Abstract

The sliders or vane strips in the pump are pressed against the rotor or housing walls by magnetic forces. The sliders or vane strips are made of a permanent magnet material and the walls of a magnetisable material, or vice versa. The sliders or strips may also be made of synthetic carbon with a permanently magnetisable powder constituent matched to the required contact pressure force. The slider or strip can have a permanent magnet core. USE/ADVANTAGE - Vane cell pump or slider pump avoids wear by producing a contact force which always remains constant.

Description

Die Erfindung betrifft eine Sperrschieber- oder Flügelzellenpumpe, insbesondere zur Förderung mit geringer Drehzahl, nach dem Oberbegriff des Pa­ tentanspruchs 1.The invention relates to a gate valve or Vane pump, especially for promotion with low speed, according to the generic term of Pa claim 1.

Bekannte Pumpe (DE-A1 29 13 110, DE-C2 25 47 467) weisen Schieber- oder Flügelleisten auf, die durch Federn, Fluiddruck oder Fliehkraft gegen Rotor- oder Gehäusewände angedrückt werden.Known pump (DE-A1 29 13 110, DE-C2 25 47 467) have slide or wing strips that pass through Springs, fluid pressure or centrifugal force against rotor or housing walls are pressed.

Die Anordnung von Federn oder Fluidleitungen ist technisch sehr aufwendig, die Ausnutzung der Flieh­ kraft ist nur bei mitdrehenden Flügeln möglich, die sich an äußere Wände abstützen, wobei die dadurch erreichte Anlagekraft mit steigender Drehzahl über­ proportional ansteigt und dadurch Verschleiß auf­ tritt.The arrangement of springs or fluid lines is technically very complex, the use of fleeing force is only possible with rotating wings that lean against outer walls, the thereby achieved plant power with increasing speed above increases proportionally and thereby wear occurs.

Hiervon ausgehend liegt der Erfindung daher die Aufgabe zugrunde, eine gattungsgemäße Pumpe derart zu gestalten, daß bei einfachem Aufbau eine gleich­ bleibende Anlagekraft erreicht wird.Proceeding from this, the invention is therefore the Task based on a generic pump like this to design that with a simple structure the same permanent investment is achieved.

Diese Aufgabe ist durch die im Kennzeichen des Patentanspruchs 1 angegebenen Merkmalen gelöst wor­ den. Vorteilhafte Weiterbildungen sind mit den Unteransprüchen angebenen.This task is characterized by the Features specified claim 1 solved wor the. Advantageous further developments are with the Subclaims specified.

Ein Ausführungsbeispiel der Erfindung ist unter An­ gabe von Alternativausbildungen nachfolgend be­ schrieben.An embodiment of the invention is under An Submission of alternative training below wrote.

Eine erfindungsgemäß ausgeführte Sperrschieberpumpe weist einen drehbaren Rotor mit Nockenbahn auf, der zentrisch in einer Zylinderbohrung angeordnet ist und zwei Förderkammern bildet, von denen jede einen Einlaß und Auslaß aufweist. Die Nocken des Rotors bilden Absperrkanten, die mit der Zylinderbohrungs­ mantelfläche zusammenwirken. Die Einlaß- und Aus­ laßbereiche der beiden Förderkammern sind durch Schieberleisten abgedichtet, die im Gehäuse in Lei­ stenschlitzen geführt sind. Diese Schieberleisten sind aus einem Werkstoff mit dauermagnetischer Ei­ genschaft hergestellt und haften unter magnetischer Kraftwirkung an der Wandung des aus einem magneti­ sierbaren Werkstoff bestehenden Rotors und wandern bei Rotordrehung aus den Schlitzen heraus oder her­ ein. Es ist leicht vorstellbar, daß die Werkstoffe mit dauer- und mit magnetisierbaren Eigenschaften auch ausgetauscht werden können, d. h. die Leiste aus magnetisierbarem und der Rotor aus dauermagne­ tischem Werkstoff bestehen können. Vor­ teilhafterweise ist die Schieber- oder Flügelzel­ lenleiste aus Kunstkohle mit einem dauermagneti­ sierbaren Pulveranteil hergestellt und dauermagne­ tisiert und der Pulveranteil und/oder der Dauerma­ gnetisierungsgrad der erforderlichen Schieber- oder Flügelleistenandrückkraft angepaßt.A blocking slide pump designed according to the invention has a rotatable rotor with cam track, which is arranged centrally in a cylinder bore and forms two production chambers, each one Has inlet and outlet. The cams of the rotor  form barrier edges that match the cylinder bore interact surface area. The inlet and out Passage areas of the two delivery chambers are through Sealed slide strips, which in the housing in Lei slot slots are guided. These slide bars are made of a material with a permanent magnetic egg manufactured and adhere under magnetic Force effect on the wall of a magneti material of the existing rotor and migrate when rotating the rotor out of the slots or not a. It is easy to imagine that the materials with permanent and magnetizable properties can also be exchanged, d. H. the bar made of magnetizable and the rotor made of permanent magnet table material can exist. Before geous is the slider or wing tent Plastic molding with a permanent magnet adjustable powder content and permanent magne tized and the powder content and / or the duration Degree of gnetization of the required slide or Wing bar pressure adjusted.

Es ist auch möglich, daß die Schieberleisten aus einem gleitfähigen Werkstoff mit dauermagnetischem Kern hergestellt sind.It is also possible that the slide bars a lubricious material with permanent magnetic Core are made.

Eine etwas andere Lösung sieht alternativ vor, daß in die Leistenschlitze Dauermagnete eingesetzt sind, die mit den dauermagnetisierten Schieberlei­ sten sich abstoßend zusammenwirken und dabei die Anlagekraft bewirken. Bei dieser Ausführung kann der Rotor aus antimagnetischem Werkstoff, ebenso wie das Gehäuse hergestellt werden.Alternatively, a slightly different solution provides that Permanent magnets inserted into the slit slots are with the permanently magnetized slider most of them work together in a repulsive way and thereby Effect investment power. This version can the rotor made of antimagnetic material, as well how the case will be made.

Es versteht sich von selbst, daß diese Anordnungen der Schieberleisten auch auf die Anordnung von Flü­ gelleisten für Flügelzellenpumpen übertragen werden kann, ohne aus dem Rahmen der Erfindung zu fallen.It goes without saying that these arrangements the slide bars also on the arrangement of flü strips for vane pumps are transferred can without falling outside the scope of the invention.
