详细描述了动叶可调轴流风机喘振故障的发生机理，分析了电厂脱硫增压风机喘振故障原因，认为故障的发生是由于风机后系统阻力增加使管路特性曲线变陡，使风机工作点落入非稳定工况区所致，提出了改善后系统管路阻力的针对性措施。
詳細描述瞭動葉可調軸流風機喘振故障的髮生機理，分析瞭電廠脫硫增壓風機喘振故障原因，認為故障的髮生是由于風機後繫統阻力增加使管路特性麯線變陡，使風機工作點落入非穩定工況區所緻，提齣瞭改善後繫統管路阻力的針對性措施。

The occurring mechanism of surge failure of rotating blade axial - blow fan was described in details, and the causes of surge of desulfurization booster fan in power plant was analyzed. It concluded that the reason of failure was changing of performance curve of pipeline caused by increasing of back system resistance of the fan made the working point of fan move to area of unstable operation conditions. Countermeasures for improving pipeline resistance of back system were raised.
