  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. Turbopump - Wikipedia

    en.wikipedia.org/wiki/Turbopump

    Generally, axial pumps tend to give much lower pressures than centrifugal pumps, and a few bars is not uncommon. Their advantage is a much higher volumetric flowrate. For this reason they are common for pumping liquid hydrogen in rocket engines, because of its much lower density than other propellants which usually use centrifugal pump designs.

  4. Vacuum pump - Wikipedia

    en.wikipedia.org/wiki/Vacuum_pump

    In the field of oil regeneration and re-refining, vacuum pumps create a low vacuum for oil dehydration and a high vacuum for oil purification. [44] A vacuum may be used to power, or provide assistance to mechanical devices. In hybrid and diesel engine motor vehicles, a pump fitted on the engine (usually on the camshaft) is used to produce a vacuum.

  5. Turbocharger - Wikipedia

    en.wikipedia.org/wiki/Turbocharger

    In an internal combustion engine, a turbocharger (also known as a turbo or a turbosupercharger) is a forced induction device that is powered by the flow of exhaust gases. It uses this energy to compress the intake air, forcing more air into the engine in order to produce more power for a given displacement .

  6. Diffusion pump - Wikipedia

    en.wikipedia.org/wiki/Diffusion_pump

    An oil diffusion pump is used to achieve higher vacuum (lower pressure) than is possible by use of positive displacement pumps alone. Although its use has been mainly associated within the high-vacuum range, down to 1 × 10 −9 mbar (1 × 10 −7 Pa), diffusion pumps today can produce pressures approaching 1 × 10 −10 mbar (1 × 10 −8 Pa) when properly used with modern fluids and accessories.

    Most general pumps can increase as well as decrease the pressure of a gas; however, this category contains pumps that are usually exclusively used to decrease pressure. Wikimedia Commons has media related to Vacuum pumps .

  8. Velocity triangle - Wikipedia

    en.wikipedia.org/wiki/Velocity_triangle

    An example of a velocity triangle drawn for the inlet of a turbomachine. The "1" subscript denotes the high pressure side (inlet in case of turbines and outlet in case of pumps/compressors). A general velocity triangle consists of the following vectors: [1] [2] V = absolute velocity of the fluid. U = blade linear velocity.

  9. Roots blower - Wikipedia

    en.wikipedia.org/wiki/Roots_blower

    An Eaton M62 Roots-type supercharger is visible at the front of this Ecotec LSJ engine in a 2006 Saturn Ion Red Line.. The Roots-type blower is simple and widely used. It can be more effective than alternative superchargers at developing positive intake manifold pressure (i.e., above atmospheric pressure) at low engine speeds, making it a popular choice for passenger automobile applications.
