IEC 60529 GB2423.37 Dust Chamber For Testing Dust Resistance Of Electronics, Auto Components

Model and Technical Parameters

Model: KP-SC6K1000-CS

Studio size (mm): 1000 * 1000 * 1000 (depth × width × height)

External sizes (mm): 3000X7000X2200 (depth X width X height)

Structure and Material

Design principles

a tapered funnel design, the bottom is dust collection port, at the dust collection port (right) to install high-pressure turbine axial flow fan suction port, the dust will fall from dust filling port to the high-pressure blower by compressed air, The dust is blown into the inner box by high wind speed, and the wind that blows past is circulated back from the air duct to start the cycle again and again. Dust storage box with heating and drying function.

Material

1. Inner material: sus304 stainless steel

2. Outer material: stainless steel

3. Chamber door with a large observation window

4. Unique duct design, to ensure the concentration of laminar flow

5. Basic structure: pre-blowing dust box, chamber, dust collection port, dust box, circulating air duct, vacuum system, dust storage tank, flow valve, heating system, backflow vane, sample carousel,protective screen,concentration meter back to dust and other components.

Technical Parameters

1. Fine sand: ＞150um

2. Coarse sand:＜890um

3. Inside the box and pipe, the dust concentration is 10G / m³ ± 1

4. Airflow speed: 18m / s ± 1.5 (adjustable)

5. Quartz powder dosage: 6kg / m³ (70% quartz sand, 15% chalk, 15% kaolin) 6. Duct width: 800MM

Control System

1. PLC and touch screen intelligent control system (Teelong brand)

2. PT100 test sensor

3. Sand and dust concentration meter

4. Anemometer (hand-held) to adjust the wind speed before testing.

5. Instrument over-temperature protection

6. Power phase loss protection

7. Leakage circuit breaker

8. Power: AC380 V 50Hz

9. Door: tempered glass door

10. Vacuum pump 60-600L / H

11. Pressure regulating valve, nozzle, pressure regulator

Controller: Adopt programmable controller (this controller has many kinds of arbitrarily setting control functions as below)

a. blowing dust time (stop, blow) h / m / s adjustable

b. Cycle time: adjustable

c. Default test time: 0s ~ 999h99m99s adjustable

d. Power on: off - on - off

Metal mesh size: nominal diameter of 50um, line spacing between 75um and 150um nominal

Dryer: plastic centrifugal fan

Note: The chamber can meet the ISO20653-6K standard, mainly used for household appliances, low voltage electrical appliances, automotive, motorcycle parts shell protection level test requirements. (with talc 5KG)
