Description
Die Leistungsregelung bei Rotationsmaschinen bis rauf Nulleistung unterliegt nicht unerheblichen Schwierigkeiten und bedingt komplizierte Konstruktionen.The power control for rotary machines down to zero power is subject to considerable difficulties and complicated constructions.
Durch die Erfindung ist eine Einrichtung geschaffen, bei der bei Erreichung eines bestimmten Druckes :das exzentrisch zur Achsmitte gelagerte Gehäuse bis zur Achsmittelstellung .gedrückt wird, die Leistung, der Kraftbedarf und die, Reibung gleich Null werden und auch bei Dauerbetrieb in dieser Stellung kein Verschleiß d es Gehäuses und der Dichtungselemente auftritt.The invention provides a device in which when achieved of a certain pressure: the housing, which is mounted eccentrically to the center of the axis, up to Axle center position. Is pressed, the power, the power requirement and the, friction become equal to zero and no wear even with continuous operation in this position d the housing and the sealing elements occurs.
Die Verschiebung des Gehäuses kann .durch den von ;der Rotationsmaschine selbst erzeugten Druck erfolgen, zum anderen aber auch durch den, Druck in einem Akkumulator oder beispielsweise den Druck einer von derselben Achse angetriebenen druckerzeugenden Maschine, eines Kompressors oder einer Pumpe.The displacement of the housing can be done by the rotating machine self-generated pressure take place, on the other hand also through the, pressure in one Accumulator or, for example, the pressure of one driven by the same axis pressure generating machine, a compressor or a pump.
In dem als Beispiel angenommenen Falle ist die Rotationsmaschine auf der Welle einer Kreiselpumpe angeordnet. Die Rotationsmaschine wirkt in diesem Falle als Vakuumpumpe und entlüftet die Kreiselpumpe, wodurch sich diese mit Wasser anfüllt. Sobald die Kreiselpumpe mit Wasser gefüllt ist, erzeugt sie einen Drück; dieser Druck wird auf das verschiebbare Gehäuse- übertragen, das dadurch in :die Mittelstellung geschoben wird, so daß die Rotationsmaschine keine Arbeit mehr zu leisten hat.In the case assumed as an example, the rotary machine is on arranged on the shaft of a centrifugal pump. The rotary machine works in this case as a vacuum pump and deaerates the centrifugal pump, which fills it with water. As soon as the centrifugal pump is filled with water, it generates a pressure; this Pressure is transferred to the sliding housing, which is then in: the middle position is pushed so that the rotary machine no longer has to do any work.
in der Zeichnung ist die Erfindung in einer Ausführungsform beispielsweise dargestellt.in the drawing the invention is in one embodiment for example shown.
Fig. i zeigt einen Längsschnitt, , Fig. 2 einen Querschnitt und Fig.3 einen Horizontalschnitt durch die Rotationsmaschine; Fig.4 zeigt :die Anordnung der Rotationsmaschine in Verbindung mit einer-Kreiiselpumpe. i ist die Antriebswelle der Rotationsmaschine und gleichzeitig der Kreiselpumpe. 2 ist eine Zylinderbüchse, welche die Arbeitsschieber 3 trägt. 4 ist das Arbeitsgehäuse der Rotationsmaschine, welches in einem äußeren Führungsgehäuse 5, das an das Lagergehäuse 6 der Kreiselpumpe 7 angeschraubt wird, verschiebbar .gelagert ist. 8 ist eine Membran, welche durch einen Deckel 9 eingeklemmt wird. ao ist eine Spiralfeder, welche das Arbeitsgehäuse der Rotationsmaschine in der Arbeitsendstellung hält. i i ist die Ansaugleitung und 12 die Austrittsöffnung für den Ein- und Austritt des Arbeitsmittels. 13 sind die Abschlußdeckel für :die Zylinderbüchse 2 und die Arbeitsschieber 3. 14 ist die Saugleitung für die Evakuierung der Kreiselpumpe 7. 15 ist eine Rückschlagklappe, die durch den von der Pumpe erzeugten Druck gegen das Eintreten von Flüssigkeit in :die Rotationsmaschine geschlossen wird. 16 ist die Leitung für die Druckflüssigkeit von der Kreiselpumpe zur Membran 8, die auf das Arbeitsgehäuse 4 einwirkt, wodurch letzteres in die Achsmittelstellung gedrückt und das Arbeiten der Rotationsmaschine eingestellt wird. 17 ist der Ölraum des Lagergehäuses. Die Rotationsmaschine kann an das Lagergehäuse angeschraubt werden oder auch ,in das Lagergehäuse zwischen zwei Lagern eingebaut werden. Hierdurch ist gleichzeitig die Möglichkeit gegeben, daß das Öl aus dem Ölraum ii7 in die beweglichen Teile der Rotationsmaschine, gegebenenfalls durch besondere Nuten, eintreten kann.Fig. I shows a longitudinal section, Fig. 2 shows a cross section and Fig.3 a horizontal section through the rotary machine; 4 shows: the arrangement the rotary machine in connection with a rotary pump. i is the drive shaft the rotary machine and at the same time the centrifugal pump. 2 is a cylinder liner, which the working slide 3 carries. 4 is the working case of the rotary machine, which in an outer guide housing 5, which is attached to the bearing housing 6 of the centrifugal pump 7 is screwed on, is displaceable. 8 is a membrane which through a cover 9 is clamped. ao is a spiral spring that forms the working housing the rotary machine holds in the working end position. i i is the suction line and 12 the outlet opening for the inlet and outlet of the working medium. 13 are the end caps for: the cylinder liner 2 and the working slide 3. 14 is the Suction line for evacuating the centrifugal pump 7. 15 is a non-return valve, the pressure generated by the pump against the ingress of liquid in: the rotary machine is closed. 16 is the line for the hydraulic fluid from the centrifugal pump to the membrane 8, which acts on the working housing 4, whereby the latter pressed into the axis center position and the working of the rotary machine is set. 17 is the oil chamber of the bearing housing. The rotary machine can be screwed to the bearing housing or also, in the bearing housing between two bearings can be installed. This also gives the opportunity to that the oil from the oil chamber ii7 into the moving parts of the rotary machine, if necessary can occur through special grooves.
