摘要
零逸出上游泵送机械密封是指带缓冲流体系统的上游泵送机械密封 ,可以实现被密封流体的液相零泄漏和气 (汽 )相零逸出。借助无限窄槽理论对零逸出上游泵送机械密封进行了性能分析 ,并初步给出了该密封的设计步骤、方法及相关的设计内容 ,希望有助于指导该密封的工业开发。
Theoretical analysis approved that the upstream pumping mechanical seals can achieve zero emission of sealed medium with barrier fluids On the basis of narrow groove theory, the face film pressure distribution and critical radius of zero emission upstream pumping mechanical seals was derived; Furthermore, the design procedure of seals was given
