Overview
QLH-010 (250 ℃) ventilation aging test chamber is produced by ZKHS, which is suitable for the heat resistance test of electrical insulation materials, as well as the ventilation aging test of electronic spare parts and plasticized products. The equipment is processed by numerical control machine tools, with beautiful appearance 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, which increases 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. The large observation window is equipped with lights to keep the box bright, and tempered Glass is used to clearly observe the situation in the box at any time.
6. The hot air circulation system is composed of fans and special air ducts that can operate continuously at high temperatures, and the temperature in the working room is uniform.
7. Rotation speed turntable for aging unit.
Principle
The equipment precisely controls the temperature through the microcomputer integrated controller, and uses the high temperature and low noise motor to drive the multi-leaf centrifugal wind turbine to form a hot air circulation system, so that the temperature in the working room is uniform. At the same time, the equipment has adjustable ventilation function, and simulates the aging environment by controlling the ventilation time and ventilation volume.
Applications
Electrical insulation material heat resistance test, electronic parts ventilation aging test, plasticized products ventilation aging test
Standards
GJB7444-94 "Hot air aging test chamber", GB/T3512-2014, GB/T7141-2008, GBT 2951.42-2008, GB/T 2951.11 - 2008
Steps
Connect the power supply (AC220V +/- 10% or AC380V +/- 10% 50Hz three-phase five-wire system).
2. Set the required test temperature, ventilation time, ventilation volume and timing time through the LED digital display microcomputer controller.
3. Place the sample on the turntable in the box.
4. Start the equipment and start the test.
5. During the test, the conditions in the box can be observed through a large observation window.
6. After the test reaches the set time, the equipment can be automatically stopped or manually stopped.
Notice
• Power supply voltage must be used under the specified equipment.
• When placing the sample, make sure it does not affect the hot air circulation.
• When the equipment is running, do not open the box door frequently.
• Safety protection functions such as leakage, short circuit, over temperature, motor overheating, over current, etc., but safety still needs to be paid attention to during operation.
• Regular maintenance inspections to ensure the normal operation of the equipment.
