3. The environment in which the device is used

1. Temperature: 15°C~35°C

2. Relative humidity: ∠85%RH

3. There is no strong vibration and no strong electromagnetic field in the surroundings

4. There is no high concentration of dust and corrosive substances around

5. No direct sunlight or other direct radiation from heat sources

6. There is no strong air flow around, and when the surrounding air needs to be forced to flow, the air flow should not be blown directly on the box

7. The test chamber should be placed smoothly and maintained at the level

8. The installation site is well ventilated

9. Good grounding

4: Structure, material and characteristics

1. The inner shell of the test chamber is made of 3042B stainless steel

2. The shell of the test chamber is a high-quality stainless steel plate

3. The dust blowing motor is a special stainless steel shell, with strong sealing, low noise and high wind speed

4. The inner shell of the box is funnel-shaped, the vibration cycle is adjustable, and the dust flies freely and falls and gathers next to the blowing hole

5. There is an observation window on the door of the box, which can observe the state of the sample in the box when the dust blowing stops

5: Control system

1. Equipped with West German original programmable controller

2. The parameter setting is simple, no need to enter the program function table, you can directly enter the parameter function table to modify

3. The total time of the test, the intermittent time of dust blowing and the cycle of dust blowing can be controlled

4. The temperature adopts RKCDC type temperature controller, which can be adjusted at RT+5~60°C to prevent the test dust in the box from being affected by moisture in the air and getting wet

5. The test tank and the control cabinet are integrated, and the casters are installed at the bottom, and the other systems are hidden, which is beautiful and generous

5. Safety protection device

1. Temperature protection in the box to prevent the temperature control from running out of control and affecting the test

2. Three-phase voltage underphase, phase sequence protection to prevent the dust blowing fan from working in reverse

6. Meet the standards

1. IEC-529 dustproof test method

2. GB4208-93 dustproof test method

3. GB2423.37-89 dustproof test method

4. GJB150.12 dustproof test method
