- the multi-part design of the turbine housing facilitates or allows only the assembly of the rotor in the turbine housing.
- the turbine housing upper part and the turbine housing lower part each have parting surfaces, with which they rest against each other. By means of partial joint screws, the turbine housing upper part and the turbine housing lower part are clamped against each other at the part joint surfaces and thus sealed the parting line.

- the parting screw moves closer to the inner contour of the turbine housing segment, which reduces the leverage and effectively prevents the Ambifugenflansches levering can be.
- the tapering of the flange strip on the inner side of the turbine housing segment thus results in a markedly increased sealing effect, which leads to a significant increase in the operating limits (for example, vapor pressure, steam temperature, temperature difference across the nozzle carriers).
- the welded turbine housing segment according to the invention thus makes it possible to achieve an approximately identical sealing effect as in a cast turbine housing segment, with significantly reduced production costs.
- An inventive embodiment of the invention provides that the taper is formed by means of a chamfer on the flange. Such beveling / chamfering can be produced inexpensively by simple means.
- a further embodiment of the invention provides that the taper is formed by a rounding on the flange.

Description
Die Erfindung betrifft ein geschweißtes Turbinengehäusesegment nach dem Oberbegriff des unabhängigen Patentanspruchs 1 sowie ein Turbinengehäuse mit einem solchen geschweißten Turbinengehäusesegment.The invention relates to a welded turbine housing segment according to the preamble of
Turbinengehäuse, beispielsweise Dampfturbinengehäuse sind üblicherweise aus mehreren Turbinengehäusesegmenten ausgebildet. In der Regel wird dabei das Turbinengehäuse aus zwei Turbinengehäusesegmenten, nämlich einem Turbinengehäuseoberteil und einem Turbinengehäuseunterteil ausgebildet. Die mehrteilige Ausbildung des Turbinengehäuses erleichtert bzw. ermöglicht erst die Montage des Läufers im Turbinengehäuse. Das Turbinengehäuseoberteil und das Turbinengehäuseunterteil weisen jeweils Teilfugenflächen auf, mit denen sie aneinander anliegen. Mittels Teilfugenschrauben wird das Turbinengehäuseoberteil und das Turbinengehäuseunterteil an den Teilfugenflächen gegeneinander verspannt und somit die Teilfuge abgedichtet. Die einzelnen Turbinengehäusesegmente können gegossen oder als geschweißte Bauteile hergestellt werden. Wo es technisch möglich ist, werden geschweißte Turbinengehäusesegmente verwendet, da diese wesentlich kostengünstiger herzustellen sind. Bei hohem Innendruck und/oder hohen Temperaturen müssen hohe Anpressdrücke im Bereich der Teilfuge erzielt werden, um Undichtigkeiten im Bereich der Teilfuge sicher zu verhindern. Wegen des einfacheren Werkstoffes und der geringeren Wandstärken, welche signifikant zur Kostensenkung beitragen, sind bei geschweißten Turbinengehäusesegmenten nicht so hohe Anpressdrücke im Bereich der Teilfuge zu realisieren. Hierdurch kann es im Betrieb zu Undichtigkeiten im Bereich der Teilfuge kommen, so dass das Arbeitsfluid, beispielsweise heißer Dampf im Falle einer Dampfturbine, durch die Teilfuge nach außen austreten kann. Der Innendruck dringt dabei in die Teilfuge ein und wirkt öffnend. Um trotz der begrenzten Anpressdrücke eine Teilfugendichtigkeit zu gewähren, wird derzeit versucht, die Rauigkeit der Teilfugenfläche möglichst gering zu halten. Die entsprechende Bearbeitung der Teilfugenflächen ist dadurch jedoch aufwendig und teuer, so dass der Kostenvorteil der geschweißten Turbinengehäusesegmente zum Teil hierdurch wieder aufgebraucht wird.Turbine housings, for example steam turbine housings, are usually formed from a plurality of turbine housing segments. As a rule, the turbine housing is formed from two turbine housing segments, namely a turbine housing upper part and a turbine housing lower part. The multi-part design of the turbine housing facilitates or allows only the assembly of the rotor in the turbine housing. The turbine housing upper part and the turbine housing lower part each have parting surfaces, with which they rest against each other. By means of partial joint screws, the turbine housing upper part and the turbine housing lower part are clamped against each other at the part joint surfaces and thus sealed the parting line. The individual turbine housing segments can be cast or manufactured as welded components. Where technically possible, welded turbine housing segments are used because they are much cheaper to manufacture. At high internal pressure and / or high temperatures, high contact pressures in the area of the parting line must be achieved in order to reliably prevent leaks in the area of the parting line. Because of the simpler material and the smaller wall thicknesses, which contribute significantly to the cost reduction, not so high contact pressures in the area of the parting line are to be realized in welded turbine housing segments. This can lead to leaks in the region of the parting line during operation, so that the working fluid, for example hot steam in the case of a steam turbine, can escape through the parting line to the outside. The internal pressure penetrates into the parting line and has an opening. In spite of the limited contact pressure To grant a Teilfugendichtigkeit, is currently trying to keep the roughness of the joint surface area as low as possible. However, the corresponding processing of the joint surfaces is thereby complicated and expensive, so that the cost advantage of the welded turbine housing segments is partially used up by this.
