| Abstract: | The rotor is the core component of hydrogenerator unit, which installation directly relates the safe and stable operation of the units. As the developments of design and manufacturing, the size of hydrogenerator tends to be large, and the on-site installation of rotor becomes more difficult. This paper chiefly introduces rotor installation technology of 770MW supersized hydrogenerator unit on left bank of Xiluodu and analyzes its structural characteristic. The stacking process of rotor rim was deeply analyzed and summarized, the specific process scheme of welding main reinforcements was put forward, and the technology of adding shims by heated rim and scheme of adjusting rotor roundness were described in detail. All parameters such as rotor roundness and waviness of hydrogenerator unit have achieved installation standards of Xiluodu power station. It can provide some experience and reference for the rotor installation of million unit. |
