2. Turbomolecular pump - Wikipedia

   en.wikipedia.org/wiki/Turbomolecular_pump

   Most turbomolecular pumps employ multiple stages, each consisting of a quickly rotating rotor blade and stationary stator blade pair. The system is an axial compressor that puts energy into the gas, rather than a turbine, which takes energy out of a moving fluid to create rotary power, thus "turbomolecular pump" is a misnomer.

3. Roughing pump - Wikipedia

   en.wikipedia.org/wiki/Roughing_pump

   The term "roughing pump" derives from the vacuum range it works in, "rough vacuum", above 1x10 −3 torr (0.1 Pa). Pumps that operate in the high vacuum ranges typically don't operate, or only operate inefficiently, at atmospheric pressures, whereas pumps that work efficiently at atmospheric pressure usually cannot produce a vacuum lower than ...

4. Turbomachinery - Wikipedia

   en.wikipedia.org/wiki/Turbomachinery

   Pumps are used to move fluids around using some sort of mechanical power, from electric motors to full size diesel engines. Pumps have thousands of uses, and are the true basis to turbomachinery (Škorpík, 2017). Air compressors - Air compressors are another very popular turbomachine. They work on the principle of compression by sucking in and ...

5. Compressor map - Wikipedia

   en.wikipedia.org/wiki/Compressor_map

   Alternatively the map of a similar compressor can be suitably scaled. This article is an overview of compressor maps and their different applications and also has detailed explanations of maps for a fan and intermediate and high-pressure compressors from a three-shaft aero-engine as specific examples.

6. Scroll compressor - Wikipedia

   en.wikipedia.org/wiki/Scroll_compressor

   A scroll compressor (also called spiral compressor, scroll pump and scroll vacuum pump) is a device for compressing air or refrigerant. [1] It is used in air conditioning equipment, as an automobile supercharger (where it is known as a scroll-type supercharger ) and as a vacuum pump .
