Oil discharge pipe for axially=flowing gas turbine

摘要

The pipe (12) carries oil away from the case (10) of one bearing of the turbine rotor (1). The bearing is positioned inside the inner annular wall of the exhaust diffuser section (7). The inner and outer walls of the diffuser are connected to each other by flow guide ribs (8), which are distributed equally around its circumference. The discharge pipe has a direct, moveable and oil-tight connection to the lower part of the bearing case, and is led out of the exhaust casing by a hollow, vertical guide rib in the diffuser. The pipe is connected to a spring support (15).
