| Summary: | Research and development work related to the study and use of water spray must certainly be based on the most accurate determination of the dispersion composition of spray droplets. It is just this parameter that forms the basis for all further calculations of the effect of water spray on the process cycle components. The introduction of the method for restoring the original sizes of spray droplets and the most accurate measurement of their disperse characteristics will allow coming close to solving the problem of optimizing the operation of spray technology, as well as will make it possible to predict and possibly regulate the dispersed characteristics of droplet flows. Therefore, it is the foundation for the development of breakthrough and environmentally sustainable resource-saving technologies in the agricultural sector. We have developed a method for restoring the original size of the droplet spectrum (Patent No. 2709402 titled “A method for determining the size of droplets”). Based on this method, a test bench was developed and manufactured to assess the quality of spraying of working fluids. An aerosol chamber design was developed and the chamber was assembled, in which an aerosol sample was taken under conditions of equal probability of deposition and preservation of droplets of all sizes. Software for high-speed measurement of the dispersion characteristics of the spectrum of spray droplets has been developed. In general, the studies performed have demonstrated the appropriate professional capabilities of the experimental facilities when testing sprayers. This gives us an opportunity to come up with a proposal to create centers for testing sprayers for their compliance with the declared performances based on the experimental facilities.
