Method and machinery with combined particle separation and flow regulation devices

摘要

A method for assembling turbomachinery having combined particle separation device and flow regulating device is provided. The turbomachinery includes a casing (40); a compressor (38) attached to an inside of the casing (40), the compressor (38) having a shaft supported by bearings; and a cooling system mounted inside the casing and configured to cool the bearings of the compressor with a cooling fluid. The cooling system includes a particle separation device (42) configured to separate particles from the cooling fluid, and a flow regulation device (44) that fluidly communicates with the particle separation device (42) without contacting the particle separation device (42). The flow regulation device (44) is disposed adjacent to the particle separation device (42) within a wall of the casing (40).
