THE DIMENSIONAL CHANGE OF FAN NOZZLE TIP ORIFICES IN CONSEQUENCE OF WEAR PROCESS

ABSTRACT
The dimensions of fan spray nozzle tips have been determined before and after a wear test of fifty-hour by a measuring microscope. The design, nominal capacity, and the material have influenced the dimensional change of the tips through wear. The percentage increase of the characteristic dimensions, the quotients of minor/major axis and the area of nozzle tip orifices were determined. The regression diagrams and equations of the dimensional changes vs. nominal capacity were worked out. It has been found that the percentage of dimensional changes of Standard Flat Spray Tip types is less than the dimensional changes of Extended Range Flat Spray Tip types.
Key words: dimensional change, nozzle tips, sprayer, wear test.
