The most critical spray system for the salt spray test chamber consists of a compressed air supply, a brine tank, and multiple sprayers. The requirements for the various components in the spray system are also in equal proximity. The material of the nebulizer from which the spray is made should not react with the salt solution, and the nebulizer should be selected to provide a means for producing fine, moist, dense mist particles.
Salt spray test chamber internal equipment spray system:
1. Adopt tower sprayer (tower height adjustable), guide salt spray, fine mist particles, natural settlement, no salt crystallizing of nozzle, adjustable settlement.
2. The sprayed gas will be regulated by two-stage voltage regulation, and at the same time, the oil is filtered and the gas is humidified and preheated at the same time.
3. The atomized brine storage will be built-in concealed and have a large storage capacity, and the brine is recharged with a preheating function.
4. The quartz brine filter element is equipped before the atomization of the salt water to avoid the blockage of the nozzle impurities and terminate the test.
5. Air pressure: 0.2 ~ 0.4Mpa, spray pressure: 0.05 ~ 0.17Mpa.
6. Spray method: continuous, intermittent spray can be adjusted at will.
7. All pipes in the salt spray test chamber are made of thickened fluorosilicone rubber tubes.
The spray system uses a tower spray and the height can be adjusted as needed. After use in the spray device, the compressed air that should enter the sprayer must be cleaned first. Impurities such as oil and dust generated inside. In the case where it is necessary to adjust the spray pressure, it should be adjusted so that the salt spray settlement amount satisfies 1 to 2 ml / 80 cm 2 · h. In the case of salt spray test chambers, the spray device is one of the key points. Whether the salt spray test chamber can be sprayed smoothly should be adjusted according to the standard before use and cleaned after use.
