Overview
QLH-100 (200 ℃) ventilation aging test chamber is produced by ZKHS, which is suitable for the heat resistance test of electrical insulation materials and the ventilation aging test of electronic spare parts and plasticized products. The box body is processed by numerical control machine tool, with beautiful structure and easy operation.
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 argon arc welding.
3. The shell of the box is sprayed with A3 steel plate to increase the appearance texture and cleanliness.
4. Adopt an intelligent program microcomputer controller with temperature control protection, with timing function, accurate and reliable temperature control.
5. Large observation window with lighting, tempered Glass, easy to clearly observe the situation inside the box.
6. The hot air circulation system is composed of high temperature resistant fans and special air ducts to ensure uniform temperature in the working room.
7. The device is equipped with a low-speed turntable.
Principle
The test chamber achieves uniform temperature in the working room through a hot air circulation system, a fan that runs continuously at high temperature and a special air duct. The intelligent program microcomputer controller is used for precise temperature control, and is equipped with a ventilation function to simulate the aging environment.
Applications
Electrical insulation material heat resistance test, electronic parts ventilation aging test, plasticized products ventilation aging test
Standards
GJB7444-94、GB/T3512-2014、GB/T7141-2008、GBT 2951.42-2008、GB/T2951.11-2008
Steps
Connect the power supply to ensure that the voltage meets the requirements of AC220V +/- 10% or AC380V +/- 10% 50Hz three-phase five-wire system.
2. Set controller parameters, including temperature range, ventilation time, Timer Range, etc.
3. Start the device and monitor the running status through LED digital display.
4. Observe the conditions inside the box and use large observation windows and lighting.
5. After completing the test, turn off the device and disconnect the power supply.
Notice
• Power frequency check before use to avoid overvoltage or undervoltage.
• Ensure that the safety protection function is normal, including leakage, short circuit, over temperature, motor overheating, and over current protection.
• Pay attention to high temperature parts during operation to prevent burns.
• Regularly maintain the hot air circulation system and turntable to ensure the stable operation of the equipment.
• Avoid use in humid or flammable environments to prevent accidents.
