Experimental Study on Spray Uniformity of Spraying Machinery

Abstract:

Spray distribution uniformity is a very important performance of nozzle. This paper analyses the spray uniformity of the spraying machinery as well as the influence factors. Spray distribution coefficient of variation of nozzles varies with the different spray pressure, spray pressure and spacing. The nozzles of lechler ST made in German were tested to present the optimum spray height with different spray pressure and spray spacing through analyzing the trend of coefficient of variation varying with the different spray pressure, spray height and spray spacing. By the test, the greatest impact on spray uniformity is the pressure of the spray bar, followed by the height and the spacing of the spray bar. By analysis of the spray distribution coefficient of variation, we find the optimum combination of the spray pressure, spray height and spray spacing.
