Honeycomb sealing technology could make steam turbine unit operation safe and economic due to geometric parameters optimization of honeycomb seals when decreasing radial labyrinthclearance.
Whole model of impeller clearance and labyrinth seal are built up, and the effect of seals with two sides of impeller to axial thrust is considered fully.
建立了叶轮间隙和迷宫密封的整体模型，并充分考虑了叶轮两侧密封对轴向推力的影响。

The study on measuring the clearance of labyrinth now is at the infant stage at home.