Ausgehend vom Stand der Technik ist es daher Aufgabe der vorliegenden Erfindung, ein geschweißtes Turbinengehäusesegment auszubilden, welche eine verbesserte Teilfugendichtigkeit gewährleistet. Des Weiteren ist es Aufgabe der vorliegenden Erfindung, ein Turbinengehäuse mit einem solchen geschweißten Turbinengehäusesegment bereitzustellen.Starting from the prior art, it is therefore an object of the present invention to form a welded turbine housing segment, which ensures an improved Teilfugendichtigkeit. Furthermore, it is an object of the present invention to provide a turbine housing with such a welded turbine housing segment.
Die Aufgabe wird hinsichtlich des geschweißten Turbinengehäusesegmentes durch die Merkmale des unabhängigen Patentanspruchs 1 gelöst. Hinsichtlich des Turbinengehäuses wird die Aufgabe durch die Merkmale des unabhängigen Patentanspruchs 4 gelöst.The object is achieved with respect to the welded turbine housing segment by the features of
Weitere Ausgestaltungen der Erfindung, welche einzeln oder in Kombination miteinander einsetzbar sind, sind Gegenstand der Unteransprüche.Further embodiments of the invention, which are used individually or in combination with each other, are the subject of the dependent claims.
Das erfindungsgemäße geschweißte Turbinengehäusesegment, umfassend ein Wandblech und eine mit dem Wandblech verschweißte Flanschleiste, wobei die Flanschleiste eine Teilfugenfläche ausbildet, zeichnet sich dadurch aus, dass die Flanschleiste derart ausgebildet ist, dass sich die Flanschleiste auf der Turbinengehäusesegmentinnenseite in Richtung der Teilfugenfläche verjüngt. Durch die Verjüngung der Flanschleiste wird die Auflagefläche verringert und damit bei gleicher Schraubenkraft die Anpresskraft erhöht und damit eine bessere Dichtwirkung erzielt. Durch die Verjüngung der Flanschleiste an der Turbinengehäusesegmentinnenseite rückt die Teilfugenschraube darüber hinaus näher an die Innenkontur des Turbinengehäusesegmentes, wodurch die Hebelwirkung verringert und das Aufhebeln des Teilfugenflansches wirkungsvoll verhindert werden kann. Insgesamt ergibt sich somit durch die Verjüngung der Flanschleiste auf der Turbinengehäusesegmentinnenseite eine deutlich erhöhte Dichtwirkung, was zu einer deutlichen Erhöhung der Einsatzgrenzen (beispielsweise Dampfdruck, Dampftemperatur, Temperaturdifferenz über die Leitzeugträger) führt. Durch das erfindungsgemäße geschweißte Turbinengehäusesegment lässt sich somit eine annähernd gleiche Dichtwirkung wie bei einem gegossenen Turbinengehäusesegment, bei deutlich verminderten Herstellkosten erzielen.The welded turbine housing segment according to the invention comprising a wall plate and a flange strip welded to the wall plate, the flange strip forming a parting surface, is characterized in that the flange strip is designed such that the flange strip tapers on the inner side of the turbine housing segment towards the parting surface. By the taper of the flange, the bearing surface is reduced and thus increases the contact pressure with the same screw force and thus achieves a better sealing effect. In addition, by tapering the flange strip on the turbine housing segment inner side, the parting screw moves closer to the inner contour of the turbine housing segment, which reduces the leverage and effectively prevents the Teilfugenflansches levering can be. Overall, the tapering of the flange strip on the inner side of the turbine housing segment thus results in a markedly increased sealing effect, which leads to a significant increase in the operating limits (for example, vapor pressure, steam temperature, temperature difference across the nozzle carriers). The welded turbine housing segment according to the invention thus makes it possible to achieve an approximately identical sealing effect as in a cast turbine housing segment, with significantly reduced production costs.
