摘　　要：在一定工况下,横流风机在高转速时存在不稳定工作区。本研究在风机试验台上对7种工况,7种转速下的不同压力、风速、流量进行了研究,详细记录了横流风机喘振现象并探讨了工况、转速对喘振现象的影响,为横流风机的正常运行提供了参考依据。Under the certain work condition,the cross-flow fan at high rotate speed soon reveals unsteady work area.This paper experiments on the stage to 7 kinds of work condition in the breeze machine,and 7 kinds of different pressure,wind velocity,and discharges.The cross-flow fan to breathe heavily to flap phenomenon is recorded in detail.The effect of work condition and rotate speed on the breathes heavily to flap phenomenon is studied.The reference basis for the normal movement of the crossc-flow fan is provided.
