How to handle the spray failure of the salt spray corrosion tester?

If the salt spray corrosion tester has a spray failure, it may be that the nozzle is blocked. How should we deal with the blockage?
Salt spray test chamber adapted to the surface treatment of various materials, electroplating, organic and inorganic.
1, in order to quickly deal with the blockage of the nozzle of the salt spray corrosion tester, we must first find the cause of the blockage. It may be that the equipment has not been used for a long time, and the nozzle has not been cleaned daily, resulting in the formation of crystalline substances, chemical substances, etc. on it, and a coupling effect occurs at the same time (two or more chemicals and crystalline substances on the nozzle are combined. phenomenon), then the nozzle holes and channels will be blocked; it is also possible that the nozzle is often used, the liquid filtration system is damaged, and the fluid has a "sandblasting" damage effect; in addition, the nozzle is hit and causes gaps or fragments. etc.;

2, it can be seen by checking the pressure index of the equipment. If the pressure index is normal, it means that there is a problem with the nozzle and the pipeline. By checking whether the salt water is circulating, it can be seen that the nozzle and the pipeline are the problem. If it is an impurity To block the nozzle, you need to use the Q gun to blow out the impurities from the head of the nozzle, never from the silicone tube; if there is no impurities, after the equipment spray switch is turned on, when the air comes out from the curved glass tube of the nozzle , and then re-adjust the position of the nozzle. If the nozzle is blocked due to damage, it needs to be replaced in time.

To avoid impurity clogging of the nozzle of the salt spray corrosion tester, the water in the test chamber must be filtered or softened water (usually distilled water or deionized water, etc.), which can reduce the probability of clogging, and the aperture of the equipment nozzle should not be too large If it is small, it is also prone to blockage; install an oil-water separation device to avoid the water, oil, etc. being brought in together when the air is compressed, so that the oil stains adhere to the wall of the nozzle to reduce blockage. Daily attention should be paid to protection, and try to avoid damage caused by nozzle collision.
