Vacuum ejector Wikipedia
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 crosssectional area The fluid leaving the jet is flowing at a high velocity which due to BernoulliPiping sized incorrectly can also contribute to nozzle loading in the same manner, with oversized pipework creating excessive vertical forces Nozzle loading can create stresses across pipework, pump s and supports In centrifugal pumps, these stresses may distort pump casings, and lead to excessive wear of shaft sleeves and bearingsExplanation of nozzle loadings and how to minimise them
