1. Corrosion and wear: the material on the surface of nozzle nozzle and internal flow channel gradually becomes larger or deformed, which will affect the shape, flow and pressure of nozzle.
2. High temperature: overheating will damage nozzle materials for non high temperature purposes.
3. Accidental damage: during installation and cleaning, the nozzle may be accidentally damaged due to the use of incorrect tools or gravity beating.
4. blockage: dirt or other impurities in the liquid block the nozzle orifice, thus limiting the flow of the nozzle and interfering with the spray shape and its uniformity.
5, corrosion: spray or other chemical substances and the role of the environment to cause corrosion.
6. Changing the installation or position: incorrect installation: excessive tightening or other problems of changing the position can cause damage.
7. Sticking and blocking: splashing, fog or chemical accumulation on the materials inside or outside the nozzle edge caused by liquid evaporation can leave a dry solidification layer and block the relevant channels of the nozzle.
