广州棋牌 working principle

 

 

The dust of a certain concentration is blown across the surface of the test sample by a fan at a certain velocity. The test sample is exposed to dry sand or dust-filled atmosphere, and the ability to resist the infiltration effect of dust particles, the ability to resist the abrasion or blocking effect of sand and gravel, and the ability to store and operate.
 
The dustproof test chamber is provided with air flow for vertical circulation of dust, and the dust used in the test can be recycled. The equipment itself has good sealing performance, and the condition of indoor test can be clearly observed during the test.
 
Before the test, the dustproof test chamber should be placed in atmospheric environment at room temperature for about 2 hours. According to relevant standards, visual inspection and electrical and mechanical performance testing can be carried out on test samples. Place the sample on the shelf (center) in the sand and dust box.
