本机组推力头与主轴为一体结构，由于水机轴提前已吊入机坑，在发电机主轴吊入前应确
认水机轴顶面法兰的高程应高于设计高程 5 ㎜左右（如下图所示：水机轴与发电机主轴的联轴法兰
面设计安装高程为 EL:89.600m， 现场实际在水机轴吊入机坑前在转轮下部放入调整垫板将水机轴的
上法兰面高程调整为 EL:89.605m 即可） ，若水机轴顶面法兰高程低于设计安装高程，那么发电机
主吊入后推力头悬挂在镜板上，两根轴法兰面间有间隙，发电机轴与水轮机轴将不能连接，这样就
造成“第十二章节”中转子吊入前的大轴对中无法进行

The unit head and spindle structure as a whole, since water axis advance into the pit, in front of the generator shaft into theRecognize water shaft height should be higher than the design height of the top flange about 5 mm (as shown in the following figure: coupling flange water shaft and generator spindlesDesign installation height for the EL:89.600m, site in front of the shaft into the pit of water in the lower part of the wheel shaft into the riser block water machineFlange surface elevation can be adjusted to EL:89.605m), if the shaft flange on the top of water height below the design and installation of elevation, then the generatorInto the thrust hanging on the mirror plate, shaft flange there is a gap between the two, the generator shaft connected to the turbine axis will not be able to, thusResulting in "the 12th chapter" hanging into the shaft of the rotor is not possible

The spindle head and the thrust unit is an integral structure, because the water has been lifted into the pit shaft in advance, in the main shaft of the generator should be confirmed before hangingRecognize water shaft top flange height should be higher than the design elevation of 5 mm or so (as shown below: water shaft and the main shaft of the generator shaft coupling flangeSurface design installation elevation for EL:89.600m, live in water shaft hanging into the machine pit in the lower part of the wheel into the adjustment plate water shaftFlange surface elevation adjustment to EL:89.605m). If water shaft top flange elevation below the design installation height, so generatorMain crane into thrust head hanging on the mirror plate and between the two shaft flange gap, the shaft of the generator and turbine shaft will be unable to connect, soIn the twelfth chapter, the main shaft can not be carried out before the rotor is hoisted into the front of the rotor.
