All About Vacuum Technology Behind Vacuum Pump, Oven, and chamber

Vacuum technology refers to a process of blank or empty space or space without any matter or a space where the pressure is so low that a particle in the space cannot affect any process in the space to happen. Normally, the vacuum is created by removing the air from the space by a vacuum pump or by fast flow of fluid called Bernoulli’s principle. The vacuum technology was invented by the French physicist, mathematician and philosopher Blaise Pascal in the year 1647-48. The vacuum technology is also popularly known as Pascal’s principle based on the inventor’s name Blaise Pascal.

The process of vacuum is performed due to four basic reasons. First, in order to completely remove the constituents from the space which would, in turn, cause a chemical or physical reaction in the process of melting reactive metals such as titanium. The second reason is to disturb a steady and equilibrium condition in a room or a chamber like removing the volatile liquid or dissolved gas from materials, for example, degassing of freeze-drying, degassing of oil etc. This is also done for desorption of gas from various surfaces like linear accelerators in the manufacture and cleaning up the microwave tubes etc.

The third reason for vacuum is for extending the distance of the travel of a particle before it collides with another particle. This helps the particles in a specific process of moving without collision between the target the source. Some of this is television picture tubes, particle accelerators, vacuum coating etc. The fourth reason for vacuum is to decrease contamination of surfaces caused by vacuum and this is done by reducing the numbers of per second molecular impacts.

An ideal limiting parameter is prescribed for the highest permissible pressure for the process of any vacuum. These parameters can be (1) per unit volume number of molecules as per the above one and two reasons of vacuum, (2) mean free path as per the above reason three of vacuum, and (3) the time needed for monolayer forming as per the above fourth reason of the vacuum.

The first vacuum technology was used for manufacturing electric bulbs in 1900 followed with electron tube, blooming of lens in order to increases transmission of light, preparation of blood plasma for the blood banks, production of titanium. In the course of time, the application of vacuum technology increased to such an extent that it was used in nuclear energy, space simulations and microelectronics.
