隨著經濟的快速發展，通風管道在生活中的用處越來越大。比如在餐廳，通風設備為消費者提供了良好的就餐環境，讓人們在餐廳吃得開心。下面來看看濟南通風管道設計中應該注意的要點。

With the rapid development of economy, ventilation ducts are more and more useful in life. For example, in restaurants, ventilation equipment provides consumers with a good dining environment, allowing people to eat happily in restaurants. Now let's take a look at the key points that should be paid attention to in the design of Jinan ventilation pipeline.

一、先是應按某系統的某樓層通風管道進行繪制，并注明接口位置。

1、 Firstly, it shall be drawn according to the ventilation pipe of a certain floor of a system, and the interface position shall be indicated.

二、通風管道設計應進行編號，從起點開始編號，起點一般為接口位置，相同斷面規格、相同長度節為同一號碼，除此應按順序編號。以便于組織制作施工。

2、 The design of ventilation ducts shall be numbered from the starting point. The starting point is generally the interface position, and the same section specification and length section are the same number. In addition, they shall be numbered in sequence. To facilitate the organization of fabrication and construction.

三、通風管道設計要標記支吊架位置，支吊架位置間距及材料規格要符后規范要求及工藝規定。

3、 The position of supports and hangers shall be marked in the design of ventilation ducts, and the spacing between supports and hangers and the material specifications shall conform to the following specification requirements and process regulations.

四、制作通風管道設應先考量彎頭與變徑滿足內外表面同心彎管要求、變徑長度要求。

4、 The elbow and reducer shall meet the requirements of inner and outer concentric elbow and reducer length when designing the ventilation duct.

五、通風管道設計應標記起端與彎頭位置、變徑位置、管線所處軸線位置、管底標高。

5、 The position of the starting end and elbow, the reducing position, the axis position of the pipeline and the elevation of the pipe bottom shall be marked in the ventilation pipe design.

此外對充分的準備工作是確保風管安裝質量的前提。在準備凈化風管的制作時，無論是采取工廠集中制作還是現場制作方式，都保證場地的潔凈和封閉，并擁有符合條件的采光和照明條件。除此外，還要對制作好的方管進行看管，盡量避免污染。

In addition, adequate preparation is the premise to ensure the installation quality of air duct. When preparing for the production of purified air duct, whether centralized production in the factory or on-site production is adopted, the site shall be clean and closed, and have qualified lighting and lighting conditions. In addition, the fabricated square tube shall be watched to avoid pollution as much as possible.

預制好的風管，是要做好存放工作，以免受到二次污染。在使用風管前，要注意進行清洗工作，確定板材表面無腐蝕，干燥后不吸塵。關注我們http://www.sjdysx.com，了解更多相關事項！

The prefabricated air duct shall be stored well to avoid secondary pollution. Before using the air duct, pay attention to the cleaning work to ensure that the surface of the plate is free of corrosion and does not absorb dust after drying. Follow us http://www.sjdysx.com , learn more about it!
