Study On Vibration Signal Analysis Method Of Air Compressor

Centrifugal compressor is the main type of air compressor, is one of the large-scaleproduction of the main driving force responsible for the production plant wind-drivenmachinery and ventilation mechanical power supply missions, the size of their equipment,the price is more expensive, in the event of failure, will not only cause huge economiclosses and returned to the safe production a huge hidden. Based on CSPC in NovoPharmaceutical (Shijiazhuang) Co., Ltd."to reduce equipment failure rates from liftingequipment efficiency", this thesis focused on solving the frequent failure of large-scaleequipment and imported equipment, the problem of high maintenance costs. Sensor signal,remote transmission and fault diagnosis are used in the necessary analysis for monitoringthe status signal through the signal conditioner. Wavelet transform and, the HHT methodsignal processing and data analysis active the function of data show. Therefore, it isnecessary to establish a large centrifugal compressor operating status monitoring and faultdiagnosis system to ensure reliable air compressor, security, and economic operation.In-depth understanding and research of centrifugal air compressor monitoring thestatus and fault mechanism and the type of fault on the basis of the data acquisition systemand the remote information transmission system, the centrifugal compressor runningparameters transmitted over the network to monitoring center, the centrifugal compressorremote real-time status monitoring; In order to achieve the function of the centrifugalcompressor fault diagnosis, a centrifugal compressor fault diagnosis method based on BPnetwork, that the air compressor vibration signal for the analysis of objects.In this thesis, a remote large centrifugal air compressor condition monitoring andfault diagnosis system is developed. In November2012the system basically completedand running so far in good condition, the performance is relatively stable, reaching remotecondition monitoring of large-scale centrifugal compressor fault diagnosis function forlarge centrifugal compressor safe, reliable and efficient operation provides a strongguarantee.
