The invention discloses a gas compressor with damping boss guide vanes. The gas compressor is composed of a machine body assembly, a supercharging device and a servo motor. The supercharging device isinstalled between a gas inlet and a main gas chamber of the main body assembly, gas supercharging is achieved, the supercharging process is stable, energy consumption is low, and high supercharging is achieved according to practical requirements. The servo motor is installed on the outer wall side of a shell. The guide vanes adopted in the gas compressor are simple in structure, damping bosses inthe middles of the guide vanes and the vanes are assembled to be in an annular shape to restrict each other, rigidity is increased, the inherent frequency of the vanes is changed, the bending torsional stress of the roots of the vanes is reduced, damping boss combined faces of the guide vanes are sprayed with wear resisting alloy, and the damping effect can be achieved during vibration of the guide vanes.
