Vertical high-speed bearing impeller mechanism

The invention relates to a vertical high-speed bearing impeller mechanism in the field of energy and power. The vertical high-speed bearing impeller mechanism comprises a rotating shaft, a mechanical bearing, a bearing vertical blind hole, a bottom end axial direction supporting piece and at least one impeller mechanism; all the impeller mechanisms are arranged on the rotating shaft and are arranged in a shell in the up-down direction; between every two adjacent impeller mechanisms, the shell and the rotating shaft are rotationally arranged in a sealed manner; the bearing vertical blind hole is vertically formed in the shell; one end of the rotating shaft is arranged in the bearing vertical blind hole; the mechanical bearing is arranged between the rotating shaft and the side wall of the bearing vertical blind hole in the radial direction; and the bottom end axial direction supporting piece is arranged between the lower end of the rotating shaft and the lower bottom of the bearing vertical blind hole.
