2021年9月30日 · The main objective of an eductor is to take the volume of any fluid out of the system by maintaining a system pressure upstream. The main objective of an ejector is to maintain a system vacuum upstream. Eductors usually have a high compression ratio as compared to ejectors.
A vacuum ejector, or simply ejector is a type of vacuum pump, which produces vacuum by means of the Venturi effect. In an ejector, a working fluid (liquid or gaseous) flows through a jet nozzle into a tube that first narrows and then expands in cross-sectional area.
