摘要(Abstract):

针对传统填料密封结构刚性不足和径向力与压盖距离呈指数规律递减的现象,开发了一种自适应回弹填料密封,即在填料中增加开口空心金属环作为支撑件。通过有限元分析得出此密封结构弥补了传统填料密封的缺点,增加了石墨填料密封耐高压的效果,同时可以增加径向力,降低预紧力,在某些工况下可以取代机械密封。
Aiming at the traditional packing seal insufficient foundation rigidity and radial force diminishes exponentially with the distance of gland,a newly packing sealing structure opening and hollow metal ring supporting is designed. By the finite element analysis the disadvantages are divided and the packing seal high pressure resistant effect of the traditional packing seal is added.The radial force is increased,preload is reduced,and the mechanical seals can be replaced in certain condition.
