Beschreibung
Zusammenfassung:	The invention discloses a gas turbine gas compressor cooling system comprising a cooling pipeline and a conveying device. The cooling pipeline communicates with a conveying pipeline, is located in a vertical face of an engine shaft and corresponds to an engine high-pressure gas compressor stator in position. The cooling pipeline comprises an annular coolant conveying pipeline, a radial coolant conveying pipe and a stationary blade. The stationary blade is installed between a hub of a gas turbine and a case. A hollow stationary blade inner cavity is arranged in the stationary blade. The blade back and blade abdomen of the stationary blade are provided with seepage holes communicating with the stationary blade inner cavity. The stationary blade inner cavity communicates with the annular coolant conveying pipeline through the radial coolant conveying pipe. Through simple pipeline design, effective cooling of gas flow of the medium-high-pressure gas compressor is achieved, and meanwhile, the weight of the cooling
