Selection method for ultrasonic air atomizing nozzles

Ultrasonic air atomizing nozzles, as a widely used type of nozzle in modern industry, have unique advantages and features.
This article will introduce the basic concept, application areas, selection points and maintenance of ultrasonic air atomizing nozzles, aiming to help readers understand and know ultrasonic air atomizing nozzles better, so as to choose the most suitable type of nozzles in industrial applications.

Ultrasonic Atomizing Nozzle

Basic concept

Utilizing the vibration energy of ultrasonic waves to convert liquid substances into micron-sized droplets, and mixing with high-speed flow of air to form a uniform mist, characterized by high efficiency, energy saving and environmental protection.
The ultrasonic air atomizing nozzle is mainly composed of two parts: the ultrasonic generator and the nozzle head. The ultrasonic generator is the device that produces the vibration energy, and the nozzle head is the place where the liquid substance and the high-speed flowing air are mixed.

Application areas

Widely used in industrial, agricultural, medical, environmental protection and other fields.
In the industrial field, ultrasonic air atomizing nozzles are widely used in painting, steel, metallurgy, electric power, chemical industry and other industries.
For example, efficient degreasing and descaling of metal surfaces, protection of electrical equipment from insulation, and efficient cooling of chemical reactors.
Additionally, in the field of agriculture, ultrasonic air atomizing nozzles are widely used in pesticide spraying, seed breeding and so on.

Key Points for Selection

1. Materials of the nozzle
One of the important factors need to be considered during the selection process. Different materials have different degrees of corrosion resistance, abrasion resistance, high temperature resistance and other characteristics, you need to choose the right material according to the actual application scenario.
Commonly used materials include stainless steel, aluminum alloy and plastic. Stainless steel has better corrosion and abrasion resistance which is suitable for most industrial application scenarios, while aluminum alloy and plastic have better lightness and easy to process which is suitable for some specific areas.

2. Atomization effect of the nozzle
One of the key factors in the selection process. A nozzle with good atomization effect can fully refine the liquid substance into micron-sized droplets and mix with other gases evenly to achieve better application results.
In general, the atomization effect of the nozzle is related to the vibration frequency and amplitude of the ultrasonic waves and the design of the nozzle head. The selection process needs to be based on the actual application scenarios to choose the appropriate atomization effect of the nozzle.

3. Types of liquids of the nozzle
One of the factors to be considered. Different nozzles are available for different types of liquids, including water, solvents, and paints. The proper type of nozzle for the applicable fluid needs to be selected according to the actual application scenario.

4. Flow and pressure of the nozzle
Different nozzles have different flow and pressure characteristics, and it is necessary to select the right nozzle with the right flow and pressure according to the actual applications. Generally, the flow rate and pressure of the nozzle are related to the internal structural design of the nozzle, as well as the frequency and amplitude of the ultrasonic vibration.
5. Installation and maintenance of the nozzle
During the selection process, it is necessary to choose nozzles that are easy to install and maintain in order to reduce the cost and improve the efficiency of use.
In general, nozzle designs with easy installation and maintenance usually have a good degree of modularity and easy-to-replace parts to facilitate installation and maintenance by the user.


When using ultrasonic air atomizing nozzles, you need to pay attention to the following points:
First, the seals and fasteners of the nozzle need to be checked regularly for looseness or wear, and if any problems are found, they should be replaced in time.
Second, check the fluid inside the nozzle periodically to make sure it is flowing smoothly.
