Abstract
Description
Die vorliegende Erfindung betrifft eine Strahlvorrichtung zum Strahlen eines Teiles einer Turbinenschaufel, die einen Schaufelfuß, eine Schaufelplattform und ein Schaufelblatt aufweist, mit einer Strahlkabine, die eine Einsetzöffnungen aufweist, einer Strahleinrichtung zur Abgabe von beschleunigtem Strahlgut in die Strahlkabine und einer Halterung für die Turbinenschaufel, wobei eine Dichtung vorgesehen ist, welche einen Spalt zwischen der Halterung und dem Schaufelblatt im Bereich der Einsetzöffnung abdichtet und so den Austritt von beim Strahlen entstehendem Staub aus der Strahlkabine verhindert.The present invention relates to a blasting device for blasting a part of a turbine blade having a blade root, a blade platform and an airfoil, with a blast cabin having an insertion opening, a blasting device for discharging accelerated blasting material into the blast cabin, and a support for the turbine blade. wherein a seal is provided which seals a gap between the holder and the airfoil in the region of the insertion opening and thus prevents the escape of the dust emerging from the blasting cabin during blasting.
Eine derartige Strahlvorrichtung ist in der
Ein wesentliches Problem beim Strahlen von Turbinenschaufeln ist, dass der hierbei entstehende Staub aus der Kabine austreten und auf die keramische Beschichtung des Schaufelblatts gelangen kann. Hierdurch wird deren Funktion und Lebensdauer beeinträchtigt.A major problem when blasting turbine blades is that the resulting dust can escape from the cabin and get onto the ceramic coating of the airfoil. This affects their function and life.
Bei der vorbekannten Vorrichtung sind Dichtungen vorgesehen, um den Austritt von Staub aus der Kammer zu verhindern. Die Dichtungen sind am unteren Ende der Halterung befestigt und damit für eine kabinenaußenseitige Abdichtung des Spalts ausgelegt. Allerdings bietet diese Konstruktion keine ausreichende Sicherheit, dass die Kabine insgesamt staubdicht verschlossen ist.In the prior art device seals are provided to prevent the escape of dust from the chamber. The seals are attached to the lower end of the bracket and thus designed for a cabin outside sealing of the gap. However, this construction does not provide sufficient security that the cabin is completely sealed dust-tight.
Es ist daher Aufgabe der vorliegenden Erfindung, eine Strahlvorrichtung zu schaffen, bei der der Austritt von Staub aus der Strahlkabine wirksam unterbunden ist.It is therefore an object of the present invention to provide a jet device in which the escape of dust from the blast cabin is effectively prevented.
Diese Aufgabe wird bei einer Strahlvorrichtung der eingangs genannten Art dadurch gelöst, dass die Dichtung den Spalt von der Kabineninnenseite her abdichtet.This object is achieved with a jet device of the type mentioned above in that the seal seals the gap from the inside of the cabin.
Da die Dichtung erfindungsgemäß auf der Kabineninnenseite angeordnet ist, wird bereits das Eindringen von Staub in den Spalt wirksam unterbunden. Auf diese Weise ist sichergestellt, dass kein Staub aus der Kabine zu dem Schaufelblatt gelangen kann.Since the seal according to the invention is arranged on the inside of the cabin, the penetration of dust into the gap is already effectively prevented. In this way it is ensured that no dust from the cabin can get to the blade.
Gemäß einer ersten Ausführungsform der Erfindung kann die Halterung eine Anlagefläche aufweisen, an der die aus der Strahlkabine weisende Fläche der Schaufelplattform zumindest teilweise anliegt. Hierbei ist vorteilhaft, dass die Turbinenschaufel eine zusätzlich Stabilisierung in der Halterung erfährt.According to a first embodiment of the invention, the holder may have a contact surface against which the surface of the blade platform pointing out of the blasting cubicle rests at least partially. It is advantageous that the turbine blade undergoes additional stabilization in the holder.
