The nozzles have been used in all walks of life, and have been applied more and more widely. What are the reasons for their spray capability when they are used?
1、 Accidental damage: that is to say, if the use of the wrong way, or after the use of the nozzle can not be timely maintenance will lead to its accidental damage. Although most nozzles are usually concave, the offset structure of fan-shaped nozzles is easily damaged.
Two, erosion: if the liquid with high velocity is passing through the metal surface of the nozzle hole, it will corrode the nozzle hole at that time, resulting in the pressure drop of the spray equipment, so the spray state will also become irregular. The probability of nozzle erosion depends on the hardness of the liquid, the spray pressure, the type and amount of chemical materials used. In addition, the particles in the liquid will also make the nozzle seriously eroded.
3、 Temperature: if the nozzle works continuously at high temperature or abnormal temperature, the nozzle will be damaged due to material softening.
Four, obstruction: when some chemicals and impurities in some liquids are accumulated inside or outside the nozzle, the spray equipment will be blocked. This will also affect the spray shape of the nozzle, thus affecting the spray pressure.
5、 Corrosion: in the use of chemical materials to spray the workpiece, a large part of the chemical materials will cause a corrosion to the nozzle material.
These are the main reasons for nozzle failure. These are the places that we need to pay attention to in the process of using the nozzle. After we have a clear understanding of these reasons, we will have a clear reference on the use and maintenance of the nozzle.
