Sand Dust Test Room Auto Parts Test Equipment Dust Concentration 2～4kg/M³
Products
Introduction:
The equipment is suitable to test whether electrical electronics,
automobiles, motorcycle parts, shells and seals can guarantee the
good performance of the equipment and the original in a large dust
environment.To test the use, storage and transportation performance
of electronic and electrical products, automobiles, motorcycle
parts, and seals in a large dust environment.The purpose of the
test was to determine the possible harmful effects of the particles
carried by the air flow on the electrical products.The test can be
used to simulate open dust-air ambient conditions induced by
natural or artificial perturbations, such as vehicle motion.Auto Parts Test Equipment
Meet the standards:
Test requirements of household appliances, low voltage appliances,
automobile, motorcycle parts enclosure in GB4208-2017-13.4,
IEC60529:2013-134, GBT2423.37-2006-La2, IEC60068-2-68-La2,
ISO20653-La2.Auto Parts Test Equipment
Design
principle:
The powder circulating pump in the sealing test box can be replaced
by other methods of suspending talc powder.Stalc powder was
filtered by metal holes.The wire is 50 m in diameter and the sieve
size is 75 m.The talc powder is 2kg per cubic meter and shall not
exceed 20 times.Maintain uniform suspended dust with sufficient
density in the test box.
The test shell is placed in the test box, and the pressure in the
shell should be kept with a vacuum pump below the atmospheric
pressure, and the air pressure can also be changed to realize the
periodic change of the air pressure in the test box.
The purpose of the test is to draw the air in the box into the
subject equipment using the pressure difference. The gas pumping
volume is 80 times the shell volume of the subject, and the pumping
rate shall not exceed 60 times the shell volume per hour.Under any
case shall the pressure difference not exceed 2kPa.Auto Parts Test Equipment
The instrument shall have an emergency stop device to ensure the
safety in the abnormal test.
Seal the test box cover (door) shall be sealed reliably. It is
recommended to adopt conductive materials on the inner wall of the
test box, and the grounding shall avoid static accumulation.
Test dust recovery and treatment function shall be required, and
all operation functions of the equipment shall meet the
requirements of clause 13.4 in standard GB4208-2008.Auto Parts Test Equipment
