An Engineer's Guide to Spray Technology

From Spraying Systems Co.
 

 

Because spray nozzles are designed to perform under many different spraying conditions, it is likely that there is more than one spray nozzle that would meet your general requirements. Following is a discussion of spray characteristics to help explain the criteria by which each candidate spray nozzle must be evaluated in order to achieve the most efficient spray performance in your individual application. More specific information may be obtained by contacting a sales engineer at your local sales office.

The hollow cone spray pattern is essentially a circular ring of liquid. This pattern is generally formed by use of an inlet tangential to a whirl chamber, or by an internal grooved vane immediately upstream from the orifice. The whirling liquid results in a hollow cone configuration as it leaves the orifice.
