The Principle Of Atomizing Effect Of Trigger Spray A
Spray nozzles can be classified according to the energy input that causes atomization,
breaking the liquid into droplets. Many single fluid nozzle configurations are used depending on desired atomization characteristics.
The spray nozzles used in these locations are called “single jet nozzles” and are sprayed by liquid pressure alone instead of using air.
Compressed air from such nozzles can be used to spray even a very fine jet over many meters.
Single fluid or hydraulic spray nozzles are more energy efficient in surface treatment than most other types.
Single fluid or hydraulic spray nozzles use the kinetic energy imparted to the liquid to separate it into droplets.
Hydraulic nozzles rely entirely on the internal energy of the liquid being sprayed to break it up into droplets and form the spray pattern.
Air nozzles, on the other hand, apply compressed air to the liquid being sprayed to break it up and form a pattern.
If the atomizing air pressure decreases (about 0.02-0.05 MPa), the atomizing air pressure forms a jet with irregularly shaped droplets the size of a raindrop.
When an aerodynamic force, i.e. liquid flowing out of an orifice in contact with ambient air, comes into play during atomization,
a pressure change occurs which causes changes in the pressure dispersion around the droplet. When a liquid passes through a small orifice under pressure,
the surface tension of the liquid causes it to flow out of the orifice in a jet or sheet, which then comes into contact with the surrounding air and breaks up into small droplets.

The process of breaking up the supplied liquid into droplets or small splashes under the action of surface tension along with internal or external forces is called atomization.
There are factors influencing the process and its result of the fine atomization of liquid droplets. Atomization occurs when liquid is forced through an orifice to create a spray.
Atomization can be adjusted by increasing or decreasing the pressure of this air (atomizing air).
The special design of the internal structure of the air mist nozzle allows the liquid and gas to mix evenly,
creating a micro-droplet-sized aerosol or large-droplet spray.
The fine atomization droplets generated by the air atomizer can have an excellent environmental humidifying effect.
Adjustable air atomizing nozzles can adjust the fluid flow without changing the air pressure
and fluid pressure in the environment to produce the same atomization as required.
The nozzle may need to be replaced, which can affect spray volume and system pressure.
Be aware of speed changes as spray system pressure may be required to exceed nozzle recommended operating ranges, resulting in excessive drift.
Drift potential can be reduced by increasing droplet size, using large-bore nozzles,
and/or lower spray pressure with higher flow nozzles.
Low pressure reduces the spray rate and the material being sprayed may not spray across the entire width unless the tips are designed to operate at lower pressures.
Oils form as droplets smaller than water when sprayed with the same hydraulic nozzle and spray pressure.
