Speed matching issue between turbine and compressor unit
Thread Content
The steam turbine or gas turbine is directly connected to the compressor via a diaphragm coupling, but their rotational speeds differ by over 2,000 revolutions – it’s hard to understand how this can function If it operates at the speed of the original motor, the compressor will be running at almost 50% over speed – could resonance occur? I would be extremely grateful if some expert could explain this principle!
The compressor may come equipped with its own variable-speed gear set
The turbine is equipped with a gearbox, and its speed is the same as that of the compressor.
