摘 要: 从N S方程出发 ,推导了气体端面密封泄漏量的计算公式 ,计算了两种不同槽形气体端面密封在不同的操作压力和轴转速下的泄漏量 ,建设了气体端面密封的专用试验平台 ,并在试验台上对试验密封的泄漏量进行了试验研究。 A leakage equation of the gas seal was derived based on Navier-Stockes Equation. The leakage of two kinds of gas seal was calculated for different and rotate speeds of the shaft. A special test equipment was setup and the leakage of the seal was tested.
