本文介绍两种我们使用和设计制造的用于蒸汽流泵(油扩散泵,油增压泵)油锅蒸汽压和泵油饱和蒸汽压测定的试验装置。 一、油锅蒸汽压的测定 油扩散泵的油锅蒸汽压1～3托,油增压泵的油锅蒸汽压10～15托,有的达数10托。为了测量这些泵的油锅蒸汽压的具体数值,可采用图1所示的装置进 This article describes two test devices that we used and designed to measure the vapor pressure of the oil pan and the saturated vapor pressure of the oil in a steam flow pump (oil diffusion pump, oil booster pump). First, the determination of the oil vapor pressure of the oil pan oil diffusion pump steam pressure 1 ~ 3 Torr, the oil booster pump steam pressure 10 ~ 15 Torr, and some up to 10 Torr. In order to measure the specific values ​​of the oil vapor pressure of these pumps, the device shown in Figure 1 can be used
