(EN) DRY-RUNNING PISTON ROD PACKING AND METHOD FOR OPERATING A DRY-RUNNING PISTON ROD PACKING
(FR) GARNITURE D'ÉTANCHÉITÉ DE TIGE DE PISTON EN MARCHE À SEC ET PROCÉDÉ DE FONCTIONNEMENT D'UNE GARNITURE D'ÉTANCHÉITÉ DE TIGE DE PISTON EN MARCHE À SEC
Abstract:
(DE) Die trockenlaufende Kolbenstangenpackung (10) zum Abdichten einer in einer Längsrichtung (L) beweglich gelagerten Kolbenstange (5) umfasst zumindest einen Kammerring (3), eine Dichtkammer (3a) sowie einen in der Dichtkammer (3a) angeordneten Dichtring (2), wobei die Kolbenstangenpackung (10) eine Hochdruckseite (10a) sowie eine Niederdruckseite (10b) aufweist, wobei eine Abhebevorrichtung (4) derart ausgestaltet und angeordnet ist, dass diese den Dichtring (2) in Längsrichtung (L) anheben und absenken kann.
(EN) The dry-running piston rod packing (10) for sealing a piston rod (5) supported in such a way that the piston rod can be moved in a longitudinal direction (L) comprises at least one chamber ring (3), a sealing chamber (3a), and a sealing ring (2) arranged in the sealing chamber (3a), wherein the piston rod packing (10) has a high-pressure side (10a) and a low-pressure side (10b), wherein a lift-off device (4) is designed and arranged in such a way that the lift-off device can lift and lower the sealing ring (2) in the longitudinal direction (L).
(FR) L'invention concerne une garniture d'étanchéité de tige de piston en marche à sec (10) pour rendre étanche une tige de piston (5) montée mobile dans une direction longitudinale (L), comprenant au moins une bague de chambre (3), une chambre d'étanchéité (3a) ainsi qu'une bague d'étanchéité (2) disposée dans la chambre d'étanchéité (3a), la garniture d'étanchéité de tige de piston (10) comportant une face haute pression (10a) et une face basse pression (10b). Selon l'invention, un dispositif de levage (4) est conçu et disposé de telle sorte qu'il peut faite monter et descendre la bague d'étanchéité (2) dans la direction longitudinale (L).
