Ultrasonic nozzles operate by converting high-frequency sound waves into mechanical energy, which is transmitted to the liquid to generate standing waves. As the liquid exits the nozzle's atomizing surface, it breaks apart into a fine mist of uniform, micron-sized droplets.

The principle of ultrasonic spraying
Ultrasonic nozzles operate by converting high-frequency sound waves into mechanical energy, which is transmitted to the liquid to generate standing waves. As the liquid exits the nozzle's atomizing surface, it breaks apart into a fine mist of uniform, micron-sized droplets.
Unlike pressure nozzles, ultrasonic nozzles do not rely on high pressure to force liquid through a small orifice to create a spray. Instead, the liquid is fed through the center of the nozzle — which features a relatively large orifice — without pressure, and is atomized due to the ultrasonic vibrations within the nozzle.
Each ultrasonic nozzle operates at a specific resonant frequency, which determines the median droplet size. For example, a 60 kHz nozzle produces a median droplet size of 20 microns (when spraying water). The higher the frequency, the smaller the median droplet size.
Introduction of the ultrasonic spray coating system
The JH-TWG05 ultrasonic spray coating system is a fully enclosed, programmable, three-axis robotic sprayer. This equipment can be equipped with various types of ultrasonic nozzles, making it ideal for a wide range of spraying applications. Users can select the appropriate ultrasonic nozzle based on their specific application, customizing the spray trajectory and area. The spray width can range from 1 to 80 mm and is easily adjustable. A precision injection pump can accurately supply various liquids with a wide flow range. In terms of production capacity, this equipment is more suitable for laboratory research and development and small-scale production.
