Many industries have relevant standards that require products to pass dust tests. For instance, the automotive industry demands that automotive parts maintain good performance in dusty conditions to ensure driving safety; the electronics industry requires that products do not malfunction in dusty environments to guarantee their stability and reliability. By undergoing tests in dust chambers, products can meet these industry standards and obtain market access qualifications.
3、Research and Development and Improvement
During the process of new product research and development, sand and dust test chambers can help engineers understand the performance variation patterns of products under different sand and dust conditions, providing a basis for the optimization of product design. By simulating sand and dust environments of varying degrees, testing the product's tolerance, R&D personnel can make targeted improvements to the product structure and materials, enhancing the product's resistance to sand and dust.
sand dust test chamber Selection Guide
Points to note when choosing a sand and dust test chamber
1、The sealing property of the test chamber should be good.
2、The dust blowing test chamber should be equipped with a sand separator to enable the fan to circulate the air repeatedly without sand.
3、The air filled with dust inside the dust blowing test chamber is allowed to flow approximately in a laminar manner between the test samples.
4、The cross-sectional area of the working space of the test chamber should be more than twice the cross-sectional area of the test sample, and the effective volume should be more than 3.3 times the volume of the test sample.
5、The sand and dust test chamber should be equipped with instruments capable of monitoring and controlling the sand and dust concentration, wind speed, temperature and relative humidity, as well as other auxiliary devices.
Installation Guide for sand dust test chamber
1、Installation Site Selection
1.1、Space Requirements: The sand and dust test chamber should be installed in a spacious and well-ventilated indoor environment with no obstacles around to ensure that the chamber can be opened and closed normally and facilitate operation and maintenance. Generally, at least 500mm of space should be reserved on all sides of the test chamber and 1000mm above it to ensure smooth air circulation and heat dissipation.
1.2、Floor Requirements: The installation site floor should be flat and solid, capable of supporting the weight of the test chamber. It is recommended to lay rubber or anti-vibration pads on the floor to reduce the impact of vibrations generated during equipment operation on the surrounding environment.
1.3、Temperature and Humidity Requirements: The ambient temperature of the installation site should be maintained between 5℃ and 35℃, and the relative humidity should not exceed 85%. Avoid installing the test chamber in direct sunlight or near heat or cold sources to prevent affecting the normal operation of the equipment and the accuracy of test results.
1.4、Ventilation Requirements: The installation site should have good ventilation conditions to ensure that the sand and dust and heat generated by the test chamber during operation can be promptly discharged outdoors. Exhaust fans or ventilation ducts can be installed near the test chamber to ensure smooth air circulation.
2、Installation Preparation Work
2.1、Check the equipment: Before installation, conduct a comprehensive inspection of the sand and dust test chamber to ensure that there is no damage to the appearance of the equipment and all components are complete. Check whether the power cord, air source pipe and other connections of the equipment are firm. If there is any looseness, it should be dealt with in time.
2.2、Prepare tools and materials: The tools and materials required for installation include wrenches, screwdrivers, levels, expansion bolts, anchor bolts, etc. Ensure that all tools are complete and in good condition, and prepare necessary protective equipment such as gloves and safety glasses.
2.3、Determine the installation location: According to the requirements of the installation site, select an appropriate installation location and mark the installation position of the test chamber on the ground. Use a level to check the levelness of the installation location. If there is any deviation, it should be adjusted in time.
3、Installation Steps
3.1、Place the sand and dust test chamber: Carefully place the sand and dust test chamber on the pre-marked installation position to ensure the equipment is stable. Use a level to check the levelness of the test chamber again. If it is not level, adjust the height of the anchor bolts to make the equipment level.
3.2、Fix the test chamber: Use expansion bolts or anchor bolts to fix the test chamber to the ground or foundation to prevent the equipment from shaking or moving during operation. During the fixing process, ensure that the bolts are tightened and the connection is firm.
3.3、Connect power and air source: According to the electrical and air source requirements of the test chamber, connect the power cord and air source pipe to the corresponding interfaces of the test chamber. When connecting the power cord, pay attention to whether the power voltage and frequency meet the equipment requirements and ensure good grounding. When connecting the air source pipe, check whether the air source pressure is within the specified range and ensure that the air pipe is firmly connected without leakage.
3.4、Install the sand and dust circulation system: According to the installation manual of the equipment, install and connect the various components of the sand and dust circulation system (such as fans, filters, sand and dust collectors, etc.). Ensure that the sand and dust circulation system is installed correctly, the pipelines are tightly connected, and there is no sand leakage.
3.5、Check the sealing: After installation, check the sealing of the test chamber body. Check whether the sealing strips of the door, observation window, etc. are intact. If damaged, replace them in time. Close the test chamber door and observation window, and check for any sand and dust leakage.
4、Installation Precautions
4.1、Safety First: During the installation process, strictly follow the safety operation procedures and wear protective gear to prevent accidents. Pay special attention to preventing electric shock and gas leakage when connecting power and gas sources.
4.2、Professional Installation: The installation of sand and dust test chambers requires professional technicians to operate. Non-professionals are not allowed to install or debug the equipment without authorization. If any problems arise during installation, contact the equipment manufacturer or supplier promptly for technical support.
4.3、Regular Maintenance: After installation, clean, inspect and maintain the test chamber regularly in accordance with the equipment's maintenance requirements to ensure its normal operation and service life. At the same time, establish an equipment file to record information such as installation, commissioning and maintenance.
