Döner Diskli Memede Disk Konum Açısı ve İlerleme Hızının Hacimsel Dağılım Düzgünlüğüne Etkisi

Bu araştırmanın amacı, düşük hacimli pestisit uygulamalarında kullanılan döner diskli memede disk konum açısı (0º ve 30º), ilerleme hızı (0.4 ve 1.2 m s-1) ve memeler arası mesafe (0.6, 0.7, 0.8, 0.9, 1.0, 1.1 ve 1.2 m) faktörlerinin hacimsel dağılım düzgünlüğüne olan etkisini incelemek ve optimum işletme parametrelerini belirlemektir. Laboratuvar koşullarında yürütülen püskürtme uygulamalarında doğrusal hareketli bir püskürtme simülatörü kullanılmıştır. Döner diskin devir sayısı 7000 min-1 ve püskürtme yüksekliği 40 cm olarak ayarlanmıştır. Püskürtme sıvısına 1 g l-1 konsantrasyonda Tartrazine karıştırılmıştır. Uygulamalar 30 l ha-1 norm değerinde yapılmıştır. Örnekleme için 35 mm çaplı petri kutusu kullanılmıştır. Araştırma sonuçlarına göre tüm uygulamalarda püskürtme paterni asimetrik görünümde oluşmuştur. 0° ve 30°’lik disk konum açıları için en düşük varyasyon katsayısı (CV) 0.4 m s-1 ilerleme hızında ve 0.7-0.9 m meme aralığında elde edilmiştir. 1.2 m s-1 ilerleme hızında belirlenen CV ortalamaları 0.4 m s-1 hıza göre daha yüksektir. Ancak disk konum açısı 30º olduğunda 1.2 m s-1 ilerleme hızında elde edilen CV ortalamaları 0º’lik konum açısına göre kısmen iyileşmiştir.

Anahtar Kelimeler:

Effect of Disc Position Angle and Spraying Speed on Volumetric Distribution Uniformity of Spinning Disc Nozzle

The aim of this study was to examine the effect of disc position angle (0º and 30º), spray speed (0.4 and 1.2 m s-1) and distance between nozzles (0.6, 0.7, 0.8, 0.9, 1.0, 1.1 and 1.2 m) on volumetric distribution uniformity, and determine optimal operational parameters in the spinning disc nozzle used in low volume pesticide application. The spray application was performed using a linear moving - spray simulator under controlled laboratory conditions. The revolution of the spinning disc was set to 7000 rpm and the spray height was stable at 40 cm. Tartrazine at 1 g 1-1 concentration was mixed into the spray liquid. The application rate was 30 l ha-1. Petri dishes of 35 mm diameter were used for sampling. According to the results of the research, the spray pattern was formed in an asymmetrical appearance in all applications. For disc position angles of 0° and 30°, the lowest variation coefficient (CV) was obtained at 0.4 m s-1 spraying speed and 0.7-0.9 m nozzle distances. The CV means determined at 1.2 m s-1 spraying speed were higher than 0.4 m s-1. However, when the disc position angle was 30º, the CV means obtained at 1.2 m s-1 spraying speed partially improved according to the 0º disc position angle.
