摘　　要：动、静涡旋盘之间的泄漏是影响涡旋真空泵抽气性能的重要因素,分析了主要由轴向间隙及径向间隙引起的气体返流泄漏,阐述了相应的密封原理及措施,为涡旋真空泵的优化设计提供新的思路。The leakage between the fixed and orbiting scrolls is considered to be a vital factor which influences the pumping performance of a scroll vacuum pump , the reflux leakages which mainly caused by axial clearance and radial clearance was ana -lyzed, the relevant sealing principles and methods were expound , so as to provide some new minds for the optimal design of a scroll vacuum pump .

关 键 词：真空泵 泄漏 密封
