Overview of Vacuum Technology
Vacuum technology mainly devotes to establish a physical environment, where the pressure is lower then atmospheric pressure so that craft production, physical measurement and scientific experiments.
The vacuum technology also includes four aspects– vacuum acquisition, vacuum measurement, leak hunting and vacuum application which are mutually reinforced in the development of vacuum technology.
The timeline has been summarized as the chart below.
|Time Point (approx.)||Event|
|In 1643||An Italian physicist Torricelli found that atmospheric and atmospheric pressures in vacuum and natural space have been existing all the time.|
|In 1650||Otto von Grick from Germany made the piston vacuum pump.
In 1654, he conducted the famous Madelberg hemispheric experiment in Madelberg.
|In the late 19th Century||The success of the British Industrial Revolution greatly promoted the development of vacuum technology.|
|In the early 20th Century||The appearance of vacuum tubes speeded up the development of vacuum technology.|
|after 1940||Vacuum technology has become a separate discipline whose application is expanded to nuclear research (separation of cyclotron and isotope), vacuum metallurgy, vacuum coating and freeze-drying.|
