What are Turbomolecular Pumps?
Turbomolecular pumps are momentum transfer devices that get high vacuum conditions by sending kinetic energy to gas molecules. It does this through fast, rotating rotor blades mixed with red with stationary stator blades. These axial compressor vacuum pumps work completely opposite to normal turbines. This is because they add energy to gas rather than taking it away. The multi-stage design quickly compresses gas molecules from inlet pressures around 10^-3 Torr to super high vacuum pressures below 10^-8 Torr.
Core Operating Mechanisms
The rotor-stator blade configuration creates systematic compression through:
- Momentum Transfer: Gas molecules collide with rapidly moving rotor surfaces rotating at speeds up to 90,000 RPM
- Directional Flow: Angled blade geometry directs scattered molecules preferentially toward exhaust direction
- Progressive Compression: Multiple stages achieve compression ratios exceeding 10^8 for hydrogen molecules and 10^10 for N2
Backing Pump Integration
Turbomolecular pump systems require backing pumps including rotary vane, scroll vacuum pump, or dry screw pumps to:
- Evacuate compressed gas from exhaust port
- Maintain optimal fore-vacuum pump pressure conditions
- Enable pump startup from atmospheric pressure
