Use conditions of high and low temperature and low pressure test chamber
One of the operating conditions of the high and low temperature and low pressure test chamber:
Environmental conditions
1. Temperature: 15 ℃ ～ 35 ℃;
2. Relative humidity: not more than 85%;
3. Atmospheric pressure: 80kPa ～ 106kPa
4. There is no strong vibration and corrosive gas around;
5. No direct sunlight or direct radiation from other cold and heat sources;
6. There is no strong airflow around. When the surrounding air needs to be forced to flow, the airflow should not be directly blown onto the box;
7. The influence of the magnetic field of the control circuit of the surrounding interference-free test box;
8. There is no high concentration of dust and corrosive substances around.
The second use condition of high and low temperature and low pressure test chamber:
Power supply conditions
1. AC voltage: 220V ± 22V or 380V ± 38V;
2. Frequency: 50HZ ± 0.5HZ.
The third use condition of high and low temperature and low pressure test chamber:
Water supply conditions should use tap water or circulating water that meets the following conditions:
1. Water temperature: not higher than 30 ℃;
2. Water pressure: 0.1MPa ～ 0.3MPa;
3. Water quality: in line with industrial water standards.
The fourth condition of high and low temperature low pressure test chamber:
Test load conditions The load of the test chamber should meet the following conditions weekly:
1. The total mass of the load is not greater than 80KG per cubic meter of studio volume
2. The total volume of the load is not greater than 1/5 of the studio volume
3. On any cross section perpendicular to the prevailing wind direction, the sum of the load areas should not be greater than 1/3 of the cross-sectional area of ​​the working room at that place, and the flow of airflow should not be blocked when the load is placed.
