Test box structure
1. The sand and dust test chamber is made of high-quality materials processed and formed. The surface of the shell and the outer wall of the door are made of high-quality steel plates, and the surface is treated with electrostatic color spraying, which is beautiful and smooth. Coordinated color matching, curved design, smooth and natural lines.
2. The inner liner material is made of high-quality stainless steel plate, designed to be a sealed space during operation, where samples can be placed for shell sealing tests. The indoor sample rack and other accessories are made of stainless steel plates, with a reasonable design and durability.
3. There is a large observation window on the box door, and there is a lighting device inside the box. During the test, the indoor test conditions can be clearly observed, and the sample is clearly visible. The box door adopts double-layer silicone sealing strips, which are tightly sealed and easy to open and close. The box is specially designed with a device for placing samples.
4. The equipment has a vertical circulation airflow carrying dust, with talc powder as the dust. The dust is blown into the circulating air duct through the fan at the bottom of the funnel, and then evenly diffused by the air outlet guide plate on the upper part of the equipment. With the help of the circulating airflow, the dust can be uniformly suspended in the test chamber. The amount of talc powder used is 2kg per cubic meter of the volume in the test chamber, and the number of uses does not exceed 20 times. Stainless steel impeller and air outlet guide plate for driving dust:
5. There is a dust replaceable device at the bottom of the equipment, which can easily replace 100% of the used dust.
In order to ensure that dust does not stick to the box wall and condense, a special device has been installed. The device can ensure that dust does not stick to the box wall and condense. The working time of the device is adjustable and can automatically alternate between operations.
On the premise of complying with national standards and ensuring stable performance in all aspects, the equipment is more practical and easy to control. Moreover, the device has the characteristics of easy installation and simple operation.

This device is mainly used for testing products such as automobiles, lighting fixtures, low-voltage electrical appliances, communications, motors, instruments, and household appliances. During storage, transportation, and use, it is often affected by sand and dust environments, especially for automobiles, lighting fixtures, and low-voltage electrical appliances. This equipment is a testing device that uses artificial simulation of sand and dust environment to test the dust prevention ability of the test sample, meeting the testing requirements of IP protection levels IP5X and IP6X. Testing is used to determine whether the performance of a product meets the requirements, which is then used for product design, improvement, identification, and factory inspection.
