Abstract

The hydraulically driven pump for the feed of liquids, particle laden liquids, or fluids has a pair of intermeshing, multi-vaned, bevel-toothed rotary pistons driven by hydraulic motors and mounted in the pump casing (10). The two identical rotary pistons are driven independently of one another by two similar hydraulic motors (20,30) which are hydraulically connected in parallel and constantly transmit equal torque to the rotary pistons. The rotary pistons are mounted on the shaft ends (21,31) of the hydraulic motors.

Description

Die Erfindung bezieht sich auf eine hydraulisch angetriebene Pumpe zur Förderung von Flüssigkeiten, von mit Partikeln beladenen Flüssigkeiten oder von Fluiden, aufweisend ein Paar miteinander kämmender mehrflügeliger schräg verzahnter Drehkolben, die ihrerseits vermittels von Hydraulikmotoren angetrieben und in einem Pumpengehäuse mit Einlass und Auslass gelagert sind.The The invention relates to a hydraulically driven pump for advancement of liquids, of particle laden liquids or of fluids comprising a pair of intermeshing multi-leaved ones aslant toothed rotary piston, which in turn by means of hydraulic motors driven and in a pump housing with inlet and outlet are stored.

Derartige Pumpen sind bekannt und werden insbesondere dann eingesetzt, wenn partikelbeladene Flüssigkeiten gepumpt werden müssen. Ein wesentliches Merkmal solcher Pumpen ist die Synchronisation, die unbedingt erforderlich ist, damit die Kolben zueinander geordnet arbeiten können. Konstruktiv schlägt sich dies in einem Gleichlaufgetriebe nieder, was dieses einwandfreie Arbeiten der Drehkolben sicherstellen muss.such Pumps are known and are used in particular when particle-laden liquids need to be pumped. An essential feature of such pumps is the synchronization, which is absolutely necessary for the pistons to be ordered to each other can work. Constructive beats this is reflected in a constant velocity gear, what this flawless Make sure the rotors are working.

Bei der vorliegenden Erfindung geht es darum, eine Pumpe der eingangs genannten Art baulich zu vereinfachen.at The present invention is about a pump of the above structurally simplify this type.

Erreicht wird dies dadurch, dass bei einer hydraulisch angetriebenen Pumpe der eingangs genannten Art die beiden zueinander identischen Drehkolben von zwei gleichen Hydraulikmotoren unabhängig voneinander angetrieben sind und dass die Hydraulikmotoren hydraulisch parallel geschaltet sind und stets gleiche Drehmomente auf die Drehkolben übertragen.Reached This is due to the fact that in a hydraulically driven pump of the type mentioned above, the two mutually identical rotary pistons driven by two identical hydraulic motors independently are and that the hydraulic motors are hydraulically connected in parallel and always transmit the same torques to the rotary pistons.

Eine solche Pumpe kann ohne Gleichlaufgetriebe und Synchronisation eingesetzt werden, und zwar sowohl in Vorwärts- als auch in Rückwärtsbetrieb, ohne dass es dabei zu Störungen kommen kann.A such pump can be used without synchronous gearing and synchronization and in both forward and as well as in reverse operation, without causing any interference can come.

Besonders vorteilhaft ist der Einsatzzweck einer solchen Pumpe i m Zusammenhang mit kommunalen Mehrzweckfahrzeugen, die eine Frontaufnahme mit Hydraulikanschluss aufweisen, an der man eine hydraulische Pumpe befestigen kann. Die Pumpe wird mittels eines Schlauches saugseitig an einen mitgeführten Wassertank und druckseitig an einen hydraulisch steuerbaren Arm angeschlossen. Der Fahrer kann dann z.B. Bäume anfahren und diese gezielt bewässern, ohne dass er von seinem Fahrzeug absteigen muss.Especially advantageous is the purpose of such a pump in connection m with municipal multi-purpose vehicles, which have a front intake with hydraulic connection at which one can attach a hydraulic pump. The pump is sucked by a hose to a water tank and connected on the pressure side to a hydraulically controllable arm. Of the Driver can then, e.g. trees start and irrigate them specifically, without having to get off his vehicle.

Weitere vorteilhafte Merkmale gehen aus den Unteransprüchen hervor.Further advantageous features will become apparent from the dependent claims.

Die Erfindung wird nachstehend anhand der Zeichnung beispielsweise erläutert.The Invention will be explained below with reference to the drawing, for example.

