Environmental Testing Walk-in Large Sand And Dust Test Chamber 19.8m³
Complied Standards & Clauses
IEC 60068-2-68: 2001 Environmental testing- Part 2: Tests- Test L Dust and sand.
Product Overview
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).
Technical Parameters
| Working room temperature | RT+10℃～+70℃ |
| Product vacuum degree | ≤60KPa |
| Inner chamber dimensions | 3000*2000*3300mm (W*D*H) |
| Outer chamber dimensions | About 3200*27000*4500 mm(W*D*H) |
| Working humidity | ≤75%R.H |
| Test sample specifications | Charging stations, electrical cabinets, energy storage cabinets The size range is not larger than 2000*1500*2500m (W*D*H) Weight 1000kg |
| Dust composition | Talcum powder |
| Dust concentration | 2～4kg/m3 |
| Composition of dust particles | Dry talcum powder that can pass through a square hole sieve with a mesh size of 75µm and a wire mesh diameter of 50µm |
| Sand and dust air circulation device | Circulation air ducts and high-power mixed-flow ventilators have an air extraction volume of 80 times the tested shell volume, and the air extraction speed does not exceed 60 times the shell volume per hour. And the speed of the airflow can make the dust evenly distributed in the test chamber. The airflow in the test chamber is mainly top-down vertical airflow rather than laminar flow. The pressure gauge has a calibration interface. |
| Dust test device | a) Set up 1 funnel at each of the 4 corners of the test chamber and 2 funnels in the middle (a total of about 6 pieces, subject to actual use), and a metal dust filter is installed on the upper surface of the funnel. b) A set of rotating devices is designed between the lower part of the loading platform and the bottom plate of the warehouse, and the dust is swept into the funnels at the four corners through dust brushes. c) A high-power mixed-flow fan is installed at the bottom of the funnel to send the dust to the working room through the circulating air duct for settlement. |
