Z ahnradpumpeGear pump
Die vorliegende Neuerung bezieht sich auf eine Zahnradpumpe. Derartige Pumpen sind absolut anspruchslos und auch betriebssicher» solange keine Korrosion verursachenden Medien gefördert werden.The present innovation relates to a gear pump. Such pumps are absolutely undemanding and also operationally reliable »as long as no media that cause corrosion are conveyed.
Das Ziel der Neuerung ist deshalb die Schaffung einer Zahnradpumpe zur Förderung hochaggressiver Medien,The aim of the innovation is therefore to create a gear pump for pumping highly aggressive Media,
Das erreicht man neuerungsgemäß durch eine Zahnradpumpe mit einem Gehäuse, einem darin gelagerten, mit dem Antrieb verbundenen Verdränger-Zahnrad und einem zweiten, von dem ersten angetriebenen Zahnrad, bei welchen alle mit dem strömenden Medium in Berührung kommenden Teile beständig gegen hochaggressive Medien sind. Vorzugsweise besteht das Gehäuse aus Spezial-Hartporzellan und hat gegebenenfalls eine Metallarmierung und die Zahnräder sind aus PTFE hergestellt. Es ist jedoch nach Maßgabe des zu fördernden Mediums auch möglich, daß sowohl dasAccording to the latest innovation, this can be achieved using a gear pump with a housing, a displacement gear mounted in it and connected to the drive and a second, driven by the first gear, in which all with the flowing medium parts that come into contact are resistant to highly aggressive media. Preferably that exists Housing made of special hard-paste porcelain and, if necessary, has a metal reinforcement and the gears are made of PTFE. However, depending on the medium to be conveyed, it is also possible that both
Gehäuse als auch die Zahnräder aus einem geeigneten Kunststoff be-stehen«The housing and the gears are made of a suitable plastic "
Neuerungsgemäß braucht das nicht mit dem Antrieb verbundene Zahnrad dann nicht gelagert zu werden, wenn es aus PTFE und das Gehäuse aus Porzellan besteht« Dies ermöglicht eine wesentliche Vereinfachung und Verbilligung der gesamten Pumpe, weil die Lagerbohrungen, die Lagerbuchsen und auch die Lagerzapfen entfallen« Das Zahnrad führt sich dann selbsttätig im Gehäuse«According to the innovation, the gear wheel that is not connected to the drive then does not need to be stored, if it is made of PTFE and the housing is made of porcelain «This enables a significant simplification and cheaper of the entire pump because the bearing bores, the bearing bushes and also the Bearing journals are omitted "The gear then automatically guides itself in the housing"
Eine bevorzugte Ausführungsform der Neuerung ist in der beigefügten Zeichnung dargestellt.A preferred embodiment of the innovation is shown in the accompanying drawing.
Ein Pumpenkörper oder Gehäuse trägt das Bezugszeichen 1 und ist aus Porzellan hergestellt« Das Gehäuse 1 ist durch einen Klemmflansch 2 mit einem Deckel 3 aus Glas verschlossen. Als Widerlager für den Klemmflansch 2 dient eine Rückenplatte 4, Klemmflansch 2 und Rückenplatte 4 werden durch Ankerschrauben 5 gegeneinander verspannt« Durch das Gehäuse 1 und die Rückenplatte 4 führt eine Lagerbohrung für eine Antriebswelle 6«A pump body or housing bears the reference number 1 and is made of porcelain «Das Housing 1 is closed by a clamping flange 2 with a cover 3 made of glass. As an abutment a back plate 4, clamping flange 2 and back plate 4 are used for the clamping flange 2 braced against each other by anchor bolts 5 «through the housing 1 and the back plate 4 leads a bearing bore for a drive shaft 6 «
Für diese Antriebswelle ist selbstverständlich eine Dichtung, zum Beispiel eine Gleitringdichtung, vorgesehen, die jedoch nicht dargestellt ist, da sie nicht zur Neuerung gehört«A seal is of course required for this drive shaft, for example a mechanical seal, provided, but not shown because it is not part of the innovation "
Auf der Antriebswelle 6 ist das antreibende Zahn-On the drive shaft 6 is the driving toothed
rad,aus PTFE bestehend, fliegend gelagert und mit einem Kupplungsstift 8 festgesetzt» Es treibt ein zweites ungelagertes Zahnrad 9, ebenfalls aus PTFE, an.wheel, made of PTFE, cantilevered and with a coupling pin 8 fixed »It drives a second non-bearing gear 9, also made of PTFE, on.
Durch die neuerungsgemäße Werkstoffauswahl ist eine derartige Zahnradpumpe nunmehr auch für hochaggressive Medien einsetzbar und es bedarf auch keiner Lagerung für das zweite Zahnrad mehr»Due to the selection of materials according to the innovation Such a gear pump can now also be used for highly aggressive media and it is also required no more storage for the second gear »
