In the salt spray test chamber, the temperature of the test chamber, brine tank, and saturated air are required to be 35 degrees, 35 degrees, and 47 degrees during the test.
The temperature requirements of each part are different. The temperature of the saturated air is 47 degrees. The main reason is that the high-pressure air needs to absorb a lot of heat due to changes in pressure and volume during expansion (PVT = K, that is, between pressure, volume, and temperature) The relationship is constant), if the high-pressure saturated air is not preheated to a certain temperature in advance, the temperature in the test box will inevitably be lowered, so that the experiment is not standard and misjudgment occurs.
In general, the high-pressure saturated air under a kilogram of pressure needs to be 12 to 13 degrees higher than the temperature of the test box (similarly, if it is a copper acetate test, the temperature of the test box, test liquid tank, and saturated air are: 50 degrees, 50 Degrees, 63 degrees).
Saturated barrels play a key role in salt spray corrosion tanks. They are also known as "saturated air barrels" as the core part of salt spray test chambers. Their function is to humidify and heat the compressed air and filter oil, so it is also called "pressure barrel ". Various other parts are also worthy of our attention
1. Whether the saturated air bucket is wet-heated, the method used by the low-end brand is dry-heated, that is, the high-pressure air passes through the copper tube buried in the water of 47 degrees, and does not directly contact the water of 47 degrees. It is conceivable that the high-pressure air passing quickly can reach 47 degrees? At the same time, the high-pressure air from the air station is generally very dry. Since it is not in direct contact with water, how to ensure its full integration with salt water and test Humidity above 85% in the box.
2. Is there a constant temperature system dedicated to salt water? Generally speaking, at 35 degrees, the analytically pure solubility is the best.
3. What is the durability of the nozzle? If it is an ordinary glass product, it generally consumes relatively quickly and must be changed frequently.
The water consumption time of the saturated barrel of the salt spray test chamber is shorter. In fact, the water cycle of the saturated barrel is related to the size of the nozzle, the amount of settlement and the volume of the saturated air barrel. Saturated buckets have different water cycles under different conditions
