Abstract

Die Erfindung betrifft ein Verfahren zur Stabilisierung der Temperatur bei einer mit Fördergut geschmierten Zahnradpumpe, bestehend aus mindestens einem Gehäuseteil (G) mit mindestens zwei Gleitlagern (L), in denen Wellen (W) Fördermedium geschmiert gelagert sind. Ein Medium wird in einem Temperieraggregat (TA) auf einen vorbestimmten Temperaturwert eingestellt und durchströmt in der Folge einerseits den mindestens einen Gehäuseteil (G) und anderseits die Wellen (W) und/oder die Gleitlager (L) zum Zwecke der Stabilisierung der Temperatur.
