風(fēng)管的制作重要的就是規(guī)范性，每一個細(xì)節(jié)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(jié)，下面濟南風(fēng)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(fēng)管段制作。風(fēng)管段加工制作時，必須注意邊角位置的漏洞。應(yīng)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(zhì)量檢查。從現(xiàn)場施工考察，角鐵法蘭強度及密封性能，遠(yuǎn)高于共板法蘭。在變風(fēng)量系統(tǒng)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(fēng)管彎頭制作。風(fēng)管彎頭位置應(yīng)按規(guī)范要求設(shè)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(dǎo)流片設(shè)定時，應(yīng)注意合理位置及片數(shù)。變風(fēng)量系統(tǒng)中，風(fēng)量是根據(jù)末端需求而變化。由于風(fēng)管內(nèi)流速、流量會發(fā)生變化，因此彎頭合理的設(shè)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(fēng)管法蘭制作。由于風(fēng)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(yán)格不允許拼接。其強度不能達(dá)到要求，須采用角鋼法蘭或按設(shè)計及規(guī)范要求處理。在變風(fēng)量系統(tǒng)中，由于管道內(nèi)保持較穩(wěn)定的靜壓狀態(tài)，對風(fēng)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(fēng)管三通制作：在VAV變風(fēng)量系統(tǒng)中，由于三通兩側(cè)的風(fēng)量在不同工況下會發(fā)生變化，而隔板或倒流片會嚴(yán)重限制了風(fēng)量的分配，因此三通位置不能加裝導(dǎo)流板或中間加固隔斷。但部件強度必須符合設(shè)計及規(guī)范要求，請采用角鋼法蘭或按設(shè)計及規(guī)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(fēng)管分支管制作：在風(fēng)管系統(tǒng)中（不論是定風(fēng)量或變風(fēng)量），彎頭、三通位置不得直接開分支管，該部位會產(chǎn)生渦流，形成很大的阻力，使各個分支管風(fēng)量難以調(diào)節(jié)，而且會產(chǎn)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(fēng)管制作時需要注意的，每一個方面總結(jié)的還是比較細(xì)致的，所以大家在之后的制作中要注意相應(yīng)的處理，一定要規(guī)范進行，保證之后的使用效果。更多相關(guān)事項就來我們網(wǎng)站http://www.hkcts.com.cn咨詢！
