During the experiment, the indoor test conditions can be clearly observed from the outside without affecting the test results. And the lid is designed toThe optimal top angle is 120 degrees to prevent condensation generated during the test from dripping onto the sample and affecting the test results. The box cover and body are sealed with water to prevent salt spray from overflowing, which may affect the test results and corrode other equipment in the room, and may even cause harm to the test operators.

3.Measuring cylinder：Collect the amount of spray for each test 50mlFor the highest scale.

4Saturated air tank:Placed at the bottom of the control box,2.0mmSUS304 # stainless steelmaterialIt can filter, warm and humidify the purified air to reach the saturation temperature and humidity and then send it to the nozzle for sprayThe saturator has an automatic water replenishment function.

5. Regulating valve:Manually adjust the air inlet pressure and spray pressure. The intake pressure is controlled within 0.3mPa； Spray pressure control 0.07-0.17mPa. (The above pressure has been adjusted before leaving the factory. Generally, users do not need to adjust it again.).

6Pressure gauge:The pressure displayed by the pointer of the pressure gauge is the pressure when the air saturated air bucket conveys the nozzle spray.

7Mist exhaust pipe:diameter 50, the pressure caused by spray and the excess water in the salt spray test chamber also overflow.

8. spray device:The tower spray contains a glass nozzle. The spray is guided by the tower tube and then dispersed through the cone. After being evenly dispersed, it spreads to the whole laboratory.

9. Adjustment of spray volume:Adjust the conical disperser on the spray tower to increase the spray volume, and lower it to reduce the spray volume.

10. Collector:The fine mist sprayed by the nozzle settles in a free fall manner and is embedded on one or several surfacesaccumulate

80cm²The funnel cup collects salt spray, which condenses into water and flows through a conduit to the measuring cylinder outside the box.

11. Heated water tank: The water tank is attached to the bottom of the laboratory and is used to hold water, heat it up, and maintain a stable temperature in the laboratory.

12. Storage rack: made of plastic steel, with a single load-bearing capacity of no more than 2kg. If scattered, it can withstand a weight of up to 10kg. There are two rows of circular holes on both sides of the storage rack, which are used to place storage rods at a vertical angle of 20 degrees and 30 degrees. The bottom plate is laid with a grid plate, and heavy samples are placed on the bottom plate, with a sample weight of ≤ 300 kg.

13. Nozzle: The nozzle is made of tempered glass, which can adjust the size of spray volume and spray angle Precision crystal glass nozzle (PYREX) for 4000 hours to ensure no crystal blockage.

14. Circuit system: The circuit control board and other components are fixed in a position that is easy to inspect and maintain. The door lock opening edge cover door is used, which is not only beautiful but also easy to maintain. The electrical box is independent, avoiding any salt spray from corroding the core control system and electronic components, greatly extending the service life of the entire machine.
