Abstract

Bei einem Verfahren zur Vergleichmäßigung des Förderstroms bei oszillierenden Verdrängerpumpen, deren Antrieb mittels eines Antriebsmotors über eine rotierende Welle erfolgt, wird derart vorgegangen, dass die Erzeugung des Fluidförderstroms in einer Förderleitung (5) mittels wenigstens zweier oszillierender Verdrängerpumpen (1, 2) erfolgt, deren Antriebsmotoren (6, 7) derart gesteuert werden, dass der insgesamt erzeugte Förderstrom in der Förderleitung (5) weitgehend gleichmäßig bzw. konstant ist.
Die zur Durchführung dieses Verfahrens vorgesehene Vorrichtung gemäß der Erfindung zeichnet sich aus durch wenigstens zwei oszillierende Verdrängerpumpen (1, 2), deren Druckleitung (3, 4) zum Überlagern der einzelnen Förderströme an eine gemeinsame Förderleitung (5) angeschlossen ist und die jeweils einen Antriebsmotor (6, 7) aufweisen, die ohne mechanische Kopplung in elektronischer Synchronisation zum Erzielen eines weitgehend gleichmäßigen bzw. konstanten Summenförderstroms betreibbar sind.
