Vacuum chamber

from Wikipedia, the free encyclopedia
Opened vacuum chamber

A vacuum chamber is a hermetic container from which air or other gas (mixtures) can be removed using a vacuum pump .

Vacuum chambers are used, for example, in material testing and foaming technology . Whether electric motors, sensitive sensors or everyday objects such as batteries and accumulators, most components nowadays have to withstand transport in aircraft. To test this beforehand, a so-called height simulation is carried out using a vacuum chamber. Here, a pressure of up to 116 mbar is generated over several hours, which the component must withstand, and pressure fluctuations are also simulated.

In the case of particularly sensitive components, it is advisable to store the material in a vacuum chamber. Due to the vacuum that prevails here, the component is completely independent of the given environmental influences, for example contamination with particles or air humidity is avoided. In addition, vacuum chambers are used in the field of foaming technology. Like many other physical apparatuses, every particle accelerator contains a vacuum chamber (usually not designated as such). In order to eliminate volatile substances from materials, vacuum degassing is carried out in a vacuum chamber .

A widespread use of vacuum chambers is found in waste disposal , where hygienically questionable waste is sealed under vacuum , for example for the disposal of incontinence waste in facilities for the elderly .

The largest vacuum chamber in the world is located in the Glenn Research Center of NASA . It was used as a filming location for the SHIELD headquarters in the movie Marvel's The Avengers .
