Description
Es sind Dichtungsringe bekannt, die als hohler ringförmiger Körper ausgebildet sind, dessen Inneres mit einem Stoff, beispielsweise Graphit, ausgefüllt ist, der als Schmiermittel für den sich in. der Dichtung bewegenden Maschinenteil dient. Die Ringe sind mit radialen Bohrungen versehen, durch welche die Füllmasse austreten kann.Sealing rings are known which are designed as a hollow annular body, the inside of which is filled with a substance, for example graphite, which acts as a lubricant for the machine part moving in the seal. The rings are with provided radial bores through which the filling compound can emerge.
Die vorliegende Erfindung bezweckt eine ίο besondere Ausgestaltung derartiger Ringe für bestimmte Zwecke. Es gibt Wärmekraft- oder Arbeitsmaschinen, deren Wärmeträger nicht Wasserdampf ist, sondern ein anderer dampfförmiger Stoff, der aber bei gewöhnlichen Druck- oder Temperaturverhältnissen fest ist, beispielsweise ein fester Kohlenwasserstoff. Nach der Erfindung sollen die Ringe mit demjenigen Material ausgefüllt sein, das als Wärmeträger zum Betrieb der betreffenden Maschine dient. Hierdurch wird der Vorteil erreicht, daß keine Fremdkörper in den eigentlichen Wärmeträger hineingelangen können,, wie es der Fall wäre, wenn man ein anderes Schmiermittel, beispielsweise Graphit oder Zylinderöl, für die Dichtungsstelle verwenden würde.The present invention aims at a special embodiment of such rings for specific purposes. There are heat engines or machines whose heat transfer medium is not It is water vapor, but another vaporous substance, which, however, occurs in ordinary Pressure or temperature conditions is fixed, for example a solid hydrocarbon. According to the invention, the rings should be filled with the material that is used as Heat transfer medium is used to operate the machine in question. This creates the advantage achieved that no foreign bodies can get into the actual heat transfer medium, as would be the case if you were to use another lubricant, such as graphite or Cylinder oil, would use for the sealing point.
Die Verwendung des Wärmeträgers zu Schmierzwecken kann noch in der Weise ausgestaltet werden, daß man die Dichtungsringe selbst völlig aus dem Stoff des Wärmeträgers herstellt. Derartige Ringe können entweder allein vierwendet werden, wenn nur gegen geringen Druck abgedichtet werden soll, oder man schaltet sie mit mehreren Hochdruckringen als letzte nach der Seite niedrigen Druckes zu hintereinander. Um ein Abschmelzen des ganzen Ringes zu verhüten, kann gegebenenfalls eine besondere Kühlung, beispielsweise durch Wasser oder Luft, etwa durch aufgesetzte Kühlrippen, vorgesehen werden. Infolge der Kühlung werden die durchtretenden Dämpfe des Füllmittels niedergeschlagen, so daß sich der infolge der Reibung abgeschmolzene Stoff gewissermaßen immer wieder selbst ersetzt. Derartige Ringe bieten also neben den obenerwähnten günstigen Eigenschaften noch den Vorteil, daß auch bei mangelnder Aufmerksamkeit des Bedienungspersonals ein Undichtwerden der Maschine kaum zu befürchten ist.The use of the heat transfer medium for lubrication purposes can also be configured in the way be that the sealing rings themselves are completely made of the material of the heat transfer medium manufactures. Such rings can either be turned alone if they are only sealed against low pressure or you switch them with several high-pressure rings as the last to the side low pressure to one another. To prevent the whole ring from melting off, can optionally be a special cooling, for example by water or air, for example by attached cooling fins. As a result of the cooling, the penetrating Vapors of the filler precipitated, so that the substance melted off as a result of the friction to a certain extent Replaced itself again and again. Such rings therefore offer in addition to the above-mentioned favorable Properties still have the advantage that even if the operator does not pay enough attention there is little risk of the machine leaking.
In der Abbildung ist eine Stopfbuchse im Schnitt schematisch dargestellt, bei der Hohlringe und Vollringe hintereinandergeschaltet sind, ι bezeichnet die abzudichtende Welle, 2 den Zylinder, 3 die Stopfbüchse, 4 dieStopf buchsenbrille. Zur Abdichtung gegen den hohen Druck sind Hohlringe 5 und 6 angeordnet, die mit der Masse des Wärmeträgers angefüllt sind. Nach der Seite niedrigen Druckes dagegen sind zwei Ringe 7 und 8 vorgesehen, die aus dem Stoff des Wärmeträgers selbst hergestellt sind. Uta ein Abschmelzen zu verhüten, enthält der Teil der Stopfbüchse, in dem diese beiden Ringe sitzen, Kühlringe 9 und 10, die dauernd von Kühlwasser durchflössen werden. Eine andere Ausführungsmöglichkeit der Kühlung zeigt die Abb. 2, nach der die Kühlringe durch aufgesetzte Kühlrippen aus gut wärmeleitendem Material ersetzt sind.The figure shows a schematic section of a stuffing box with hollow rings and full rings are connected in series, ι denotes the shaft to be sealed, 2 the cylinder, 3 the stuffing box, 4 the stuffing box gland. To seal against the high pressure, hollow rings 5 and 6 are arranged, which are filled with the mass of the heat carrier are. On the other hand, on the low pressure side, there are two rings 7 and 8, which are made from the material of the heat carrier itself. Uta to prevent a meltdown, the part of the stuffing box in which these two rings sit contains cooling rings 9 and 10, which are continuously traversed by cooling water. Another option for cooling is shown in Fig. 2, after which the cooling rings through attached cooling fins made of a material that conducts heat well are replaced.
