摘要(Abstract):

通过对渐开线型三叶罗茨风机的设计参数的分析,计算出了径距比Rm/a与面积利用系数λ、理论流量Qth、实际流量Qs及容积效率ηv的相关曲线,并确定了径距比Rm/a的合理选择范围。
The relation between design parameters of the three leaves Roots blower is disscussed.The curves which describe the relation of radius-center distance ratio and area utilized coefficient,theoretical flow,actual flow,volume efficiency η_v are calculated respectively.Finally the reasonable bound for radius-center distance ratio of the three leaves Roots blower is determined.

关键词(KeyWords): 三叶罗茨风机;径距比;流量特性
