How to improve the existing spray nozzle system ? Choose more corrosion-resistant materials. The corrosion rate of the solution to a particular nozzle material depends on the sprayed liquid and nozzle material. The corrosion performance, concentration and temperature of the sprayed liquid must be considered, as well as the corrosion resistance of the nozzle material to this chemical agent.
Use a lower spray pressure. Although not all occasions are possible, but reducing the use pressure is indeed a way to reduce nozzle wear, because the wear rate is related to the velocity of the liquid passing through the nozzle. Therefore, if a lower pressure is used, the velocity of the liquid passing through the nozzle is reduced, which can reduce the wear and corrosion of the nozzle.
Reduce the concentration of solid particles and corrosive chemicals. Although these methods can not be achieved in most applications, but reduce the number of solid particles in the liquid; changing the size or shape of the particles can reduce the wear of the nozzle. If there is a corrosion problem, depending on the nature of the chemical agent involved, different concentrations or temperatures can be used to reduce the activity of the solution.
Enhanced filtration: In many applications, nozzle damage or clogging is caused by solid particles in the sprayed liquid. In a spray system that uses circulating water, the water is easily contaminated by dirt and debris, which can cause nozzle blockage or wear. In order to reduce this kind of problem, it is recommended to choose a pipe filter or a nozzle built-in filter, and choose a good filter to filter out particles that may block the nozzle.
Prevent damage to the nozzle during the cleaning process. As part of nozzle maintenance and inspection procedures, nozzles must be cleaned regularly and carefully. The material of the cleaning tool must be softer than the material of the nozzle throat, otherwise the shape and size of the critical and expensive nozzle throat will be permanently damaged, causing the spray shape to change or the flow rate to increase.
It should be particularly emphasized that hard-bristled brushes, wooden brushes, plastic brushes can be used; metal brushes, knives or welding rod heads cannot be used. For cohesive blockages, it is recommended to use a non-corrosive cleaning solution to soften and dissolve the blockages.
Change the nozzle type or size. Occasionally, some nozzle problems will be caused by the nozzle selection. When intensified. If you have such problems, you can contact the nozzle manufacturer for solutions and suggestions.
