Pre-conditioned Air Duct to the uneven inner diameter of the duct during operation, resulting in narrowing or widening. This change can cause changes in the air flow state inside the duct, leading to increased wind resistance and uneven pressure distribution, which may result in serious consequences such as decreased fan performance and bearing overload. Therefore, in the process of designing the air duct, the inner diameter of the air duct should be determined based on parameters such as air volume, static pressure, and dynamic pressure of the fan, referring to relevant standards, and calculated and verified to ensure that the size of the air duct is appropriate.
The application range of wind tunnel diameter reduction is quite extensive, mainly reflected in the following aspects:
Industrial facilities: In blast furnace systems such as steel mills, variable diameter air ducts are used to adjust the airflow of the air supply system to optimize the efficiency of the blast furnace.
Commercial facilities: In shopping centers and office buildings, variable diameter air ducts help adjust the airflow of the ventilation system, ensuring comfortable and effective air quality.
Environmental control: In places such as laboratories and cleanrooms that require precise environmental control, variable diameter air ducts are used to adjust the speed and direction of airflow to meet specific environmental requirements.
In addition, there are some specialized variable diameter air duct products on the market, such as Guohua Intelligent Mining Variable Diameter Air Ducts, which are designed to be easy to maintain, convenient to store, and have good compressive strength and a wide range of applicable environments.
Overall, the variable diameter of air ducts has important applications in multiple fields, which can effectively improve and optimize airflow to meet the needs of different environments and occasions. However, during use, it is also necessary to pay attention to the potential issues that may arise from the variable diameter of the air duct, such as increasing the strength of the pressure bearing shell and setting up appropriate detection systems to ensure the safe operation of the fan.
