The salt spray test chamber can test the corrosion resistance of certain commodities, and can test the processing quality of products similar to the protective layer. This test chamber is suitable for parts, electronic components, and metal composite materials. Corrosion resistance and corrosion testing of industrial products. The next thing we need to understand is, what is the cause of the failure of the sprayer in the salt spray test chamber?

1. Check the switching power supply, check whether the water level of the test box and the water level of the saturation bucket are normal. You can press and hold the reset switch of the time controller to adjust whether the time controller can be set. And ask about the working pressure of the left and right barometers. If the air compressor is not broken, try to adjust the pressure reducing valve of the box to see if there is any reaction force. The working pressure of the rear barometer is 2kg, and the working pressure of the front barometer is 1kg, which shows that the barometer is very good.

2. If the rear air pressure gauge has working pressure but the front air pressure gauge has no pressure, the pressure regulating valve may be damaged before troubleshooting. Jets controlled by relays can also be damaged.

3. We can pull out the nozzle to see if it is blocked. Cleaning methods such as nozzle clogging can be used to clean the bronchus with an air compressor or pull out the bronchus with a soft feather duster.

4. The rubber hose is easy to become brittle. The cleaning method can be to connect the stored brine to the side of the salt spray test chamber with a plastic hose, and glue the rubber hose to the roller. You can adjust the amount of spray according to the speed of the roller.
