KAISERLICHESIMPERIAL
PATENTAMT.PATENT OFFICE.
Bei Zentrifugalpumpe]! mit eingesetzten Leitapparaten kann der Fall eintreten, daß die 'Leitapparate infolge von Inkrustationen, wie sie durch kalk- oder kieselsäurehaltiges Wasser hervorgerufen werden, im Gehäuse sich derart festsetzen, daß ■ sie nur schwer und mit großer Mühe sich wieder losbringen lassen.With centrifugal pump]! with inserted guide devices It can happen that the 'diffusers as a result of incrustations, such as those caused by calcium or silicic acid Water caused, settle in the housing in such a way that ■ they are difficult and let go again with great effort.
Die vorliegende Erfindung soll diesen Übelstand beseitigen und besteht darin, daß die Leitapparate mit den übrigen eingesetzten Teilen von einem Mantel umschlossen sind, der in seiner Längsrichtung geteilt und nur mit einem Teil seiner äußeren Fläche in das Pumpengehäuse eingepaßt ist. Die Berührungsfläche zwischen dem Mantel und dem äußeren Gehäuse ist klein bemessen; der Mantel läßt sich daher leicht herausnehmen.The present invention is intended to remedy this drawback and is that the Distributors with the other parts used are enclosed by a jacket, which is divided in its longitudinal direction and only with part of its outer surface in the Pump housing is fitted. The interface between the jacket and the outer one Housing is small in size; the coat can therefore be easily removed.
Die Erfindung ist auf der beiliegendenThe invention is on the enclosed
.20 Zeichnung in einem Ausführungsbeispiel zur Veranschaulichung gebracht..20 drawing brought in an exemplary embodiment for illustration.
Die Laufräder der Pumpe sind mit a, die Leitapparate mit b bezeichnet, die Zwischenstücke, die die Uberströmkanäle enthalten, mit c und das äußere Gehäuse mit d. Zwischen das Gehäuse d und die inneren Teile der Pumpe ist der aus zwei oder mehreren Teilen e1, e2 usw. bestehende Mantel e eingesetzt, der durch den Deckel h auf seine Sitzflächen f und g gepreßt wird. Die kleinen Räume k und I werden zweckmäßig durch Dichtungsschnüre abgedichtet.The impellers of the pump are designated with a, the diffusers with b , the intermediate pieces containing the overflow channels with c and the outer housing with d. The jacket e , which consists of two or more parts e 1 , e 2 , etc., is inserted between the housing d and the inner parts of the pump and is pressed through the cover h onto its seating surfaces f and g. The small spaces k and I are expediently sealed by sealing cords.
Soll die Pumpe auseinandergenommen werden, so braucht der Mantel e. nach Entfernung des Deckels h nur von seinen Sitzflächen losgelöst und herausgezogen zu werden; die Leitapparate lassen sich dann nach Abheben des Mantels bequem voneinander trennen, und zwar ohne daß Druckschrauben, wie sie bisher zur Herausnahme der eingesetzten Teile bei Zentrifugalpumpen notwendig waren, dazu erforderlich sind.If the pump is to be taken apart, the jacket needs e. after removal of the cover h can only be detached from its seat surfaces and pulled out; the diffusers can then be easily separated from one another after the casing has been lifted off, without the need for pressure screws, as were previously necessary to remove the parts used in centrifugal pumps.
Die Berührungsflächen zwischen dem Mantel e und dem äußeren Gehäuse können beliebiger Art sein; bei entsprechender Ausbildung des Gehäuses können sie auch in die Pumpendeckel verlegt werden. ■■ Der Mantel e kann anstatt, wie auf der Zeichnung dargestellt, durch den hinteren Deckel h auch in anderer Weise fixiert sein.The contact surfaces between the jacket e and the outer housing can be of any type; If the housing is designed accordingly, they can also be relocated to the pump cover. ■■ The jacket e can instead of, as shown in the drawing, be fixed in another way by the rear cover h.
