Factors affecting the discharge pressure of centrifugal compressors
Thread Content
The pressure driving the turbine is 4.0 MPa; does that mean the pressure at the compressor outlet will not exceed 4.0 either?
Theoretically, no, because the shaft transmits force, not pressure.
The steam pressure driving the turbine is 4.0 MPa; therefore, the pressure at the outlet of the compressor driven by the turbine is independent of this pressure~~~~~~~~~~
The inlet pressure can be high; it can even exceed certain levels, and the flow rate can also be set at a specific value
Compression ratio of each cylinder stage, temperature of the compressed gas
