| description | A compressor system includes a compressor including a bearing supporting a rotating shaft; a sensor configured to measure an index value correlated with a movement of the rotating shaft being made while the compressor is in operation; and a wear-detecting unit configured to detect a degree of wear of the bearing based on a measured value obtained by the sensor. The bearing is a plain bearing, and has a plurality of air gaps arranged at intervals in a circumferential direction such that wear of the bearing changes a positional relationship between an inner circumferential surface of the bearing and the plurality of air gaps and eventually changes a shape of the inner circumferential surface thereof. The wear-detecting unit detects the degree of wear of the bearing based on a change in the measured value caused by a change in the shape of the inner circumferential surface of the bearing. |
