The salt spray test chamber mainly detects the corrosion resistance of the product by the action of salt spray, and the salt spray is formed by spraying the test solution under a certain pressure of compressed air through the nozzle. Therefore, the quality of a nozzle is also a direct factor in the success or failure of the test, and the nozzle design has very strict control on the bending angle and aperture of the nozzle to ensure the standard of salt spray.
In addition, the phenomenon of cracking and clogging of the nozzle will have certain influence on the normal operation of the test in daily operation. Here are a few tips for maintenance the nozzles of the test chamber:
1) For the installation of the oil-water separator, it should be avoided to bring the water vapor and oil in the air together when the air is compressed. At the same time, it is brought into the wall of the nozzle, and the pore diameter of the nozzle is relatively small, so whether the impurities in the water or the attached oil will affect the salt spray.
2) The spray pressure of the nozzle of the salt spray test chamber should not be set too large. Normally, it should be between 0.07 mp and 0.17 mp. If the pressure is too high, the nozzle may be broken.
3) Avoid impact. When installing or using the nozzle or clogging the nozzle, pay attention to the principle of handling it gently. Excessive force may cause damage to the nozzle.
4) In the salt spray test, distilled water or deionized water must be used to reduce impurities in the water, that is, to reduce the probability of nozzle clogging.
