Roots centrifugal compressors deliver high
Radial - Tilt Pad Bearing
Axial - Multi-Shoe Equalizing
Bearing
BEARINGS: Tilt Pad, Sleeve and Integral Squeeze Film Damper (ISFD)
type bearings are used in the radial (journal) orientation, while
Tapered Land and Multi-Shoe Equalizing are used in the axial
thrust) orientation. Bearing type is selected dependent upon
the compressor type.
IMPELLERS: Offered in many different designs and
constructions of several different materials, depending upon
the operating conditions and gas being handled. The impeller
is statically and dynamically balanced and then oversped to
15% above maximum operating speed. The impeller is then
mounted on the shaft with a suitable locking device and the
rotor assembly is dynamically balanced.
