IMPROVING THE RELIABILITY OF COMPRESSOR EQUIPMENT FOR AIR SEPARATION UNITS
The article examines the piston compressor. The problem of reliability and trouble-free, safe operation of compressor equipment is touched upon. A method for improving reliability, reducing accidents by replacing intake and discharge valves. The aim of the work was to study the statistical operational parameters of reciprocating compressors to obtain their reliability characteristics. The analytical base was the operational data of reciprocating air separation compressors of one of the Russian oil refineries. Based on this, an analysis of their physical wear and tear was carried out and the probability of failure-free operation and failure rate were obtained.The dynamics of accidents and injuries during the operation of equipment under excessive pressure is analyzed. We found that according to Rostekhnadzor data for 2012-2017, there were 19 accidents and 15 fatal accidents. For example: unsatisfactory quality of installation and repair work on equipment operating under excessive pressure, leading to a violation of the technology of installation and repair of equipment and, as a result, to its destruction due to the presence of defects made during installation and (or) repair; poor quality of technical inspection, technical diagnostics and industrial safety expertise of equipment, including the performance of these works without visual inspection and assessment of the actual condition. In this regard, the issue of safe, trouble-free operation of compressor equipment at oil refineries in Russia remains relevant.To reduce the energy intensity of technological processes, energy-saving measures are currently being developed and implemented to improve the reliability and energy efficiency of equipment operation. At the facilities of the fuel and energy complex, various equipment is used, one of the main ones used in many industries is compressors for compressing gases.Monitoring with an analysis of the main parameters of the piston compressor operation and performance indicators in the factory parameters can be taken as a basis for early repair, at the same time, satisfactory values of the parameters can serve as a basis for increasing the inter-repair period. The dependences of reliability indicators obtained in this work can be used to plan the time of repairs of piston units from the condition of minimizing costs.
