| 摘 要： | 用实验方法研究了交错式篦齿在不同的齿数、轴向间隙比和径向间隙比的条件下，泄漏量随篦齿前后压力比的变化规律。通过分析得到了几个有价值的结论。总结提出了计算其泄漏量的经验公式。计算结果与实验数据吻合良好。

| Abstract: | The influencing factors and correlations on flow parameter of iterlacing labyrinth are investigated in experiments. The factors include number of restrictions, ratio of restriction's thicknessto clearance about axis direction and diametrically and pressure ratio. A number of valuableconclusions have been drawn on basis of analyses. Empirical expressions for leakage are formulated.The agreement of calculation with experimental data is good. |
