The history of vacuum technology
In 1643, Italian physicist torricelli discovered that vacuums and natural Spaces have atmospheres and atmospheric pressures.
In 1650, otto von golik of Germany made a piston vacuum pump.
In 1850 and 1865, successively invented mercury column vacuum pump and mercury drop vacuum pump.
At the beginning of the 20th century, vacuum tube appeared, which promoted the development of vacuum technology to high vacuum.
After 1940, the application of vacuum expanded to nuclear research, vacuum metallurgical coating and freeze drying, and vacuum technology began to become an independent discipline.
