运行中的立轴半伞式水轮发电机,由于推力轴承油槽内有负压,推力头与镜板外壁将带动油运动,将油上吸,油将从油槽盖板缝隙中逸出,使定子线卷下端部出现油珠。为解决这一问题,我们自制一挡油筒,安装于油槽盖板加工面上,将其密封,使溢油集中,另设置一回油管使集油流回油槽见 Vertical shaft half-running hydroelectric generator in operation, due to negative pressure in the thrust bearing oil tank, the thrust head and the outer wall of the mirror plate will drive oil movement, the oil will be sucked, the oil will escape from the crevice of the oil tank cover so that the stator Oil roll appeared at the bottom of the coil. In order to solve this problem, we made a self-made oil tank, installed on the processing surface of the oil tank cover, sealed it to concentrate the oil spill, and set a return pipe to make the oil collect back to the oil tank
