In different ph, viscosity, pressure environment.

The loss of nozzles of different materials is different. How to improve the corrosion resistance of the nozzles of the existing spray system to improve the service life of the nozzle of the spray system is a problem considered by many owners:

1, choose more corrosion resistant materials.

The rate at which a solution corrodes a particular nozzle material depends on the liquid sprayed and the nozzle material.
Consideration must be given to the corrosive properties, concentration, and temperature of the liquid sprayed, as well as to the corrosion resistance of the nozzle material to the chemical.

2, the use of lower spray pressure can achieve better performance of the nozzle.

Although not in all situations, reducing the pressure is one way to reduce nozzle wear, since the rate of wear is related to the speed of fluid passing through the nozzle.
Therefore, if a lower pressure is used, the velocity of the liquid through the nozzle is reduced, which can reduce the wear and corrosion of the nozzle.

3, Reduce the concentration of solid particles and corrosive chemicals.

Although these methods cannot be achieved in most applications, they reduce the number of solid particles in the liquid;
Changing the particle size or shape can reduce nozzle wear.
If corrosion is a problem, different concentrations or temperatures may be used to reduce the activity of the solution, depending on the nature of the chemical involved.

4,Strengthen filtration: in many applications, damage or blockage of the nozzle is caused by solid particles in the spray liquid.

In spray systems using circulating water, the water is easily contaminated with dirt and debris, which can cause nozzle blockage or wear.
To reduce such problems, it is recommended to choose pipe filters or in-nozzle filters, and to choose a good mesh to filter out particles that may clog the nozzle.

5, regular cleaning and maintenance of the nozzle, in order to prevent the damage of the nozzle in the cleaning process.

As part of the nozzle maintenance and inspection procedure, the nozzle must be cleaned regularly and carefully.
The material of the cleaning tool must be softer than that of the nozzle throat, otherwise the shape and size of the critical and most expensive nozzle throat will be permanently damaged, resulting in a change in spray shape or an increase in flow.

It should be emphasized that hard brush, wood brush and plastic brush can be used.
Do not use metal brushes, knives or electrode heads.
For cohesive clogging, it is recommended to use a non-corrosive cleaning fluid to soften and dissolve the clogging.
Change nozzle type or size.
Occasionally, nozzle problems can be exacerbated by improper nozzle selection.
If there is such a problem, you can contact the nozzle manufacturer for solutions and suggestions.
