Title : Impact of speed and type of a sprayer on the degree of covering horizontal and vertical sprayed surfaces
Key words : degree of covering, spraying speed, sprayer type
Summary :

The paper presents the results of research on the degree of covering the sprayed facilities with the use of four types of sprayers. The measurements were carried out at four work speeds of an aggregate, constant pressure of liquid and a constant dose of liquid. The tests were carried out in the laboratory conditions, for which a carrier of sprayers was used. The research was carried out on three artificial plants, on which water sensitive papers were mounted. Facilities determined as: upper levels (Apog), lower levels (Apod), vertical approach (Anj) and vertical depart (Aoj) formed probes. In order to determine the degree of covering, the papers were subjected to computer image analysis. The results were subjected to multi-factor analysis of variance, which proved that the applied sprayer and the speed of aggregate significantly influenced the degree of covering vertical facilities. In case of upper horizontal facilities, no significant impact of the working speed was reported. The increase of the spraying speed caused the increase of the degree of covering the approach surfaces. The opposite relation was reported for departure surfaces. No noticeable coverage with a sprayed liquid was noticed on horizontal objects.
