Abstract

Die Erfindung bezieht sich auf eine zentrale Preßölversorgung für Axiallager von Kreiselpumpen, mit einer von der Kreiselpumpenwelle angetriebenen Zahnradpumpe. Aus dem Bestreben, die bisher notwendige separate Ölversorgungsanlage überflüssig zu machen, ergab sich die der Erfindung zugrundeliegende Aufgabe. Eine in das System der Kreiselpumpe integrierte Preßölversorgung wird erreicht mit Hilfe eines in oder an der zu versorgenden Lagereinheit angeordneten Blasenspeichers, der über eine zuführende Leitung mit der Zahnradpumpe und über eine abführende Leitung mit dem Axiallager verbunden ist.The invention relates to a central press oil supply for axial bearings of centrifugal pumps, with a gear pump driven by the centrifugal pump shaft. The aim on which the invention is based resulted from the endeavor to make the previously necessary separate oil supply system superfluous. A press oil supply integrated into the system of the centrifugal pump is achieved with the help of a bladder accumulator arranged in or on the bearing unit to be supplied, which is connected to the gear pump via a supply line and to the axial bearing via a discharge line.

Description

Die Erfindung betrifft eine zentrale Preßölversorgung für Axiallager von Kreiselpumpen, mit einer von der Kreiselpumpenwelle angetriebenen Zahnradpumpe.The invention relates to a central press oil supply For axial bearings of centrifugal pumps, with a gear pump driven by the centrifugal pump shaft.

Das Problem einer solchen Preßölversorgung, die während des Pumpenla ;fs von .iner externen Ölzuführung unabhängig ist. liegt :n der notwendigen Überbrükkung des Anfahr- und eines evc.mellen Notabfahrbetricbs. Während eines solchen Betriebszustandes steht nämlich nicht der zur Schmierölversorgung des Axiallagers erforderliche Öldruck zur Verfugung, da die Zahnradpumpe diesen erst ab einer bestimmten Drehzahl der Kreiselpumpenwellc zu liefern vermag. Um die aufgrund einer unzureichenden Ölversorgung während der kritischen Bclriebsphasen gegebene Gefährdung des Axiallagers zu vermeiden, sah man bisher eine separate Ölvcrsorgungsanlage vor, die insbesondere bei Kreiselpumpen mit hohem Systemdruck und einem bereits beim Anfahren entsprechend hohen Axialschub eine kritische Flächenpressung mit erhöhtem Verschleiß an den Segmenten verhinderte.The problem of such a press oil supply, which is independent of an external oil supply while the pump is running. lies : n the necessary bridging of the start-up and an eventual emergency shutdown operation. During such an operating state, the oil pressure required for supplying lubricating oil to the axial bearing is not available, since the gear pump is only able to supply this from a certain speed of rotation of the centrifugal pump shaft. In order to avoid the endangerment of the axial bearing due to insufficient oil supply during the critical operating phases, a separate oil supply system was previously provided, which prevented critical surface pressure with increased wear on the segments, especially in centrifugal pumps with high system pressure and a correspondingly high axial thrust when starting up .

Der Umstand, daß eine separate Ölversorgungsanlage einen erheblichen zusätzlichen Aufwand bedeutete, im übrigen einen zusätzlichen Platz, verbindende Rohrleitungen und auch Energie beanspruch e. ließ den Wunsch nach einer Einsparung solcher Ölversoraun.iisanlagen entstehenThe fact that a separate oil supply system A considerable additional effort meant, moreover, an additional space, connecting Pipelines and also energy demand e. left the desire to save on such oil supply systems develop

Der Erfindung liegt die Aufgabe zugrunde, eine Preßölversorgung der eingangs genannten Art zu schaffen, die in das System der Kreiselpumpe integriert ist. also auf separate Teile verzichtet. Diese Aufgabe wird erfindungsgemäß gelöst durch einen in oder an der zu versorgenden Lagereinheit angeordneten Blasenspeicher, der über eine zuführende Leitung mit der Zahnradpumpe und über eine abführende Leitung mit dem Axiallager verbunden ist.The invention is based on the object of providing a press oil supply of the type mentioned at the beginning create that integrated into the system of the centrifugal pump is. so there are no separate parts. This object is achieved according to the invention by one in or on the to be supplied storage unit arranged bladder accumulator, which via a supply line with the Gear pump and is connected to the axial bearing via a discharge line.

Weitere Ausgestaltungen der Erfindung ergeben sich aus den Unteransprüchen.Further refinements of the invention emerge from the subclaims.
