Anti-rotation lug and splitline jumper
View Patent ↗The present invention relates to a system and method for joining adjacent sections of a compressor diaphragm. A splitline jumper is positioned within a recessed portion of a seal ring segment of the adjacent compressor diaphragms. The splitline jumper is sized and oriented so as to prevent axial movement of the compressor diaphragms relative to each other and also to prevent rotational movement of the seal ring relative to the diaphragm.
1. A compressor diaphragm comprising:
a seal ring segment having a forward face, an aft face, first and second opposing side faces, a top face and opposing bottom face;
a stator component coupled to the seal ring segment comprising a platform and a plurality of airfoils extending from the platform; and,
a splitline jumper positioned within the seal ring segment proximate the top face and extending from a side face of the ring segment towards an adjacent compressor diaphragm;
wherein the seal ring segment further comprises a recessed portion sized to receive the splitline jumper; and
wherein the recessed portion further comprises an opening extending through the bottom face of the seal ring segment.
2. The compressor diaphragm of claim 1 , wherein the seal ring segment further comprises a forward hook and an aft hook.
3. The compressor diaphragm of claim 2 , wherein the forward hook and the aft hook engage corresponding slots in the platform of the stator component.
4. The compressor diaphragm of claim 1 , wherein the platform of the stator component further comprises an opening in a platform side face.
5. The compressor diaphragm of claim 1 , wherein the recessed portion is generally U-shaped.
