description The utility model relates to a seal structure of a centrifugal compressor, in particular to a helical-toothed labyrinth seal; each seal tooth of the labyrinth seal is a helical tooth; one side of each seal tooth is vertical to a central line of a centrifugal compressor spindle and the other side of each seal tooth is inclined to the central line of the centrifugal compressor spindle; and a front inclination angle of each seal tooth is an acute angle of 45-65 DEG, preferably 55 DEG. According to the labyrinth seal disclosed by the utility model, each seal tooth of the labyrinth seal is designed into the helical tooth, so that the sealing performance and the work efficiency of the centrifugal compressor unit are improved.
