This rapid change in flow rate and pressure causes the fogging atomize nozzles to form a high-speed jet of liquid at the outlet of the diffusion section. When the high-speed jet leaves the nozzle, it will be subjected to the resistance of the surrounding air, resulting in violent turbulence and shear force. The action of these forces causes the jet to be rapidly broken into a large number of tiny droplets, forming the spray effect we see.
In addition to the design of the fogging atomize nozzles, the spray effect of the sprayer is also affected by other factors. For example, the physical properties of the liquid (such as viscosity, surface tension, etc.), the working pressure of the sprayer, the distance between the nozzle and the target, and the spray speed will have an impact on the spray effect.
The nozzle of the fogging atomize is to spray the liquid by compressed air. The internal structure of the nozzle is composed of the nozzle, the vortex chamber, the studio and the trigger needle, etc. The specific implementation process is as follows:
1. The liquid is transported to the vortex chamber and nozzle through the pipeline. When encountering the high-speed rotating vortex chamber, the liquid will produce a strong centrifugal effect and form small droplets.
2. The droplets enter the studio further, are ejected under air pressure, and form a uniform mist spray.
3. The trigger needle of the nozzle is responsible for controlling the release of compressed air and the closure of the nozzle, so as to achieve the ejection effect.