Eine erfindungsgemäße Ausgestaltung der Erfindung sieht vor, dass die Verjüngung mittels einer Abschrägung an der Flanschleiste ausgebildet ist. Eine solche Abschrägung/Anfasung lässt sich mit einfachen Mitteln, kostengünstig herstellen.An inventive embodiment of the invention provides that the taper is formed by means of a chamfer on the flange. Such beveling / chamfering can be produced inexpensively by simple means.
Eine weitere Ausgestaltung der Erfindung sieht vor, dass die Verjüngung mittels einer Abrundung an der Flanschleiste ausgebildet ist. Die Abrundung kann dabei den gleichen Radius wie das Wandblech des Turbinengehäusesegmentes aufweisen oder einen vom Wandblech unterschiedlichen Radius besitzen. Auch eine von der Kreisform abweichende bogenförmige Verjüngung ist denkbar.A further embodiment of the invention provides that the taper is formed by a rounding on the flange. The rounding can have the same radius as the wall plate of the turbine housing segment or have a different radius from the wall plate. A deviating from the circular arcuate taper is conceivable.
Das erfindungsgemäße Turbinengehäuse zeichnet sich dadurch aus, dass das Turbinengehäuse wenigstens zwei Turbinengehäusesegmente nach einem der vorherigen Ansprüche aufweist, wobei die Turbinengehäusesegmente an den Teilfugenflächen aneinander anliegen. Wie bereits ausgeführt, kommt es durch die Verjüngung der jeweiligen Flanschleisten zu einer Verringerung der Auflagefläche der Teilfugen und damit bei gleichem Anpressdruck zu einer deutlich erhöhten Dichtwirkung. Dadurch dass die Teilfugenschrauben durch die erfindungsgemäße Lösung auch näher an die Innenkontur der Turbinengehäusesegmente heranrückt, wird die Hebelwirkung durch den Innendruck im Turbinengehäuse verringert und ein Aufhebeln des Teilfugenflansches wirkungsvoll verhindert. Eine Ausgestaltung des erfindungsgemäßen Turbinengehäuses zeichnet sich dadurch aus, dass das Turbinengehäuse ein Dampfturbinengehäuse mit zwei Turbinengehäusesegmenten ist und die Turbinengehäusesegmente an horizontalen Teilfugen aneinander liegen. Insbesondere bei Dampfturbinen herrscht häufig ein hoher Dampfdruck verbunden mit hohen Dampftemperaturen. Diese führen zu einer Wärmedehnung der Turbinengehäusehälften und damit zu einem Aufhebeln des Teilfugenflansches. Durch die erfindungsgemäßen Turbinengehäusesegmente kann das Aufhebeln im Bereich der Teilfugenflansche wirkungsvoll verhindert werden wodurch ein Einsatz der Dampfturbine mit höheren Dampfparametern ermöglicht wird.The turbine housing according to the invention is characterized in that the turbine housing has at least two turbine housing segments according to one of the preceding claims, wherein the turbine housing segments abut against each other at the parting surfaces. As already stated, the tapering of the respective flange strips leads to a reduction of the contact surface of the parting joints and thus to a significantly increased sealing effect at the same contact pressure. As a result of the fact that the partial joint screws also move closer to the inner contour of the turbine housing segments as a result of the solution according to the invention, the leverage effect is reduced by the internal pressure in the turbine housing and the levering of the partial joint flange is effectively prevented. An embodiment of the turbine housing according to the invention is characterized in that the turbine housing is a steam turbine housing with two turbine housing segments and the turbine housing segments lie against each other at horizontal parting lines. Especially in steam turbines, there is often a high vapor pressure associated with high steam temperatures. These lead to a thermal expansion of the turbine housing halves and thus to a levering of Teilfugenflansches. By means of the turbine housing segments according to the invention, the levering in the area of the parting joint flanges can be effectively prevented, thereby making it possible to use the steam turbine with higher steam parameters.
