Functionality Evaluation of Air Blow Nozzles

Abstract

In many factories, compressed air is used to blow off water, oil, or cutting chips. If this could be done efficiently with greater blowing power, in many cases production processes would flow more smoothly and production costs could be reduced. As an aspect of air blow system selection, air blow nozzles were studied and a functionality evaluation of the air blow nozzles commonly used in factories was carried out. As a result, it became possible to discriminate between good and bad nozzles and select an optimal nozzle with reduced pressure drop and improved air-blowing power.
