Basic Knowledge of Air and Piping: What is Vacuum?

The state of air where the density of air molecules is smaller than that of the atmosphere! A detailed explanation about vacuum is provided.

Around us, there is air in a state called "atmospheric pressure," and it can be surprisingly easily utilized by creating a state of vacuum. The state of air with a lower density of air molecules than the atmosphere is called "vacuum," and since the pressure (when considered as gauge pressure) is lower than that of the atmosphere, it is referred to as "negative pressure." The purposes of utilizing vacuum can be broadly divided into two categories: "utilizing pressure difference" and "utilizing vacuum space." 【Two Purposes of Utilizing Vacuum】 ■ Utilizing Pressure Difference - Extracting force from the pressure difference between the atmosphere and vacuum to perform tasks such as workpiece transportation. - Particularly effective for workpieces that are difficult to grasp. ■ Utilizing Vacuum Space - Removing unwanted gas molecules to create a pure space for physical or scientific phenomena to occur. - Preventing troubles caused by substances like oxygen. *For more details, please refer to the PDF document or feel free to contact us.
