液膜密封

With an experimental method, the liquid film pressure between the two faces and the seal face temperature rising are measured and analyzed for a double spiral groove mechanical seal.
通过实验方法，研究了内外双螺旋槽机械密封端面间的液膜压力和端面温升。
According to the basic assumptions, liquid film pressure over a pore column can characterize one over the integrated seal face.
根据基本假设，一个孔栏上的液膜压力分布可表征整个密封面上的液膜压力。
When there exists width in seal face of friction pairs there will exist pressure drop in the liquid leaking direction. When the temperature rises liquid film will be gasified. The gas-liquid phase or pure gas will exist between the seal faces.
摩擦副的密封面设计有宽度，液体在泄漏方向上有压力差，温度升高，造成液膜汽化，密封面间出现汽液混相或全汽相，膜压增大推开密封面。
The liquid film pressure distribution of a mechanical seal with a face spirally grooved from the inner are investigated in this paper, by the use of me finite difference method, an analytic method and validated by experimentally measuring.
本文用有限差分数值方法、解析计算方法研究了适用于液相介质环境的端面内侧开螺旋槽机械密封端面间的液膜压力分布规律，并进行了实际测量。
