PATENTAMT.PATENT OFFICE.
Die Erfindung betrifft eine Vorrichtung, welche bei einer als Regler wirkenden Schleuderpumpe den Flüssigkeitsdruck beim Eintritt in das Laufrad stets auf der gleichen Höhe erhalten soll.The invention relates to a device which, in a centrifugal pump acting as a regulator the fluid pressure should always be kept at the same level when entering the impeller.
Die Arbeitsflüssigkeit tritt bei dem auf der Zeichnung dargestellten Ausführungsbeispiel aus der allgemeinen Druckleitung bei α in das Reglergehäuse A ein und gelangt von hierIn the embodiment shown in the drawing, the working fluid enters the regulator housing A from the general pressure line at α and arrives from here
ίο durch die Bohrungen b der von der Maschine T angetriebenen Welle W in das Laufrad L. Durch die Drehung des Laufrades erhält die Flüssigkeit beim Austritt aus dem Laufrade einen bestimmten Enddruck, der vonίο through the bores b of the shaft W driven by the machine T into the impeller L. As a result of the rotation of the impeller, the liquid receives a certain final pressure when it emerges from the impeller, which is of
■15 dem Anfangsdruck der Flüssigkeit und der Umlaufszahl des Laufrades abhängig ist. Um diesen Enddruck nur von der Umdrehungszahl des Laufrades allein abhängig zu machen, wird der Anfangsdruck der Flüssigkeit gemäß der Erfindung dadurch auf gleicher Höhe erhalten, daß der Eintritt in das Laufrad von einem Überlauf B umgeben ist, der stets bis zum Rande c mit Flüssigkeit gefüllt bleibt und das überschüssige öl nach dem Gehäuseinnern und von da durch d nach dem Ablauf abfließen läßt. Durch diese Vorrichtung ist der störende Einfluß der Veränderlichkeit des Anfangsdruckes der Arbeitsflüssigkeit ausgeschaltet, da letzterer stets den gleichen nur durch die Höhe des Umlaufs bedingten Wert beibehält.■ 15 depends on the initial pressure of the liquid and the number of revolutions of the impeller. In order to make this final pressure dependent only on the number of revolutions of the impeller, the initial pressure of the liquid according to the invention is obtained at the same level that the inlet into the impeller is surrounded by an overflow B, which is always filled with liquid up to the edge c remains and the excess oil can flow off to the inside of the housing and from there through d after the drain. This device eliminates the disturbing influence of the variability of the initial pressure of the working fluid, since the latter always maintains the same value determined only by the height of the circulation.
