Labyrinth seal sealing intermediate space between stator and rotor of gas or steam turbine has sealing strips arranged in axial direction fixed to stator working with ring-shaped sealing parts for sealing effect

摘要

The labyrinth seal (30) seals space between stator (10) and rotor (12) has several sealing strips (18) arranged in an axial direction behind one another and fixed to the stator, jutting into the intermediate space (11). They seal together with sealing parts (19) arranged in gaps on the rotor side. The sealing elements are designed as ring-shaped recesses in the rotor.