Die Halterung kann auch ausgebildet sein, um die Turbinenschaufel vertikal hängend aufzunehmen. In diesem Fall trägt die Schwerkraft zur Stabilisierung der Turbinenschaufel in der Halterung bei.The holder may also be designed to receive the turbine blade suspended vertically. In this case, gravity contributes to the stabilization of the turbine blade in the holder.
Es kann auch ein Aufsatz vorgesehen sein, der auf der Kammerinnenseite die Schaufelplattform und die Dichtung übergreift. Vorteilhafterweise schirmt der Aufsatz die Dichtung gegenüber dem in der Kabine vorhandenen Strahlgut ab. Hierdurch wird insbesondere die Lebensdauer der Dichtung erhöht, da diese beim Strahlprozess nicht mehr abgenutzt wird.It can also be provided an essay, which engages over the blade platform and the seal on the inside of the chamber. Advantageously, the attachment shields the seal against the blasting material present in the cabin. As a result, in particular the life of the seal is increased because it is no longer worn during the blasting process.
Um eine sichere Verbindung zwischen dem Aufsatz und der Halterung zu gewährleisten, können beide Bauteile durch eine Befestigungseinrichtung miteinander verbunden sein. Dafür eignen sich beispielsweise Schrauben oder Spannmittel verschiedener Art. Beim Verspannen der Bauteile wird die dazwischen liegende Dichtung komprimiert und so in den Spalt zwischen der Halterung und der Schaufelplattform hinein gedrückt, wodurch der Grad der Abdichtung weiter erhöht wird.In order to ensure a secure connection between the attachment and the holder, both components can be connected to each other by a fastening device. For example, screws or clamping means of various types are suitable. When clamping the components, the intermediate seal is compressed and thus pressed into the gap between the holder and the blade platform, whereby the degree of sealing is further increased.
Es ist ebenfalls möglich vorzusehen, dass die Dichtung an dem Aufsatz befestigt ist. Hierdurch ist ein schnelles, präzises und gleichzeitiges Anordnen des Aufsatzes und der Dichtung möglich. Außerdem wird ein Verrutschen der Dichtung verhindert. Um den Austausch und die Wartung der Dichtung zu erleichtern, kann sie insbesondere abnehmbar an dem Aufsatz befestigt sein.It is also possible to provide that the seal is attached to the attachment. As a result, a quick, precise and simultaneous arrangement of the essay and the seal is possible. In addition, slipping of the seal is prevented. In order to facilitate the replacement and maintenance of the seal, it may in particular be removably attached to the attachment.
Der zu strahlende Teil der Turbinenschaufel kann zumindest von deren Schaufelfuß und gegebenenfalls von Bereichen der dem Schaufelfuß zugewandten Seite der Schaufelplattform gebildet werden.The part of the turbine blade to be radiated can be formed at least from its blade root and optionally from regions of the blade root facing side of the blade platform.
In diesem Fall kann die Strahlvorrichtung ein Abdeckelement aufweisen, welches an der im hängenden Zustand obenliegenden Unterseite des Schäufelfußes anliegt. Wenn die Turbinenschaufel Kühlluftbohrungen aufweist, befinden sich die zugehörigen Lufteintrittsöffnungen der Kühlluftkanäle in der Unterseite des Schaufelfußes. Da die Kühlluftkanäle häufig mit empfindlichen Beschichtungen versehen sind, ist es notwendig, das Eindringen von Staub während des Strahlprozesses zu verhindern. Gemäß dieser Ausführungsform der Erfindung werden die Lufteintrittsöffnungen von dem Abdeckelement verschlossen.In this case, the blasting device may have a covering element which rests against the underside of the blade base which is overhead when suspended. If the turbine blade has cooling air holes, the associated air inlet openings of the cooling air channels are located in the underside of the blade root. Since the cooling air ducts are often provided with sensitive coatings, it is necessary to prevent the ingress of dust during the blasting process. According to this embodiment of the invention, the air inlet openings are closed by the cover.
