Diagnostics of thermal condition of electromechanical machinery

The paper is devoted to studying issues of machinery thermal state monitoring using generalized approach to objectives of electromechanical system (EMS) diagnostics based on current temperature values. Generalized mathematical model of EMS (a homogeneous body or a multi-weight estimated heat balance diagram) for various operation conditions of a facility allows to identify diagnostic indicators (criteria) for taking specific measures to stabilize its operation. Increasing efficiency of the facility thermal state monitoring can be achieved using noncontact measuring instruments to determine temperature distribution over the facility surface. Temperature distribution over an EMS facility surface enables concluding on maintenance necessity. For effective application of noncontact thermal-imaging equipment for diagnostics of EMS on the basis of the provisions presented in the paper, training program for specialists in thermometering of industrial facilities has been developed.
