| Abstract: | The change
laws of the axial thrust of the rotor in the high pressure cylinder of a CO2 centrifugal
compressor in the working condition of various rotary speeds and flow rates were studied,the
accident cause of axis damage of the rotor in the high pressure cylinder of a CO2 centrifugal
compressor in the starting process was revealed based on measuring the performance curves
of the impellers of the rotor.Some methods of controlling the axial thrust and preventing the
axis damage were proposed for the characteristics of 520000t/a urea plants in production. |
