Abstract

Improving the repair service system is becoming more and more important task in various industries. Damage from undersupply of heat energy to consumers is greatly reduced when decreasing time from the moment of damage occurrence in the centralized heat supply systems to detection and correction of this corruption. Thus, to reduce prejudice and for successful solution of problems of resource saving the time limit for the recovery period is of considerable importance. This is the urgency of the task. The work in the field of resource saving deployed in the Russian Federation in the past years makes the task of nationwide scale. The main aim of the study is to analyze the repair and maintenance documentation elements of the district heating of the large cities in the Russia Federation; to classify defects, to create and to process database of defectiveness. The methods used in the study. The authors have used the advanced statistical treatment of results and experimental studies; methods of probability theory and mathematical statistics. When developing the databases of damage and work with them the software packages Microsoft Access database and Excel, Autodesk AutoCAD, Statistica were used. The results. Based on the data collected by the heating system of the 21 cities in the Russian Federation the authors carried out a comprehensive analysis of damage: according to the terms of exploitation; on the elements of the heat supply system; for reasons of appearance, the elements and depending on the laying method. The weak points were identified and the causes of elements damage in the district heating systems were established.
