                風管加工制作期間的5個要點

                風管的制作重要的就是規范性,每一個細節的處理都會影響后的使用,所以我們要注意處理的方法,對于每一個方面的處理下面都進行了簡單的總結,下面濟南風管加工廠為您分析:

                The important thing for the production of air ducts is standardization, and the handling of every detail will affect their subsequent use. Therefore, we need to pay attention to the handling methods. Below is a brief summary of each aspect of the handling. Jinan Air duct Processing Factory will analyze for you:

                1、風管段制作。風管段加工制作時,必須注意邊角位置的漏洞。應該以機械密封為主,輔助以密封膠處理。每段管道加工成型后,需要作質量檢查。從現場施工考察,角鐵法蘭強度及密封性能,遠高于共板法蘭。在變風量系統中,建議使用角鐵法蘭為主。

                1. Production of air duct sections. When processing and manufacturing air duct sections, attention must be paid to the loopholes at the edges and corners. Mechanical sealing should be the main method, supplemented by sealant treatment. After each section of pipeline is processed and formed, quality inspection is required. From on-site construction inspection, the strength and sealing performance of angle iron flanges are much higher than those of common plate flanges. In variable air volume systems, it is recommended to mainly use angle iron flanges.

                2、風管彎頭制作。風管彎頭位置應按規范要求設置倒流片,特別是尺寸較大彎頭,會影響氣流及造成局部噪音。在導流片設定時,應注意合理位置及片數。變風量系統中,風量是根據末端需求而變化。由于風管內流速、流量會發生變化,因此彎頭合理的設置會有利于減少局部阻力。

                2. Production of air duct elbows. The position of the air duct elbow should be equipped with a backflow plate according to the specification requirements, especially for larger elbows, which can affect the airflow and cause local noise. When setting the guide vanes, attention should be paid to the reasonable position and number of vanes. In a variable air volume system, the air volume varies according to the end demand. Due to changes in flow velocity and flow rate inside the air duct, a reasonable setting of the elbow will be beneficial for reducing local resistance.

                3、風管法蘭制作。由于風管采用鋼板法蘭連接,尺寸較大的三通、彎頭等制作需要拼接板材。但是,鋼板法蘭位置嚴格不允許拼接。其強度不能達到要求,須采用角鋼法蘭或按設計及規范要求處理。在變風量系統中,由于管道內保持較穩定的靜壓狀態,對風管強度及密封性能要求較高。

                3. Manufacturing of air duct flanges. Due to the use of steel plate flanges for air ducts, the production of larger tees, elbows, etc. requires splicing of plates. However, the position of the steel plate flange strictly does not allow splicing. Its strength cannot meet the requirements, and angle steel flanges must be used or treated according to the design and specification requirements. In a variable air volume system, due to maintaining a relatively stable static pressure state in the pipeline, there are high requirements for the strength and sealing performance of the air duct.

                4、風管三通制作:在VAV變風量系統中,由于三通兩側的風量在不同工況下會發生變化,而隔板或倒流片會嚴重限制了風量的分配,因此三通位置不能加裝導流板或中間加固隔斷。但部件強度必須符合設計及規范要求,請采用角鋼法蘭或按設計及規范要求加固處理。

                4. Air duct three-way production: In VAV variable air volume systems, due to changes in air volume on both sides of the three-way under different operating conditions, and partitions or backflow sheets severely limiting the distribution of air volume, the three-way position cannot be equipped with guide plates or reinforced partitions in the middle. But the strength of the components must meet the design and specification requirements. Please use angle steel flanges or reinforce according to the design and specification requirements.

                5、風管分支管制作:在風管系統中(不論是定風量或變風量),彎頭、三通位置不得直接開分支管,該部位會產生渦流,形成很大的阻力,使各個分支管風量難以調節,而且會產生局部噪音。

                5. Production of air duct branch pipes: In air duct systems (whether it is a constant or variable air volume), the elbow and tee positions should not directly open the branch pipes. This area will generate eddy currents, creating great resistance, making it difficult to adjust the air volume of each branch pipe, and will generate local noise.

                上述這5個方面是風管制作時需要注意的,每一個方面總結的還是比較細致的,所以大家在之后的制作中要注意相應的處理,一定要規范進行,保證之后的使用效果。更多相關事項就來我們網站http://www.honest-case.com咨詢!

                The above five aspects need to be noted during the production of air ducts, and each aspect is summarized in detail. Therefore, everyone should pay attention to the corresponding treatment in the future production, and must carry out it in a standardized manner to ensure the effectiveness of future use.
