Application background:The destruction of products and materials by natural dusts (sand,
dust, dust, etc.) causes incalculable economic losses each year.
The damage is mainly caused by corrosion, fading, deformation,
strength decline, expansion, mildew, etc., especially electrical
products due to the dust caused by short circuit and very easy to
cause fire. Therefore, for specific products or materials to carry
out shell dust test is a necessary key program. |
Equipment function: The main function of the equipment is to test the physical and other related properties of the products of electrical and electronic products, lamps, electric cabinets, electrical components, automobiles, motorcycles and their parts, etc. under simulated dust weather conditions. After testing, through the test to determine whether the performance of the product to meet the requirements, in order to product design, improvement, verification and use of factory inspection. |
II.Implementation standards | Compliance with IEC60529:1989+A1:1999 +A2:2013 Degrees of protection provided by enclosures (IP Code), GB4208-2008 "Enclosure Protection Class (IP Code)" 13.4, 13.5 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. |
1,It is suitable for testing the IP5X and IP6X dust levels of
products.
2,The shell is made of domestic high-quality steel plate, the surface
is sprayed with paint, beautiful and durable.
3,Inner box, sample frame, etc. are made of stainless steel plate to
ensure that the use of long time does not rust.
4,The door has a transparent observation window (tempered glass
material), the box is equipped with LED lights, to facilitate the
observation of internal testing.
5,The bottom of the device is a device for replacing dust, which can
easily be replaced by 100% of the used dust.
6,In order to ensure that the dust does not stick to the wall and
condensation, a special set of devices installed, the device
working time adjustable, and can automatically alternate work.
7,There is a suction pipe in the box, the sample can be completed
vacuum action (need to set aside the sample hole).
8,Sand Dust Test Box control system: The use of Taiwan Granville LUN
7-inch touch screen + Panasonic PLC, using the full Chinese
display, can display the year, month, day, time, working hours. The
dust blower, dust vibration and total test time can be controlled
respectively, and the controller has the following kinds of
arbitrary setting control functions;
a. Dust blowing time (stop, Blow): Continuous, periodic blown dust
arbitrary selection time set;
b. Vibration Time: Vibration and stop vibration time are
automatically alternated;
c. Preset test time: The maximum test time is 99 hours and 59
minutes;
d. Power on: Break-pass-break.
9,Heating system: The circulation duct is equipped with heater
heating dust, to avoid dust condensation, pipe hoop-type MICA plate
heating ring.
10,Vacuum system: equipped with vacuum pump, vacuum pressure, air
filter, flow meter, pressure regulator triple unit, connecting
pipe.
11,Equipment in line with national standards under the premise of all
aspects of performance are stable based on more practical and easy
to control. And, the equipment has easy to install, simple
operation, basically do not need daily maintenance and other
characteristic.
