The corrosion resistance corrosion test must be carried out by the salt spray test box, which leads to corrosion resistance. The most important thing is that the experimental aqueous solution is made according to the nozzle sprayer under the compression of air that must work at the pressure. The quality of the sprinkler immediately affects the success and failure of the experiment. In the production of the sprinkler, there are always strict controls on the diameter of the sprinkler and the angle of bending, so as to ensure that it can meet the required corrosion resistance. In specific applications, the sprinkler head is often blocked and cracked, which affects the normal development of the experiment. Therefore, we will introduce the following tips in detail for the sprinkler head for stronger maintenance of the salt spray test box.

1. Pure water or double-distilled water must be used to reduce the residue in the water and reduce the probability of clogging the sprinkler.
2. Install an oil and gas separator to prevent the water vapor and oil in the gas from being brought together when the air is compressed, so that the oil stains adhere to the inner wall of the nozzle. Because the nozzle has a small diameter, both the residue in the water and the adhered oil stains affect the formation of salt spray.
3. To prevent collision, after installing the application nozzle or blocking the nozzle, you must pay attention to it when you carry out the transmission, and do not need to use excessive force to damage the nozzle.
4. It is not necessary to set the working pressure of the sprayer too large. Generally, the working pressure is between 0.07mp and 0.17mp. If the working pressure is too large, the spray head may crack.
The above are some daily precautions for nozzles. If the spray volume is too large / too small or not sprayed during the salt spray test, you should check whether the nozzles are normal. If the nozzle aperture is too large, it should be replaced. If it is blocked, use a thin iron wire to pass it through.
