Gasturbine und Verfahren zur Montage einer Dichtung in dieser Gasturbine

摘要

The seal support includes a stator seal support having an annular seal backing extending axially away and having an integral retention flange at one end. The retention flange includes a retention groove. An annular seal block is supported radially inwardly of the seal backing for cooperating with rotor seal teeth to define a fluid seal. A control ring is disposed radially outwardly of the seal backing and is supported by it. The control ring has circumferentially spaced apart retention tabs cooperating with the retention flange for axially retaining the control ring on the seal backing. An annular heat shield is fixedly joined at one end to the seal support, and includes circumferentially spaced apart retention tabs cooperating with the retention flange for axially retaining the heat shield to the seal backing, while permitting unrestrained differential radial movement between.
