Salt spray test chamber is mainly through the equipment to produce salt spray effect of the product corrosion resistance of the test, and the production of salt spray depends on the test solution in a certain pressure of compressed air through the nozzle and spray formed. Therefore, the quality of a nozzle is also a direct result of the success or failure of the test, and in the design of the nozzle for the nozzle bending angle and aperture and so have a very strict control, so as to ensure the standard salt spray. In addition, in the daily use, the nozzle of the rupture and congestion and other phenomena will be the normal operation of the test will have a certain impact, for this situation on the sea forest equipment Co., Ltd. here, a few maintenance of small The secret to let everyone better protect the nozzle of the test chamber.
1) For the installation of oil-water separator, air pressure should be avoided when the air vapor and oil into the same. While being brought into the oil can be attached to the nozzle wall, and because the nozzle aperture is relatively small, so whether the impurities in the water or attached to the oil will affect the production of salt spray.
2) Salt spray test chamber nozzle spray pressure should not be set too large, usually should be 0.07mp to 0.17mp range, the pressure is too large is likely to cause the nozzle rupture situation.
3) should avoid the impact of the installation of the use of nozzles or plug the nozzle after it is necessary to clear the light when the principle of light, excessive force will lead to damage to the nozzle situation.
4) in the salt spray test, you must use distilled water or deionized water, reduce water impurities, that is, to reduce the chances of nozzle clogging.
