3000L Dust Chamber Test Device To Verify Protection Against Dust

3000L Dust Chamber - Test Device To Verify Protection Against Dust

The sand and dust test chamber is designed and manufactured according to IEC60529-2001 < Degrees of protection provided by enclosure (IP code)> Fig 2, IEC60068-2-68 and etc. It artificially simulates the dust environment to test the dust-proof ability of the test samples.

The test device is suitable for electrical products’ sand and dust test of first characteristic numeral 5 and 6 (IP5X and IP6X).    Ingress Protection Test Equipment

The chamber can provide a non-laminar flow of dust-loaded vertically circulating air, can be timed controlled; also be equipped with a vacuum pump which can vacuum the test sample, the exhaust volume and pressure can be adjusted; in addition, the inside chamber is configured with a airflow temperature control device, to ensure that the test is under standard environmental conditions.           Ingress Protection Test Equipment

According to the standard requirements, this test chamber uses artificial simulated dust environment to test the dust-proof ability of the sample. The detailed requirements and qualification criteria should be in accordance with IEC60529-2001, IEC60068-2-68 or product standards.

                                                           Ingress Protection Test Equipment

Main parameters:

1. Working size (mm): 1500*2000*1000(D*W*H)
2. Basic design principles: A conical funnel is designed. There are dust collection port and dust extraction port at the bottom. A high-pressure turbine circulating fan is installed at the dust suction port to send the extracted dust to the top of the inner chamber, and then the dust is blown down vertically from the top, so as to start the cycle.
3. Inner material: SUS304B stainless steel plate
4. External material: A3 electrostatic spraying
5. large observation window in the middle of the door
6. The unique air duct design ensures the concentration of laminar air flow in the box
7. Basic structure: pretreatment box, test box, suction port, dust collecting box, circulating dust blowing device, vacuum system, dust storage tank, flow valve, heating system, backflow blade, sample turntable, protective plug net, dust return pipe of concentration meter, etc.
8. Sand and dust concentration in the chamber and pipe is 2kg/m³
9. Air flow speed: ≤2m/s(adjustable)
10. Test sand (or talc) dosage: 2kg ~ 4kg / m³
11. PLC and touch screen intelligent control system                            Ingress Protection Test Equipment
12. PT100 test sensor
13. Instrument over temperature protection function
14. Phase loss protection of power supply
15. Leakage circuit breaker
16. Power supply: AC380 V, 60 Hz, 3.5KW
17. Door: tempered glass door
18. Vacuum pump 60~600L/H
19. Pressure regulating valve, suction nozzle and pressure regulating three piece set
20. Controller: programmable controller (this controller has the following functions of arbitrary setting)

1. Dust blowing time (stop, blow) m/s, adjustable
2. Cycle period: arbitrarily adjustable
3. Preset test time: 0s ~ 9999m59s, adjustable                                         Ingress Protection Test Equipment
4. Power on: off-on-off

21. Square-meshed sieve: nominal wire diameter is 50μm, nominal width of a gap between wires is 75μm
22. Blower: all plastic centrifugal fan
