Speaking of the purpose of the constant temperature and humidity test box test, as with other industry product tests, the purpose is to assess the adaptability of the ship's electronic equipment operating under conditions of high relative humidity accompanied by temperature cycling. There are two common temperature points, which are high temperature 40 degrees plus or minus 2 degrees, normal temperature 25 degrees plus or minus 2 degrees; corresponding humidity is 93% plus or minus 3%, 95% to 100% (relative humidity). In the normal test, the number of test cycles is generally 2, 4, and 6, and one cycle is 24 hours.
During the test, the placement of the test sample is also required. Make sure that there is a proper distance between the samples, do not overlap each other, and heat to the temperature of the constant temperature and humidity test chamber. In addition, the sample should be in the state of not being packaged, not energized and ready to work, and placed in the test box according to the actual ship use state, and the temperature and humidity are adjusted to the specified values. The number of test cycles is determined by the relevant standards according to 2, 4, and 6. Select.

Detailed introduction:
Photovoltaic solar spiral pile is a kind of spiral drilling pile. Its characteristics include the connection of drill bit and drill pipe, drill bit or drill pipe connecting a power source. After this photovoltaic solar spiral pile is placed underground, it will no longer Take it out and use it directly as a pile.
The drill bit of the photovoltaic solar spiral pile includes the spiral drill bit at the bottom.
Specific structure:
1. Use steel pipe in the middle part
2. The top is the connecting pipe
3. The drill pipe of the photovoltaic solar spiral pile includes the upper connecting pipe
4. Steel rod in the middle part
5. The lower connecting shaft
6. After the pile is driven into the ground, it is no longer taken out, but used as a pile directly.
On the basis of the "end-bearing pile" structure and "friction pile" structure used in the construction process, it is widely used in the construction of a variety of ground piles, ground anchors, and randomly structured ground piles.
