在对离心风机静止模型的进口流场分析的基础上,通过用导流板进行试验,得到了最佳位置。然后用导流圈在已知性能的风机上进行测试,效率明显提高。
Based on the analysis of the inlet flow field of centrifugal fan stationary model, the best position was obtained through the experiment with the deflector. Then use the diversion ring on the fan with known performance test, the efficiency is obviously improved.
