Description
Schrauben- oder Propellerpumpe Vorliegende Erfindung betrifft Schrauben-oder Propellerpumpen, welche gemäß Patent 500 266 mit an ihrer Vorderseite rückwärts gerichteten oder rückwärts gekrümmten Flügeln ausgerüstet sind, damit Schlingpflanzen, Holzspäne u. dgl. von den Flügelkanten nach außen geschoben werden, wo sie durch den Spalt, der zwischen Gehäusewand und Flügelende vorhanden ist, entweichen können.Screw or propeller pump The present invention relates to screw or propeller pumps Propeller pumps, which according to patent 500 266 with at their front backwards pointed or backward curved wings are equipped so that creepers, Wood shavings and the like are pushed outward from the wing edges, where they are pushed through the gap between the housing wall and the wing tip can escape.
Bei derartigen Pumpen ist beobachtet worden, daß bisweilen Holzstücke u. dgl. sich zwischen Flügelende und Gehäusewand festsetzen und kurze Geit vom Flügel mit herumgeschleift werden. Der Elektromotor ist dann überlastet, und der Schutzschalter schaltet aus. Um diesem Übelstande abzuhelfen, werden entweder an--der Stelle,--wo der Propeller läuft, in der Gehäusewand einige Nuten a a (Abb. i) oder einige Rippen h b (Abb. 2) angebracht, oder es werden die äußeren Flügelenden, wie in Abb.3 dargestellt, so gestaltet, daß der zwischen ihnen und der Geli'-iusewand verbleibende "Zwischenraum c an der voranlaufenden Seite des Flügels am engsten ist und nach rückwärts (in der Drehrichtung-) weiter wird.With pumps of this type it has been observed that pieces of wood and the like sometimes get stuck between the end of the wing and the housing wall and are dragged around by the wing for a short period of time. The electric motor is then overloaded and the circuit breaker switches off. In order to remedy this inconvenience, some grooves a a (Fig. I) or some ribs hb (Fig. 2) are made in the housing wall - at the point - where the propeller runs, or the outer wing tips, as shown in Fig.3, designed so that the "space c" remaining between them and the Geli'-iuse wall is narrowest on the leading side of the wing and widens backwards (in the direction of rotation-).
Die Maßnahmen gemäß Abb. i oder 2 können auch mit der Maßnahme gemäß Abb. 3 vereinigt werden, um eine noch bessere Wirkung zu erzielen.The measures according to Fig. I or 2 can also be used with the measure according to Fig. 3 can be combined to achieve an even better effect.
Fei der Ausgestaltung des Gehäuses oder der Flügel gemäß dieser Erfindung werden die Fremdkörper, welche sich zwischen Flügelende und Gehäuse festsetzen sollten, nur ein kleines Stück bis zur nächsten Nut oder Rippe mitgenommen. Dort stoßen ie an und «-erden vorn Flügel wieder losgelassen, tim vom Wasserstrom fortgespült ztt «-erden.Notwithstanding the design of the housing or wings in accordance with this invention the foreign bodies, which should get stuck between the wing tip and the housing, only taken a little bit to the next groove or rib. There you come across on and '- earth released again at the wing, washed away by the stream of water "-earth.
Wenn die äußeren Flügelenden scharf oder gezahnt, wie in Abb.2 angedeutet, ausgebildet werden oder mit. ihrer voranlaufenden Seite am dichtesten an die Gehäusewand herangehen (Abb. 3), kann bei der entslireclienden Ausbildung der Nuten oder Rippen ein Zerschneiden oder Zerreißen der Schlinggewächse erreicht «erden, wodurch der weitere Durchgang derselben durch einen etwa vorhandenen Leitapparat erleichtert oder (las Hängenbleiben dieser Fremdstoffe an Teilen der Pumpe, der Rückstauklappe o. (1-l. ver-Iii-n(1e.rt- o(fe-r- vermindert werden kann.If the outer wing tips are sharp or serrated, as indicated in Figure 2, be trained or with. its leading side closest to the housing wall approach (Fig. 3), can be used in the development of the grooves or ribs a cutting or tearing of the creeping plants can be achieved, whereby the further passage of the same facilitated by any existing diffuser or (read these foreign matter got stuck on parts of the pump, the backflow flap o. (1-l. ver-Iii-n (1e.rt- o (fe-r- can be reduced.
