Do you have any idea about the sand dust test chamber ? If you are looking for a sand dust test chamber, Please keep the patience to read this article which may easier to make you understand what is the dust test chamber and how it works.
In fact, There has many suppliers who can supply the sand dust test chamber for you. Such as Espec dust test chamber, Weiss dust test chamber, PTL dust test chamber. They are all the good quality manufacturers, But their selling price is expensive. So if you don’t have enough budget but still want to buy a good quality sand dust test chamber, Inquiry to the China supplier is a good option.
The sand and dust test chamber is suitable for testing the sealing performance of the shell of the product. It is mainly used for the test of the two grades of IP5X and IP6X specified in the protection standard of the shell. It is mainly to simulate sandstorm weather caused damage to lockset, auto parts, seals, electrical instruments and other products. Through the test, add some protective screening or sand and dust measures in the general equipment installation and application. Improve the product’s ability to resist and protect dust.
Products to be tested for dustproof performance and IP dustproof grade: Communication products, Automobile parts (such as automobile rearview mirror, automobile acoustics, automobile electronics, automobile lighting, automobile lamps, motorcycle lamps, motorcycle rearview mirror), Outdoor lighting and signal devices.
The dust test chamber can effectively help users to evaluate the sand and dust resistance of the sample, and the ability to resist the impact of dust that may block the opening, infiltration cracks, gaps, bearings and joints, and it is not affected by the wear or blockage of large sand particles with sharp edges reduce the performance, efficiency, reliability and maintainability. Sand and dust test chamber is applicable for sand and dust test of various auto parts, including car lamp, instrument, electrical dust cover, steering system, door lock, etc.

Working principle of sand dust test chamber : Centrifugal fan is the main energy source for dust powder movement. The high operation of the blade causes the dust powder to be sucked into the fan. Because of the centrifugal force of the fan blade, Dust powder enters the pipe.
Winds entering the pipe generally exceed 7.5m/s (too low wind speed will cause dust powder to precipitate in the pipe, which will make the test tube unable to work). The dust powder is sprayed into the test room from above, Passing through the sample at > 2 m/s.
Since the test room of sand and dust test chamber is funnel type, So the precipitated dust powder can slide into the lower 72 x 50um filter network. Because of the motor vibrating, Dust powder which smaller than the diameter of the filter mesh is also inhaled by the centrifugal fan. The sand dust test chamber will work for testing by the endless cycle ways continuous.
