Hello everyone,
Recently I've experienced some problems with a centrifugal compressor presenting subsynchonous vibration due to aerodynamically induced forces, most probably diffuser rotating stall.
The vibration starts at low flows, but within the operational range. Amplitude is not reaching...
Hello guys,
I have some questions about the damped unbalanced response analysis that api requires for centrifugal compressors.
The rotor of this compressor has 7 impellers between the bearings (no overhung impellers).
Api says that, for conical modes an unbalance shall be added at the location...
