Overview
GDJW-225C high and low temperature alternating test chamber is produced by ZKHS, which is suitable for the performance detection of aviation, aerospace products, information electronics, Instruments, materials, electrical, electronic products and various electronic element gas parts in high and low temperature environment. The equipment adopts numerical control machine tool processing and molding, beautiful and generous shape, easy to operate.
Features
1. The box body is processed and formed by numerical control machine tool, with beautiful and generous shape, and adopts no-reaction handle, which is easy to operate.
2. The inner tank of the box is made of imported stainless steel (SUS304) mirror plate, and the shell is sprayed with A3 steel plate to increase the appearance texture and cleanliness.
3. The large observation window is equipped with lights to keep the box bright, and the tempered Glass embedded in the heating element can be clearly observed in the box.
4. The left side of the box is equipped with a 50mm diameter test hole, which can be used for external test power or signal wires.
5. The temperature control adopts a "7.0" inch large-screen Touchscreen temperature and humidity control instrument, which has simple operation settings and a locking function to avoid accidental touch.
6. With P.I.D automatic calculation function, it can immediately correct the temperature change conditions, making the temperature control more accurate and stable.
7. The refrigerator adopts the original French "Taikang" fully enclosed Compressor unit, and the refrigeration system adopts the unit or binary low temperature circuit system design.
8. The multi-wing blower is used for strong air circulation to avoid any dead ends and ensure uniform temperature distribution in the test area.
9. The air path circulates the air outlet and return air design, the wind pressure and wind speed meet the test standards, and the temperature stabilizes quickly at the moment of opening the door.
10. Heating, cooling, and complete system independence can effectively reduce testing costs, increase lifespan, and reduce failure rates.
Principle
The test chamber adopts the original French "Taikang" fully enclosed Compressor unit and unit or binary low temperature circuit system through the refrigeration system, combined with the nickel-chromium alloy electric heating heater of the heating system, to achieve temperature control. The control system adopts a large-screen Touchscreen temperature and humidity control instrument with P.I.D automatic calculation function, which can accurately and stably adjust the temperature. The air circuit circulation system uses a multi-wing blower to strongly supply air to ensure uniform temperature distribution in the test area.
Applications
Aviation, Aerospace Products, Information Electronics, Instruments, Materials, Electrical, Electronic Products, Various Electronic Components
Standards
G B 2423.1 - 2008 Test A "High Temperature Test Method", G B 2423.2 - 2008 Test B "Low Temperature Test Method", GJB150A.3, GJB150A.4
Steps
1. Power frequency AC280V +/- 10% or AC380V +/- 10% 50Hz three-phase five-wire system.
2. Set the test conditions through the large-screen Touchscreen temperature and humidity control instrument, including temperature range, time, etc.
3. Start the equipment, and the refrigeration and heating systems work independently to achieve temperature changes.
4. Use the observation window and lighting to monitor the situation in the box, and connect the external test line through the test hole if necessary.
5. After the test is completed, the equipment automatically stops and records the test data.
Notice
• Operating Environment Temperature should be in the range of 5 ℃~ + 30 ℃, humidity ≤ 85% R.H.
• Avoid touching the controller artificially to prevent changing the set temperature value.
• Regularly check the safety protection device, including leakage, short circuit, overtemperature, motor overheating, Compressor overvoltage, overload, overcurrent protection.
• Power frequency is stable and meets the requirements of AC280V +/- 10% or AC380V +/- 10%.
• Pay attention to temperature changes when opening the door to avoid burns or frostbite.
• Keep the cabinet clean and maintain the refrigeration and circulation system regularly.
