Dust test chambers are made for the simulation of dust and sand conditions. These dust chambers are used for evaluating the effects of dust-filled environments in order to validate product seal integrity. Dust test chambers are applied in Automotive, Electro-technical products, Materiel, Coatings, Solar Energy, etc for IPX5 and IPX6 test.
The Dust-proof Test Chamber is according to IEC60529, IEC 60598, GB2423.37-89 (Test L:dust test methods), GB 4208-93 protective casing grade (IP code), GB/T 4942.2-93(protective casing grade of low-voltage apparatus), GB 7000.1-1996, GB 7001-1986(protective casing grade of lamps),DIN40050 and IP5K0.
Working principle of chamber:
Centrifugal fan is the main source of dust movement, the high-speed operation of the fan so that dust into the fan due to the centrifugal force of the role of fan blades into the dust pipe dust. The wind speed of the pipeline is usually more than 7.5m / s (too low wind speed will make the dust precipitate in the pipeline will cause the test tube can not work). The dust line was sprayed from above into the test chamber and passed through the sample at a rate of> 2 m / s. Sand and dust chamber As the lower part of the working box for the funnel, it can precipitate down the dust into the lower part of the 72 × 50um filter. Through the vibrating motor vibration, less than the diameter of the filter hole in the dust and centrifugal fan sucked so back and forth.
