Abstract
Description
Die Erfindung betrifft eine Kolbenvakuumpumpenserie mit mehreren Pumpen, die jeweils ein Pumpengehäuse, mindestens eine im Pumpengehäuse enthaltene Kolbenlaufbuchse und einen in der Kolbenlaufbuchse geführten angetriebenen Kolben aufweisen.The The invention relates to a piston vacuum pump series with several pumps, each with a pump housing, at least one in the pump housing contained piston liner and a driven in the piston liner driven Have pistons.
Kolbenvakuumpumpen
dieser Art sind beispielsweise beschrieben in WO 00/63555 und
Eine Pumpenserie umfasst Pumpen mit unterschiedlichen Kolbendurchmessern. Dies liegt daran, dass die einzelnen Pumpen für unterschiedliche Fördermengen ausgelegt sind und auch für unterschiedliche Druckdifferenzen. Der Kolbendurchmesser bestimmt die Größe und das Format der Kolbenlaufbuchse und deren Bauform hat wiederum Einfluss auf die Größe der umgebenden Gehäuseteile. Folglich ist jeder Typ von Kolbenvakuumpumpe einer Pumpenserie eine individuelle Konstruktion aus eigens dafür gefertigten Komponenten. Hierdurch werden sowohl die Konstruktion als auch die Herstellung und insbesondere die Lagerhaltung für eine solche Pumpenserie mit unterschiedlichen Kolbengrößen sehr aufwendig.A Pump series includes pumps with different piston diameters. This is because the individual pumps have different flow rates are designed and also for different pressure differences. The piston diameter determines the size and that The format of the piston liner and its design in turn has an impact to the size of the surrounding Housing parts. consequently Every type of piston vacuum pump in a pump series is an individual one Construction made especially for this manufactured components. This will both the construction as well as the production and in particular the storage for such a pump series with different piston sizes consuming.
Der Erfindung liegt die Aufgabe zugrunde, eine Kolbenvakuumpumpenserie zu schaffen, deren einzelne Pumpengrößen aus weitgehend standardisierten Gleichteilen zusammengesetzt sind.The The invention is based on the object of a piston vacuum pump series to create whose individual pump sizes are largely standardized Same parts are composed.
Die Lösung dieser Aufgabe erfolgt erfindungsgemäß mit den im Anspruch 1 angegebenen Merkmalen. Hiernach haben die Pumpen derselben Serie gleiche Pumpengehäuse und sie unterscheiden sich durch die Kolbengröße und die Wandstärke der Kolbenlaufbuchsen.The solution This object is achieved according to the invention with the features specified in claim 1. According to this, the pumps of the same series have the same pump housings and they differ in the piston size and the wall thickness of the Piston liners.
Eine Pumpenserie ist dadurch charakterisiert, dass sie mindestens zwei Pumpen mit unterschiedlichen Kolbendurchmessern umfasst. Die Pumpen können separat ausgeführt und angeordnet sein, es kann sich jedoch auch um baulich zusammengefasste Pumpen handeln, beispielsweise um Doppelkolbenpumpen oder um zusammengesetzte Doppelkolbenpumpen.A Pump series is characterized in that it has at least two Pumps with different piston diameters included. The pumps can executed separately and be arranged, but it can also be structurally combined Pumps are, for example, double-piston pumps or composite double-piston pumps.
Die Erfindung verringert die Typenvielfalt der für eine Pumpenserie benötigten Bauteile. Diese wird reduziert auf Kolben und Kolbenlaufbuchsen. Die Gehäuse und die wesentlichen anderen Komponenten können als standardisierte Gleichteile ausgebildet sein. Insbesondere kann auch die Elektronik für alle Pumpentypen gleich sein. Darüber hinaus kann das Gehäuse so ausgebildet sein, dass mehrere Pumpengehäuse hintereinandergesetzt werden können.The Invention reduces the variety of types of components required for a pump series. This is reduced to pistons and piston liners. The housing and the essential other components can be standardized parts be trained. In particular, the electronics can also be used for all pump types be equal. About that in addition, the housing be designed so that several pump housings are placed one behind the other can.
Gemäß einer bevorzugten Ausgestaltung der Erfindung ist vorgesehen, dass das Pumpengehäuse einen Doppelkolben enthält, der mit jedem seiner Enden einen Einlassraum begrenzt und dass jede Kolbenhälfte des Doppelkolbens in einer eigenen Kolbenlaufbuchse geführt ist. Die Kolbenlaufbuchsen können von den entgegengesetzten Enden eines zentralen Gehäuseteils her eingesetzt werden. Ihre Montage erfolgt durch bloßes Einschieben, wozu keine Schraubvorgänge durchgeführt werden müssen.According to one preferred embodiment of the invention it is provided that pump housing contains a double piston, which delimits an inlet space with each of its ends and that each piston half of the double piston is guided in its own piston liner. The piston liners can from the opposite ends of a central housing part be used here. They are assembled by simply pushing them in, why no screwing operations carried out Need to become.
Das Pumpengehäuse kann ein zentrales Gehäuseteil mit einer durchgehenden Bohrung aufweisen, das an entgegengesetzten Seiten mit einem Deckel verschlossen ist, wobei die Bohrung von entgegengesetzten Enden her Kolbenlaufbuchsen enthält.The pump housing can be a central housing part have a through hole, the opposite Sides are closed with a lid, the bore of opposite ends forth contains piston liners.
Gemäß einer bevorzugten Ausgestaltung der Erfindung ist bei einer Doppelkolbenpumpe das Gehäuse aus zwei gleichen axial zusammengesetzten Gehäusehälfte gebildet. Hierdurch kann innerhalb einer Doppelpumpe eine zusätzliche Standardisierung der Gehäusebauteile erfolgen.According to one The preferred embodiment of the invention is for a double-piston pump the housing formed from two identical axially assembled housing halves. This can an additional standardization of the inside of a double pump housing components respectively.
Im Folgenden wird unter Bezugnahme auf die einzige Figur der Zeichnung ein bevorzugtes Ausführungsbeispiel der Erfindung näher erläutert.in the The following will refer to the single figure of the drawing a preferred embodiment the invention closer explained.
In der Zeichnung ist ein Längsschnitt durch mehrere baulich miteinander vereinigte Kolbenvakuumpumpen dargestellt.In the drawing is a longitudinal section through several piston vacuum pumps that are structurally integrated with each other shown.
