单双级旋片真空泵的自动转换装置

Automatic switching device of single and double rotary vane vacuum pumps

讨论了传统双级旋片真空泵的不足 ,论述了用串并联方案提高双级旋片真空泵的性能 ,并提出了实现双级旋片真空泵串并联的两种可行的方案 。

In this article, the shortcomings of the traditional vacuum pumps with double rotary vane and an improvement on the performance of double rotary vane vacuum pumps by series parallel connection are discussed, and two feasible ways to realize series parallel connection of vacuum pumps with double rotary vane are put forward, thus, the performance of pumps gets better.
