About the Book

Ein zentrales Anliegen von Pumpenforschern und -entwicklern ist die Bereitstellung energieeffizienter und zuverlässig funktionierender Pumpen - Pumpen also mit hoher wirtschaftlicher Effizienz. Neben der optimierten Auslegung von Pumpen bereits in der Produktentwicklung ist hierbei die Echtzeit-Überwachung der Pumpe im laufenden Betrieb eine entscheidende Voraussetzung für solch einen wirtschaftlich effizienten Betrieb. Die heute in der industriellen Praxis zum Einsatz kommenden Methoden geben jedoch häufig nur unzureichend Aufschluss über den Betriebs-, Belastungs- und Verschleißzustand der Pumpe. In dieser Arbeit werden deshalb drei neue Maßnahmen vorgestellt, die zur Erhöhung der Energieeffizienz und der Verfügbarkeit von Pumpen beitragen. Eine wichtige Größe zur Detektion von Leckagen und zur energieoptimalen Anpassung der Pumpendrehzahl ist der aktuell durch die Pumpe fließende Volumenstrom. Aus Kostengründen wird dieser heute jedoch meist gar nicht erfasst. Deshalb wurde in dieser Arbeit die integrierte Volumenstromerfassung untersucht, welche die Messung desselben mit günstigen, innerhalb der Pumpe angebrachten Drucksensoren ermöglicht. Anhand experimenteller Untersuchungen wurde gezeigt, dass eine Volumenstrombestimmung mit einer Genauigkeit von ca. ± 1 % Messabweichung vom wahren Volumenstromwert - auch für unterschiedliche Reynoldszahlen - möglich ist. Somit ist nun die wissenschaftliche Grundlage für eine kostengünstige, integrierte Volumenstrombestimmung geschaffen. Eine wichtige Belastungsgröße für eine Pumpe ist Kavitation. Die Bestimmung der Kavitationsintensität ist in der industriellen Praxis bisher nicht möglich. In dieser Arbeit wurde deshalb auf die Kavitationsintensität in einer Pumpe über außen am Gehäuse vorliegende Messsignale geschlossen. Zwar ist eine experimentelle Kalibrierung hierbei nur unter realer Kavitationseinwirkung möglich, dennoch kann das am Gehäuse gemessene akustische Kavitationsintensitätskennfeld zur Überwachung des Kavit
About the Author: Nach dem Maschinenbaustudium bearbeitete Valérie Bischof als Wissenschaftliche Mitarbeiterin am Fachgebiet Fluidsystemtechnik der Technischen Universität Darmstadt (Leitung: Prof. Peter Pelz, vormals Fachgebiet Turbomaschinen und Fluidantriebstechnik unter Leitung von Prof. Bernd Stoffel) das von der DFG geförderte Forschungsprojekt "Integrierte mechatronische Fluidfördersysteme". Im Rahmen dieses Forschungsprojektes entstand unter Anleitung von Prof. Stoffel die vorliegende Dissertation "Effizienzerhöhung von Fluidfördersystemen". Neben den Forschungsarbeiten zur Dissertation unterstütze Frau Bischof eine Industriearbeitsgruppe europäischer Pumpenhersteller (Europump) bei der Erstellung eines Vorschlages für eine EU-Norm zur Energieeinsparung in Pumpensystemen. Heute arbeitet Frau Bischof bei einem weltweit führenden Pumpenhersteller an der Erhöhung der Rentabilität von Pumpensystemen.
