The different structure of the sprayer will lead to the difference in the processing efficiency and the service life of the sprayer. The reasonable sprayer structure enables the abrasive to obtain high speed, which is the necessary condition for improving the processing efficiency and reducing the cost. From the advent of the sprayer to a long period of time afterwards, the cylindrical shape is adopted. Sprayer structure. So far, the sprayer structures developed at home and abroad are in various forms. The fuel sprayer is equipped with electromagnetic coils, iron cores and needle valves integrated with the iron core. Commonly used sprayer structure types and characteristics.
1. Structure of cylindrical straight hole sprayer
Schematic diagram of the structure of the cylindrical straight hole sprayer. It has both the functions of a spray gun and a sprayer. It has a simple structure and can be directly replaced by seamless steel pipes. It can also be obtained by drilling in the material. Dealing with less demanding occasions
2. Conical sprayer structure
This sprayer structure has a cone-shaped inlet with a diversion function and a straight section that serves as a clustering function. It is relatively easy for the abrasive to enter the sprayer, and the distribution of the abrasive on the cross section of the sprayer is more even than that of the cylindrical sprayer.
3. Special sprayer
Double-outlet special sandblasting nozzle, complex structure, generally used in special occasions, such as the sandblasting treatment of the inner wall of the pipeline
4. Combined sprayer structure
Design materials with different properties at the entrance, exit and middle of the sprayer, and assemble each part of the material into a sprayer by mechanical combination. The combined sprayer is designed with high hardness ceramic or other resistant materials at the entrance and exit of the sprayer. Abrasive material, the middle section of the sprayer can be designed with high toughness metal or other materials. The combined sprayer can meet the different requirements of the sprayer inlet, outlet and middle parts of the erosion resistance and wear resistance to a certain extent. Ability to wear, but compared with a monolithic sprayer, two or more materials need to be prepared, and assembly and other related processes are added.
