摘要： PURPOSE:To obtain high exhaust performances by constructing a screw groove vacuum pump with an upper flow side and a down flow side pump step, and arranging a thrust gas bearing close to the exhaust side of the down flow side pump step. CONSTITUTION:An upper flow side and a down flow side pump step constructing a screw groove vacuum pump are provided with impellers 21a,23a of a centrifugal compression pump and stationary side disks 21b,23b, and impellers 22a,24a of a Siegbahn compression pump and stationary side disks 22b,24b respectively. And a ceramic rotor 2 is supported with a thrust gas bearing 12a and an upper radial gas bearing 9 and a lower radial gas bearing 11. Thereby compression in radial direction can be carried out with respective Siegbahn compression pumps in multiple steps, hence even when screw groove gaps are large, a high compression ratio can be obtained to enlarge the exhaust speed. In addition, by arranging the thrust gas bearing supporting the rotor of the screw groove vacuum pump close to the exhaust side of the down flow side pump step, thermal deformation and centrifugal deformation of the thrust gas bearing can be reduced to obtain high exhaust performances.
