Constant air pressure sand and dust test chamber is affordable in China

With the rapid development of modern industrial technology, the application fields of electrical and electronic products are becoming increasingly broad, and the environmental conditions they experience are becoming more and more complex and diverse. Only by reasonably specifying the environmental conditions of the product and correctly selecting the environmental protection measures for the product can the product be protected from damage during storage and transportation and be safe and reliable during use. Therefore, artificial simulated environment testing of electrical and electronic products is an indispensable and important link to ensure their high quality. Artificial simulated environmental tests are scientific summaries of actual environmental impacts and have the characteristics of typification, standardization, ease of use, and ease of comparison. The diversification of environmental conditions and the importance of environmental testing also put forward more stringent requirements for environmental testing equipment.
According to national standards.-Test: Constant air pressure sand and dust test method-Enclosure protection level (code).-Rotating motor enclosure protection level-Motor vehicle retro-reflector. General safety requirements and testing of lamps, - and a series of related A series of corresponding environmental test equipment have been developed based on the standards for enclosure protection levels. The equipment is reasonably designed, simple to operate and easy to maintain, and all indicators are in line with national standards. This series of dust-proof test equipment is used to test the shell sealing performance of products. It is mainly used for tests at two levels specified in the shell protection level standards.

3. Test box structure
. This dust-proof test equipment is made of high-quality materials for processing and forming. The surface of the shell and the outer wall of the door are made of high-quality steel plates with electrostatically colored surfaces. The plastic spray treatment is beautiful and smooth. The color combination is coordinated and the arc-shaped design has smooth and natural lines.
. The inner tank material is made of high-quality stainless steel plates and is designed to be a closed space where samples can be placed for shell sealing tests during operation. The indoor sample racks and other accessories are made of stainless steel plates and are reasonably designed and durable.
. There is an oversized observation window on the door of the box. There is a lighting device in the box to clearly observe the conditions of the indoor test and the sample is clearly visible during the test. The door is tightly sealed with double-layer silicone sealing strips and is easy to open and close. The box is specially designed with a device for placing samples.
. The equipment has vertical circulation of airflow carrying talcum powder as dust. The dust is blown into the circulating air duct by the fan at the bottom of the funnel and then evenly diffused by the air outlet air guide plate on the upper part of the equipment. With the help of the circulating air flow, the dust can be evenly suspended in the test chamber. The amount of talcum powder is based on the number of uses per cubic meter of the volume in the test chamber. No more than times. Stainless steel impeller for driving dust, air outlet air guide plate
. There is a dust replaceable device at the bottom of the equipment, which can easily replace the used dust.
. In order to ensure that dust does not stick to the box wall and condense, a special device is installed to ensure that dust does not stick to the box wall and condense. The working time of the device is adjustable and can work alternately automatically. . On the premise that the equipment complies with national standards and has stable performance in all aspects, it is more practical and easy to control. And the equipment is easy to install, simple to operate and basically does not require daily maintenance.
