2X rotary vane vacuum pump (referred to as rotary vane pump) working pressure range of 101325 ~ 1.33 × 10-2 (Pa) belong to the low vacuum pump. It can be used alone or as a foreline pump for other high-vacuum or ultra-high vacuum pumps. It has been widely used in metallurgy, machinery, military, electronics, chemicals, light industry, petroleum and pharmaceutical production and research departments.
Rotary vane pump can be sealed off the sealed container of dry gas, if accompanied by gas-town device, you can also pump a certain amount of condensable gas. However, it is not suitable for the extraction of gases that are highly oxygenated, corrosive to metals, react chemically to pump oils and contain particulate dust.
Rotary vane pumps are one of the most basic vacuum acquisition devices in vacuum technology. Rotary vane pump for small and medium-sized pump. Rotary vane pump has a single-stage and two-stage. The so-called two-stage, is the structure of two single-stage pump in series. Generally made more double-stage, in order to obtain a higher degree of vacuum.
The relation between pumping speed and inlet pressure of rotary vane pump is as follows: Under the inlet pressure of 1333Pa, 1.33Pa and 1.33 × 10-1 (Pa), the pumping speed shall not be less than 95% of the nominal pumping speed of the pump respectively, 50% and 20%.
