Abstract

The knapsack sprayer is a very popular equipment, due to its low acquisition cost and wide applicability. In recent years, electric backpack sprayers, which increase the operator’s comfort and improve the spraying operation quality, have come up. This study aimed at evaluating an electric backpack sprayer, by using four flat spraying nozzles (XR 110.02, AXI 110.03, AXI 110.04 and AXI 110.05). The variables studied were: liquid flow and pressure, battery charge duration, axis rotation and pump noise. The electric sprayer provided constant flow and pressure for the XR 110.02, AXI 110.03 and AXI 110.04 nozzles. By using the AXI 110.05 nozzle, a variation was observed for the liquid flow and pressure, mainly at the end of each repetition, since the flow increase also increased the pump power demand. Similarly, the battery charge duration was proportional to the power demand. For the flows studied, the pump noise fitted the regulation standards, for a daily working journey of 8 hours.
