Spray nozzles & systems
What surface should the spray cover? How should the nozzle be positioned?
The position of the nozzle over the target (D) and the area to be covered by the spray (B) are important to know in order to choose the right spray angle (A). The spray angle is measured near the nozzle orifice and the droplets are immediately affected by external forces such as gravity, air and gas flow.
Four parameters are used to define spray coverage
Spray angle (A)
The spray angle is measured near the orifice of the nozzle. Since droplets are immediately affected by external factors (gravity, air and gas flow), this measurement is only useful when calculating spray coverage near the nozzle.
To calculate spray coverage at greater distances, we provide spray trajectory diagrams if needed.
Actual spray coverage (B)
Actual spray coverage at a specified distance (D) from the nozzle.
Effective spray angle (C)
The angle calculated from the actual coverage (B) at a distance (D).
Theoretical spray coverage (E)
The coverage at distance (D) if the spray moved in a straight line from the nozzle orifice.
|Distance (D) in mm|
|Spray angle (A)||50||100||150||200||300||400||600||800||1000|
Optimising the spray coverage
When we design a spray system that requires coverage over a large cross-sectional area, the spray is optimised to provide the most even coverage possible over the entire area.
