Abstract:
1. A system for reducing wear on a compressor diaphragm comprising: a generally semi-cylindrical compressor shell segment having an inner peripheral surface, two circumferential ends, an axial upstream end and an axial downstream end, wherein the shell segment includes a slot extending along the inner peripheral surface from one circumferential end to the other circumferential end; a diaphragm including an outer shroud with a plurality of airfoils extending radially inward therefrom, wherein the outer shroud is received within the slot in the compressor shell segment, whereby the diaphragm is mounted to the compressor shell segment; and a load applying member having a first portion and a second portion, the first and second portions being biased away from each other by a plurality of springs operatively positioned therebetween, wherein the load applying member is operatively positioned between the compressor shell segment and the diaphragm such that the load applying member exerts a force on the outer shroud, wherein one of the first portion and the second portion contacts the outer shroud, whereby relative movement between the outer shroud and the compressor shell segment is minimized.
