摘　　要：以某混流立式水轮发电机组(推力轴承布置为悬式)为例,利用实测得到机组转动部分相对下沉量(相对停机状态)对水轮机水推力进行计算,为电站在线监测水轮机水推力提供一种新手段。Take a vertical Francis turbine unit(which has an suspension thrust bearing) as example,to calculate hydro-thrust of turbine based on deflection(relative to static state) of rotary parts.It is a new method for online monitor hydro-thrust of hydraulic turbine in power station.

关 键 词：轴向水推力 转动部分下沉量 机架轴向刚度系数 水推力在线监测
