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. Shell 1 and the hoods 3 by means of a flange connection 9 clamped in a known manner and sealed by the seals 10 and 11. The tubes 12 of the tube bundle are in the tube sheet 6 by means of threaded sockets 13 and packing, z. B. Packing cord 17 sealed in a known manner. On both ends of the tube 12 there are sealing rings on the end face 14 arranged from elastic material.
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 welche 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 bores are attached in the tube sheet 6, into which tube sockets 15 are screwed. 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 Dun-'hmessertoleranzen verwendet werden, da Durchmesserunterschiede wegen der Abdichtung durch die Packungsschnur und die stirnseitige Abdichtung sich auf die s Dichtheit nicht auswirken.For the tube bundle, commercially available tubes with the thin knife tolerances specified in the standards can be used because diameter differences due to the seal by the packing cord and the frontal seal affect 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 lu der stirnseitigen Abdichtung ermöglichte seitliche Verschiebbarkeit kompensiert.Inevitable deviations of the tubes in the two tube sheets 6 and 7 are through the means lu the frontal sealing enabled lateral Compensated for displaceability.
Fi g. 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.Fi g. 3 shows a double tube sheet 5, in which the Tube sheet 18 on the hood side consists of a perforated plate, in the bores of which sealing rings 19 are sunk which press against the end faces of the tubes 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 haubenseitigen Rohrboden mit Gewindebüchsen, 1. both hood-side tube sheets with threaded bushings,
2. ein haubenseitiger Boden mit Gewindebuchsen, der andere haubenseitige Bocfcn mit eingelegten Dichtringen, und2. A hood-side base with threaded bushings, the other hood-side bowls with inlaid ones Sealing rings, and
3. beide haubenseitigen Rohrboden mit eingelegten Dichtringen.3. Both hood-side tube sheets with inserted 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 must be trimmed to the exact length.
