本文通过对所研制的斜流式风机在不同顶端间隙下进行的实验研究,探讨了斜流叶轮顶端间隙对风机性能的影响,以及La氏效率下降关系式对准三元翼形斜流叶轮的适用性。
In this paper, through the experimental study on the diagonal flow fan developed at different tip clearances, the influence of tip clearance of the diagonal flow impeller on the performance of the fan and the relationship between the decline of La’s efficiency and the inclined flow impeller applicability.
