  2. Vacuum ejector - Wikipedia

    en.wikipedia.org/wiki/Vacuum_Ejector

    A vacuum ejector, or simply ejector, or aspirator, is a type of vacuum pump, which produces vacuum by means of the Venturi effect.. In an ejector, a working fluid (liquid or gaseous) flows through a jet nozzle into a tube that first narrows and then expands in cross-sectional area.

  3. Jet aerators - Wikipedia

    en.wikipedia.org/wiki/Jet_aerators

    Jet aerators can be installed either as submersible units or piped through the tank wall using an external dry-installed chopper pump to feed the aspirating ejector(s). Jet aerators are easily configured into any basin geometry including circular, rectangular, looped reactors and sloped wall basins.

    en.wikipedia.org/wiki/Propelling_nozzle

    A simple example of ejector nozzle is the fixed geometry cylindrical shroud surrounding the afterburning nozzle on the J85 installation in the T-38 Talon. [11] More complex were the arrangements used for the J58 and TF-30 installations. They both used tertiary blow-in doors (open at lower speeds) and free-floating overlapping flaps for a final ...

    Piping and instrumentation diagram of pump with storage tank. Symbols according to EN ISO 10628 and EN 62424. A more complex example of a P&ID. A piping and instrumentation diagram (P&ID) is defined as follows: A diagram which shows the interconnection of process equipment and the instrumentation used to control the process.

  6. Surface condenser - Wikipedia

    en.wikipedia.org/wiki/Surface_condenser

    Diagram of a typical modern injector or ejector. For a steam ejector, the motive fluid is steam. For water-cooled surface condensers, the shell's internal vacuum is most commonly supplied by and maintained by an external steam jet ejector system. Such an ejector system uses steam as the motive fluid to remove any non-condensible gases that may ...

  7. Vacuum pump - Wikipedia

    en.wikipedia.org/wiki/Vacuum_pump

    The Roots blower is one example of a vacuum pump. A vacuum pump is a type of pump device that draws gas particles from a sealed volume in order to leave behind a partial vacuum. The first vacuum pump was invented in 1650 by Otto von Guericke, and was preceded by the suction pump, which dates to antiquity. [1]

  8. Venturi scrubber - Wikipedia

    en.wikipedia.org/wiki/Venturi_scrubber

    Figure 1 - Venturi scrubber Ejector venturi scrubber. A venturi scrubber is designed to effectively use the energy from a high-velocity inlet gas stream to atomize the liquid being used to scrub the gas stream. This type of technology is a part of the group of air pollution controls collectively referred to as wet scrubbers.

  9. Injector - Wikipedia

    en.wikipedia.org/wiki/Injector

    Diagram of a typical modern ejector. An additional use for the injector technology is in vacuum ejectors in continuous train braking systems, which were made compulsory in the UK by the Regulation of Railways Act 1889. A vacuum ejector uses steam pressure to draw air out of the vacuum pipe and reservoirs of continuous train brake.
