Product features:
1. The equipment is a walk-in structure with spliced warehouse boards. There is a funnel in each of the four corners. The middle flat adopts a dust brush structure. The side-through dust brush structure brushes dust into the funnels on both sides.
2. There is a rotating sand and dust feeding device at the air inlet end of the working room to meet the needs of dust blowing.
3. The circulating air duct is equipped with a heating and dehumidification device.
4. There is an observation window on the door. The test box has double doors and is sealed with double layers of aging-resistant silicone rubber.
5. The outer wall material of the test room and whirlpool duct is made of high-strength double-sided galvanized steel plate with fine powder baking paint on the surface. The inner wall is processed and formed by SUS304 stainless steel plate. The frame is made of 10# square tube after anti-rust treatment and spraying.
6. Temperature and humidity control uses an intelligent controller (relative humidity uses a direct-reading sensor) (panel control uses a touch screen).
Product usage:
This equipment is suitable for testing electrical and electronic products, automobile and motorcycle parts, and seals in sand and dust environments to prevent sand and dust from entering the seals and shells. To test the performance of electronic and electrical products, automobile and motorcycle parts, and seals in use, storage, and transportation in sandy and dusty environments. The purpose of the test is to determine the possible harmful effects of particles carried by airflow on electrical products. The test can be used to simulate open sand and dust air environmental conditions induced by the natural environment or man-made disturbances such as vehicle movement.
