vacuumpump working principleS BY WEST TECHNOLOGY
A vacuumpump is a device that removes gasmolecules from a sealed volume to create a partial vacuum. The working principle of a vacuumpump is based onthe principle of creating a pressure difference betweentwo connected spaces. The pump essentially pumps gasmolecules from a low-pressure area to a high- pressure area, effectively creating a vacuum inthe low- pressure area.
There are several typesof vacuumpumps, butthey all work onthe same basic principle of removing gasmolecules from a sealed volume. Some of the most commontypesof vacuumpumps include
Positive displacement pumps: These pumpsuse mechanical actiontotrap gasmolecules and move them fromthe low- pressure area tothe high- pressure area. Examplesof positive displacementpumps include rotaryvane pumps and screwpumps.
Momentumtransferpumps: These pumpsuse high-speed jetsof gas totransfermomentumtothe gas molecules inthe low-pressure area, which propelsthemtowardsthe high-pressure area. Examplesof momentumtransferpumps include diffusionpumps and turbomolecular pumps.
