| 摘 要： | 某电厂1号600 MW超临界机组在商业运行中,由于1B引风机轴承故障紧急停运,致使1号机降出力至350 MW运行。其主要原因是1B引风机运行中中间推力轴承承受较大的摩擦推力,润滑脂过热变质致使润滑效果下降,造成轴承(隔离架)长期磨损损坏。详细介绍了引风机运行中出现机械故障的状态诊断、原因分析,并全部更换了质量更为可靠耐用的新轴承,制订了切实可行的预防措施,以保证机组的安全运行。

| Abstract: | Some power plant NO.1 600MW supercritical unit in commercial operation,due to 1B induced draft fan bearing emergency stop,resulting in NO.1 unit derated to the 350MW.The primary reason is during the 1B induced draft fan operation, the middle thrust bearing withstanding big friction thrust force,the lubricant overheated deterioration and lubrication effect drops causes the bearing(isolated frame) the long-term attrition damage.It introduces in detail in mechanical breakdown diagnosis of induced draft fan ope... |
