Description
Insbesondere bezieht sich die Neuerung auf Kreiselpumpen
Bei diesen Pumpen erweist es sich als nachteilige daß infolge der zähflüssigen Konsistenz des in der Pumpe befindlichen zu frdernden Mediums nach längerem Stillstand der Pumpe die zum Anlaufen der Pumpe erforderliche Leistung außerordentlich hoch ist und daher die Antriebsvorrichtung der Pumpe entsprechend hoch dimensioniert werden muß oder die Pumpe selbst nicht mehr durchzieht.In these pumps, it turns out to be disadvantageous that due to the viscous consistency of the medium to be conveyed in the pump longer standstill of the pump the power required to start the pump is extremely high and therefore the drive device of the pump accordingly must be dimensioned large or the pump itself no longer pulls through.
Diesem Übelstand soll gemäß der Neuerung durch einen sich zwischen
Stopfbüchse zur Abdichtung der : Pumpenwelle
und Gehliusewand erstreckenden
Raum zur wahlweisen asz nahme von Kühlwasser für die Stopfbüchse oder von Heiz-Mitteln,
wie Heißwasser oder Dampf. zur Beheizung der Pumpe abgeholfen werden, Die Kühlung
der Stopfbüchse ist im Betrieb der Pumpe von besonderer Bedeutung, weil dadurch
einer Beschädigung des Dichtmaterials durch das heiße zu fördernde Medium stark
entgegengewirkt wird.
In der Zeichnung ist mit 1 die das Pumpenflügelrad 2 tragende Welle bezeichnete die gegenüber dem Druekgehäuse 3 durch eine Stopfbüchsenanordnung 4 abgedichtet ist.In the drawing, 1 is the shaft carrying the pump impeller 2 denoted the opposite to the pressure housing 3 by a stuffing box arrangement 4 is sealed.
Mit 5 ist die Wandung des Druckgehäuse bezeichnet. die bei 6 in einen
Ringkörper übergeht, welcher an eine Ringscheibe 7 anschließt. Diese Ringscheibe
7 ist mit'einem Ringkörper 8 verschweißt, der einen Teil der Stopfbüchsenanordnung
4 bildet. Auf diesem Ring 8 erhebt sich eine
