How to clean and check nozzles

How to clean and check nozzlesCleaning and checking of nozzles is important for the optimum operation of a nozzle. A contaminated or damaged nozzle can cost you a lot of money, because it can lead to a waste of crop protection products. It is therefore advisable to check your nozzles every season. This ensures an even spray pattern and an even distribution of liquid within the crop. We give you a few tips for cleaning and checking your nozzles.

Cleaning nozzles

Dirt or residue can accumulate in a nozzle. This will clog the nozzle. You can remove this dirt with a soft brush or with compressed air. Never use a hard brush or any other hard object (such as a needle). Special care is required with a plastic nozzle, as this nozzle is more susceptible to damage than a nozzle made of stainless steel. For cleaning of nozzles, you can also use a cleaning agent or soda. Immerse the nozzle in this and then rinse it thoroughly with water to ensure proper removal.

Check nozzles for wear

Nozzles wear out during operation due to friction. This affects fluid distribution and the spray pattern. Therefore, check nozzles for wear. A nozzle should be replaced when the flow rate of the used nozzle is more than 15% higher than the flow rate of the (exact same) new nozzle. This can be measured by collecting the liquid sprayed with the old nozzle and the liquid sprayed with the new nozzle in a measuring cup and determining the difference.
