The effect of the type of sprayer bodies on the obtained coefficient of variation of sprayed liquid deposition

Abstract

In this work, the study results of retention uniformity of sprayed liquid deposition obtained from three kinds of nozzles mounted in sprayer bodies of various constructions were presented. For the tests, a five-spray body with a rotation axis of a spigot parallel to the sprayed surface, a three-spray body with a retention axis perpendicular to the sprayed surface and one-spray body were used. Changes in individual spraying nozzles were done by three operators. It was stated that the biggest differences in repeatability and reproducibility of adjustments were noted for five-spray bodies, however, minimum changes not exceeding the value of one percentage point were noted for single bodies. For triple bodies repeatability of obtained CV regardless of mounted nozzles changed maximum up to 1,5 percentage point and reproducibility of measurement changed from 0,5 to 0,8 percentage point.In this work, the study results of retention uniformity of sprayed liquid deposition obtained from three kinds of nozzles mounted in sprayer bodies of various constructions were presented.
