Features :
·       HASTON dust testing chamber vertical circulation airflow carries dust and the test dust can be recycled;
·       Using a single high-power low-noise centrifugal fan, according to the test requirements to adjust wind speed by conversion speed regulator.
·       The whole ventilation uses imported stainless steel plate, The bottom of the air duct is connected with the conical hopper, the air inlet and outlet of the fan are directly connected with the air duct, and then the top diffuser of the working chamber is connected to the working chamber body in proper position to form an "O" closed vertical blowing dust circulation system, so that air flow can flow smoothly and the maximum dust dispersed evenly;
The test box for low-voltage electrical appliances, electrical appliances, instruments, meters, lamps, household appliances and other products in the storage, transportation and use of sand and dust are often affected by the environment. Especially cars, electrical appliances by the impact of dust is more significant. This equipment is used artificial dust environment, to test the test of dust resistance of the test equipment, test specimens in this environment in the sealing and corrosion resistance
Working principle:
Centrifugal fan is the main source of dust movement, the high-speed operation of the fan so that dust into the fan due to the centrifugal force of the role of fan blades into the dust pipe dust. The wind speed of the pipeline is usually more than 7.5m / s (too low wind speed will make the dust precipitate in the pipeline will cause the test tube can not work). The dust line was sprayed from above into the test chamber and passed through the sample at a rate of> 2 m / s. Sand and dust chamber As the lower part of the working box for the funnel, it can precipitate down the dust into the lower part of the 72 × 50um filter. Through the vibrating motor vibration, less than the diameter of the filter hole in the dust and centrifugal fan sucked so back and forth.
