The structure design of the salt spray test chamber is advanced and reasonable, which can adapt to long-term, stable, safe, and reliable testing needs. And it is easy to use, operate, and maintain, with a long service life, beautiful appearance, and a good user interface, making user operation and monitoring simpler and more intuitive.
Today, the editor will take you to understand the structure and function of the salt spray test chamber:
1. Both the inner and outer shells need to be made of imported PVC plastic sheets, which are softened at high temperatures and then cooled through a special mold to form a shape. The seams between the sheets are cut into a 90 degree right angle, and then filled with plastic welding wire melted by a high-temperature welding gun. After cooling, the welds are more firm, and the seams of the entire box are smooth and flat, with a compact box structure and a shiny appearance.
2. The spray mode of this equipment is to place the embedded glass nozzle in a round plastic pipe, guide the spray through the tower pipe, and then disperse it to the inside of the laboratory through the cone disperser.
3. Salt solution replenishment tank: adopts a hidden structure with a water level perspective window attached. Easy to clean, convenient for observing solution water level.
4. Spray system: adopt the air flow spray method and the siphon principle to atomize the absorbed salt solution through the nozzle. The atomization particle size is uniform, which can ensure the continuity and stability of the test. The non crystallization nozzle is used, and the baffle type spray device is evenly and freely dropped into the salt spray test chamber after being diffused by the baffle, so that the salt spray sedimentation reaches the specified value. The brine before spray is injected into the preheating tank through the brine storage tank, preheated, and then introduced into the nozzle. Make the temperature fluctuation of the constant temperature studio smaller. Salt spray settling amount: The salt spray settling amount can be controlled by adjusting the nozzle pressure and the height of the baffle cone, so as to achieve a salt spray settling amount of 1-2ml/cm2 · h. The saturated air tank adopts the Henry's law to provide clean and humid air that is consistent with the working temperature inside the box through heating and warming.
5. The temperature inside the salt spray test chamber of this series adopts bottom water heating method, which makes the temperature inside the chamber more uniform and stable. The heating element adopts Qin heating tube, which is salt resistant, corrosion-resistant, and has a long service life.
6. Saturation bucket: made of SUS304 high-grade stainless steel plate, with good high temperature and high pressure resistance.
7. The box cover is made of PVC transparent board, and the box cover switch is convenient and easy to operate. The top cover of the box adopts a water sealed structure to ensure that salt spray does not overflow.
8. Laboratory sample rack: V-shaped bracket and 0-type suspension bracket are both made of stainless steel tube wrapped with heat shrinkable PVC film, which has corrosion resistance and load-bearing capacity. They can place a large number of specimens and freely choose 15 ° or 30 ° to place the test plates. If the purchaser requires a special sample rack, please specify it when placing an order.
9. Using a non crystalline nozzle, the mist is atomized through a baffle, and the mist spreads evenly and settles freely in the salt solution tank of the salt spray test chamber. A detachable filter is installed at the front end of the suction tube.
10. The box cover adopts an angle of 110 °~120 ° to ensure that condensed water does not drip onto the specimen, and the box body is equipped with pressure balance holes and condensate discharge holes
11. The automatic water addition system is adopted, which can automatically replenish the water level when the water level is insufficient, and the test is not interrupted.
Equipped with dual over temperature protection and low water level warning to ensure safe use.
12. The saturated air tank adopts the Henry's law to heat and provide the required humidity for the salt spray test chamber.
