Abstract

The paper presents relevance of application of non-destructive testing methods in the assessment of technical condition of the mining and oilfield machine components is justified. The prospects of diagnostics of process equipment by the excited oscillations analysis technique are proved. Design and operation algorithm of the multichannel synchronous analyzer Kamerton by LLC NPP ROS (Perm) are described. Methodological bases of defect finding using the multichannel Kamerton analyzer are described. The basic quality criteria characterizing the diagnostics-based state of technical elements are listed. It is proved that the mining and oilfield equipment technical condition assessment method by excited oscillations analysis allows carrying out operative diagnostics of technical facilities without shutdown. This method has no analogues in terms of efficiency compared to the traditional equipment nondestructive testing methods: magnetic particle, metal magnetic memory, ultrasonic flaw detection, ultrasonic thickness measurement, radiographic, metallographic, etc. In some cases, for example, for structures made of heterogeneous materials such as reinforced plastic or reinforced concrete, it is the only possible diagnosis method.
