Abstract

1,042,713. Centrifugal compressors. SHELL INTERNATIONALE RESEARCH MAATSCHAPPIJ N.V. March 4, 1964 [March 6, 1963], No. 9220/64. Heading F1C. [Also in Division G3] A method or apparatus preventing surge in a centrifugal compressor comprises a compressor 1 which delivers through a cooler 4 and condensate trap 5 to an outlet pipe 8 and a valve 10 controlling a by-pass 9. The pressure at the outlet (or inlet) is measured at 13 and the flow in the outlet (or inlet) is measured as the pressure drop across an orifice or Venturi 11. The flow and pressure signals are fed to and compared in a proportional controller 15a having a narrow band and a proportional-integral controller 15b having a wider band. The output of the two controllers are fed to a relay 16 which provides an output to control the by-pass valve 10. The relay 16 transmits a signal which represents the larger signal of the controllers 15a or 15b in the sense of opening the valve 10.
