随着我国石油化工和宇航工业的飞速发展,转动轴的线速度V和被密封介质压力P越来越高。今后相当长一段时期内,流体密封特性稳定化的问题,仍是科研使用单位的重大课题。这无非是从材质及结构两方面去解决稳定性。
With the rapid development of China’s petrochemical and aerospace industries, the linear velocity V of the rotating shaft and the pressure P of the sealed medium are getting higher and higher. For a long period of time in the future, the problem of the stabilization of the fluid sealing properties will remain a major issue for the scientific research units. This is nothing more than to solve the stability from both the material and the structure.
