推力轴承是水轮发电机的重要部件之一,其工作状况,直接影响水轮发电机运行的可靠性,也影响到它们运行的灵活性。目前,国内外均普遍采用巴氏合金作为推力瓦的轴承合金。为了保证这种瓦可靠和灵活的运行,一般在设计和制造以及在电站安装中采用各种办法,在运行中采用许多保护性措施,使巴氏合金和镜板之间形成液体摩擦,即在巴氏合金和镜板两者之间保持一定厚度的油膜,通过油膜的承载能力,将转动部分的整个轴向荷载(包括轴向动水压力)传递给推力瓦,以避免巴氏合金和镜板之间直接摩擦。
Thrust bearing is one of the important components of hydroelectric generator, its working conditions, directly affect the reliability of hydroelectric generator operation, but also affect the flexibility of their operation. At present, the Babbitt alloy is widely used as the bearing alloy of thrust bearing both at home and abroad. In order to ensure reliable and flexible operation of such tiles, various measures are generally employed in the design and manufacture as well as in the installation of the power station, using many protective measures during operation to bring about liquid friction between the Babbitt and the mirror plate, Babbitt and the mirror plate to maintain a certain thickness between the oil film, through the oil film bearing capacity, the rotating part of the entire axial load (including axial dynamic water pressure) to the thrust pad to avoid the Babbitt and mirror Direct friction between the plates.
