The walk-in dust test chamber is a professional equipment used to simulate a dust environment, and its specification requirements are essential for testing the sand and dust resistance of products. The following are the specification requirements for the walk-in sand and dust test chamber:
1. Equipment performance: The sand and dust test chamber should have excellent performance and be able to accurately control temperature, humidity and sand and dust concentration. At the same time, the equipment should also be well sealed to avoid external interference in the environment inside the test chamber.
2. Temperature range: In order to ensure the accuracy of the test, the temperature control range of the equipment should be between -25 and 50. The temperature fluctuation should be 05℃。
3. Humidity control: The humidity control range should be between 20% and 90%RH to ensure that the humidity of the test environment meets the standard. At the same time, the humidity fluctuation should be 3%RH.
4. Sand and dust characteristics: The sand and dust test chamber should use dry sand and dust that meets the standard as the test medium. The size, shape, and composition of the dust particles should match the dust in the target application area.
5. Test cycle and cycle length: Determine the reasonable test cycle and cycle length according to the product type and test standard. In general, the test period should not be less than 3 days to fully simulate the movement and deposition of sand and dust in the real environment.
6. Safety protection: The equipment should be equipped with safety protection devices, such as dust covers, safety warning signs, emergency vents, etc., to ensure the safety of operators and equipment.
7. Maintenance: Regularly maintain the equipment to ensure its normal operation. This includes cleaning the filter regularly, checking the tightness, replacing worn parts, etc.
The above are the basic specification requirements of the walk-in sand and dust test chamber, and it needs to be adjusted and improved according to the specific test standards and product types in practical applications. Compliance with these requirements ensures the accuracy and reliability of the test results and provides strong support for the evaluation of the product's sand and dust resistance.
