The cause of the failure of the paint gun nozzle

the cause of the failure of the paint gun nozzle
a. erosion. When a liquid with high flow rate passes through the metal surface at the nozzle hole, it erodes the nozzle hole, causing the nozzle pressure to decrease and the spray state to become irregular. The rate of nozzle erosion depends on the hardness of the liquid, the type of chemical material used in the spray pressure and its use, and the particulate impurities in the liquid can also cause the nozzle to be severely eroded

b. Accidental damage. Incorrect use and failure to carry out timely maintenance are the main causes of accidental damage to nozzles. Although nozzles are usually designed to be indented, the offset structure of fan nozzles is vulnerable.
c. Corrosion. These chemicals can also cause corrosion of nozzle materials when spraying work parts with chemical materials.
d. Blocking. The accumulation of chemical materials and impurities on the inside or outside edges of the nozzle can cause blockage of the nozzle, which affects the spray shape of the nozzle and thus the spray pressure.
e.temperature. Nozzles that work at high or abnormal temperatures for long periods of time can cause damage to the nozzles due to material softening.
