Dustproof Environmental Simulation Test Chamber Applied in LED or
Luminaries
Brief Introduction:
The Dustproof 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.
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> 2m/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.
The main test parts include lights, instrumentation, safety belt,
seat regulator, electric dust cover, steering gear shaft and locks,
to test its dust resistance and movement safety.
Flow dust testing in accordance with IEC60529 and MIL/STD810D.
