Description

Die Erfindung betrifft eine Turbomaschine, insbesondere Verdichter in Topfbauweise gemäß dem Oberbegriff des Patentanspruches 1.The invention relates to a turbomachine, particularly a pot-type compressor, according to the preamble of claim 1.

Zur Einhaltung der Betriebsparameter und zur Sicherstellung der geforderten Laufruhe / Betriebssicherheit sind bei der Konstruktion und dem Bau von Turbomaschinen hohe Toleranzanforderungen einzuhalten. Besonders bei Umbauten ohne die Möglichkeit einer Gehäusenachbearbeitung können vorhandene Fertigungsungenauigkeiten zu größeren Problemen bei der Inbetriebnahme der Maschine führen. Die geschilderte Problematik tritt insbesondere dann auf, wenn das Gehäuse eines Verdichters in der Rohrleitung eingeschweißt ist und das aus Rotor- und Statorteilen bestehende Bündel ausgetauscht werden muß.To comply with the operating parameters and to ensure the required smoothness / operational safety, high tolerance requirements must be met when designing and building turbo machines. Particularly in the case of conversions without the possibility of reworking the housing, existing manufacturing inaccuracies can lead to major problems when starting up the machine. The problem described above occurs in particular when the housing of a compressor is welded into the pipeline and the bundle consisting of rotor and stator parts has to be replaced.

Aufgabe der Erfindung ist es, eine Turbomaschine, insbesondere Verdichter in Topfbauweise anzugeben, bei dem eine Umbaukonstruktion ohne die geschilderten Probleme möglich ist.The object of the invention is to provide a turbomachine, in particular a compressor in a pot design, in which a conversion construction is possible without the problems described.

Diese Aufgabe wird ausgehend vom Oberbegriff in Verbindung mit den kennzeichnenden Merkmalen des Patentanspruches 1 gelöst. Vorteilhafte Ausgestaltungen sind Bestandteil von Unteransprüchen.This object is achieved on the basis of the preamble in conjunction with the characterizing features of patent claim 1. Advantageous configurations are part of subclaims.

Kern der Erfindung ist die Befestigung des Lagerbockes am aus dem Gehäuse herausragenden stirnseitigen Ende des Stators des Bündels. Dabei ist erfindungswesentlich, daß der Lagerbock mit dem Bündel und nicht mit dem Gehäuse verbunden ist. Bei einer üblichen konventionellen Konstruktion wird der Flansch des Lagerbockes direkt an das Gehäuse angeschraubt. Die erfindungsgemäße Anordnung ermöglicht eine exakte Positionierung von Rotorteilen zu Statorteilen außerhalb des Gehäuses. Da die Verluste einer Turbomaschine maßgeblich durch die Größe der Spalte zwischen Rotor- und Statorteil beeinflußt werden, ist die optimale Ausrichtung zwischen Rotor- und Statorteil des Bündels von entscheidender Bedeutung. Nach der Ausrichtung in der Werkstatt kann die genaue Lagezuordnung zwischen Rotor- und Statorteil durch Zylinder- und/oder Kegelstifte fixiert werden, so daß nach Abbau der Lagerböcke das ausgerichtete Bündel in das Gehäuse eingeschoben werden kann. Unabhängig von der Lagepositionierung des Bündels zur Gehäuseachse bleibt die eingestellte und die Verlustleistung bestimmende genaue Lagezuordnung zwischen Rotor- und Statorteil erhalten. Dadurch werden mögliche Einflüsse auf das Betriebsverhalten und die Betriebssicherheit der Maschine durch eventuelle Abweichungen in dem vorhandenen Gehäuse im Passungsbereich Bündel zum Gehäuse und Bündel zum Deckel vermieden.The essence of the invention is the attachment of the bearing block to the end of the stator of the bundle protruding from the housing. It is essential to the invention that the bearing block is connected to the bundle and not to the housing. In the case of a conventional construction, the flange of the bearing block is screwed directly onto the housing. The arrangement according to the invention enables an exact positioning of rotor parts to stator parts outside the housing. Since the losses of a turbomachine are largely determined by the The size of the gap between the rotor and stator part are influenced, the optimal alignment between the rotor and stator part of the bundle is of crucial importance. After alignment in the workshop, the exact position assignment between the rotor and stator part can be fixed by cylindrical and / or tapered pins so that the aligned bundle can be inserted into the housing after the bearing blocks have been removed. Regardless of the position of the bundle in relation to the housing axis, the exact position assignment between the rotor and stator parts that determines the power loss is retained. This avoids possible influences on the operating behavior and operational safety of the machine due to possible deviations in the existing housing in the fit area bundle to housing and bundle to the cover.

Mit der vorgeschlagenen konstruktiven Ausführung hat das vorhandene Gehäuse und der vorhandene Deckel keinen Einfluß auf die Lage des Rotors zu den Statorteilen. Aus diesem Grunde ist es möglich, ohne Gehäuse eine Überprüfung der Einbaulage Rotor zu Statorteil vorzunehmen. Dadurch werden Risiken bei der Montage auf der Baustelle in ein vorhandenes Gehäuse minimiert.With the proposed design, the existing housing and the existing cover have no influence on the position of the rotor relative to the stator parts. For this reason, it is possible to check the installation position of the rotor to the stator part without a housing. This minimizes risks when installing on site in an existing housing.

Je nach den Durchmesserverhältnissen zwischen dem stirnseitigen Statorende und dem dazugehörigen Lagerbock kann es zweckmäßig sein, einen Adapter dazwischenzusetzen. Der Adapter wird in erster Linie vorteilhaft dazu genutzt, um einen Ausgleich zu dem in den meisten Fällen einen kleineren Durchmesser aufweisenden aus dem Gehäuse herausragenden Ende des Stators und dem einen größeren Durchmesser aufweisenden Flansch des Lagerbockes zu schaffen.Depending on the diameter ratio between the end of the stator and the associated bearing block, it may be useful to place an adapter in between. The adapter is primarily used advantageously to compensate for the end of the stator, which in most cases has a smaller diameter and protrudes from the housing, and the flange of the bearing block, which has a larger diameter.

Der Adapter kann auch zur Aufnahme einer Dichtung (beispielsweise Sperrlabyrinth) zwischen Lagerbock und Wellendichtung genutzt werden, die bei gasgeschmierten Dichtungen und Labyrinthdichtungen, sowie bei ölgeschmierten Dichtungen mit getrenntem Ölsystem, d. h. Lageröl und Dichtungsöl sind getrennt, erforderlich ist. Der Anschluß des Sperrgases kann dabei direkt am Adapter erfolgen. Der Adapter kann auch zum Durchführen von Anschlußbohrungen zu Dichtungen oder Kammern im Statorende genutzt werden.The adapter can also be used to hold a seal (for example a locking labyrinth) between the bearing block and the shaft seal, which is used for gas-lubricated seals and labyrinth seals, as well as for oil-lubricated seals with a separate oil system. H. Bearing oil and sealing oil are separate, is required. The sealing gas can be connected directly to the adapter. The adapter can also be used to drill connection holes to seals or chambers in the stator end.
