A method for replacing the
petal of a runner chamber of a vertical
turbine unit and a device for measuring and
grinding the runner chamber, the method comprises: making a new runner chamber,
cutting the petals of the new runner chamber,
processing the assembled
petal body, preparing the
petal body before installation, installing the petal body, grouting, and measuring and
grinding the new runner chamber. The method realizes efficient replacement of the runner chamber and inspection of the inner wall of the runner chamber, and the parameters of the runner chamber are precisely controlled. The device comprises two cross-shaped brackets, a rotating shaft, two
flange bearings, two sets of adjustment parts, a rotating frame, two limit studs, a measuring and
grinding mechanism, four precision linear guide rails and a precision slide block; the new runner chamber in the vertical
turbine unit is in a non-contact state with the cross-shaped bracket, and the cross-shaped bracket is welded with the guide blade bottom ring and the tailwater
pipe in the vertical
turbine unit; through the adjustment part, the axis of the rotating shaft coincides with the center line of the new runner chamber, and the
flange bearing is positioned; the measuring head and the grinding head of the
angle grinder point to the inner wall of the new runner chamber. The device has a reasonable structure and is easy to use.
