Section 3: Test Box Structure
Both the inner and outer shells are made by importing PP plastic boards, which are softened through a special mold at high temperature and then cooled to form.
2. The joints between panels are milled to form a 90-degree right angle, then filled with molten plastic welding wire using high-temperature welding tools. The welds become even more robust after cooling.
3. The external humidity and temperature control cabinet is used to create the specified humidity and temperature environment, which then enters the box and circulates within it.
4. The equipment is designed with an air conditioning system, which includes a refrigeration system, heating system, and humidification system. The air conditioning system produces temperatures and humidity that meet the test requirements, and there is a stirring chamber between the inner shell and the outer shell of the equipment.
After uniform mixing, the solution is introduced into the box, simultaneously with a certain concentration of sulfur dioxide gas being fed in. The flow rate is controlled to achieve the specified range, with the concentration being monitored by a sulfur dioxide concentration meter.
5. The equipment heats up and warms quickly, with even distribution of temperature and humidity.
6. The heating and humidifying elements utilize titanium metal heating tubes, which are corrosion-resistant and have a long service life.
7. The box door is made of tempered glass, offering easy and smooth opening and closing.
8. Utilizes corrosion-resistant silicone rubber seals to ensure no gas leakage.
9. The sample frame structure design complies with national standards and can also be hung. It has a high load capacity and is easy to place the samples.10. Sulfur Dioxide (Hydrogen Sulfide) gas, after exiting from the cylinder, undergoes pressure reduction and is then controlled by a corrosion-resistant solenoid valve to enter the分流管道 at the bottom of the housing through a flow meter, uniformly mixing with the air inside the housing, concentration
The concentration of sulfur dioxide (hydrogen sulfide) can be detected and controlled by a monitoring instrument. It includes over-temperature protection, low-water level alert, ensuring safe operation.
11. The refrigeration system of the equipment is installed at the bottom, primarily for cooling and dehumidifying purposes.
12. The equipment control system is designed on the right side of the cabinet, with simple operation.
13. The specially designed sulfur dioxide gas filtration unit can quickly and effectively filter out any residual sulfur dioxide gas inside the container after testing, ensuring no pollution to the atmosphere, and is easy to operate.
Four: Control System:
1. Temperature Controller: Imported touchscreen controller, with accurate and stable control, no drift over long-term operation. Temperature and humidity programs are programmable, and the operation is simple.
2. Precision: 0.1℃ (Display Range)
Resolution: ±0.1℃
4. Temperature Sensor: PT100 Platinum Resistance Thermometer
5. Control Method: Heat Balance Temperature and Humidity Control
6. Temperature and humidity control employs a P.I.D. + S.S.R. system for synchronized channel coordination control.
7. Features automatic calculation capability, allowing for immediate adjustment of temperature and humidity change conditions, ensuring more stable temperature and humidity control.
8. This test chamber's return air inlet is equipped with an automatic defrosting device (which prevents condensation from accumulating on the refrigeration evaporator during testing, thus avoiding ice blockage).
9. Execution Components: Schneider AC Contactors, Miniature Relays, Solid State Relays
V. Protection System:
Overall equipment overheating, fan overheating protection, overall equipment phase failure/reverse phase, overall equipment timing, other protections include leakage, operation indicator, and automatic shutdown after fault alarm.
