ABSTRACT:
A multistage centrifugal compressor has a shaft rotatable on an axis and a plurality of centrifugal impellers fixed on the shaft and having outlets at outer peripheries thereof. Conduits connect the impellers to from a path for fluid undergoing multi-stage compression by the impellers from a suction side to a delivery side. The conduits including a plurality of diffusers arranged radially outwardly from the impellers, each impeller and associated diffuser constituting a stage. At least two of the diffusers are vaned diffusers provided with vanes having leading edges at their inlet ends. To provide high efficiency combined with low risk of rotating stalls, among the vaned diffusers, the ratio of diffuser vane leading edge radius to impeller outlet radius increases along the fluid path from the delivery of the compressor to the suction side.
