Description

Die Erfindung bezieht sich auf eine Verbesserung einer Blähkörperdichtung für Kolbenpumpen nach Patent 624 405, bei der der Blähkörper hinter einem elastischen Kolbenring angeordnet ist, der die Abdichtung" des Kolbens im Zylinder bewirkt.The invention relates to an improvement in an inflatable body seal for piston pumps according to patent 624 405, in which the inflatable body is arranged behind an elastic piston ring which forms the seal "des Piston in the cylinder causes.

In der Praxis hat sich gezeigt, daß, ohne die Pumpe auseinanderzunehmen, nicht einwandfrei festgestellt werden konnte, wann der 'elastische Ring abgenützt war. Es konnte daher vorkommen, daß der mittels Druckluft oder Druckflüssigkeit aufgeblähte Schlauch beschädigt wurde und daß dann das Druckmittel in den Zylinder gelangte.In practice it has been shown that without dismantling the pump, it is not perfect it was possible to determine when the 'elastic ring was worn out. It could therefore it may happen that the hose inflated by means of compressed air or hydraulic fluid was damaged and that the pressure medium then got into the cylinder.

!5 Nach der Zusatzerfindung wird dies dadurch vermieden, daß in dem elastischen Ring ein Metallgewebe und in der Zylinderlauffläche Kontakte einer elektrischen Alarmvorrichtung vorgesehen sind, so daß das Metallgewebe bei abgenütztem Ring die Kontakte schließt. Die Signalvorrichtung spricht an und macht das Bedienungspersonal aufmerksam, daß der Dichtungsring abgenützt ist und erneuert werden muß.! 5 According to the additional invention, this becomes avoided a metal mesh in the elastic ring and in the cylinder running surface Contacts of an electrical alarm device are provided, so that the metal mesh when the ring is worn out the contacts closes. The signaling device responds and alerts the operating personnel, that the sealing ring is worn out and needs to be replaced.

Auf der Zeichnung ist die Erfindung veranschaulicht, und zwar in Fig. 1 im Längsschnitt, in Fig. 2 im Querschnitt und in Fig. 3 in einer besonderen Stellung des Kolbens. Der in dem Zylinder 1 laufende Kolben 2 besitzt zur Abdichtung an der Zylinderwand einen elastischen Ring 3, in dem der Gummischlauch 4 eingebettet ist. Der Ring 3 ist mit einer Einlage 5 aus einem Metallgewebe versehen, welches ebenfalls elastisch ist. Dieses Metallgewebe liegt dicht über der inneren Oberfläche des Ringes 3. Wenn sich der Ring 3 auf seinem äußeren auf der Zylinderwand gleitenden Umfang abnützt, so wird der Ring, da er durch das Druckmittel in dem Schlauch 4 immer wieder aufgebläht wird, auch in abgenütztem Zustand gut abdichten. Die Abnützung kann so lange vor sich gehen, bis das Metallgewebe auf der Zylinderlauffläche schleift. Der Zylinder 1 hat an einem Ende zwei Kontakte 6 und 7, die mit einer elektrischen Signalvorrichtung in Verbindung stehen. Sobald das Metallgewebe die beiden Kontaktflächen berührt, spricht die Signalvorrichtung 8 an.In the drawing, the invention is illustrated, specifically in Fig. 1 in longitudinal section, in Fig. 2 in cross section and in Fig. 3 in a particular position of the piston. The piston 2 running in the cylinder 1 has an elastic ring 3 for sealing on the cylinder wall, in which the rubber hose 4 is embedded. The ring 3 is provided with an insert 5 made of a metal fabric, which is also elastic. This metal mesh lies just above the inner one Surface of the ring 3. When the ring 3 is on its outer on the cylinder wall sliding circumference wears, the ring, since it is inflated again and again by the pressure medium in the hose 4, Seal well even when worn. The wear and tear can go on for so long until the metal mesh rubs on the cylinder surface. The cylinder 1 has on one End of two contacts 6 and 7 that connect to an electrical signal device stand. As soon as the metal mesh touches the two contact surfaces, the signal device speaks 8 at.
