How Does a Vacuum Pump Work Diagram

The vacuum in the pump is forced to move through pipes or holes in the wall, like the power supply for our space vehicle, the air pump we will use to push back the air from the spacecraft and supply it with fresh air inside the vacuum container beyond that. Under pressure, electrons and heavy nuclei can more easily move through molecules of certain materials in the vacuum. These molecules are compressed to a small fraction of their normal volume, equivalent to the compression force of a perfect vacuum removing the atoms from the medium.
