Dust Blowing Test Chamber ISO-20653-2006、GBT-2423.37

Test Purpose：

The test can be used to simulate open sand and dust air ambient conditions induced by natural or artificial disturbances such as vehicle motion.

Meet The Standards：

GB/T2423.37-2006 Lc1 or Lc2 test,IEC60068-2-68 Lc1 or Lc2 test Dust blowing test for ISO 20653:2006, procedure I procedure test for GJB150.12A-2009, procedure I procedure test for MIL-STD-810H 510.7

Design Principle：

Design a conical funnel, the bottom of the dust collector, at the dust extraction mouth (right) install high pressure turbine circulation fan inlet, the dust to the inner box at the bottom of the box through the bottom to the left up, before the disposal box, blow into the dust dust from the left to the test box, dust horizontal dust to the right, so as to start to cycle.

Control Box and Test Box Are of the Overall Type：

The bottom of the room body is funnel-shaped, and the dust shaking motor at the bottom will assist in dust recovery

The test box is approximately a cube, whose edge length in the airflow cross section is at least 3 times the maximum of the vertical or horizontal side length of the vertical air flow direction. The test box has the heating function;

The test box has a pretreatment box, and the two boxes have the same air flow section. The air diversion sheet is placed at the back of the entrance of the air flow channel leading to the front box, produce horizontal laminar air flow through the overall arrangement, arrange the blower device producing air flow after the test box, and draw air from the test box and send it to the front treatment box through the air flow channel;

The dust device is of external type and connected by air duct.
