Overview
QLH-800 (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, Appearance is beautiful and generous, easy to operate.
Features
1. The box is processed and formed by numerical control machine tool, the shape is beautiful and generous, and the operation is easy with no reaction handle
2. The inner tank of the box is made of imported stainless steel (SUS304) mirror plate argon arc welding
3. The box shell is sprayed with A3 steel plate, Appearance and texture are good and cleanliness is high
4. Adopt intelligent program microcomputer controller, with timing function, accurate and reliable temperature control
5. Large observation window with lighting, tempered Glass, easy to clearly observe the situation in the box
6. The hot air circulation system consists of high temperature resistant fans and special air ducts to ensure uniform temperature in the working room
7. Equipped with low-speed turntable device
Principle
The hot air circulation system runs continuously at high temperature, combined with the special air duct design, so that the temperature in the working room is kept uniform. The intelligent microcomputer controller precisely controls the temperature, and can adjust the ventilation time and ventilation volume through the ventilation system 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 "Air Heat aging test chamber", GB/T3512-2014, GB/T7141-2008, GBT 2951.42-2008, GB/T 2951.11 - 2008
Steps
1. Power on and select the appropriate voltage (AC220V +/- 10% or AC380V +/- 10%)
2. Set the required temperature range (RT + 10~ 200 ℃)
3. Adjust the ventilation time (adjustable from 3min to 100h) and ventilation volume (3 to 100 times/h)
4. Set Timer Range (0~ 9999 M, H adjustable)
5. Start the device and monitor the running status through the LED digital display controller
6. Observe the test in the box through a large observation window
7. Turn off the equipment after the test is completed
Notice
• Power frequency compliance before use (AC220V +/- 10% or AC380V +/- 10% 50Hz three-phase five-wire system)
• Do not open the box door at will during the operation of the equipment, so as not to affect the temperature uniformity
• Regularly check whether the safety protection function is normal, including leakage, short circuit, over temperature, motor overheating, and over current protection
• Keep the equipment well ventilated to avoid blocking the heat dissipation channel
• Use proper tools when cleaning to avoid scratching stainless steel liners and tempered Glass windows
• Non-professionals should not disassemble or repair the internal components of the equipment
