Product Summary

Turbo molecular vacuum pump is the most successful application of Active Magnetic Bearings (AMB). Digital control technology based on digital signal processor (DSP) was introduced to AMB.It is a type of vacuum pump, superficially similar to a turbopump, used to obtain and maintain high vacuum. These pumps work on the principle that gas molecules can be given momentum in a desired direction by repeated collision with a moving solid surface. In a turbo molecular pump, a rapidly spinning turbine rotor 'hits' gas molecules from the inlet of the pump towards the exhaust in order to create or maintain a vacuum.

In a turbo molecular vacuum pump with a high vacuum-side induction area and of a rotational symmetrical arrangement, comprising a compressor turbine including a rotor and a stator tube having axially alternately tightly arranged rotor blade rings and stator vane rings with oppositely oriented blade and vane surfaces, a pre-vacuum chamber with a gas guide structure for the connection of a pre-pumping system, a drive module and a bearing unit, the turbo-molecular pump has a center area with a central coaxial open space extending from an ambient end to the high vacuum-side induction area and the open space is closed at its end adjacent the ambient end thereof by a flange in a vacuum-tight manner or is connected to a vacuum recipient, and the high-vacuum end of this space is separated from a pre-vacuum space.

For many applications, it would be advantageous if the central area around the turbine axis of a turbo molecular vacuum pump would be freely accessible also during operation, or if the recipient, extending at least partially around the turbo molecular vacuum pump, would be accessible in this area and/or if the pumping-active annular area could be differentially increased or a concentrically differential pumping would be possible.