Es können Spannelemente vorgesehen sein, die ein Verspannen des Abdeckelements mit dem Aufsatz und/oder der Halterung ermöglichen. Hierdurch wird einerseits das Abdeckelement in seiner räumlichen Lage fixiert und andererseits die Turbinenschaufel in der Halterung eingespannt.It can be provided clamping elements that allow a distortion of the cover with the attachment and / or the holder. As a result, on the one hand the cover is fixed in its spatial position and on the other hand clamped the turbine blade in the holder.
Ein grobporiger Schaumstoff kann als Dichtungsmaterial verwendet werden. Dieses Material ist besonders geeignet, da es einerseits eine hohe Dichtigkeit gewährleistet und andererseits eine ausreichende Widerstandsfähigkeit und damit auch eine lange Lebensdauer besitzt.A coarse-pored foam can be used as the sealing material. This material is particularly suitable because it ensures both a high density and on the other hand has sufficient resistance and thus a long life.
Die Dichtung kann 1 bis 15 mm dick sein. Wenn die Dichtung weniger als 1 mm dick ist, besteht die Gefahr einer unzureichenden Abdichtung, wohingegen Dichtungen mit einer Dicke von mehr als 15 mm anfällig für Verschleiß sind. Es hat sich gezeigt, dass Dicken von 2 bis 10 mm und insbesondere 5 mm geeignet sind, eine hohe Dichtigkeit bei gleichzeitig geringem Verschleiß zu gewährleisten.The seal can be 1 to 15 mm thick. If the seal is less than 1 mm thick, there is a risk of insufficient sealing, whereas seals with a thickness of more than 15 mm are susceptible to wear. It has been found that thicknesses of 2 to 10 mm and in particular 5 mm are suitable for ensuring a high level of tightness with at the same time low wear.
Um die Gefahr des Austritts von Staub aus der Kabine noch weiter zu reduzieren, kann auch eine Absaugvorrichtung vorgesehen sein. Diese entfernt den entstehenden Staub kontinuierlich aus der Kabine.In order to further reduce the risk of the escape of dust from the cabin, a suction device may also be provided. This removes the resulting dust continuously from the cabin.
Die Erfindung wird im Folgenden anhand eines Ausführungsbeispiels unter Bezugnahme auf die angefügte Zeichnung näher erläutert.The invention is explained below with reference to an embodiment with reference to the accompanying drawings.

Die Halterung 7 ist im Inneren der Strahlkabine 6 die Einsetzöffnung 8 einfassend angeordnet, wobei sie die Turbinenschaufel 2 vertikal hängend aufnimmt. Dazu ist an der Halterung 7 eine Anlagefläche 9 ausgebildet, an der die aus der Strahlkabine 6 weisende Fläche der Schaufelplattform 4 bereichsweise anliegt. Hierdurch wird zwischen der Halterung 7 und der Schaufelplattform 4 ein Spalt 10 ausgebildet, der bis zur Einsetzöffnung 8 reicht. Dieser Spalt 10 ist kabineninnenseitig durch eine Dichtung 11, welche aus einem grobporigen Schaumstoff besteht und 1 bis 15 mm dick ist, abgedichtet.In the
Die Strahlvorrichtung 1 weist außerdem einen Aufsatz 12 auf, welcher auf der Kabineninnenseite die Schaufelplattform 4 und die Dichtung 11 übergreift. Vorteilhafterweise wird so die Dichtung 11 vor dem Strahlgut geschützt, was deren Lebensdauer erhöht.The blasting device 1 also has an

Dabei wird Staub gebildet, der jedoch durch das Abdeckelement 13 davon abgehalten wird, in die Lufteintrittsöffnungen der Kühlluftkanäle einzudringen. Weiterhin verhindert die Dichtung 11, dass der Staub in den Spalt 10 eindringt, so dass die Strahlkabine 6 insgesamt staubdicht gegenüber der Umgebung verschlossen ist. Damit ist sichergestellt, dass kein Staub aus der Strahlkabine 6 auf das Schaufelblatt 5 gelangen kann.In order to irradiate the
