大直径回转轴密封元件的性能研究

The Research on the Performance of Sealing Element in A Large-Diameter Rotary Shaft

本文对大直径回转密封件沿轴向的压力分布、泄漏量随压力的变化规律进行了测试 ,并且利用有限元理论及流体动力润滑理论对密封件进行了理论计算 。

The paper tests the axial pressure distribution and leakage rate, with the change in pressure, for a large-diameter rotary shaft The sealing element has been calculated by finite element method and hydrodynamic lubrication theory, with revealing the sealing mechanism
