ABSTRACT:
A surging prediction device for a centrifugal compressor has a differential pressure detector and a controller. The detector detects a differential pressure between a hub side pressure in the vicinity of an inlet or a diffuser in the centrifugal compressor and a shroud side presser in the vicinity of the inlet of the diffuser. The controller compares the detected differential pressure from the detector with a set differential pressure beforehand set so as to be lower than a surging differential pressure between the hub side pressure and the shroud side pressure at an occurrence time of surging, and outputs a surging signal predicting an occurrence of surging when the detected differential pressure becomes higher than the set differential pressure.
