IEC60529 IP56X Sand and dust test machine
Testing Standard: In accordance with IEC60529: 2001 "Degrees of protection provided by enclosures (IP Code)", GB4208-2008 "Shell protection class (IP code)" 13.4,13.5 terms and Figure 3 and GB7000.1 "Lamps Part I: General requirements and tests" 9.2.1, 9.2.2 and the requirements of Figure 6.
Usage: The test box for low-voltage electrical appliances, electrical appliances, instruments, meters, lamps, household appliances and other products in the storage, transportation and use of sand and dust are often affected by the environment. Especially cars, electrical appliances by the impact of dust is more significant. This equipment is used artificial dust environment, to test the test of dust resistance of the test equipment, test specimens in this environment in the sealing and corrosion resistance
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.
