Ventilation aging test chamber

Ventilation aging test chamber

1Ventilation aging test chamberpurpose

lThe ventilation aging test chamber is suitable for heat resistance testing of electrical insulation materials, as well as ventilation aging testing of electronic components and plasticized products. Assess and judge its adaptability for storage and use under high temperature environmental conditions, and simulate the high temperature andatmospheric pressureAfter aging in the air, measure its performance and compare it with the performance of the unaged sample.

IIVentilation aging test chamberworking principle

lThis device adopts the Balanced Temperature Control (BTC) method, which controls the output of the heater through PID automatic calculation based on the set temperature point when the system is working continuously, achieving a dynamic balance.

VIVentilation aging test chamberEquipment structural characteristics and configuration

lThe test box body is in the form of an integral structure, with the heating system located at the lower rear of the box and the control system located on the right side of the test box. Install air inlet and hot air outlet on the top and bottom of the box to ensure reliable operation of the test chamber

lIn the air duct interlayer at the left and right ends of the studio, heaters, fan blades, and other devices are distributed. The test chamber is a single door sealed with woven asbestos strips.

lThere is an observation window on the box door (Not installed above 250 ℃).

lIrregular sample holder

lThe inner wall of the studio is processed and formed using SUS304 stainless steel brushed plate

lThe shell is processed and formed from cold-rolled sheet metal, and the surface is treated with electrostatic powder coating.

lThe insulation layer adopts insulation cotton.

lUsing a digital temperature controller to detect and control the required temperature inside the box, the heating actuator uses SSR solid-state relays.

lStainless steel fin electric heater

lMotor, axial fan
