Description

Abdichtung der Querwelle bei Förderpumpen, insbesondere mit zwei parallel zueinander angeordneten Zylindern o Zusatz zum Patent 4715o9 Bei dem durch das Patent 471 509 in dein Druckraum von Förderpumpen. geschützten abgedichteten Raum, in dem kein überdruck herrscht, äst für die Abdichtung der durch diesen Raum führenden Querwelle an ihren Austrittsstellen .aus diesem Raum eine besondere Vorrichtung erforderlich, damit durch den Überdruck von außen keine Flüssigkeit hineingedrückt werden kann. Zu diesem Zwecke sind die Enden der Querwelle an ihren Austrittsstellen aus dem abgedichteten Raum von aus Günuni oder einem anderen dehnbaren Material hergestellten Manschetten umgeben, welche Manschetten die Welle umfassende hülsenförmige Ansätze haben, durch welche infolge des darauf wirkenden überdruckes eine entsprechend sichere automatische Abdichtung erzielt wird.Sealing of the cross shaft in feed pumps, especially with two parallel cylinders arranged to one another o Addendum to patent 4715o9 In the case of the patent 471 509 in your pressure chamber of feed pumps. protected sealed room in which there is no overpressure, ast for the sealing of the leading through this space Cross shaft at its exit points. From this room a special device required so that no liquid is pressed in from the outside due to the overpressure can be. For this purpose the ends of the cross shaft are at their exit points from the sealed space of from Günuni or another stretchable material Manufactured cuffs surrounded, which cuffs encompassing the shaft sleeve-shaped Approaches through which, due to the overpressure acting on it, a corresponding secure automatic sealing is achieved.

In der Zeichnung zeigt Abb. i eine Vorderansicht und Abb. 2 eine Seitenansicht der Förderpumpe im Schnitt, Abb. 3 einen Querschnitt und Abb. q. eine Vorderansicht der Abdichtung in natürlicher Größe.In the drawing, Fig. 1 shows a front view and Fig. 2 shows a side view the feed pump in section, Fig. 3 a cross section and Fig. q. a front view of the seal in natural size.

Der Druckraum der Förderpumpe ist mita bezeichnet; b zeigt die Antriebswelle vom Elektrometer, d und g die Schnecke und das Schneckenrad in dem abgedichteten Raum h, durch welche die Querwelle f angetrieben wird. Die Welle f treibt mittels Exzenters ,i und Pleuelstangen h die hoch. und nieder gehenden Kolben der Pumpen L. Die Querwelle f ist an jeder ihrer beiden Austrittsstellen aus dem abgedichteten Raum h von einer aus Gummi oder einem anderen dehnbaren Material hergestellten Manschette m umgeben, die auf irgendeine Art, beispiehweise an einer in die Raumwand h geschraubten Lagerscheibe n mittels vorgeschraubten Scheibenringes o befestigt ist. Die Manschette m hat einen die Querwelle f umfassenden hülsenförmigen Ansatz p, so daß durch den Druck im Druckraum a eine gute automatische Abdichtung mit dem Ansatz p geschaffen ist.The pressure chamber of the feed pump is denoted by a; b shows the drive shaft of the electrometer, d and g the worm and the worm wheel in the sealed space h, through which the cross shaft f is driven. The shaft f drives up by means of the eccentric, i and connecting rods h. and descending pistons of the pumps L. The transverse shaft f is surrounded at each of its two exit points from the sealed space h by a sleeve m made of rubber or another elastic material, which in some way, for example, on a bearing washer screwed into the room wall h n is fastened by means of a pre-screwed washer ring o. The cuff m has a sleeve-shaped extension p that encompasses the transverse shaft f, so that a good automatic seal with the extension p is created by the pressure in the pressure chamber a.
