Sales of sand and dust test chambers in Taizhou, China are considerable

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 stipulating the environmental conditions of the product and correctly selecting the environmental protection measures for the product can we ensure that the product is protected from damage during storage and transportation and is 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 environment tests are scientific summaries of actual environmental impacts and are typical, standardized, easy to use, and easy to compare. The diversification of environmental conditions and the importance of environmental testing also put forward more stringent requirements for environmental testing equipment.
According to national standard B/.3-Test: Constant air pressure sand and dust test method, -Enclosure protection level (code) B/Rotating motor enclosure protection level, -Motor vehicle retro-reflector B/Lamps general safety requirements and tests , B/- and other related shell protection grade standards, a series of corresponding environmental test equipment have been developed. The equipment is reasonably designed, simple to operate, easy to maintain, and all indicators are in line with national standards. This series of dustproof test equipment is used to test the shell sealing performance of products, and is mainly used for tests of the two levels specified in the shell protection level standards.
2. Main technical specifications and parameters of the equipment
. Model studio size:

()
()
()
()
. The time setting range is adjustable in hours
3. The nominal wire diameter of the dust used to pass through the metal screen is: , and the nominal spacing between the wires is
. Air flow speed: no Exceed
. Continuous and periodic selection of time setting
. Sand and dust concentration:
. Test dust: dry talcum powder, Portland cement, flue dust, etc.
. Vibration time: ~ Adjustable
3. Test box structure
. This dust-proof test equipment is made of high-quality materials. The surface of the shell and the outer wall of the door are made of high-quality steel plates. The surface is treated with electrostatic color spraying, which is beautiful. smooth. Coordinated color matching, arc-shaped design, smooth and natural lines.
. The inner tank material is made of high-quality stainless steel plate, and is designed to be a closed space during operation, where samples can be placed for shell sealing tests. The indoor sample racks and other accessories are made of stainless steel plates, with reasonable design and durability.
3. There is a large observation window on the door of the box, and there is a lighting device inside the box. During the test, the conditions of the indoor test can be clearly observed, and the sample is clearly visible. The door adopts double-layer silicone sealing strip, which is tightly sealed and easy to open and close. The box is specially designed with a device for placing samples.
. The equipment has a vertical circulation airflow carrying dust, with talcum 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 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 calculated per cubic meter of the test chamber. Volume, use no more than once. Stainless steel impeller for driving dust and air outlet guide plate
. There is a dust replacement 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. 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 be automatically alternated. Work. . 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. Moreover, the equipment is easy to install, simple to operate, and basically does not require daily maintenance.
