| description | The utility model discloses a lamp turbine unit runner chamber cavitation surface polishing device which comprises a machine box and a driving motor, and a handle screw rod is connected to the top face of the machine box in a penetrating and threaded mode. The device has the advantages that the moving wheels, the machine case, the handle screw and the grinding wheel are adopted, when the cavitation surface of the runner chamber of the light turbine unit is ground, the device can be moved to the position above the inner wall of the runner chamber of the light turbine unit, and the moving wheels abut against the inner wall of the runner chamber of the light turbine unit in a rolling mode; then, the device can be moved until the grinding wheel is located over the cavitation surface, the driving motor can be started, the handle screw is rotated to push the driving motor and the grinding wheel to move downwards till the grinding wheel makes contact with the cavitation surface for grinding, and during grinding, a w |
