摘要

FIELD: oil and gas industry.;SUBSTANCE: group of inventions relates to oil and gas industry. Gas compressor unit contains consistently reported on the working fluid: air intake path, gas turbine installation with an inlet device for supplying air from the air intake chamber to the entrance to the gas turbine engine, exhaust gas exhaust path, gas compressor and cooling system of gas turbine engine. Inlet device includes a pipe with an aerodynamic inlet nozzle having a socket with a longitudinal section configuration of the fragment lemniscate type with a gradient of G_BX.h decreasing cross-sectional area of the flow part at the nozzle length from F_{max f.p} To F_{min f.p}, defined in the range of values G_BX.h = (1.15÷1.58) [m²/m]. WU pipe is made assembly and includes spacer plates, hermetically connected through flanges, and support rings for attachment to the support complex. Support complex includes a guide beam placed under the WU pipe, which is adjustable at one end through a lanyard and with a support frame. Front end of the beam is movably supported by a fixed rack, which is provided with a support wheel in the upper part with the possibility of axial mounting and operational movements of the WU pipe.;EFFECT: technical result of the group of inventions is to improve the reliability, efficiency and service life of gas compressor unit by improving the design, aerodynamic and energy parameters of the inlet device.;10 cl, 10 dwg
