Abstract
Description
Die Erfindung bezieht sich auf eine Drehkolbenpumpe mit einem oder mehreren rotierenden Kolben zur Förderung von im Wesentlichen flüssigen Medien, wobei zumindest bereichsweise am Kolben eine Oberflächenlage als Kolbenspitze aus einem Polymer, insbesondere einem Elastomer, befestigt istThe invention relates to a rotary piston pump with one or more rotating pistons for conveying substantially liquid media, wherein at least partially on the piston a surface layer is fixed as a piston tip of a polymer, in particular an elastomer
Die Erfindung bezieht sich auf Drehkolbenpumpen mit geraden, aber auch ebenso gut gewundenen, Kolbenteilen, die bedingt durch das zu fördernde Medium einem mehr oder weniger starken Verschleiß ausgesetzt werden. Wenn aber die Kolbenspitzen verschleißen, sinkt der Wirkungsgrad der Pumpe und diese wird mehr oder weniger schnell unbrauchbar.The invention relates to rotary lobe pumps with straight, but also equally well wound, piston parts that are exposed due to the medium to be conveyed a more or less severe wear. But if the piston tips wear, the efficiency of the pump decreases and this is more or less quickly unusable.
Es sind nachstellbare Kolbenspitzen vorgeschlagen worden, die je nach Verschleiß über einen verschiebbaren Keil nachgestellt werden können (
Den bekannten Lösungen ist gemeinsam, dass der Aufbau des Drehkolbens relativ kompliziert und der Auswechsel- oder Nachstellvorgang sehr zeitaufwändig istThe known solutions have in common that the structure of the rotary piston is relatively complicated and the replacement or readjustment process is very time consuming
Durch die vorliegende Erfindung sollen die Nachteile bekannter Lösungen vermieden werden und insbesondere soll eine Drehkolbenpumpe der eingangs genannten Art so ausgestaltet werden, dass diese mit geringem Aufwand herstellbar und die Montage der Kolbenspitzen einfach ausführbar ist.By the present invention, the disadvantages of known solutions are to be avoided and in particular a rotary pump of the above mentioned type be designed so that they can be produced with little effort and the assembly of the piston tips easily executable.
Erreicht wird dies bei einer Drehkolbenpumpe der eingangs genannten Art dadurch, dass die Kolbenspitze abnehmbar am Grundkörper des Drehkolbens angebracht ist,This is achieved in a rotary piston pump of the type mentioned in that the piston tip is removably attached to the main body of the rotary piston,
Eine weitere Ausführungsform ist dadurch geprägt, dass in der Kolbenspitze mindestens eine Mutter eingeschlossen ist, die jeweils mit einer Befestigungsschraube zusammenwirkt und dass der Kopf der Befestigungsschraube in einer zur Drehkolbenwelle hin offenen Radialausnehmung des Grundkörpers des Drehkolbens angeordnet und mit seinem Gewindeende mit der Mutter im Gewindeeingriff ist.A further embodiment is characterized in that in the piston tip at least one nut is included, each cooperating with a fastening screw and that the head of the fastening screw arranged in a rotary shaft towards the open radial recess of the main body of the rotary piston and with its threaded end with the nut in threaded engagement is.
Weitere Ausgestaltungen sind:
- dass sich zwischen der Oberfläche des Grundkörpers des Drehkolbens und der Kolbenspitze eine mit ihrer Dicke den Verschleiß der Kolbenspitze ausgleichenden Unterlegscheibe oder-matte befindet,
- dass die Befestigungsschraube, die Mutter und die Unterlegscheibe oder -matte zum Produktraum hin abgedichtet untergebracht sind,
- dass die Mutter und die Unterlegscheibe oder -matte in die Kolbenspitze einvulkanisiert sind.
- that between the surface of the main body of the rotary piston and the piston tip is a with its thickness the wear of the piston tip balancing washer or mat,
- that the fastening screw, the nut and the washer or mat are accommodated sealed to the product space,
- that the nut and the washer or mat are vulcanised into the piston tip.
Der Vorteil der vorliegenden Erfindung ist insbesondere darin zu sehen, dass relativ einfache Bolzen-Mutter-Verbindungen eingesetzt werden, um die Kolbespitze am Grundkörper des Drehkolbens zu befestigen. Die Mutter dieser Verbindung ist im Inneren des Polymers bzw. Elastomers der Kolbenspitze untergebracht, d.h. der Elastomerwerkstoff wird nach einer vorteilhaften Ausführungsform um die Mutter herum vulkanisiert. Dabei wird eine Öffnung radial nach innen gelassen, die eine Schraube aufnehmen kann, die nun ihrerseits wieder von innen über die Bohrung des Drehkolbens in eine Ausnehmung hineingesteckt werden kann. Auf diese Art und Weise kann eine relativ einfache aber wirkungsvolle Verbindung der Kolbenspitze mit dem Grundkörper des Drehkolbens geschaffen werden, wobei die Befestigungsteile für die Kolbenspitze nicht vom aggressiven zu pumpenden Medium im Produktraum erreicht werden können.The advantage of the present invention is particularly seen in the fact that relatively simple bolt-nut connections are used to attach the Kolbespitze on the main body of the rotary piston. The mother of this compound is housed inside the polymer or elastomer of the piston tip, ie the elastomer material is after a beneficial Embodiment vulcanized around the mother. In this case, an opening is left radially inwardly, which can accommodate a screw, which in turn can be inserted from the inside again via the bore of the rotary piston in a recess. In this way, a relatively simple but effective connection of the piston tip with the main body of the rotary piston can be created, wherein the fastening parts for the piston tip can not be reached by the aggressive medium to be pumped in the product space.
Je nach Größe des Verschleißes kann als Ausgleich der Verringerung der Radialerstreckung der Kolbenspitzen eine Scheibe oder eine Matte zwischen dem Grundkörper und der Kolbenspitze eingebracht und die Kolben-Mutter-Verbindung danach wieder angezogen werden.Depending on the size of the wear can be introduced as compensation for the reduction of the radial extent of the piston tips a disc or a mat between the body and the piston tip and the piston-nut connection are then tightened again.

In Figur 1 ist zwischen einer Kolbenspitze 10 und dem Grundkörper eines Drehkolbens eine Scheibe 17 vorgesehen. In Figur 2 ist statt einer Scheibe eine Matte 17 gezeigt. Es ist ersichtlich, dass durch den Einsatz der Teile 17 und nach erneuter Montage der Kolbenspitzen 10 ein Verschleiß ausgeglichen werden kann, und zwar so, dass die äußere Radialerstreckung der Kolbenspitzen 10 sich wieder auf dem Kopfkreis des Drehkolbens befindet und damit für eine einwandfreie Funktion des Drehkolbens sorgen.In Figure 1, a
Die Herstellung und insbesondere die Vulkanisation der Kolbenspitzen 10 mit der sich darin befindlichen Mutter und der radialen Ausnehmung stellt kein Problem dar. Der Nachstellvorgang selbst ist ebenfalls relativ einfach zu bewerkstelligen und unterscheidet sich nicht von dem erstmaligen Montagevorgang.The manufacture and in particular the vulcanization of the
