There are four basic conditions for the selection of atomizing nozzles, which are:
Medium
Density, viscosity, surface tension (determines the actual effect of the spray), temperature, and pH value (determines the material of the nozzle).
Effectiveness
Injection pressure, determines the result and flow rate of the nozzle.
Impact force, determines the cleaning effect of the spray.
Backlash force, determines the type of nozzle and destructive force.
System
The power and head of the pump which determines the rated pressure.
The total flow of the system which determines the rated flow.
The pressure at which the piping system is designed which determines the actual working pressure of the nozzle.
Spraying
Angle, which determines the number and spacing of cross-arrangements.
Shape, which determines the flow distribution characteristics.
Particle size, which determines the actual effect of atomization.
Flow rate, which determines the orifice size and shape of the nozzle.
These four selection conditions for atomizing nozzles are also applicable to other types of nozzles, which you can take into account when purchasing nozzles.
