Description

Bewegliche Dichtung für Schleudermaschinen oder mit diesen in Verbindung stehende Schleuderpumpen Die Erfindung betrifft eine bewegliche Dichtung für Schleudermaschinen oder mit diesen in Verbindung stehende Schleuderpumpen und insbesondere die Art, bei der ein axial und radial beweglicher Ring unter Federdruck gegen eine ebene Dichtungsfläche anliegt. Das Neue besteht darin, daß dem Ring in radialer Richtung ein so geringes Spiel gegeben ist, daß ein drosselnder Spalt und somit ein insbesondere beim Abheben des Ringes von seiner Dichtungsfläche wirkender zusätzlicher Druck entsteht.Movable seal for centrifugal machines or in connection with them Vertical centrifugal pumps The invention relates to a movable seal for centrifugal machines or centrifugal pumps associated with them and in particular the type in which an axially and radially movable ring under spring pressure against a plane The sealing surface. The new thing is that the ring moves in a radial direction there is so little play that a throttling gap and thus a particular one additional pressure acting when the ring is lifted from its sealing surface arises.

Bei dem in der Zeichnung dargestellten Ausführungsbeispiel ist 6 der .axial und radial bewegliche - Ring, der durch eine Feder S gegen den eingesetzten Ring ; angedrückt wird. Durch einen Stift 17, der in eine radiale Nut 16 des Teils 7 eingreift, ist er gegen Drehung gesichert. Er könnte aber auch durch eine bajon:ettartige Verbindung gegen den umlaufenden Teil, z. B. den Pumpenkörper i, gegen Drehung gesichert sein. Zwischen dem Ring 6 und dem Teil i ist die elastische Dichtung 9 angeordnet.In the embodiment shown in the drawing, 6 is the .axially and radially movable - ring which is inserted by a spring S against the Ring ; is pressed. By a pin 17 that goes into a radial groove 16 of the part 7 engages, it is secured against rotation. But it could also be through a bajon: ett-like Connection against the rotating part, e.g. B. the pump body i, secured against rotation be. The elastic seal 9 is arranged between the ring 6 and the part i.

Der Ring 7 hat außen so geringes radiales Spiel, daß sich ein Drosselspalt io ergibt. Da der Raum (Einlauf der Pumpe, in dem die Feder ä liegt, den höheren Druck hat als der andere Raum (Auslauf ), gegen den abgedichtet wird, wird durch den Drosselspalt i o ein zusätzlicher Druck auf den Ring 6 ausgeübt, der besonders dann zur Wirkung kommt, wenn sich der Ring durch irgendwelchen Umstand von seiner Dichtungsfläche abhebt.The ring 7 has so little radial play on the outside that there is a throttle gap io results. Since the space (inlet of the pump, in which the spring is located, is the higher Pressure than the other space (outlet), against which it is sealed, is through the throttle gap i o an additional pressure exerted on the ring 6, which is particularly then comes into effect when the ring by some circumstance is different from his Sealing surface lifts off.

Einer der beiden Teile 6 und ; kann statt aus verschleißfestem Stahl auch aus Kunstharz gefertigt sein.One of the two parts 6 and; can instead of wear-resistant steel also be made of synthetic resin.
