Description

Doppelseitige radiale -Labyrinthdichtttng für Umwälz-Zentrifugalpumpen Große Schwierigkeiten bot bisher die. Abdichtung an der Welle bei Umwälz=Zentrifugalpnmpen für Kochlauge, da der Kocherdruck 8 bis 1a Atm. beträgt. Bei Anwendung der bekannten Stopfbüchspackungan warnicht zu verhindern, daß dauernd etwas Umwälzflüssigk.eit an der Welle austrät und, abgesehen von der gesundheitsschädlichen. Benachteiligung des Kocherwärters; verlorenging. Auch die bekannten Labyrinthdichtungen in zur Welle konzentrischer oder radialjer Bauart, die mit Sperrdampf beschickt werden, führen nicht zur Behebung des Übelstandes. Reine Flüssigkeitsdichtungen, welche aus einer Scheibe mit radialen Schaufeln bestehen und deren Wasserinhalt im Betrieb eine. rotierenden Ring bilden, sind für den. gananu.-ten Zweck überhaupt nicht brauchbar und werden daher auch nur an Pumpen mit geringem Druck, hauptsächlich aber an Saugpumpen, angewendet.Double-sided radial labyrinth seal for circulating centrifugal pumps So far the has presented great difficulties. Sealing on the shaft with circulation = centrifugal pump for cooking liquor, since the cooker pressure is 8 to 1a atm. amounts to. When using the known Stuffing box packings do not prevent a constant flow of circulating fluid emerges on the shaft and, apart from the unhealthy. Disadvantage the cooker keeper; got lost. Also the well-known labyrinth seals in the shaft concentric or radial design that are charged with sealing steam not to remedy the deficiency. Pure liquid seals that consist of a Disc with radial blades exist and their water content in operation a. rotating ring are for the. gananu.-th purpose not at all useful and are therefore only used on pumps with low pressure, but mainly on suction pumps, applied.

Bei der vorliegenden Erfindung handelt es sich um eine doppelseitige, radiale Labyrinthdichtung für Umwälz-Zentrifugalpumpen, deren rotierende Labyrinthscheibe am Umfange gleichzeitig mit radialen Schaufelrippen versehen ist. Diese Labyrinthdichtung wird mit Sperrdampf beschickt, welcher bis an die Welle am innenseitigen Labyrinth eingeführt wird und gegen eine mit hohem überdruck im Innern des Pumpengehäuses kreisende Umwälzilüssigkeit restlos abdichtet. Die radialen Schaufelrippen erzeugen bei der Rotation aus dem Kondensat des Sperrdampfes einen rotierenden in. welchem der bis an den Umfang durchdringende, bereits entspannte Sperrdampf vollends -niedergeschlagen wird. Das außenseitige Labyrinth dient lediglich als Sicherung für alle Fälle. Durch. diese Erfindung, die in der Kombination einer radialen Labyrinthdichtung mit am Umfange angeordneten radialen Schaufelrippen besteht, ist eine Einrichtung für Umwälz-Zentrifugalpumpen geschaffen, welche den praktischen Anforderungen auf absolute Dichtheit in jeder Weise entspricht.The present invention is a double-sided, radial labyrinth seal for circulating centrifugal pumps, their rotating labyrinth disc is provided on the circumference at the same time with radial blade ribs. This labyrinth seal is fed with sealing steam, which reaches the shaft on the inside labyrinth is introduced and against a high pressure inside the pump housing completely seals the circulating fluid. Create the radial blade ribs during the rotation from the condensate of the sealing steam a rotating in. which the already relaxed sealing steam, which penetrates to the circumference, is completely defeated will. The outside labyrinth serves only as a backup in all cases. By. this invention, which in the combination of a radial labyrinth seal with am Circumferentially arranged radial vane ribs is a device for circulating centrifugal pumps created which meet the practical requirements for absolute tightness in each Way corresponds.
