Abstract

Bei einer Förderpumpe, insbesondere Mikroförderpumpe für hochviskose Medien, zur Förderung von Medien in einer Förderrichtung (R) mit einem Medieneinlaß (1) und einem Medienauslaß (2), mit zumindest zwei ausbildbaren Kammern (3,4,5,), die in Förderrichtung (R) im wesentlichen hintereinander angeordnet und miteinander verbindbar sind, wird der bezogen auf die Förderrichtung (R) ersten Kammer (3) das zu fördernde Medium über den Medieneinlaß (1) zugeführt und die bezogen auf die Förderrichtung (R) letzte Kammer (5) steht mit dem Medienauslaß in Verbindung. Dabei weisen die Kammern (3,4,5) variable Volumen auf, die über Volumeneinstelleinrichtungen (15,16,17) eingestellt werden. Die Volumeneinstelleinrichtungen (15,16,17) sind durch elektromagnetische Hubelemente und/oder durch Über- und/oder Unterdruckerzeugungseinrichtungen gebildet. Die Verbindung von jeweils zwei benachbarten Kammern (3,4,5) erfolgt über Überströmkanäle (6,7), und das zu fördernde Medium gelangt über die Überströmkanäle (6,7) in die bezogen auf die Förderrichtung (R) jeweils nächste Kammer, wenn das Volumen von zumindest einer von zwei benachbarten Kammern (3,4,5) verändert wird.

In the case of a feed pump, in particular a microfeed pump for highly viscous media, for delivering media in a conveying direction (R) with a media inlet (1) and a media outlet (2), with at least two chambers (3, 4, 5,) which can be formed and which are in the conveying direction (R) are arranged one behind the other and can be connected to one another, the medium (3) to be conveyed is fed to the first chamber (3) in relation to the conveying direction (R) via the media inlet (1) and the last chamber (5 ) is connected to the media outlet. The chambers (3, 4, 5) have variable volumes, which are set via volume adjustment devices (15, 16, 17). The volume adjustment devices (15, 16, 17) are formed by electromagnetic lifting elements and / or by positive and / or negative pressure generating devices. The connection of two adjacent chambers (3, 4, 5) takes place via overflow channels (6, 7), and the medium to be pumped arrives via the overflow channels (6, 7) in the next chamber in relation to the direction of delivery (R), if the volume of at least one of two adjacent chambers (3,4,5) is changed.
