Description
Mantel 1 und die Hauben 3 mittels einer Flanschverbindung 9 in bekannter Weise eingespannt und durch die Dichtungen 10 und 11 abgedichtet. Die Rohre 12 des Rohrbündels sind in dem Rohrboden 6 mittels Gewindebuchsen 13 und Dichtungspackungen, z. B. Packungsschnur 17 in bekannter Weise abgedichtet. Auf beiden Enden der Röhre 12 sind stirnseitig Dichtringe 14 aus elastischem Werkstoff angeordnet. Jacket 1 and the hoods 3 clamped in a known manner by means of a flange connection 9 and through the seals 10 and 11 sealed. The tubes 12 of the tube bundle are in the tube sheet 6 by means Threaded bushings 13 and packing, e.g. B. packing cord 17 sealed in a known manner. On both ends of the tube 12, sealing rings 14 made of elastic material are arranged on the end face.
Im hier dargestellten Falle besteht die Abdichtung aus auf das Rohrende gesteckten Dichtringen, z. B. Lippenringen 14. In dem Rohrboden 7 sind Gewindedurchgangslöcher in der gleichen Teilung und Anordnung wie die Bohrungen im 'Rohrboden 6 angebracht, in weiche Rohrstutzen 15 eingeschraubt sind. Die Abdichtung der Rohrstutzen 15 in dem Rohrboden 7 erfolgt mittels dauerelastischem Dichtungsmaterial. Die Stirnseite der Rohrstutzen 15 preßt den Dichtring 14 zusammen und erzeugt die erforderliche Dichtkraft. In the case shown here, the seal consists of sealing rings inserted onto the pipe end, e.g. B. Lip rings 14. In the tube sheet 7 there are threaded through holes in the same pitch and arrangement how the holes in the 'tube sheet 6 are screwed into soft pipe sockets 15. The waterproofing the pipe socket 15 in the tube sheet 7 takes place by means of permanently elastic sealing material. the The end face of the pipe socket 15 presses the sealing ring 14 together and generates the required sealing force.
Mit dieser Konstruktion ergeben sich folgende Vorteile:This construction has the following advantages:
Die stirnseitige Abdichtung der Rohre gegen den Rohrboden erzeugt keine radial gerichteten Kräfte auf die Enden und vermeidet somit Biegezugspannungen, die zu Brüchen führen.The frontal sealing of the tubes against the tube sheet does not generate any radially directed forces the ends and thus avoids bending tensile stresses that lead to breaks.
Für das Rohrbündel können handelsübliche Rohre mit den in den Normen festgelegten Durchmessertoleranzen verwendet werden, da Durchmess»erunterschiede wegen der Abdichtung durch die Packungsschnur und die stirnseitige Abdichtung sich auf die s Dichtheit nicht auswirken.Commercially available tubes with the diameter tolerances specified in the standards can be used for the tube bundle can be used because there are differences in diameter because of the seal by the packing cord and the frontal seal on the s tightness does not affect.
Längstoleranzen der Rohre werden durch die Einschraublängen der Rohrstutzen ausgeglichen.Longitudinal tolerances of the pipes are compensated for by the screw-in lengths of the pipe sockets.
Unvermeidliche Abweichungen der Rohre in den beiden Rohrboden 6 und 7 werden durch die mittels ίο der stirnseitigen Abdichtung ermöglichte seitliche Verschiebbarkeit kompensiert.Inevitable deviations of the tubes in the two tube sheets 6 and 7 are through the means ίο the frontal seal enabled lateral displacement compensated.
Fig. 3 zeigt einen Doppelrohrboden 5, bei dem der haubenseitige Rohrboden 18 aus einer Lochplatte besteht, in deren Bohrungen Dichtringe 19 versenkt eingelegt sind, welche gegen die Stirnseiten der Rohre 12 drücken.Fig. 3 shows a double tube sheet 5, in which the hood-side tube sheet 18 consists of a perforated plate, in the bores of which sealing rings 19 are sunk, which against the end faces of the tubes Press 12.
Es ergeben sich folgende Möglichkeiten für den Zusammenbau der Rohrbündelwärmetauscher:The following options are available for assembling the tube bundle heat exchanger:
1. beide haubenscitigcn Rohrboden mit Gewindebüchsen, 1. both hood-like tube sheets with threaded bushings,
2. ein haubenseitiger Boden mit Gewindebuchsen, der andere haubenseitige Boden mit eingelegten Dichtringen, und2. a hood-side base with threaded sockets, the other base on the hood side with inserted sealing rings, and
3. beide haubenseitigen Rohrboden mit eingelcgten Dichtringen.3. Both hood-side tube sheets with inlaid Sealing rings.
Bei der Ausführung nach Fig. 3 müssen die Bündelrohre auf genaue Länge zugerichtet sein.In the embodiment according to FIG. 3, the bundle tubes be trimmed to the exact length.
