The common problems of fine mist sprayer heads are divided into three types of problems: physical damage, chemical corrosion, and other problems.

　　Physical damage:

　　Damage to the nozzle hole: Due to the long-term spraying of the nozzle, the nozzle hole is worn, and the nozzle hole is often damaged by removing the debris in the nozzle hole with hard objects. Generally, the nozzle needs to be replaced for the above problems.

　　Normal groove wears: Due to the destruction of the spray filter system, the blasting effect of fluid parameters, and the long time hitting the nozzle mouth, the groove is worn. For this phenomenon, the nozzle is generally replaced.

　　Corrosion/wear

　　The gradual consumption of nozzle material leads to the expansion or distortion of nozzle holes and internal liquid flow channels, which leads to increased flow, reduced pressure, irregular flow, and larger droplets. The nozzle may be corroded by the chemical components in the liquid so that the spray becomes uneven and the droplets are of different sizes.

　　Agglomeration/bonding

　　Due to the evaporation of liquid, the accumulation of materials in the nozzle mouth or outside measurement will occur. A dry solidified layer will remain on the nozzle mouth and block the nozzle mouth and the internal liquid flow channel, which will also affect the performance of the nozzle after bonding. Play, and will have serious consequences for some nozzles, especially air atomizing nozzles.
