摘要

FIELD: oil and gas industry.;SUBSTANCE: group of inventions relates to the oil and gas industry. In cooling method of GTP gas compressor unit engine is provided with protective casing, which is supplied to discharge and exhaust air ducts. Air is taken from the atmosphere through air intake and is fed to the bottom of the casing. Through the distribution box up to 20 % of the supplied air is supplied for the snail space of the gas outlet GTP gas compressor unit. Rest air is fed directly under the engine body. Deflection of air jets supplied to the lateral areas of the engine body, produce a guiding apparatus with tilted stationary in the cooling process of engine valves. Doors are made with aerodynamic profile and is adjustable fixed on the power element. should be at least two doors on each side of the engine. Doors set in pairs within each group of unidirectional rejected with the mirror symmetry of the tilt response of the group of doors. Process of adjusting the position of the doors is carried out by a step change of the angle α_as. attacks. What for in the cross section doors are emit two points. One point is given the function of a rotation pivot with a limited angle of rotation within the accepted range of angular positions of the door. Through another point, a radial indicator of the angle of attack is carried out, numerically determined on a scale with a given step of angular positions of the door. Then put the rest doors, turn on air flow and produce a uniform cooling of the working engine.;EFFECT: technical result achieved by the group of inventions is to reduce the circumferential unevenness of the engine surface temperature, increase resource and reliability on all working conditions of GTP as a part of gas compressor unit.;10 cl, 6 dwg, 1 tbl
