Common causes that affect nozzle spray
The nozzle needs to be repaired, regularly inspected, cleaned and even replaced in order to ensure the quality of the final product and maintain the economic benefits of the production process. The method and frequency of maintenance procedures depend on the application. The maintenance plan can be arranged according to the purpose, liquid and nozzle material.
There are seven common causes that affect nozzle spray problems:
1. Corrosion and wear: The material on the surface of the nozzle nozzle and the internal flow channel gradually becomes larger or deformed, which in turn affects the flow rate, pressure and spray shape.
2. Corrosion: The spray liquid or the chemical action of the environment causes corrosion and damages the nozzle material.
3. Blockage: Dirt or other impurities in the liquid block the nozzle mouth, thus limiting the flow rate of the nozzle and disturbing the spray shape and its uniformity.
4. Adhesion: Splashing, mist or chemical accumulation on the material inside or outside the edge of the nozzle caused by the evaporation of liquid can leave a dry solidified layer and block the nozzle opening or internal flow channel.
5. Temperature damage: Overheating will have a certain damage effect on nozzle materials designed for non-high temperature applications.
6. Improper installation: Washers that deviate from the axis, over tightening or other changes in position can have adverse effects.
7. Accidental damage: During installation and cleaning, the nozzle may be accidentally damaged due to the use of incorrect tools.
