丹江电站1机组水轮机导轴承原设计是采用巴氏合金,黄油滑润。因设计安装质量问题,十几年来运行中常出事故,影响发电。因此,决定对它进行技术改造,并获得了良好的效果。这项技术改造,是将黄油润滑改为水润滑;巴氏合金轴承改为中硬耐磨橡胶轴承,在大轴润滑部位加包一层具有防锈性的1Cr18Ni9Ti不锈钢(图1),并且是在不拆开顶盖,施工场地只有宽370毫米、高1070毫米的狭窄道中进行
Danjiang Power Station Unit 1 turbine guide bearing the original design is Babbitt, butter lubrication. Due to the design and installation of quality problems, more than 10 years often run out of accidents, affecting power generation. Therefore, it decided to carry out technological transformation and achieved good results. The technical transformation is to change the butter to water lubrication; Babbitt bearings to hard wear-resistant rubber bearings, lubricated parts in the shaft with a layer of anti-rust 1Cr18Ni9Ti stainless steel (Figure 1), and is Without dismantling the roof, the construction site is only narrow 370 mm wide and 1070 mm high
