Axial flow compressor casing

The utility model discloses a casing of an axial flow compressor. The casing is provided with a first casing body, an auxiliary supporting plate is at least arranged at the end part of the first machine shell body along the radial end surface in an extending manner, and a hoisting hole is formed in the auxiliary supporting plate; and a lifting lug which is spaced from the auxiliary supporting plate and extends along the radial end surface is arranged at the end part of the first machine shell body. According to the technical scheme, after the upper machine shell is turned over, a stable supporting point is achieved, and the stability of the machining process is improved. After the upper machine shell is overturned, the connecting pipe at the top of the upper machine shell is effectively protected, and damage to the connecting pipe is avoided. The convenience of the upper casing in the dismounting process is improved, and the maintenance height required by the upper casing is reduced. 本实用新型公开了一种轴流压缩机机壳，设置第一机壳体
