迷宫密封为减少涡轮发动机的漏流,静止部件和转动部件间的间隙越小越好。但间隙减小,摩擦接触的风险就增加。在这种情况下,在静止部件上安装一个密封的工作间隙结构或涂层以减小接触摩擦时对转动部件的破坏。常用的耐磨结构是金属蜂窝体,其耐磨性 Labyrinth Seal To reduce turbine engine leakage, the smaller the gap between the stationary part and the rotating part, the better. However, as the clearance decreases, the risk of frictional contact increases. In this case, a sealed working gap structure or coating is mounted on the stationary part to reduce damage to the rotating part upon contact with the friction. Commonly used wear-resistant structure is a metal honeycomb body, its wear resistance
