摘要： A rotary machine includes a rotor, a stationary machine casing extending around the rotor, and a bling assembly extending between the casing and the rotor. The machine also includes at least one rotor tip seal assembly and at least one shaft seal assembly. The seal assemblies have a groove configured to receive at least one seal ring band. A method of assembling a rotary machine is also provided. The method includes fabricating the bling assembly by providing two identical members comprising a mating surface and having a semi-circular profile. The method also includes coupling the two members together at their mating surfaces such that a circular ring is formed and such that the mating surfaces define a horizontal joint. The method further includes machining concentric, circular and annular radially inner and outer and airfoil portions within predetermined radial portions of the bling assembly. The method also includes forming at least one abradable layer over a plurality of seal ring bands and inserting the plurality of seal ring bands into the rotor tip and shaft seal ring grooves.

摘要： A method of forming brush seal segments includes mounting a pair of full form plates having opposite arcuate edges in back-to-back relation and wrapping wire about the form plates in multiple passes to form wire runs at angles, e.g., 35-45° relative to radii of the arcuate edges. Half form plates are assembled to opposite sides of the full form plates adjacent one edge of the subassembly. The wire wrap adjacent the one edge of the full form plates is removed. Welds are applied between each adjacent half and full form plates. The inner edges of the wrapped wire and inner frame members of the full form plates are removed. The assembly is then separated to form a pair of arcuate brush seal segments.
