Is described the method of approximate calculation of the functional characteristics of gas-pumping units and the method of diagnostics of the value of the impairment of the working wheel of the central center of the main gas pipelines is described. It is clear that the deposits are inflated with the impairment of productivity and productivity, and that is efficiency factor of superchargers. The architecture of the program complex is described, as well as the necessary system and technical facilities for carrying out the transfer for fragmentation at the warehouse of the automatic transmission system of the gas transmission system. Experimentally, the accuracy of the value of the radial prominence in the gaps of the working wheel on the buttstock of the "Demag" 655 P2 type was verified. The revision of the growth rates from the results of the straight lines to the open flow part was not shifted 0.15 mm. Descriptions of the method of implementation by a complex of programs, allow to carry out the development of the main indicators of the functional and technical mill of the VCN GPA: vitreous-pressure, forceful, polytropic KKD characteristics. These indicators are used for the purpose of determining the overall performance of the energy efficiency of the robotic skin GPU: the effective effort of the gas turbines, the vitrates of the fired gas from the of the coated gas pump, which is displayed in the real demand. The economics of the robotics of compressor stations, the supply of the pumped gas, the confirmation of the plans for the supply of gas to the residents and the safe functioning of the gas transportation system (GTS) of Ukraine, a significant world of possessing the functional To this, it is of particular importance to build up the development of new methods and to provide diagnostics, to ensure that the actual FCS possesses an assessment. At present, there is evidence of the actual state of possession of a more efficient operation of the plant in the transition from a traditional technical service to a resource-saving one. The obtained results show that the calculation of the actual characteristics of the VCN using the proposed method allows to take into account the influence of seal wear on the actual parameters of the regime over the entire range of workloads of single-stage and multistage superchargers.
