摘要(Abstract):

迷宫密封是产生大型透平机组失稳的一个主要因素。作者从理论和实验得到了迷宫密封的压力分布、激励力和动力特性系数;研究了偏心、进气预旋、转子转速、进出口压力差和其它参数对它们的影响。
This paper described the pressure distributions, the fluid forces and the dynamic characteristic coeffcients of labyrinth seals by both theory analysis and experimentresults, and studied the influences of the following parameters, such as eccentricity, entry swirl, rotor speed, pressure difference between inlet and outlet and so on.
