There are some reference effect in design of other types of diffusion pump.

对设计其他类型的扩散泵具有一定的参考作用。

The device is equipped with a cryogenic pump, an oil diffusion pump and a mechanical pump.

该机抽气系统由低温泵、扩散泵和机械泵组成。

It can be used alone, can also be used as booster pumps, diffusion pumps, molecular pumps pump before use.

它可以单独使用，也可作为增压泵、扩散泵、分子泵的前级泵使用。

Therefore, it applies to diffusion pump for the pre-pump, but also for supporting precision instruments and laboratory use.

所以，它适用于作扩散泵的前级泵，而且更适用于精密仪器配套和实验室使用。

In this paper, the cause of speed of KT-150 diffusion pump are analyzed in the construction with using the theory of aerodynamics.

本文运用气体动力学的理论，重点从结构上分析了影响KT - 150型扩散泵的抽速因素。
