What Is an Air Blow Nozzle?
An Air Blow Nozzle is a nozzle that uses compressed air or gas to blow air at high speed.
By blowing air intensively, it can remove dirt and dust from the surface of an object or dry it. Air Blow Nozzles consume air efficiently and can sometimes be expected to save energy for compressors and other equipment.
Uses of Air Blow Nozzles
Air Blow Nozzles are widely used in industrial applications. They are used in a wide range of fields from the automotive industry to the food industry.
1. Maintenance
When used for maintenance and cleaning, air blow nozzles remove dust and dirt from machine and product surfaces. It is sometimes used to remove dust from human bodies.
2. Cooling of Objects
Air may be used to cool objects. This is installed in lines that require rapid cooling, such as resin processing and molding lines and cast product transfer lines. It is also used to repel foreign substances by air pressure.
3. Automotive Industry
Air Blow Nozzles are used in the automotive industry to dry painted surfaces quickly. Air Blow Nozzles are used in the food processing industry to dry fruits and vegetables. They are also used to dry banknotes and clothing.
Principle of Air Blow Nozzles
Air Blow Nozzles are typically designed so that compressed air or gas flows from a narrow tube into which it is injected to a wide opening. This narrow tube section is called the nozzle throat, where the compressed air is accelerated to a higher velocity. The tip of the nozzle that extends from the nozzle throat is called the nozzle diffuser, where the air is slowed down and the pressure is reduced.
This change in velocity causes the air blown out of the Air Blow Nozzle to flow at a high velocity. Air Blow Nozzles are used for the above applications by utilizing this air flow.
Some Air Blow Nozzles can be adjusted to blow air in any direction. By adjusting the moving parts, the flow of air blown out of the Air Blow Nozzle can be adjusted.
How to Select an Air Blow Nozzle
When selecting an Air Blow Nozzle, it is important to pay attention to the following points:
1. Shape
The shape of the Air Blow Nozzle should be selected according to its intended use. Thin tubular products can enter and operate in narrow crevices. On the other hand, wide fan-shaped products can cover large areas.
2. Outlet Size
Vent size should be selected according to the air pressure and blowing volume to be used. Generally, the outlet inner diameter should be selected so that it is proportional to the air pressure value to be used. Air Blow Nozzle manufacturers may provide a diagram showing the relationship between the inside diameter of the outlet and the air pressure.
In some sectors, such as electronics manufacturers and the automotive industry, the air outlet size may be very small.
3. Air Pressure
Selection should be based on the air pressure to be used. Air Blow Nozzles can quickly deteriorate depending on the frequency of use and the environment in which they are used.
Using an Air Blow Nozzle designed for the appropriate air pressure will extend the life of the Air Blow Nozzle itself. It is also important to choose Air Blow Nozzles made of durable materials and designs.
4. Piping Connection
The connection port of the Air Blow Nozzle to the air source piping must also be selected. The connection port should be selected according to the diameter of the piping. It is also necessary to select a fitting and connection method according to the air source pressure.
Ease of connection must also be considered. Selecting a connection port that can be easily connected, such as a one-touch fitting, can reduce work time.
5. Options
Air Blow Nozzles blow air at high speed, which can cause injury if used improperly. Safety can be ensured by selecting an Air Blow Nozzle equipped with an appropriate safety device.
There are also Air Blow Nozzles that can control the amount of air, and whether it is sprayed or stopped. Products with the necessary options should be selected.
