Abstract:
1. A system for reducing wear on a compressor diaphragm comprising: a substantially semi-cylindrical compressor shell having a radially outer peripheral surface, a radially inner peripheral surface, two circumferential ends, an axial upstream end and an axial downstream end, wherein the shell includes a slot extending along the radially inner peripheral surface from one circumferential end to the other circumferential end, wherein the shell further includes at least one recess located substantially at one of the circumferential ends, the recess opening into the slot in the direction of one of the axial ends of the shell; a diaphragm including an outer shroud with a plurality of airfoils extending radially therefrom, the outer shroud having a forward face and an aft face, wherein the outer shroud is received within the slot in the compressor shell; and a load applying member disposed within the recess, wherein the member exerts an axial force on one of the faces of the outer shroud in the direction of one of the axial ends of the shell.
