CHANGES OF COEFFICIENT OF VARIATION OF TRANSVERSE LIQUID DISTRIBUTION FOR SINGLE AND DUAL STREAM ATOMIZERS

The aim of the study was to clarify the influence of the height, the setup of an angle of the boom sprayer and the pressure of liquid on the value of the coefficient of variation of the transverse liquid distribution. Single XR 11003 VP and dual TJ 6011006 VS stream atomizers were used in the study. Nozzle spacing on the boom sprayer was 0.5 meters. The average temperature of water used to this test was 14 degrees C. The measurement of the coefficient of variation of the transverse liquid distribution was performed using an automatic groove table Hardi Spray Scanner with groove resolution of 100 mm. The final result was expressed by the coefficient of variation of the transverse liquid distribution according to ISO 5682-3. Regardless of the use of the single or dual stream atomizers the strongest impact on the value of the coefficient of variation of the transverse liquid distribution had the height of the boom sprayer, then the angle of the boom setup and the smallest the pressure of the liquid. Regardless of the combination of the analyzed variables the use of the dual stream atomizers results in a reduction of the coefficient of variation of the transverse liquid distribution in relation to the use of the single stream atomizers. Deflection of the boom sprayer at the angle of 5 degrees significantly increases the value of the coefficient of variation of the transverse liquid distribution. For the single and dual stream atomizers they were 8.56 % and 9.07 %, respectively.
