Key Points for Selecting a Vacuum Pump
1. The ultimate pressure of the vacuum pump should meet the working pressure of the process. Typically, the ultimate pressure of the pump is chosen to be about an order of magnitude lower than the process requirements; 2. Each type of pump has a certain working pressure range; ...
Vacuum is not "empty"! Scientists may have discovered a fourth mode of heat transfer.
We all know that there are three main modes of heat transfer in real life: convection, conduction, and radiation. In a vacuum, however, due to the absence of a medium, heat cannot be transferred.
