1. a trouble-shooter is used to comprise the machinery and equipment with respect to the rotary part of static component, and this trouble-shooter comprises:

  • Drive unit is used for driving to rotate this parts;

    The test section is fixed to these parts or static component, and comprises in following at least one;

    At least one vibrational system sensor in vibration transducer, sound transducer, ultrasonic sensor and the AE sensor;

    WithTemperature sensor;

    AndSignal processing is used for from determined the state of these parts by the detection signal of test section output;

    Wherein work as these parts at 100min -1Or faster and 1500min -1Or when rotation in the slower rotational velocity range, this signal processing is diagnosed the fault of these parts based on the vibration or the temperature detection signal of test section.
