梅县发电厂４台磨煤机的主轴在高温介质中产生热位移，使轴瓦与主轴颈之间－温度升高，破坏了轴瓦与主轴颈之间形成的润滑油膜，导至烧瓦。通过检查和处理主轴的误差，将轴瓦按主轴的冷态安装位置和热态稳定位置进行研磨，确保了主轴与轴瓦都能接触良好，并留有足够的膨胀间隙。处理后的磨煤机在以后的长期运行中，轴瓦状况良好，证明上述措施是行之有效的。 Meixian Power Plant 4 mill coal spindles in the high temperature medium heat displacement, so that between the bearing bush and the main journal - the temperature increases, the destruction of the bearing bush and the main journal formed between the lubricating film, leading to the burning tile. By checking and handling spindle errors, the bush is grinded in the cold-mounted and hot-staged positions of the spindle to ensure that both the spindle and the bush are in good contact and with sufficient expansion clearance. After the treatment of coal mill in the long run in the future, the bearing in good condition, proves that the above measures are effective.
