Overview
HZAOC SC-020 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, with dust-carrying vertical circulation air flow, the test dust can be recycled, and the wind speed is adjusted through the centrifugal fan and frequency converter to form a closed vertical dust blowing circulation system to disperse the dust evenly.
Features
1. Adopt large-diameter stainless steel centrifugal wind wheel plus dust Stir and drying mechanism to effectively absorb dust.
2. Adopt a miniature eccentric motor to achieve efficient dust shaking.
3. The bottom of the box funnel is equipped with a dust cleaning discharge port, which is convenient for dust cleaning and replacement.
4. Equipped with a bright and clear large observation window and equipped with lighting, it is convenient to observe the dust concentration and dust volume in the box.
5. Adopt a new generation of Xinjie PLC all-in-one controller, the man-machine interface is integrated with PLC, the operation is simple, and the system is stable and reliable.
6. Equipped with a dust drying heating device, which can dry humid dust to ensure the accuracy of test data.
7. Equipped with safety functions such as power component anti-overload protection, equipment phase loss and phase sequence protection.
Principle
Dust test chamber generates airflow through a single high-power low-noise centrifugal fan, and uses a frequency converter to adjust the wind speed to form a dust-carrying vertical circulation system. The air duct is made of stainless steel plate, and the bottom is connected to the tapered hopper interface. The trend of the fan in and out is directly connected to the air duct, and the diffusion port at the top of the studio is connected to the studio body to form an "O" type closed vertical dust blowing cycle, so that the airflow flows smoothly and the dust is dispersed evenly to the greatest extent.
Applications
Shell sealing performance test, IP5X and IP6X Protection Rating test
Standards
GB/T4208-93、GB/T4208-93
Steps
1. Operate the controller in the order indicated on the display.
2. Adjust the variable frequency governor to control the wind speed as required.
3. If the dust is wet, open the heating button in the control screen to start the dust drying device.
4. Turn off the heating button after drying to ensure that the test is carried out normally.
Notice
• Use the drying device in time when dust is found to be wet during the test.
• Pay attention to the safety protection function of the equipment, and check the alarm screen of the controller when the protection action is taken.
• The dust drying process does not affect the test, but it is necessary to ensure the dust concentration and the accuracy of the test data.
