Device for dampening intermittent pumps

Pumpen, wie Kolbenpumpen, Membranpumpen, Schlauchpumpen und dergleichen fördern stoßweise, was für viele Förderaufgaben problematisch ist. Zum Dämpfen der Stöße und damit zum Vergleichmäßigen des Volumenstromes sind Vorrichtungen bekannt, bei denen die Druckstöße der Pumpe durch eine federbelastete Membran ausgeglichen werden. Nachteilig ist im wesentlichen die Reinigung und Wartung der bewegten Teile, die solche Vorrichtungen aufweisen.Pumps such as piston pumps, diaphragm pumps, hose pumps and the like deliver in bursts, which is problematic for many conveying tasks. To dampen the shocks and thus even out the volume flow, devices are known in which the pressure surges of the pump are balanced out by a spring-loaded diaphragm. The main disadvantage is the cleaning and maintenance of the moving parts that such devices have.

Es besteht demnach die Aufgabe, eine Vorrichtung zu schaffen, die einfach in ihrem Aufbau ist und insbesondere keine bewegten Teile aufweist.The task is therefore to create a device that is simple in its construction and, in particular, has no moving parts.

Die Aufgabe wird durch eine Vorrichtung gelöst, die dadurch gekennzeichnet ist, daß in einem allseits geschlossenen Behälter, der mit einer Zuleitung und einer Ableitung für das zu fördernde Medium versehen ist, kollabierbare und mit Gas gefüllte Behältnisse angeordnet sind.The object is achieved by a device which is characterized in that collapsible containers filled with gas are arranged in a container which is closed on all sides and is provided with a supply line and a discharge line for the medium to be conveyed.

Der Behälter kann einen Verscnluß aufweisen, über den die Behältnisse zugänglich sind. Der Behälter kann ferner mit einem Druckmesser versehen sein und die kollabier'oaren Behältnisse können aus mit Luft gefüllten Foliensäcken bestehen.The container may have a closure through which the containers are accessible. The container may also be provided with a pressure gauge and the collapsible containers may consist of foil bags filled with air.

Die Vorrichtung, die preiswert hergestellt werden kann, eignet sich unter anderem zum ^treiben von Chromatographiesäulen. Sie vergleichmüGigt Volumenströme von bis zu 50 l/Stunde bei Drücken von bis zu 20 bar.The device, which can be manufactured inexpensively, is suitable for driving chromatography columns, among other things. It equalizes volume flows of up to 50 l/hour at pressures of up to 20 bar.

Im folgenden wird die Vorrichtung anhand von lediglich einen Ausführungeweg darstellenden Zeichnung näher erläutert. Die Figur zeigt die Vorrichtung perspektivisch.The device is explained in more detail below using a drawing that only shows one possible embodiment. The figure shows the device in perspective.

In einem allseits geschlossenen Behälter I. dessen Hohlraum über einen Schraubversohluß 4 zugänglich le*» «eist eine Zuleitung 2 und eine Ableitung 3 für dao sm fördernde Medium auf. Im Innenraum des Behälters 1 sind koLlabierbare und mit Gas gefüllte Behältnisse 5, z.B. mit iiuft gefüllte
Foliensäcke angeordnet. 6 deutet einen Di'uckmesser und 7 eine Dichtscheibe an.In a container I which is closed on all sides and whose cavity is accessible via a screw cap 4, there is a supply line 2 and a discharge line 3 for the medium to be conveyed. In the interior of the container 1 there are collapsible and gas-filled containers 5, e.g.
Foil bags are arranged. 6 indicates a thickness knife and 7 a sealing disk.
