Abstract
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.
Claims20
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.
A splitline jumper for connecting adjacent seal ring segments and preventing rotation of the seal ring segments comprising an elongated body extending a length, having a first end, and opposing second end, a first portion and a second portion, the first portion having a first height and the second portion having a second height, the second height greater than the first height, the first end having a tapered profile and the second ends having a cylindrical profile.
A method of securing adjacent compressor diaphragms together comprising:
- providing a first and second compressor diaphragm, each of the first and second diaphragms 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;
- and,
- a stator component coupled to the seal ring segment comprising a platform and a plurality of airfoils extending from the platform;
- providing a splitline jumper for joining the first and second diaphragms, the splitline jumper comprising an elongated body extending a length and a width and having a first end, an opposing second end, a first portion, and a second portion, the first portion having a first height and the second portion having a second height, the second height greater than the first height;
- placing the second portion of the splitline jumper in the seal ring segment of the first or second diaphragm;
- and
- placing the first portion of the splitline jumper in the seal ring segment of an adjacent compressor diaphragm;
- wherein the splitline jumper couples the first diaphragm to the second diaphragm such that the compressor diaphragms are connected and restricted from rotating relative to each other.
