N2 - Compressor is a kind of key equipment in petroleum industry, chemical industry and other industries, among which centrifugal compressor is relatively widely used. The vibration caused by rotor wear is a main factor leading to the failure of centrifugal compressor. Therefore, a method to evaluate the reliability of compressor by monitoring the vibration signal of compressor rotor is proposed. First, the vibration signal of the compressor rotor is collected through the vibration sensor and preprocessed; Second, empirical mode decomposition is carried out, which decomposes the vibration signal into intrinsic mode function components; Third, the information entropy of intrinsic mode function components is calculated; Fourth, the health degree is calculated. According to the Euclidean space distance formula, the Euclidean space distance between a vibration sample and the reference value of the rotor is calculated and converted into health degree; Last, the reliability of centrifugal compressor is evaluated.
