Abstract
Es ist Aufgabe der vorliegenden Erfindung, die Pumpgrenze eines Verdichters noch weiter positiv zu beeinflussen, als aus dem Stand der Technik vorbekannt. Diese Aufgabe wird erfindungsgemäß dadurch gelöst, dass zusätzlich zu einer Verringerung des Eintrittsquerschnittes des Verdichterrades die Strömung, welche dem Verdichter über einen Verdichtereinritt zufließt derart gestört wird, dass die Pumpgrenze des Verdichters noch weiter positiv beeinflusst wird.It is an object of the present invention, the pumping limit of a compressor even more positively influence, as previously known from the prior art. This object is achieved in that in addition to a reduction of the inlet cross section of the compressor wheel, the flow which flows to the compressor via a compressor inlet is disturbed such that the surge limit of the compressor is further positively influenced.
Description
Die vorliegende Erfindung betrifft eine Vorrichtung zum Betrieb eines Verdichters mit den Merkmalen der unabhängigen Patentansprüche.The present invention relates to an apparatus for operating a compressor with the features of the independent claims.
Wie allgemein bekannt, ist der Betrieb eines Verdichters in Bereichen kritisch, in denen nur ein geringer Massenstrom gefördert wird, jedoch eine vergleichsweise große Druckdifferenz zwischen Verdichteraustritt und Verdichtereintritt vorliegt, Zur positiven Beeinflussung dieser so genannten Pumpgrenze eines Verdichters ist es beispielsweise aus der
