Abstract

An apparatus for testing the sprayer performance has been designed and manufactured at AEnRI, Rice Mechanization Center (RMC), Meet EI-Dyba, Kafr EI-Sheikh Govrnorate. The apparatus was used to evaluate the distribution pattern knapsack sprayer through measuring characteristic operating parameters. The apparatus consists of main frame equiped with no:.zie carrier, adujsting. high bar, manometr, electric motor, belts drive and driven pullies, this combination has been accumulated so. as to receive the distribution surface (patternator) which is inclined with an angle of 45° with the harizontal. Consequently the spray fluid collected plastic bottIs representing the actual amount of spray fluids for each nozzle. This procedure indicated the spray patterns in terms of symmetry, maximum and minimum point. The apparatus also, automatically control and measure the spray pattern of the fluid at surface area of 1 m2 and also it can measure the movement speed of the fluid. The rsults of study included the determination of coefficient of variation, percentage of minimum point, percentage of maximum point, coefficient of symmetry, coefficient of uniformity, distribution characteristics, time and axial deposit rate and deposit efficiency. The performance of the sprayer was tested under different variations of : spray height (200, 300, 400 and 500 mm), spray pressure (500, 1000, 1500 and kPa) and nozzle diameter (0.57, 1.0 and 1.5 mm). A maximum value of deposit rate (3.516 L/min.) was obtained at orifice diameter of 1.5 mm, spray height of 200 mm and spray pressure of 2000 kPa, while having the orifice diameter of 1.0 mm, spray height of 200 mm and pray pressure of 2000 kPa gave the maximum value of deposit efficiency (97.85 vo). The best uniformity of the distribution pattern obtained with orifice diameter -1.0 mm, spray height of 500 mm, nozzle space of 500 mm,and spray pressure of 2000 kPa and any skewing about that tends to deteriorate the spray pattern.
