Abstract
Die erfindungsgemäße Vorrichtung schafft mittels einer externen Pumpe einen Überdruck in einem abgedichteten Bereich unter dem schweren drehenden Rotor mit vertikaler Achse, größer als der Druck im Rest des Gases das den Rotors umgibt und zwar dergestalt, daß eine axial nach oben gerichtete Kraft entsteht, die ein Teil des Rotorgewichts annulliert, sodaß das darunter plazierte Lager stark entlastet wird. Dadurch vermindern sich die Lagerverluste sehr stark und die Lebensdauer des Lager erhöht sich deutlich.The device according to the invention creates by means of an external pump an overpressure in a sealed area under the heavy rotating rotor with a vertical axis, greater than the pressure in the rest of the gas surrounding the rotor, in such a way that an axially upwardly directed force arises which causes a Part of the rotor weight is canceled, so that the bearing placed underneath is greatly relieved. This greatly reduces bearing losses and increases the service life of the bearing significantly.
Description
Die Erfindung bezieht sich auf eine Vorrichtung zur Gewichtsentlastung von Lagern für schwere Rotoren, wie diese beispielsweise aus der
Es gibt eine ganze Reihe von Maschinen, die Rotoren haben, die sich um eine vertikale Achse drehen, wie z. B. die Rotoren von Gaszentrifugen oder die Rotoren von Elektrogeneratoren für Wasserkraftwerke. Dabei hat meistens das unten stehende Lager das ganze Gewicht des Rotors zu tragen. In vielen Fällen handelt es sich um erhebliche Gewichte dieser Rotoren, die viele tonen betragen können und zu enormen Verlusten in den Lagern führen; insbesondere das hohe Gewicht und die höhere Drehzahl erhöhen die Lagerverluste. Dies kann so weit gehen, das deswegen eine praktikable Lösung in manchen Fällen, gar nicht möglich ist.There are quite a number of machines that have rotors that rotate about a vertical axis, such as: As the rotors of gas centrifuges or the rotors of electric generators for hydroelectric power plants. Usually, the bearing below has to carry all the weight of the rotor. In many cases, these are significant weights of these rotors, which can be many tons and cause huge losses in the camps; in particular the high weight and the higher speed increase the bearing losses. This can go so far, that is why a workable solution in some cases, not possible.
Die vorliegende Erfindung schafft Abhilfe in solchen Fällen, indem ein Großteil des Rotorgewichts von einer Vorrichtung übernommen wird, so daß die Lagerbelastung nur von einem Bruchteil des normalen Rotorgewichts verursacht wird. Insbesondere für schnell drehende Rotoren von Gaszentrifugen größeren Ausmaßes, wie etwa für die CO2-Separation von den Abgasen der Kraftwerke, ist das vorgeschlagene Verfahren und Vorrichtung von Bedeutung, denn es reduziert die Lagerverluste auf unter 10% des ursprünglichen Wertes und gleichzeitig erhöht die Lebensdauer der Lager extrem.The present invention provides relief in such cases by taking over a majority of the rotor weight from a device, so that the bearing load is caused only by a fraction of the normal rotor weight. Especially for high-speed rotors of gas centrifuges, such as for CO2 separation from the exhaust gases of power plants, the proposed method and device of importance, because it reduces the bearing losses to less than 10% of the original value and at the same time increases the life of Bearing extreme.
Ein Ausführungsbeispiel der erfindungsgemäßen Vorrichtung ist in der Zeichnung dargestellt und wird im Folgenden näher erläutert.An embodiment of the device according to the invention is shown in the drawing and will be explained in more detail below.
