Analysis of the effectiveness of using thermal imaging systems to assess the technical condition of pumping units

Abstract

The development of methods for the primary diagnosis of pumping units remains an urgent task due to the low cost of assessing the condition of the equipment. The purpose of the study is to analyze the results of post-repair control of the mechanical and electrical parts of hydraulic units using thermograms. During the study, a test pumping unit with controlled defects of the impeller, coupling, bearing and sealing elements was used. The minimum requirements for diagnostic equipment were evaluated. The data was analyzed both in the presence of defects and after their elimination. The article presents the results of the analysis of thermograms of bearing assemblies of centrifugal pumps and drive electric motors. It is indicated that for an effective analysis of equipment, the minimum resolution of thermal imaging equipment should be no more than 0.1 degrees, which makes it possible to effectively analyze the post-repair conditions of the mechanical part.
