Studies of the Nozzle for Use of Chemical Spraying (VI)

Comparative Experiments Relate to the Characteristics of Nozzles for Use of Mist Sprayer (II)

Abstract

Two nozzles for used of mist sprayer have been studied, in this paper the author has been investigated to an impact propeller type and an impact plate type nozzle on the experimentally especially, regarding the characteristics of its atomization, arriving force, dispersion, distribution. The experiment has been carried out under the same condition as V. reports. and as result the following have been obtained: -
For an impact propeller type nozzle, the drops which was atomized was effected largely by the propeller shape, blade and air velocity. And its distribusion showed a diffusing form. To an impact plate type nozzle, a drops size was changed by the mutual relation of plate size and nozzle diameter. That is a peculiality of this nozzle structure, and its distribution showed both diffusing and large arriving form by the selection of its impact plate and nozzle size. Active energy in this drops was large, and so its arriving force was powerful.
