Abstract
Description
Die Erfindung betrifft eine Förderpumpe für hydraulische Medien.The The invention relates to a feed pump for hydraulic Media.
Förderpumpen besitzen ein Fördervolumen, welches von der Drehzahl der Förderpumpe und deren Antrieb abhängt. Abhängig vom Systemwiderstand des Verbrauchers beziehungsweise der das geförderte hydraulische Medium verbrauchenden Einrichtungen hängt auch der Systemdruck vom Fördervolumen ab. In der Regel besteht der Wunsch, den Systemdruck auf einem konstanten Niveau oder zumindest innerhalb einer vorgegebenen Bandbreite zu halten.feed pumps have a delivery volume, which from the speed of the feed pump and whose drive depends. Dependent from the system resistance of the consumer or the hydraulic pumped Medium consuming devices also depends on the system pressure of delivery from. As a rule, there is a desire to keep the system pressure at a constant level Level or at least within a given bandwidth hold.
