In the world of agricultural machinery, one of the most underestimated factors is that related to absorption.
In agriculture, among the most widely used machinery, thesprayer is the one with the most variables that the farmer must know in order to obtain the best result, established together with, and also with, his agronomist.
In fact, this tool is used to spray plants with a formula of water and plant protection solution, distributed in droplet form after passing through the nozzle, creating a mixture of liquid and air.
Precisely because of the variety of components, this tool needs different arrangements in order to provide the farmer with the desired result, ensuring a good yield as far as the product is concerned and a reduction in costs resulting from poor use, especially as far as drift is concerned.
However, this tool needs the study of a vital component to arrive at its intended purpose: power absorption.
What is power absorption in agricultural machinery
The agricultural sprayer works by means of a fan apparatus that pushes, through nozzles, a liquid solution contained in a reservoir into a sprayed form in a targeted area, reducing drift.
Today many agricultural entrepreneurs look to drift to test the effectiveness of the sprayer, however, absorption is also an important parameter in understanding the effectiveness of the machine.
In technical terms, absorption is defined as the ratio of gas flow rate to the pressure the impeller yields to it.
In other words, this definition refers to the amount of air pressure the fan can push.
High power absorption generated by the fan apparatus, does not allow it to develop the high performance that would allow the mixture to penetrate properly on the target, as well as within the thickest vegetation thus leading to higher consumption of pesticide, increasing costs related to pesticides and wear and tear on the fan, and all its component parts.
In practical terms, some of the inhaled air remains inside the conveyor, thus creating an internal “air plug,” resulting in decreased performance and results.
In contrast, low absorption allows the fan to throw out more air, promoting more effective machine performance. This factor greatly affects the performance of the fan apparatus and the effectiveness of the phytosanitary treatment
Therefore, the farmer should prefer a sprayer with a low degree of absorption in order to achieve the desired performance, safeguard the farm tractor, and reduce fuel consumption.
