一、原有轴承温升过高的原因分析 万福河一级电站为引水式电站。工作水头约75米,安装了一台HL702—WJ—50水轮机,其配套电机的型号为SFW118/665—6P。整个水轮发电机组采用三支承的布置形式(图1)。水轮机轴和发电机轴采用刚性连接。在水轮机转轮和飞轮之间的水轮机轴用一个径向推力轴承支承,在发电机轴的二端各装一个径向滑动轴承。全部轴向载荷由水轮机端的径向推力轴承承 First, the original bearing temperature rise reason analysis Wanfu River a hydropower station. Working head about 75 meters, installed a HL702-WJ-50 turbine, the matching motor model SFW118 / 665-6P. The entire hydro-generator set with three bearing arrangement (Figure 1). The turbine shaft and generator shaft are rigidly connected. The turbine shaft between turbine runner and flywheel is supported by a radial thrust bearing with a radial plain bearing at each end of the generator shaft. All axial loads are borne by the radial thrust shaft on the turbine end
