组合式空心转子渗漏对油封式旋片真空泵抽气效率的影响

Influence of Built-up Hollow Rotor's Leakage upon Efficiency of Oil-sealed Sliding Vane Rotary Vacuum Pump

组合式空心转子由于轴头与转子体之间的结合面存在着渗漏 ,使泵的抽气效率性能下降 ,从而影响其在应用中的效率。本文简要分析了其产生的原因并提出了改进措施。

As there were leak on contact place between shaft and rotor body in built up hollow rotor, dropping discharg gas speed of pump and efficiency applied of oil sealed sliding vane rotary vacuum pump. In the paper mainly analyzed the reasons and advanced ways to solution.
