Abstract

The internal-gear pump comprises a housing contg. a fixed gear ring with internal teeth. An eccentric pinion meshes with the ring whilst it rotates, so that it carries out a precessing movement. The pinion has a central inlet which connects via a radial duct with the suction region between the meshing teeth, whilst another radial duct connects the pressure region with the central outlet. Inlet and outlet ducts are separated by an inclined partition near the centre.

Description

Titel Universelle lilo chdru ck Innenzahnradpumpe".Title Universelle lilo chdru ck internal gear pump ".

Anwendungsgebiet: Diese Pumpe findet Anwendung im extrem hohen Druckbereich.Durch ihre Konstellation ist die Anwendung auch in getrennter Anordnung zum Medienbehälter möglich.Durch ihre geringe Baugröße findet sie auch in räumlich begrenzten Baumaßnahmen Einsatz.Field of application: This pump is used in extremely high pressure ranges Their constellation is that they can also be used in a separate arrangement from the media container Due to its small size, it can also be found in spatially limited construction projects Mission.

Stand der Technik: Bisher vorhandene Innenzahnradpumpen sind Jeweils mit Füllstücken zwischen den sich drehenden Verzahnungen ausgestattet und drängen das Medium durch den Innenzahnring nach außen lnreg.State of the art: So far existing internal gear pumps are respectively equipped with fillers between the rotating teeth and push Inreg. the medium to the outside through the internal toothed ring.

Kritik des Standes der Technik: Durch diesen Verlauf des Mediums innerhalb der Verzahnung besteht nicht die Möglichkeit, die sehr starken Geräusche der Druckpulsation zwischen Zahnkopf und Zahnfuß zu verhindern.Criticism of the state of the art: By this course of the medium within the toothing does not have the possibility of the very strong noises of the pressure pulsation to prevent between tooth tip and tooth base.

Weiterhin werden die teilweise lose liegenden Füllstücke erheblich auf Abrieb beansprucht. Furthermore, the partially loose filler pieces become significant subjected to abrasion.

Aufgabe: Der Erfindung liegt die Aufgabe zugrunde,die Druckpulsation zwischen der Verzahnung zu verhindern und den Geräuschpegel erheblich zu senken.Weiterhin ist es eine Aufgabe,die Lebensdauer zu erhöhen und den Aktit sradius zu erweitern.Task: The invention is based on the task of the pressure pulsation between the gearing and to reduce the noise level considerably it is a task to increase the service life and to expand the radius of activity.

Lögung: Diese Aufgabe wird erfindungsgemäß dadurch gelöst,daß das Medium zwischen der Verzahnung ßolange über den Durchströmkanal entweichen kann, bis die Verzahnung sich auf dem tiefsten Punkt vereinigt hat.Solution: According to the invention, this object is achieved in that the Medium can escape between the toothing via the flow channel, until the toothing has united at the lowest point.

Durch die extreme große Saug bzw. Druckzone ist die FUllgeschwindigkeit sehr gering gehalten und uirkt sich als Vorteil in der Laufruhe aus. The filling speed is due to the extremely large suction or pressure zone kept very low and has an advantage in terms of smoothness.

Weiterhin wird die Saugfähigkeit enorm gesteigert. Furthermore, the absorbency is increased enormously.

weitere Ausgestaltung der Erfindung: siehe Schema Nr. III erzielbare Vorteile: Hoher Dauerbetriebsdruck Hoher Wirkungsgrad Keine Druckpulsation Minimale Geräuschentwicklung Großes Saugvermögen Geringe Baugröße lis Mehrfachpumpe kombinierbar Lange Lebensdauer Beschreigung: Wird Teil 3, welches aus einem Stück,dem zentrisch liegenden Saugrohr und einer exzentrischen Scheibe besteht in Pfeilrichtung gedreht,kämst Teil 2 (lussenzahnring) an der Innenverzahnung von Teil 1 (Innenzahnring) ab.further embodiment of the invention: see scheme no. III achievable Advantages: High continuous operating pressure High efficiency No pressure pulsation Minimal Noise development Large pumping speed. Small size. Multiple pumps can be combined Long service life Description: Part 3, which is made of one piece, the centric lying suction tube and an eccentric disc is rotated in the direction of the arrow, kämst Part 2 (Lussenzahn ring) on the internal toothing from Part 1 (internal tooth ring).

Am Umfang von Teil 2 sind in gleichem Abstand in Richtung Ringwittelpunkt Durchgangsbohrungen angebracht Durch tias Ineinandergreifen der Verzahnung in der Druckzone wird das Medium in den Auslaß bzw. in den Durchströmkanal gepreßt,während gleichzeitig in der Saugzone die Verzahnung wieder öffnet und somit ein Vakuum erzielt,welches den Saugvorgang verursacht und das Medium durch den Einlaß ansaugt. On the circumference of part 2 are equidistant towards the center of the ring Through holes attached by tias meshing of the teeth in the In the pressure zone, the medium is pressed into the outlet or into the flow channel while at the same time the toothing opens again in the suction zone and thus achieves a vacuum, which causes the suction process and sucks the medium through the inlet.
