Equipment Overview

Test purpose: This test chamber is used for mechanical, electrical, electronic, electrochemical, and electromechanical equipment. Evaluate the resistance, storage and operation of these devices to exposure to dry sand or dust-laden atmospheres. Used for product sealing performance testing and reliability testing.

Chamber features:

1. The vibration adopts pneumatic vibration mode, and the amplitude can be adjusted stepless;

2. Equipped with a frequency converter, the running speed of the fan can be adjusted by frequency conversion;

3. The sample pumping speed and pressure can be adjusted independently, and the pumping pressure is stable;

4. Equipped with an electronic temperature and humidity meter, which can be directly displayed on the touch screen;

5. The bottom funnel is equipped with a ball valve switch for easy dust replacement;

6. The wall of the test chamber is equipped with an air dust filter assembly, and the atmospheric pressure of the inner and outer chambers is balanced;

7. The program is easy to operate. In addition, the sample power-on preheating function is added. For example, when testing lamps, the lamps are required to be powered on and preheated to a stable state before dust testing. After the warm-up time is complete, the device will automatically start the dust test. In this way, the luminaire test can be completed directly in the dust chamber at one time.

8. Chamber structure: the door opening is unobstructed (1500X1000mm), and the door is fully open, which is convenient for placing large and heavy samples in the chamber.

Safety protection: fault alarm and cause, processing prompt function, automatic shutdown after fault alarm; leakage protection, short circuit protection, fan motor overheating, overall equipment phase loss/reverse phase, overall equipment timing protection.

Power supply: AC 380V 50HZ 4KW; one compressed air source interface, Φ8mm air tube.

Chamber Structure:

1. It is designed as a conical funnel with a dust collection port and a dust blowing port at the bottom. Install a high-pressure turbine circulation fan at the dust blowing port to send the dust from the funnel to the top of the inner chamber. The dust is blown down naturally from the top vertically. When the dust falls on the side wall of the funnel, the dust is recycled to the dust blowing port by the vibrating device, so that the cycle starts again and again.

2. Inner chamber material: stainless steel plate;

3. Outer chamber material: cold-rolled steel plate + baking paint/spray plastic;

4. Two observation windows;

5. Dust scraper: it is convenient to observe the test situation;

6. Lighting lamp: one LED lighting is installed inside, which is convenient for observing the test situation;

7. Test hole: Ø100mm;

8. The load of the compartment bracket: 100KG.
