Description

Verschleißfeste Kreiselpumpe, deren Gehäuse mit Gummi als Verschleißschutz ausgekleidet ist Die Hauptpatentanmeldung E17228 Ia/59b betrifft eine verschleißfeste Kreiselpumpe, vorzugsweise zur Förderung von grobem Fördergut, deren Gehäuse mit Gummi als Verschleißschutz ausgekleidet ist, wobei zwischen dem aus Gummi oder ähnlichem Material bestehenden Verschleißeinsatz und dem Pumpengehäuse ein Gas-, insbesondere Luftpolster angeordnet ist.Wear-resistant centrifugal pump, the housing of which is lined with rubber as protection against wear Pump housing a gas, in particular air cushion is arranged.

Die dort angegebene Ausbildung und Halterung des Verschleißeinsatzes wird durch die vorliegende Erfindung verbessert und vereinfacht.The training and mounting of the wear insert specified there is improved and simplified by the present invention.

Nach der zusätzlichen Erfindung besteht derVerschleißeinsatz am spiralförmigen Pumpenumfang aus mehreren nebeneinanderliegenden, verankerten Profilstreifen. Vorzugsweise erfolgt die Verankerung derart, daß die Verschleißprofile am Pumpenumfang mit vorzugsweise T-förmigen Profilleisten verankert und verzahnt sind. An sich ist die Fertigung von Spiralgehäusen für Pumpen aus einzelnen Materialscheiben bekannt.According to the additional invention, the wear insert is on the spiral Pump circumference made up of several anchored profile strips lying next to one another. Preferably the anchoring takes place in such a way that the wear profiles on the pump circumference with preferably T-shaped profile strips are anchored and interlocked. In itself is manufacturing known from volute casings for pumps made of individual material disks.

Hierbei übernehmen die der Spiralform des Pumpengehäuses entsprechend gebogenen T-förmigen Stahlprofile sowohl die sichere Halterung des Gummi-Verschleißkörpers gegen auftretendes Vakuum wie auch die unbedingt erforderliche Abstandshaltung gegenüber dem äußeren Pumpengehäuse, so daß der Luftraum hinter dem Verschleißeinsatz sicher erhalten bleibt.Here, they take over the spiral shape of the pump housing curved T-shaped steel profiles both securely hold the rubber wear body against occurring vacuum as well as the absolutely necessary distance from it the outer pump housing, so that the air space behind the wear insert is safe preserved.

Weiterhin ist durch die zusätzliche Erfindung die Herstellung des Einsatzes vereinfacht und verbilligt worden. Auch wird sein Einbau gegenüber der früheren Ausbildung erheblich vereinfacht, und es ist die Möglichkeit der Auswechselung schadhafter Streifen geschaffen worden.Furthermore, the production of the Use has been simplified and made cheaper. Also, its installation will be opposite the earlier training is greatly simplified, and there is the possibility of substitution defective stripe has been created.

In der Zeichnung, welche einen Schnitt durch die Pumpenwand mit Auskleidung darstellt, ist die Erfindung beispielsweise wiedergegeben. Es bedeutet darin 1 das Gehäuse der Pumpe, 2 die Profilteile des Gummi-Verschleißkörpers, 3 die T-förmigen Verbindungs- und Halteeisen, 4 den für das Luftpolster vorgesehenen Raum.In the drawing, which shows a section through the pump wall with lining represents, the invention is exemplified. In 1 it means that Housing of the pump, 2 the profile parts of the rubber wear body, 3 the T-shaped ones Connecting and holding iron, 4 the space provided for the air cushion.
