Ventilation Aging Test Chamber Simulating Aging Environment In Air At High Temperature And Atmospheric Pressure
Product Usage:
The ventilation type aging box is suitable for the heat resistance
test of electrical insulating materials, the gas aging test of
electronic parts and plastic products, etc.; the evaluation and
judgment of the adaptability of storage and use under high
temperature environment conditions, the sample is simulated The
properties were measured after aging in air at high temperature and
atmospheric pressure and compared with the performance of unaged
samples.
Test Standard:
Meet the standard "air heat aging test chamber"
American Standard: Meet the requirements of the UL1581/UL2556
standard.

(No-load test)
Ventilation system:
01 | Air exchange rate: | 100-200 times per hour |
02 | The ventilation control is manually controlled | and the aperture is adjustable by 100mm |
03 | Adjustment mode | the ventilation hole is manually adjustable |
04 | Power consumption meter | KWH power meter |
05 | ventilation | natural ventilation |
06 | The air outlet is located at the top of the machine | and the manual switch air outlet is used |
The formula for calculating the number of air changes in the ventilation aging test chamber is as follows:
among them:
N--gas exchange times, times/hours;
P1--the average power when the valve is closed, W;
P2--the average power when the valve is open, W;
T1--ambient temperature, °C;
T2--tank temperature, °C;
V--the internal volume of the ventilation aging test chamber, L;
D-- Ambient air density at the test, g/L.
Circulating air supply system:
1. Air supply mode: internal hot air circulation;
2, the motor is high temperature resistant long shaft special type,
power 370W/220V;
3. The wind wheel is 7.5-inch multi-blade turbine type;
Security system:
1. Over-temperature protection system: When the temperature is out
of control, when the over-temperature protection set temperature is
exceeded, the heating supply is automatically stopped, thus
protecting the safety of products and machines;
2. Circuit protection system: grounding protection, fast insurance,
etc.
Power supply unit:
1. voltage 220V
2. Power 3.5KW
3. current 16A
