The rotor lobed, radial clearance calculation, end play orientation and adjustment, the determination of the meshing clearance between two rotors pressure angle of the Root's blower used for PTA conveying was discussed. 对PTA输送用罗茨鼓风机的转子叶型,径向间隙的计算,轴向间隙的定位,调整和两转子压力角位的啮合间隙的确定进行了讨论。
Through simulation tail trace of upstream blade end wall by smoke, it summarize sweep effect of blade on smoke flow and the rule of the clearance leakage flow under different speed, the smoke flow diffuser angle decrease and the deflection angle increase as the rotor speed up. 通过烟雾模拟上游叶片端壁尾迹,总结出不同转速下叶片对烟雾流的掠扫效应和间隙泄漏流动的规律,随着转子转速的提高,烟雾流扩散角减小,偏转角增大。
