Trockengasdichtungen werden in Prozessgas-Kreiselkompressoren eingesetzt. Um zu verhindern, dass das Prozessgas in die Atmosph\u00e4re entweicht, ist eine Wellenabdichtung erforderlich. Trockengasdichtungen k\u00f6nnen verwendet werden, um die erforderliche Wellenabdichtung zu erreichen, und obwohl sie in einer Vielzahl von Konfigurationen erh\u00e4ltlich sind, wird eine Tandemdichtung typischerweise in einem Sperrgas Versorgungssystem verwendet.<\/p>\n

Tandemdichtungen bestehen aus einer Prim\u00e4rdichtung und einer Sekund\u00e4rdichtung. W\u00e4hrend des normalen Betriebs absorbiert die Prim\u00e4rdichtung den gesamten Druckabfall zu einem Entl\u00fcftungssystem und die Sekund\u00e4rdichtung dient als Reserve, falls die Prim\u00e4rdichtung versagen sollte. Trockendichtungen sind im Grunde Gleitringdichtungen, bestehend aus einem Gegenring (rotieren) und einem prim\u00e4ren (feststehenden) Ring. Im Betrieb erzeugen Nuten im Gegenring eine fluiddynamische Kraft, die dazu f\u00fchrt, dass sich der Prim\u00e4rring vom Gegenring l\u00f6st und ein Laufspalt zwischen den beiden Ringen entsteht. In die Dichtung wird ein Sperrgas eingespritzt, das das Arbeitsmedium f\u00fcr den Laufspalt und die Abdichtung zwischen der Atmosph\u00e4re oder dem Fackelsystem und dem kompressorinternen Prozessgas herstellt.<\/p>\n

Das Erhitzen des Hochdruck-Dichtungsgases ist erforderlich, um die Entfernung von Feuchtigkeit zu gew\u00e4hrleisten und Kondensation innerhalb der Dichtung zu verhindern. Erhitzer von SEICO-Heizungen werden typischerweise in dieser Hochdruckanwendung eingesetzt.<\/p>","protected":false},"excerpt":{"rendered":"
