the pump housing do not need to be connected by the fitter, but the finished compact unit only needs to be attached to the lines.

Vorzugsweise wird hierbei vorgeschlagen, dass das Rohrverbindungselement durch Pressitz, Löten, Schweißen oder Kleben befestigt ist. Besonders vorteilhaft ist es, wenn das Pumpengehäuse aus Kunststoff und das Rohrverbindungselement aus Kunststoff oder Metall ist.Preferably, it is proposed that the pipe connection element is attached by means of a press fit, soldering, welding or gluing. It is particularly advantageous if the pump housing is made of plastic and the pipe connection element is made of plastic or metal.

Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung im Schnitt dargestellt und wird im folgenden näher beschrieben.An embodiment of the invention is shown in section in the drawing and is described in more detail below.

Am Pumpengehäuse 1 ist auf einer Seite durch eine Überwurfmutter 2 ein Elektromotor 3 angeschraubt. Die den Pumpenmotor aufweisende Pumpenkammer ist nicht dargestellt, sondern durch die Überwurfmutter 2 verdeckt.An electric motor 3 is screwed to one side of the pump housing 1 by means of a union nut 2. The pump chamber containing the pump motor is not shown but is covered by the union nut 2.

Das Pumpengehäuse 1 bildet einen zur Pumpenkammer führenden Einlasskanal 4 und einen von der Pumpenkammer ausgehenden Auslasskanal 5. Der Einlasskanal 4 endet an einem Gehäuseeinlassstutzen 6 und der Auslasskanal an einem Gehäuseauslassstutzen 7. In den Einlassstutzen 6 ist ein Rohrverbindungselement 8 und in den Auslassstutzen 7 ein Rohrverbindungselement 9 eingesteckt, wobei das verjüngte Ende des jeweiligen Rohrverbindungselements 8, 9 eine Ringdichtung 10 aufweist, mit der das jeweils verjüngte Ende im Einlassstutzen bzw. Auslassstutzen einliegt. Der Halt dieses Rohrverbindungselements am Pumpengehäuse ist jeweils durch Pressitz, Löten oder Schweißen gegeben.The pump housing 1 forms an inlet channel 4 leading to the pump chamber and an outlet channel 5 extending from the pump chamber. The inlet channel 4 ends at a housing inlet connection 6 and the outlet channel at a housing outlet connection 7. A pipe connection element 8 is inserted into the inlet connection 6 and a pipe connection element 9 is inserted into the outlet connection 7, the tapered end of the respective pipe connection element 8, 9 having a ring seal 10 with which the respective tapered end lies in the inlet connection or outlet connection. This pipe connection element is held on the pump housing by a press fit, soldering or welding.

Das erste Rohrverbindungselement 8 am Einlassstutzen 6 enthält ein Absperrorgan 11, und das zweite Rohrverbindungselement 9 am Auslassstutzen 7 enthält ein Rückschlagventil 12. Bei jedem der beiden Rohrverbindungselemente ist das dem Pumpengehäuse 1 abgewandte Ende mit einem Wulst mit einliegender Ringdichtung versehen, so dass nach Einstecken des Anschlussrohres 13 bzw. 14 dieses durch Verpressen gehalten ist.The first pipe connection element 8 on the inlet connection 6 contains a shut-off device 11, and the second pipe connection element 9 on the outlet connection 7 contains a check valve 12. In each of the two pipe connection elements, the end facing away from the pump housing 1 is provided with a bead with an inset ring seal, so that after the connecting pipe 13 or 14 is inserted, it is held by pressing.

Das Pumpengehäuse 1 besteht vorzugsweise aus Kunststoff und die Rohrverbindungselemente 8,9 aus Metall.The pump housing 1 is preferably made of plastic and the pipe connecting elements 8,9 are made of metal.
