The sand and dust test chamber is suitable for testing the sealing performance of product shells, mainly used for testing the IP1X-IP6X levels specified in the shell protection level standards. Mainly simulating the damage caused by sandstorm weather to locks, automotive and motorcycle components, seals, power instruments and other products. Simultaneously applicable for testing the sealing performance of product casings.

Box Structure

1、 Material composition

Outer wall material: t=1.2mm electrostatic spray coated steel plate, beautiful and generous

Inner wall material: t=1.0mm SUS304 stainless steel plate

Selected materials are used for processing and forming. The surface of the shell and the outer wall of the door are made of steel plates, and the surface is treated with electrostatic color spraying, which is beautiful and smooth. Coordinated color matching, curved design, smooth and natural lines.

2、 Inner shell of the box

The inner liner material is made of stainless steel plate, designed to be a sealed space during operation, where samples can be placed for shell sealing tests. The indoor sample rack and other accessories are made of stainless steel plates, with a reasonable design and durability.

Shape: funnel-shaped

Note: With adjustable vibration period, flying dust can gather near the blowing hole.

3、 Work door

Form: hinged double door

Observation window size approximately: width 450mm x height 500mm

4、 Dust device

Location: bottom of the test chamber. Note: replaceable

5、 Observation window

Location: Installed on the box door

Tempered glass with manual dust scraper

Note: The status of the sample inside the box can be observed when the dust blowing stops.

6、 Dust blowing motor

Forced convection balance temperature and humidity control

Shell: Made of special aluminum alloy

Advantages: Strong sealing, low noise, high wind speed.

The equipment has a vertical circulation airflow carrying dust, with talc powder as the dust. The dust is blown into the circulating air duct through the fan at the bottom of the funnel, and then evenly diffused by the air outlet guide plate on the upper part of the equipment. With the help of the circulating airflow, the dust can be uniformly suspended in the test chamber. The amount of talc powder used is 2kg per cubic meter of the volume in the test chamber, and the number of uses does not exceed 20 times.

7、 Operation (testing) hole

Size: Φ 50mm Quantity: 1 set

Note: The location can be customized according to customer needs, with stainless steel cover and rubber plug.

8、 Dust collection device

Set up a dedicated bypass circuit to collect sand and dust in the funnel-shaped bottom plate of the box. If necessary, a vacuum cleaner can be used to suck out the sand and dust;

9、 Activity Wheel

The bottom of the test chamber adopts high-quality, fixable universal Fuma wheels

10、 Vacuum system

Equipped with a vacuum generator and an electronic differential pressure sensor, the differential pressure of the specimen is controlled through a pressure regulating valve;

11、 Sample rack

A stainless steel testing platform with a load of 1000kg and equipped with an external mobile platform.
