Abstract

PURPOSE:To heighten the operation efficiency of a centrifugal compressor under capacity control, by providing a linkage in the slit of the diffuser vane of the compressor to drive the diffuser vane and inlet guide vane in connection with each other and by determining the form of the slit in terms of a prescribed formula. CONSTITUTION:The diffuser vane 25 of a compressor is provided with a slit 28 which does not extend in parallel with a camber line 15 defined by a formula DELTAbetax=DELTAl/Lx where DELTAbetax denotes the difference between betax (diffuser vane angle determined by link) and betax' (optimal mounted angle of diffuser vane), DELTAl denotes the distance between camber line and center of guide pin in slit and Lx denotes the distance between center of guide pin and tip of diffuser vane at inlet guide vane angle of theta. The guide pin 29 secured on an adjuster ring 22 is slidably inserted in the slit 28. The adjuster ring 22 is interlocked with the driving inlet guide vane 4 through a linkage consisting of a link 19, a pin 20 and so forth. According to this constitution, when the flow rate of the compressor is changed by altering the angle of the inlet guide vane 4, the mounted angle of the diffuser vane 25 can be equalized to the angle of inflow to the vane in connection with the change in the flow rate.
