What are the types of ceramic nozzles ?
Ceramic nozzles have been continuously improved since they were introduced into China in the 1990s. Mainly improved from two aspects of shape and material:
Shape: The shape of the ceramic nozzle has developed from the early spiral type, large capacity, and two-wheel spray to spiral type, vortex type, and small volume type.
Materials: Materials have gradually developed from oxide ceramics to nitride ceramics and carbide ceramics.
The ceramic nozzles we refer to in China refer to the following types:
1. Oxide ceramic nozzles (see alumina and zirconia materials)
Nitride Ceramic Nozzles (See Silicon Nitride Bonded Silicon Carbide Materials)
Silicon carbide ceramic nozzles (see silicon carbide, boron carbide materials)
The performance of oxide ceramic nozzles is lower than that of silicon nitride nozzles and silicon carbide nozzles, so they are gradually eliminated.
What are the mainstream products in the ceramic nozzle market? Let's analyze it together.
1. Nitrogen connection combined with silicon carbide nozzle (white)
The advantages are high hardness and strong wear resistance, both advantages and disadvantages, the material is too strong to make spiral nozzles.
Silicon carbide nozzle (black, green)
The advantages of ceramic nozzles are high hardness and good ductility, which can be used to make spiral nozzles and swirl nozzles. Of course, there are advantages and disadvantages, and the wear resistance is relatively poor.
The ceramic nozzle is a precision product combining ceramic parts and stainless steel parts, and each part is finished. So we should pay attention to these when using.
The main part of the ceramic nozzle is called the spray, and the middle part of the spray has a slope of 45 degrees, and there are 8 equally divided water inlet holes on the slope. Because there are 8 small holes, it is relatively weak and easy to deform. Therefore, do not use excessive force when installing the nozzle. According to the structural characteristics of the ceramic nozzle, it is recommended to design multi-point contact and use a special wrench for the force-applying nozzle. In this way, when the ceramic nozzle is assembled , it will not be easily deformed, and the use accuracy of the nozzle can be guaranteed.
The nozzle is easy to operate during use, such as irrigation of crops, the whole crop can be sprayed in water. In the chemical industry, it can also make the whole work more quality. However, damage may occur during use, and ceramic nozzles usually fail under the following conditions, specifically what? Let's analyze it together.
1. When corroded by foreign products, such as impurities in liquids.
2. Improper use or improper maintenance will lead to failure.
3. If it is clogged, the full spray and pressure to the nozzle will produce a spray effect.
4. If the temperature is higher or lower than the standard temperature of the nozzle, there will be problems, which will affect the whole work.
