Rubber Air Duct Industry knowledge

Factors of airflow efficiency considered in the design of Rubber Air Duct
1. Fluid dynamics optimization
Inner wall smoothness: The inner wall of the Rubber Air Duct is specially treated to reduce friction loss during fluid flow. The smooth inner wall can reduce airflow resistance and improve airflow efficiency.
Streamlined design: The shape of the Rubber Air Duct is designed to be streamlined to reduce the vortex of airflow at turns and joints, thereby improving the continuity and efficiency of airflow.
2. Material selection
Elasticity and pressure resistance: High-quality rubber materials are used to ensure good elasticity and shape stability under high temperature and high pressure conditions, so as not to affect the airflow path.
Chemical resistance: Materials with good tolerance to various chemicals (such as oil smoke, gasoline, etc.) are selected to ensure the durability and smooth airflow of the Rubber Air Duct in the actual working environment.
3. Appropriate diameter and length
Diameter design: According to the requirements of air flow, the diameter of the Rubber Air Duct is reasonably designed to avoid excessive airflow resistance due to too small a diameter, or unstable airflow due to too large a diameter.
Minimize length: Try to shorten the length of the duct to reduce the loss of airflow during transportation, while avoiding unnecessary joints and bends.
4. Joint and connection design
Seamless connection: The connection between the Rubber Air Duct and other components is designed as a seamless joint to reduce the interference of airflow at the joint.
Easy to install: The design takes into account the convenience of installation, ensuring that the connection between the Rubber Air Duct and the equipment is firm and not easy to leak, maintaining the stability of airflow.
5. Temperature resistance
High temperature design: For engines and other high temperature environments, high temperature resistant rubber materials are selected to ensure that they can still maintain good shape and performance at high temperatures and avoid airflow loss caused by thermal expansion.
6. Pressure test
Comprehensive testing: During the design stage, Ningbo Heyuan Auto Parts Co., Ltd. will conduct a series of airflow and pressure tests to ensure that the performance of the duct under various conditions meets the expected standards.
