(2) the web transport base is fixed on the basis, web is fixedlyed connected with transport base, and below each stator, do support;
(3) main shaft of slinging, and main shaft fallen to the appropriate location, main shaft is connected with the operating oil line of web;
(4) main shaft is drop to web, and fixedly connected with it;
(5) mounting column on the basis; Have three pillars at least around web;
(6) the lifting support cover puts in place, fixedlys connected with pillar;
(7) hoisting bracket makes the following ring of support fixedly connected with support cover, support go up shaft shoulder apical grafting on ring and the main shaft, and adjust the amount of holding out against with pressure ring;
(8) pull down the pillar that supports support cover, main shaft, support cover, support, web integral body are sling to the machine hole, and web is fixedlyed connected with the parts in the machine hole;
(9) in machine hole, be fixedly connected sequentially support cover and top cover, pull down pressure ring, adjustment support cover and web the position, fixedly connected motor shaft and water arbor, pull down support at last.
Pillar distributing position in the described step (5) is pressed the circumference five equilibrium.
Advantage and good effect that the present invention has are: the present invention is fit to the installation of large-scale axial flow type hydro-turbo generator set, simplicity of design, and fitting operation is convenient, and safe and reliable, versatility is more intense, meets technical requirements.
