Diagnostics of the technical condition of pumping equipment by thermal control method

The article discusses methods for diagnosing the technical condition of pumping units using a thermal imager in the operating conditions of JSC NAC KazAtomprom. In the framework of this study, we used a sample of diagnostic information obtained by thermal imaging examination of SULZERcentrifugal pumping units subject to a technical condition assessment procedure. A technique for conducting thermal imaging diagnostics on existing equipment is described. To analyze the dataobtained, thermogram processing methods were used to identify areas of local overheating, indicatingpotential defects. The results of thermal imaging analysis of bearing assemblies of pumping units are presented. The conducted studies have made it possible to form basic diagnostic signs for assessing the technical condition based on thermal characteristics, which ensures the creation of a single diagnosticcriterion for assessing and predicting the condition of centrifugal pumping units. The results obtained demonstrate the high efficiency of the thermal imaging method for earlydetection of malfunctions and assessment of the remaining life of the equipment. This, in turn, helps to improve the reliability of pumping units, reduce the risk of accidents and optimize maintenanceregulations. The presented methodology can be recommended for widespread implementation inenterprises with a similar type of equipment, as well as used in a technical condition monitoring systemwithin the framework of the predictive maintenance concept.