1 zeigt einer Längsschnittansicht durch eine Pumpe gemäß der Erfindung. 1 shows a longitudinal sectional view through a pump according to the invention.

2 zeigt eine Schnittansicht gemäß A–A der 1 2 shows a sectional view according to A-A of 1

In den Figuren ist mit 10 das Gehäuse einer Pumpe bezeichnet, in dem zusammen wirkende Drehkolben 22 und 32 angeordnet sind, um Pumpvorgänge auszuführen. Nicht gezeigt sind der Einlass und der Auslass der Pumpe.In the figures is with 10 designates the housing of a pump, in the cooperating rotary pistons 22 and 32 are arranged to perform pumping operations. Not shown are the inlet and the outlet of the pump.

Das Gehäuse 10 der Pumpe ist mit einer Platte 11 nach außen hin abgeschlossen, wobei durch die Platte hindurch zwei Bohrungen gelegt worden sind, die wiederum der Durchführung von Wellen 21 und 31 dienen.The housing 10 the pump is with a plate 11 completed to the outside, with two holes have been placed through the plate, which in turn the implementation of waves 21 and 31 serve.

In der 1 sind zwei Hydraulikmotoren 20 und 30 gezeigt, und zwar nur schematisch und auch nur zum Teil. In jedem Falle sind diese Hydraulikmotoren 20 und 30 mit Wellenenden 21 und 31 ausgebildet, die von außen her in das Gehäuse 10, 11 der Pumpe hineinragen. Auf diese Wellenenden 21 und 31 sind die beiden Drehkolben 22 und 32 von axial außen zum Antrieb hin aufgeschoben.In the 1 are two hydraulic motors 20 and 30 shown, only schematically and only partially. In any case, these are hydraulic motors 20 and 30 with shaft ends 21 and 31 formed from the outside into the housing 10 . 11 protrude the pump. On these shaft ends 21 and 31 are the two rotary pistons 22 and 32 pushed from the outside to the drive axially.

Die richtige Lage der Drehkolben 22 und 32 auf den Wellenenden 21 und 31 wird durch Hülsen sichergestellt, wobei in 1 lediglich die Hülse 23 für den oberen Drehkolben gezeigt ist. Die Hülse 23 dient nicht nur als Anschlag, sondern ist auch dazu gedacht, als Auflager für Laufbuchsen zu dienen, damit eine Wellenabdichtung 24 möglich ist.The correct position of the rotary pistons 22 and 32 on the shaft ends 21 and 31 is ensured by sleeves, with in 1 only the sleeve 23 for the upper rotary piston is shown. The sleeve 23 not only serves as a stop, but is also intended to serve as a support for liners, thus providing a shaft seal 24 is possible.

Im Zusammenhang mit der vorliegenden Erfindung ist es wesentlich, dass der Achsabstand der beiden Wellen 21 und 31 bzw. der Drehkolben 22 so klein gewählt worden ist, dass nur noch Hydraulikantriebe für den Antrieb der beiden Drehkolben in Frage kommen. Es wird ein gedrungener Aufbau der Pumpe insgesamt ermöglicht, wenn Hydraulikmotoren eingesetzt werden.In connection with the present invention, it is essential that the center distance of the two shafts 21 and 31 or the rotary piston 22 so small has been chosen that only hydraulic drives for driving the two rotary pistons come into question. It is a squat design of the pump allows a total when hydraulic motors are used.

Weiterhin ist für die Erfindung wesentlich, dass die beiden Drehkolben zueinander identisch ausgebildet sind, das gleiche trifft auch für die Hydraulikmotoren zu.Farther is for the invention essential that the two rotary pistons to each other are identical, the same applies to the hydraulic motors to.

Bei der Pumpe gemäß der Erfindung ist es möglich, die beiden Drehkolben direkt auf das Antriebsende der Hydraulikmotoren aufzusetzen, zusätzliche separate Wellen sind nicht erforderlich.at the pump according to the invention Is it possible, the two rotary pistons directly on the drive end of the hydraulic motors to set up extra separate waves are not required.

Auch können die Drehkolben aus Metall oder aus Kunststoff hergestellt werden, sie können eine entsprechende Beschichtung haben, so dass sie auch bei aggressiven Medien eingesetzt werden können.Also can the lobes are made of metal or plastic, you can have an appropriate coating, so they are also aggressive Media can be used.
