Abstract

PURPOSE: To provide the centrifugal compressor with a surging prevention control device of high performance and energy saving in operation by detecting if the condition is in the state to prevent surging at each stage and by adjusting as needed the inlet guide vane and the diffuser.
CONSTITUTION: The suction flow rate and the discharge pressure detected at each stage by the detector 31 are input into the arithmetic unit 34 of the arithmetic and control unit 32, and they are there compared with the surging prevention line P0 stored in the memory 33. If surging prevention action is judged to be necessary, the angles of the inlet guide vanes 20W23 and the diffusers 24W27 for respective stages are controlled. Further, if it is judged by the arithmetic unit 34 that air discharge control is required, the driving device 30 opens the air discharge valve 28. By repeating this arithmetic and control unit operation in a needed cycle, surging can be prevented before it develops and energy saving in operation can be achieved.
