The invention provides a method and system for detecting a vibration signal of a driving shaft of a gas compressor. The method comprises the steps that the vibration signal of the driving shaft is obtained; driving shaft vibration amplitude signals corresponding to all sampling moments are separated out of the vibration signal of the driving shaft, a target detecting value of the driving shaft vibration amplitude within a sampling period is generated according to the driving shaft vibration amplitude signals and comprises the maximum instant change rate, the accumulative change rate and / or variance; the maximum instant change rate, the accumulative change rate and / or the variance are compared with respective preset alarm threshold values; if the maximum instant change rate, the accumulative change rate and / or the variance reach the respective preset alarm threshold values, early warning information of the gas compressor is generated and sent out. According to the technical scheme, reasonable detection and early warning can be carried out on the driving shaft vibration amplitude, therefore, failure early warning is carried out on the gas compressor, related operating personnel are reminded to carry out treatment, and economic losses caused by failures of the gas compressor are avoided.
Description
technical field [0001] The invention relates to the technical field of gas compressor detection, and more specifically, to a detection method and system for a vibration signal of a drive shaft of a gas compressor. Background technique [0002] As a part of industrial equipment, gas compressors are becoming more and more sophisticated. With the improvement of the precision of gas compressors, the probability of damage to gas compressors also increases accordingly. The drive shaft is one of the core components of gas compressors. , the vibration of the drive shaft is an important sign to detect the operation of the gas compressor, so the vibration signal of the drive shaft of the gas compressor can reflect the operation of the gas compressor. [0003] Before the failure of the gas compressor, the vibration signal of the drive shaft often has certain abnormalities, and the possible failure of the gas compressor can be predicted by detecting these abnormalities. In the prior ar...
