HIGH ENTRAINMENT VENTURI FOR RANDOM ORBITAL SANDER DUST COLLECTION

摘要

A venturi nozzle (1) for high entrainment vacuum use for random orbital sanderdust collection having a nozzle design which improvesthe nozzle jet (10) to promote a uniform velocity profile (7) across thediameter of the jet nozzle (1) as well as a thin shear layer (6) byproviding a shallow angle nozzle (1) approach, a smooth transition flow intothe nozzle throat (2) and an accurate nozzle departure radius(3).
