Nozzles are products used in many industrial fields. "Atomization" is one of the main effects of nozzles. Different nozzle types can produce different atomization effects, which will directly affect the coverage and efficiency of fluid injection. The next article will analyze the atomization effects of different types of nozzles.
The design and characteristics of the Nozzle will affect the size range of the droplets. Some nozzles can produce fine droplets, usually in the range of 10 microns to 50 microns. Such droplets are called fine mist. Other nozzles can produce larger droplets, usually in the range of 50 microns to 200 microns, which are called coarse fog.
The design of the nozzle and the spray pressure will also affect the uniformity of atomization. Some nozzles can produce evenly distributed droplets, ensuring that the liquid evenly covers the target surface. Uniform atomization is ideal for agricultural sprays, humid air and other Industrial applications are very important.
Different nozzles have different spray distances, and some nozzles can produce longer spray distances, which are suitable for applications that need to cover larger areas, such as fire extinguishing and firefighting. Other nozzles are suitable for spraying at close range, such as medical nebulizers.
Some nozzles have adjustable spray modes that can be adjusted as needed. Common spray modes include unidirectional spray, fan spray and annular spray. These flexible designs can be adjusted according to specific application needs.
The nozzle orifice of a Fan nozzle is fan-shaped and usually has a wide spray angle. It can produce uniform and finer mist particles and is suitable for scenes that require wide coverage of spray. Therefore, fan-shaped nozzles are often used for spraying, coating and wet spraying. It can provide high-quality coatings and uniform coverage in finely controlled areas such as chemical coatings.
The spray shape produced by a Full cone nozzle is conical, with a small spray angle. It is characterized by the fact that the sprayed liquid forms a solid cone-shaped mist mass, similar to the top of a cylinder with the top cut off. The spray droplets produced by the solid cone nozzle Large and evenly distributed, with high impact and coverage, this type of nozzle is typically used in applications requiring larger coverage areas and higher impact, such as cleaning, fire extinguishing, and sprinkler systems.
The spray shape produced by the Hollow cone nozzle is conical, but there is a hollow central area inside. The spray angle is usually larger and can reach a wide spray range. The droplets produced by the hollow cone nozzle are smaller and evenly distributed, forming a hollow Cone-shaped mist, this type of nozzle is typically used in applications that require fine droplets to cover a wide area, such as agricultural sprays, coatings, and humidified air.
The solid cone Spiral nozzle forms a spiral mist mass when injecting liquid with a large injection angle. Its characteristic is that the liquid mist droplets will rotate along a spiral shape while spraying. This rotation effect can increase the number of liquid mist droplets. The fog has a certain diffusion range and coverage area, and has a certain thickness. It can usually be used for agricultural spraying, air humidification and odor control.
