PATENTAMT.PATENT OFFICE.
Gegenstand der Erfindung ist eine Vorrichtung zur Graphitierung von beweglichen Maschinenteilen·, insbesondere von Rohrleitungsrohren, die in Stopfbüchsen eingeführt werden. Der Graphit wird auf den zu graphitierenden Maschinenteil unter starkem Druck und auch' unter Erhitzung und Bewegung des Maschinenteiles aufgebracht, so daß der in die Poren des Metalls eindringende Graphit eine festeThe subject of the invention is a device for graphitizing moving machine parts, in particular of pipelines that are inserted into stuffing boxes. The graphite is applied to the machine part to be graphitized under strong pressure and also ' applied with heating and movement of the machine part, so that the in the pores of the metal penetrating graphite a solid
iö Kruste bildet, welche dem Maschinenteil vorzügliche Glätte verleiht und zugleich als Schutz gegen Rosten dient.iö crust forms which the machine part exquisite Gives smoothness and at the same time serves as protection against rusting.
Auf der Zeichnung ist eine Ausführungsform der Vorrichtung im Längsschnitt dargestellt.In the drawing, an embodiment of the device is shown in longitudinal section.
Das Gestell α ist zu einem Ring b ausgebildet, in den der zu graphitierende Maschinenteil genau hineinpaßt. Der Ring b ist mit einer Aussparung versehen, in welche ein mit Graphit getränktes Dichtungsmaterial c (Asbest o. dgl.) mittels eines Flansches d eingepreßt wird, so daß der bewegliche Maschinenteil wie von einer Stopfbüchse umfaßt wird.The frame α is formed into a ring b into which the machine part to be graphitized fits exactly. The ring b is provided with a recess into which a graphite-impregnated sealing material c (asbestos or the like) is pressed by means of a flange d so that the movable machine part is encompassed as by a stuffing box.
Bei dem auf der Zeichnung dargestellten Ausführungsbeispiel ist als beweglicher Maschinenteil ein als Degenrohr für Rohrleitungsstopfbüchsen zu verwendendes Rohr e gewählt. In the embodiment shown in the drawing, a tube e to be used as a sword tube for pipeline glands is selected as the movable machine part.
Das Rohr e wird während der Graphitierung mittels einer geeigneten- (auf der Zeichnung nicht dargestellten) Vorrichtung im Ring 5 hin und her bewegt, so daß der Graphit aus der Dichtung c allmählich in die Poren des Rohres eindringt und eine feste Kruste auf dem Rohr bildet.The tube e is moved back and forth in the ring 5 during the graphitization by means of a suitable device (not shown in the drawing) so that the graphite from the seal c gradually penetrates into the pores of the tube and forms a solid crust on the tube .
Damit das Rohr e während der Graphitierung von außen und von innen her erhitzt werden kann, ist der Ring b hohl ausgebildet und das Rohr e selbst zuerst mit einem nachträglich nach der Linie f-g abzuschneidenden Boden h versehen.So that the tube e can be heated from the outside and from the inside during the graphitization, the ring b is hollow and the tube e itself is first provided with a base h to be cut off after the line fg .
In den Hohlraum i des Ringes b wird nun mittels eines Leitungsrohres k heißer Dampf zugeführt, welcher durch ein Auslaßrohr / wieder abgeführt wird, während man durch das Rohr e mittels geeigneter Schlauchleitungen m und n, o. dgl., heißen Dampf fortwährend hindurchziehen läßt.In the cavity i of the ring b , hot steam is now fed by means of a pipe k , which is discharged again through an outlet pipe, while hot steam is continuously allowed to pass through the pipe e by means of suitable hose lines m and n, or the like.
