Endface gap sealing of steam turbine packing seal segments and retrofitting thereof |
摘要 |
Spline seals (58) are disposed in circumferentially registering slots (54, 62) of adjacent arcuate sealing segments (26) disposed in grooves of the casing of a steam turbine about a rotor. The spline seals extend in the gap (50) between the endfaces (56) of the segments and minimize or preclude steam leakage past the endfaces. The spline seals may be oriented axially or inclined radially to minimize leakage paths in the radial inclined and axial directions, respectively. The spline seals are disposed in the slots (54, 62) which may be formed as part of original equipment manufacture or may be machined in segments with the spline seals provided as retrofits. <IMAGE> |
