What Are The Main Parameters Of The Vacuum Pump?

(1) Air extraction rate: the air extraction rate of the vacuum pump is also called the production capacity. At a certain temperature, the volume of gas that the vacuum pump can extract from the equipment in unit time, expressed in m3/s or m3/h.
(2) Residual pressure: also known as limit vacuum, which is the lowest pressure that the vacuum pump can reach under a stable state, expressed in "Torr" or%. 1Torr=1/760atm=133.3Pa。
(3) Air extraction volume: under a certain temperature, the vacuum pump can extract the specified gas from the equipment in a unit time, which is called air extraction volume (m3/h).
(4) Starting pressure: the pressure when the vacuum pump starts to work.
