Abstract

We have calculated the power necessary to operate sprayer fans at different gears by measuring torque and revolutions per minute on the PTO shaft of tractor during the operation of two different versions of radialfan sprayers. We have established that the older generation of sprayers (A) with the fan operating in second speed requires the power input of 68 kW on the PTO shaft of tractor, while the required power in normal operation amounts to 54.9 kW. The required power can either be reduced to 31.4 kW by using a lower gear of the first speed or it can be reduced by using a new generation of sprayers (B) that use radial fans of more recent generation. On average, the first fan speed of such sprayers requires the power of 24.5 kW, while the
second fan speed of such sprayers requires the power of 31.8 kW. The user can reduce due required power and thus energy consumption by selecting the optimal operating mode or by using the new generation of sprayers. This not only contributes to significant economic savings related to energy consumption in permanent crop production, but at the same time positively effects the environment because it decreases the emission of carbon dioxide (CO2).
