Compressor Description
The CVGF compressor consists
of three distinct sections: the
two-stage centrifugal
compressor, the motor, and the
gear box with integral oil sump.
See Figure 5.
Compressor
The centrifugal compressor is
two-stage with high-strength
aluminum alloy fully shrouded
impellers. The impellers are
tested at 25 percent over design
operating speed. The rotating
assembly is dynamically
balanced for vibration of less
than 5.1 mm/sec (0.2 ips peak
velocities) at nominal operating
speeds. The control system
affords 20 to 100 percent
capacity modulation by
electrically actuated guide vanes
upstream of each impeller.
