Description
Zahnradpumpe für ätzende Flüssigkeiten Verwendet man Zahnradpumpen zum Fördern von ätzenden Flüssigkeiten, so leiden ganz besonders die die Eingriffslinie beider Zahnräder seitlich begrenzenden Teile der Maschine. Es bildet sich längs der Zähne in der Breite zwischen Fuß- und Kopflinie eine sich allmählich vertiefende Rinne, die einen Durchgang zwischen Saug- und Druckseite der Pumpe schafft. Der Wirkungsgrad der Maschine nimmt infolgedessen beim Gebrauch ab.Gear pump for corrosive liquids. Gear pumps are used for pumping corrosive liquids, the line of action suffer particularly of both gears laterally limiting parts of the machine. It forms lengthways of the teeth in the width between the foot and head line a gradually deepening Channel that creates a passage between the suction and pressure side of the pump. Of the As a result, the efficiency of the machine decreases with use.
Gegenstand der Erfindung ist eine Zahnradpumpe für ätzende Flüssigkeiten, wie beispielsweise gewisse Celluloselösungen, welche die obengenannten Übelstände nicht aufweist, da die die Eingriffslinie der Zahnräder beidseitig derselben begrenzenden Teile des Gehäuses aus einem besonderen widerstandsfähigen Baustoff gemacht sind, so daß auch nach einer längeren _ Gebrauchsdauer die Dichtigkeit der Pumpe, also auch ihr Nutzeffekt, stets gleich ist.The invention relates to a gear pump for corrosive liquids, such as certain cellulose solutions, which have the above-mentioned inconveniences does not have, since the line of engagement of the gears on both sides of the same delimiting Parts of the housing are made of a particularly resistant building material, so that even after a longer period of use, the tightness of the pump, i.e. also its usefulness is always the same.
Auf der Zeichnung ist beispielsweise eine Pumpe, welche erfindungsgemäß gebaut ist, in Längsschnitt (Abb. i) und Ansicht (Abb.2) dargestellt.The drawing shows, for example, a pump which, according to the invention is built, shown in longitudinal section (Fig. i) and view (Fig. 2).
Die Pumpe ist von derjenigen Art, bei welcher eine der genauen Breite der Räder entsprechende Mittelplatte i zwischen Seitenteil 2 und Deckel 3 vorgesehen ist mit einer Öffnung 6, worin das treibende Zahnrad .4 und das getriebene, 5, untergebracht sind.The pump is of the type with one of the exact width the center plate i corresponding to the wheels is provided between side part 2 and cover 3 is with an opening 6, in which the driving gear .4 and the driven, 5, housed are.
Die den Raum 7, in welchem der Eingriff der Zahnräder erfolgt, seitlich begrenzenden Teile der Maschine sind durch Scheibenringe 2o aus unätzbarem Stoff, wie beispielsweise rotsfreier Stahl, gebildet. Diese Scheibenringe sind in Vertiefungen io und i i des Seitenteils und des Deckels eingelassen. Hierdurch ist die Möglichkeit geschaffen, durch zeitweises Drehen des Ringes etwa dennoch eintretende Anfressungen auszuschalten.The space 7, in which the engagement of the gears takes place, laterally delimiting parts of the machine are made of non-etchable material by 2o washer rings, such as red-free steel. These disc rings are in recesses io and i i of the side part and the lid let in. This makes the possibility created, by occasionally turning the ring, any cracks occurring anyway turn off.
