Rationalization of pipeline design: In pipeline design, the control of wind resistance and pressure loss should be fully considered, and the occurrence of wind resistance and pressure loss should be reduced by selecting reasonable parameters such as pipeline material, pipeline diameter, and pipeline length. For example, using smooth inner wall materials, selecting appropriate diameters to reduce frictional resistance, controlling pipeline length and number of bends to reduce resistance and pressure loss.
Reducing elbow angle and curvature radius: Elbows and curvature are common sources of resistance in ventilation ducts. By reducing elbow angle and curvature radius, wind resistance and pressure loss can be effectively reduced. Generally speaking, a 90 degree elbow produces greater resistance than a 45 degree elbow, so it is advisable to minimize the use of 90 degree elbows and choose smaller angle elbows.
Control the pipeline connection method: The pipeline connection point is a place where resistance and pressure loss are prone to occur. Therefore, in the processing of ventilation pipelines, it is necessary to choose an appropriate connection method to reduce resistance and pressure loss. Common pipeline connection methods include flange connection, threaded connection, and slot connection. Choosing the appropriate connection method can ensure tight connection, reduce air leakage, and thus reduce resistance and pressure loss.
Regular cleaning and maintenance: Impurities such as dust and dirt can accumulate in ventilation ducts, which can increase wind resistance and pressure loss. Therefore, after the processing of the ventilation pipeline, it is necessary to regularly clean and maintain the pipeline to ensure the cleanliness of the inner wall of the pipeline, in order to reduce wind resistance and pressure loss.
Use streamlined design: Streamlined design can reduce resistance and pressure loss. In the processing of ventilation ducts, streamlined design can be adopted, such as using streamlined elbows that overcome double bends to reduce resistance and pressure loss.
Reasonable selection of fans: Fans are the core equipment of the ventilation system, and selecting a reasonable fan can effectively reduce wind resistance and pressure loss. In the processing of ventilation ducts, appropriate fan types and specifications should be selected according to actual needs to ensure that the air volume and pressure of the fan meet the requirements of the system, in order to greatly reduce wind resistance and pressure loss.
Increase the cross-sectional area and ventilation capacity of the air duct: In the processing of ventilation ducts, the cross-sectional area and ventilation capacity of the air duct can be appropriately increased to reduce wind resistance and pressure loss. For example, adding parallel air ducts in a ventilation system can divert airflow and reduce the wind resistance and pressure loss of a single duct.
Regular inspection and adjustment: After the processing of the ventilation pipeline is completed, the ventilation system should be regularly inspected and adjusted to ensure that the wind resistance and pressure loss are within a reasonable range. By measuring parameters such as air pressure and wind speed in the air duct, as well as observing the operation of the ventilation system, problems of wind resistance and pressure loss can be identified and resolved in a timely manner.
