摘要
针对山西右玉电厂330MW直接空冷机组空冷风机单元振动问题,对风机单元进行了测试和分析,给出了风机、减速机及风机桥架的振动规律。通过采取风机桥架加固、将风机由5叶改为6叶等措施,消除了空冷风机单元振动故障。此次振动故障的处理过程及相关试验结果,对风机单元设计及施工具有一定的借鉴意义。
Aimed to the vibration fault of air-cooling fan in 330 MW direct air-cooling units in Shanxi Youyu Power Plant, the vibration rule of fan, reducer and fan bridge is gained through a series of analyses and tests on fan. The vibration fault of air-cooling fan could be eliminated by some measures, such as the reinforcement of fan bridge, and changing the fan blade number from 5 to 6. These vibration fault treatments and test results could provide references for fan＇s design and construction.
