Sand and Dust Tester Chamber Testing Machine
Application
This equipment is suitable for testing electric and electronic products, automobile, motorcycle parts, and seals to prevent sand and dust from entering the seals and shells in a sandy dust environment. To test the performance of the use, storage and transportation of electronic and electrical products, automobile and motorcycle parts, and seals in a sandy dust environment. The purpose of the test is to determine the possible harmful effects of particles carried by the airflow on electrical products. The test can be used to simulate open sand and dust air environmental conditions induced by natural environment or man-made disturbances such as vehicle movement.
Design Principle
Design a cone-shaped funnel with a dust collection port at the bottom, and install a high-pressure turbine circulation fan suction port at the dust extraction port (bottom), and send the pumped dust to the top of the inner box and freely fall from top to bottom through the top of the box, thus starting The cycle repeats itself.
