Abstract

Die Wellenabdichtung der Laufradwelle (20) einer Strömungsmaschine umfasst eine laufradseitige Dichtung (41, 42) sowie eine lagerseitige Dichtung (43) zwischen dem Lagergehäuse (30, 31) und der Welle (20, 21), wobei zwischen der laufradseitigen Dichtung und der lagerseitigen Dichtung eine Ölablaufkammer (53) vorgesehen ist, die Ölablaufkammer (53) von einer dritten Dichtung (44) zwischen dem Lagergehäuse (30, 31) und der Welle (20, 22) begrenzt ist, und zwischen der dritten Dichtung (44) und der laufradseitigen Dichtung eine Gasaustrittskammer (55) angeordnet ist, wobei die Konstruktion durch mindestens eine Ölspritzbohrung (61) im Bereich der Ölablaufrinne (52,63) aktiv gekühlt wird, wodurch eine Verkokung der Wellenabdichtung unterbunden werden kann. Die dritte Dichtung (44) trennt erfindungsgemäss das Öl aus der Ölablaufkammer vom Gas aus der Gasaustrittskammer ab.

The shaft seal of the impeller shaft (20) of a turbomachine comprises an impeller-side seal (41, 42) and a bearing-side seal (43) between the bearing housing (30, 31) and the shaft (20, 21), wherein between the impeller-side seal and the bearing side Sealing an oil drain chamber (53) is provided, the oil drain chamber (53) by a third seal (44) between the bearing housing (30, 31) and the shaft (20, 22) is limited, and between the third seal (44) and the Impeller-side seal a gas outlet chamber (55) is arranged, wherein the construction by at least one oil injection hole (61) in the region of the oil drainage channel (52,63) is actively cooled, whereby a coking of the shaft seal can be prevented. According to the invention, the third seal (44) separates the oil from the oil drain chamber from the gas from the gas outlet chamber.
