并列运行的轴流风机的喘振研究

Study on Surging Observed in Shunt Connected Axial Blower

该文利用流体网络法 ,计算了并列的两台轴流风机的动态运行情况 ,找出了并列运行两台轴流风机发生喘振的临界动叶角度差。结果表明 ,当并联运行的两台轴流风机的动叶角度差小于其临界动叶角度差时 ,风机不会发生喘振。图 2表 1参

Using the network method of fluids, an operation mode of two shunt connected axial blowers is being calculated as well as the critical angle difference of moving blades, at which surging of the blowers may occur. Results show that, as long as the moving blade angle difference of the two blowers or kept within critical bounds, no surging of the blowers will occur. Figs 2, table 1 and refs 4
