A method and an apparatus for predicting the deterioration trend of a rotating machine

The utility model discloses a method and an apparatus for predicting the deterioration trend of a rotating machine. According to absolute standards and relative standards in China and abroad and a specific condition of a device, the apparatus determines the deterioration limit value (shutdown value) of the device. Through online continuous measurement or offline regular measurement of parameters including vibration, rotating speed, load, temperature, and pressure of the rotating machine, current status of the device is automatically analyzed in virtue of an artificial intelligence expert system. According to the property of a fault, the degree of influence on the deterioration trend of the device is determined and the deterioration trend (shutdown time) of the device is regularly predicted. The apparatus for predicting the deterioration trend of a rotating machine is capable of directly displaying a predicted result and an influence factor, employing a preventive measure, effectively preventing a risk caused by a process from quantitative to qualitative change of the device status, and reducing loss caused by unreasonable advanced or delayed shutdown.
