Description

Laufrad für selbstansaugende Wasserring- und Vakuumpumpen Die Laufräder (Laufsterne) von selbstansaugenden Wasserringpumpen gehen sehr leicht zu Bruch, wenn Fremdkörper von gewisser Härte und Größe unglücklicherweise so in die Pumpe eindringen, daß sie sich zwischen die Eintrittsöffnung in der Gehäusewand und eine Laufradschaufel einklemmen; in diesem Falle bricht die Laufradschaufel ab und wird ebenfalls zum Fremdkörper. Die Folge ist dann, daß in einer Art Kettenreaktion sämtliche Laufradflügel zu Bruch gehen.Impeller for self-priming water ring and vacuum pumps The impellers (Catwalk stars) of self-priming water ring pumps break very easily, if foreign objects of a certain hardness and size unfortunately get into the pump penetrate that they are between the inlet opening in the housing wall and a Pinch the impeller blade; in this case the impeller blade breaks off and becomes also to the foreign body. The result is that in a kind of chain reaction all of them Impeller blades break.

Diese Gefahr besteht auch bei den bekannten Laufrädern mit einem Versteifungsring zwischen Außenumfang und Schaufelwurzel.This danger also exists with the known impellers with a stiffening ring between the outer circumference and the blade root.

Mit der Erfindung soll dieser Nachteil vermieden werden.This disadvantage is to be avoided with the invention.

Es hat sich nämlich gezeigt, daß der bekannte Versteifungsring bei geeigneter Anordnung zum Einklemmen der Fremdkörper verwendet werden kann, bevor der Fremdkörper einen Schaufelbruch verursacht.It has been shown that the well-known stiffening ring at suitable arrangement for pinching the foreign body can be used before the foreign body causes the blade to break.

Demgemäß besteht die erfinderische Neuerung darin, daß der Versteifungsring genau in der Höhe der Öffnung des Pumpengehäuses angeordnet ist, durch welche das Fördergut und der eventuell mitgeführte Fremdkörper eintritt.Accordingly, the inventive innovation is that the stiffening ring is arranged exactly at the level of the opening in the pump housing through which the The conveyed goods and any foreign objects that may be carried with them enter.

Zur Erprobung der Erfindung wurden dem Fördergut gußeiserne Fremdkörper in der Größe von 1/z bis 1 qcm in der Fläche und 2 bis 3 mm Stärke beigemengt, die zum Teil in die Pumpe gelangten. Es wurde dabei festgestellt, daß in keinem Falle die Schaufeln des Laufrades abbrachen. Der Fremdkörper klemmt sich jedesmal zwischen eine Laufradschaufel und eine Gehäuseöffnung ein und blockierte die Pumpe.To test the invention, cast-iron foreign bodies were found in the conveyed material in the size of 1 / z to 1 square cm in the area and 2 to 3 mm thickness added, the partly got into the pump. It was found that in no case the blades of the impeller broke off. The foreign body gets stuck between each time an impeller vane and a housing opening and blocked the pump.

Nach Entfernung des Eindringlings und Entgratung der Schaufel war das Laufrad noch voll verwendungsfähig. Durch die Erfindung werden die häufig auftretenden Schaufelbrüche vermieden. Außerdem wird die Pumpe betriebssicherer, und ihre Lebensdauer wird erhöht.After removing the intruder and deburring the shovel was the impeller is still fully usable. With the invention, the frequently occurring Avoided blade breakage. In addition, the pump becomes more reliable and its service life will be raised.

In der Zeichnung ist das Laufrad durch Abb. 1 in der Draufsicht dargestellt. Abb. 2 zeigt dasselbe im Schnitt.In the drawing, the impeller is represented by Fig. 1 in plan view. Fig. 2 shows the same in section.

In Abb. 3 wird gezeigt, wie das Laufrad im Sauggehäuse der Pumpe läuft. Hierbei ist auch die Eintrittsöffnung im Sauggehäuse durch den Buchstaben a kenntlich gemacht, und außerdem wird dabei dargestellt, daß der Versteifungsring b in der Höhe der Eintrittsöffnung liegt.Fig. 3 shows how the impeller runs in the suction casing of the pump. The inlet opening in the suction housing can also be identified by the letter a made, and it is also shown that the stiffening ring b in the Height of the inlet opening.

Abb. 4 zeigt einen Schnitt durch Gehäuse und Laufrad der Pumpe; hier ist nochmals die Lage des Versteifungsringes zu der Eintrittsöffnung übersichtlich dargestellt.Fig. 4 shows a section through the housing and impeller of the pump; here the position of the stiffening ring to the inlet opening is again clear shown.

Das Profil und andere Formen des Versteifungsringes können je nach Verwendungszweck der Pumpe spitzoval, oval, kreisrund, drei- oder viereckig gestaltet werden.The profile and other shapes of the stiffening ring can vary depending on Purpose of the pump with a pointed oval, oval, circular, triangular or square shape will.
