Description

Es sind Packungen für die Stopfbüchsen von Kolbenstangen und Tauchkolben von Flüssigkeitspumpen bekannt, bei denen ein oder mehrere Liderungsringe oder Stulpe aus einem elastischen Stoff, wie Gummi o. dgl., durch einen diesen umgebenden Druckschlauch gegen die Kolbenstange bzw. den Kolben gepreßt werden. hei diesen Packungen hat der Stulp rechteckigen Querschnitt und legt sich mit der einen Längsseite abdichtend gegen 'die Kolbenstange, während die andere Längsseite von dem Druckschlauch gepreßt wird. Mit den beiden Schmalseiten stützt sich der Stulp gegen feste, senkrecht zur Achse der Büchse liegende Flächen von Stopfbüchsteilen.They are packings for the stuffing boxes of piston rods and plungers known from liquid pumps in which one or more eyelid rings or cuff made of an elastic material such as rubber or the like, through a pressure hose surrounding it be pressed against the piston rod or the piston. he has these packs the faceplate has a rectangular cross-section and is sealed with one long side against 'the piston rod, while the other long side is pressed by the pressure hose will. With the two narrow sides of the faceplate is supported against solid, perpendicular to the Areas of stuffing box parts lying on the axis of the box.

Dieser Bauart haften verschiedene Mängel an. Erstens wird zu große Reibung zwischen Stulp und Kolbenoberfläche erzeugt, weil der Stulp mit seiner ganzen Längsseite gegen diese gepreßt wird. Erfahrungsgemäß genügt jedoch für die Abdichtung eine Breite der Berührungsfläche von wenigen Millimetern. Zweitens wird der Stulp durch die Reibung von der Kolbenstange ständig etwas hin und her bewegt, da ihn keine .kraft in axialer Richtung festhält außer der Reibung an dem elastischen Druckschlauch. Das ist aber schädlich für dis Haltbarkeit des Stulpes und des Schlauches, da die Bewegung dieser Teile in axialer Richtung und gegeneinander Abnutzung erzeugt.This type of construction has various defects. First is being too big Friction between the faceplate and the piston surface is generated because the faceplate with its whole Long side is pressed against this. Experience has shown, however, that this is sufficient for the seal a width of the contact area of a few millimeters. Second is the forend due to the friction of the piston rod constantly moves something back and forth as it no force in the axial direction holds except for the friction on the elastic pressure hose. But this is detrimental to the durability of the cuff and the hose, as the Movement of these parts in the axial direction and wear against each other generated.

Die Erfindung beseitigt diese Mängel dadurch, daß der Liderungsring oder Stulp aus Gummi o. d-1. an seinen beiden Enden durch ortsfeste Ringe aus Metall o. dgl. zwischen diesen und dein Schlauch festgehalten und in der Mitte abdichtend gegen die Kolbenstange bzw. den Kolbenmantel gepreßt wird. Durch die Reibung zwischen den Rändern des Gummistulpes und den festen Ringen wird der Guministulp festgehalten und seine Bewegung in axialer Richtung verhindert. Ferner wird durch das Anliegen der Stulpränder an den festen Ringen bewirkt, daß der Stulp nicht mit der ganzen Breite gegen die Kolbenoberfläche gepreßt wird, sondern sich ausbaucht und nur mit einer schmalen Ringfläche, die nur wenig Reibung erzeugt, gegen die Kolbenoberfläche drückt.The invention overcomes these deficiencies in that the eyelid ring or forend made of rubber or d-1. fixed rings made of metal at both ends or the like held between these and your hose and sealing in the middle is pressed against the piston rod or the piston skirt. Because of the friction between the edges of the rubber cuff and the fixed rings hold the rubber cuff in place and prevents its movement in the axial direction. Furthermore, through the concern the faceplate on the fixed rings means that the faceplate does not go with the whole Width is pressed against the piston surface, but bulges and only with a narrow ring surface that generates little friction against the piston surface presses.

Die Abbildung zeigt ein Beispiel der Erfindung an einem Axialschnitt einer Stopfbüchse. i ist die Kolbenstange bzw. der Tauchkolben der Pumpe. 2 ist die Gehäusewandung, 3 ist die Grundbüchse und q. die Brille der Stopfbüchse. 5 ist der aus einem Streifen von Gummi o. dgl. bestehende ringförmige Liderungsring oder Stulp, der einen T-förmigen Querschnitt hat und durch die Pressung in dem Schlauch 6 aus Gummi o. dgl., dessen Inneres durch die Verschraubung 7 und das Rohr 8 mit einem Druckraum am besten mit dein Druckraum oder Druelcwindkessel der Pumpe in Verbindung steht, abdichtend gegen die Kolbenstange i gedrückt wird. Damit der Stulp 5 nicht mit seiner ganzen Breite gegen die Stange i gepreßt wird, liegen die beiden vorstehenden Ränder des Stulpes 5 hinter zwei festen Ringen 9 und io, die in der Abbildung Teile der Grundbüchse 3 bzw. der Brille q. sind, und die bewirken, daß der Stulp 5 nicht mit seiner ganzen Breite durch die Pressung im Schlauch 6 gegen die Stange i gepreßt wird, sondern sich ausbaucht und nur mit einer schmalen mittleren Ringfläche gegen die Stange i gepreßt wird, so daß der Reibungswiderstand des Stulpes auf ein Mindestmaß gebracht wird. Außerdem wird der Stulp 5 durch die Reibung zwischen seinen vorstehenden Rändern und den Ringen 9 und io in axialer Richtung festgehalten, so daß er an der hin und her gehenden Bewegung der Kolbenstange nicht teilnehmen kann, und dadurch seine Al,-nutzung auf die an der Kolbenstange beschränkt und die des Schlauches 6 ganz beseitigt wird.The figure shows an example of the invention in an axial section a stuffing box. i is the piston rod or the plunger of the pump. 2 is the housing wall, 3 is the base sleeve and q. the glasses of the stuffing box. 5 is the ring-shaped eyelid ring or the like consisting of a strip of rubber or the like Forend, which has a T-shaped cross-section and due to the compression in the hose 6 made of rubber o a pressure chamber, preferably with your pressure chamber or Druelcwindkessel of the pump in Connection is, is pressed sealingly against the piston rod i. So that the faceplate 5 is not pressed against the rod i with its entire width, the two lie protruding edges of the cuff 5 behind two fixed rings 9 and io, which in the Illustration of parts of the base sleeve 3 or the glasses q. are, and that cause the faceplate 5 does not counteract with its entire width due to the pressure in the hose 6 the rod i is pressed, but bulges out and only with a narrow middle Ring surface is pressed against the rod i, so that the frictional resistance of the cuff is brought to a minimum. In addition, the faceplate 5 is due to the friction between its protruding edges and the rings 9 and io held in the axial direction, so that it does not participate in the reciprocating movement of the piston rod can, and thus its Al, use is limited to that on the piston rod and the of the hose 6 is completely eliminated.
