分析了气膜密封的端面几何结构及其刚度与自振稳定性的内在关系 ,认为2 88型端面气膜密封工业产品的长期正常稳定工作是由于采用了具有很高气膜刚度的螺旋槽顺流泵几何结构的结果
The inherent relationship between the geometric structure of the gas-tight seal and its stiffness and natural vibration stability is analyzed. It is considered that the long-term normal stable operation of the industrial product with the gas-tight seal of the 2 88-type is due to the adoption of a spiral groove with high gas film stiffness Flow pump geometry results
