Overview
HZAOC SC-010 Dust test chamber simulates the natural wind and sand climate on the product Destructiveness, suitable for detecting the sealing performance of the product shell, mainly used for the test of IP5X and IP6X two grades specified in the shell protection class standard. The equipment is made of stainless steel plate air duct to form a closed vertical dust blowing circulation system, so that the airflow flows smoothly and the dust is dispersed evenly to the greatest extent, equipped with high-power low-noise centrifugal fan and frequency converter to adjust the wind speed.
Features
1. Using large diameter stainless steel centrifugal wind wheel plus dust Stir and drying mechanism to effectively absorb dust; 2. Using micro eccentric wheel motor to achieve effective dust shaking; 3. The bottom of the box funnel is equipped with dust cleaning and discharge port, which is convenient for dust cleaning and replacement; 4. Equipped with bright and clear large observation window and equipped with lighting, it is convenient to observe the dust concentration and dust amount in the box; 5. Adopting a new generation of Xinjie PLC integrated machine controller, the system is stable and reliable, and supports man-machine dialogue input; 6. Equipped with dust drying heating device, drying humid dust without affecting the test process; 7. It is equipped with power source anti-overload protection, equipment phase loss and phase sequence protection, and the controller has alarm screen prompts.
Principle
Dust test chamber simulates the wind and sand environment through the air flow that carries dust vertically circulating. The air duct is made of imported stainless steel plate, and the bottom is connected with the tapered hopper interface. The trend of the fan in and out is directly connected with the air duct. The top diffusion port of the studio is connected to the studio body to form an "O" type closed vertical dust blowing circulation system, so that the air flow flows smoothly and the dust is dispersed evenly to the greatest extent. A single high-power and low-noise centrifugal fan is used to adjust the wind speed through the frequency converter to ensure that the test dust is recycled.
Applications
Test product shell sealing performance, shell Protection Rating test
Standards
GB/T4208-93、GB/T4208-93
Steps
1. Operate the man-machine dialogue input in the order indicated by the controller display screen; 2. Adjust the variable frequency governor to adjust the wind speed as needed; 3. When the dust is found to be humid during the test, open the heating button in the control screen to start the dust drying device; 4. Turn off the heating button after the dust is dried; 5. Observe the dust concentration and dust amount in the box.
Notice
• Ensure that the equipment is connected correctly before the test to avoid phase loss and phase sequence problems; • Pay attention to the use of the heating device when drying the dust, and turn it off in time after drying; • Regularly clean the dust discharge port to keep the equipment clean; • Follow the controller alarm prompt during operation, and deal with the protection action in time.
