Abstract

A support system useful to interconnect interstage components in a centrifugal compressor. The system allows controlled balancing of pressure induced forces while accommodating thermal expansion and contraction. In one preferred form a support ring is mounted about a scroll volute but supported through tie rods from a conduit concentrically aligned with the volute. A second support ring is mounted about the conduit, facing but spaced from the first ring, and supported from the volute. The support rings are respectively sealed to the volute and conduit through O-rings which allow sliding axial motion. A grooved peripheral pipe coupling seals the space between the support rings. The surface area of the support rings can be selectively chosen to direct and control pressure forces within the compressor system.
