WATER SPRAY NOZZLE AND METHOD OF OPTIMIZATION OF WORKING PARAMETERS OF WATER SPRAY NOZZLE

摘要

The nozzle contains at least one swirl chamber (8), which is cylindrical in shape and situated between the spin chamber (7) and the outlet opening (4), and the diameter (d1) of the first swirl chamber (8), connected with a spin chamber (7), is less than the diameter (D) of the spin chamber (7). When the number of swirl chambers (8) is greater than one, the diameter (d2) of each following swirl chamber (9) is less than that of the preceding swirl chamber (8). The nozzle has an outlet chamber (10), which sides have one or more air inlet. The method of optimization of the working parameters of the water spray nozzle consists in that the stream drawn from the water supply conduit is supplied into the spin chamber (7) entirely or at least 95% through the spin channels (6, 6′) and the stream is put through one or more successive cylindrical swirl chamber(s) (8, 9) having decreasing diameters (d2d1), and then it is directed to the outlet opening (4). Next the stream is put through an injector device in the form of an outlet chamber (10) in the nozzle body (1, 13), or in another external unit, which chamber (10) has in its walls one or more air inlet channels.
