　　一、通風管道在安裝時的注意事項：

　　I. Notices for Ventilation Pipeline Installation:

　　(1)當風管與風機連接時，應在進出風口處加軟接頭，其軟接頭的斷面尺寸應與風機進出風口一致。軟管接頭一般可采用帆布、人造革等材料，軟管長度不宜小于200，松緊度應適宜，柔性軟管可緩沖風機的振動。

　　(1) When the duct is connected with the fan, the soft joint should be added at the inlet and outlet of the fan. The cross-section size of the soft joint should be the same as that of the inlet and outlet of the fan. The hose joint can generally be made of canvas, artificial leather and other materials. The length of hose should not be less than 200, the tightness should be appropriate, and the flexible hose can cushion the vibration of the fan.

　　(2)當風道與除塵設備、加熱設備等連接前，應待設備安裝完畢后，按實際測繪的圖紙進行預制和安裝。

　　(2) When the air duct is connected with dust removal equipment and heating equipment, it should be prefabricated and installed according to the actual surveying drawings after the installation of the equipment.

　　(3)風道安裝時，進、出風日宜在風道預制時開出洞口，如需在安裝完畢的風道上現開風口，其接口處應嚴密。

　　(3) When the duct is installed, the inlet and outlet days should be opened when the duct is prefabricated. If the outlet is to be found in the installed duct, the interface should be tight.

　　(4)當輸送含凝結水或含濕量較大的氣體時，其水平管道宜設有坡度，并在低點處接排水管。安裝時風道底部不宜出現縱向接縫，對底部有接縫處應進行密封處理。

　　(4) When conveying gas with condensate water or high moisture content, the horizontal pipeline should have a slope and be connected with a drainage pipe at a low point. Longitudinal seams should not appear at the bottom of the duct during installation. Sealing treatment should be carried out at the seams at the bottom.

　　(5)對輸送易燃、易爆氣體的鋼板風道，在風道連接法蘭處應安裝跨接線，并與靜電接地網連接。

　　(5) For steel plate air ducts conveying flammable and explosive gases, a cross connection shall be installed at the flange of the air duct connection and connected with the electrostatic grounding grid.

　　二、通風管道安裝程序：

　　2. Installation procedures for ventilation pipes:

　　(1)風管組裝：當風管較短時，可一次在地面組裝而成，當風管較長時，可視安裝場地的情況，在地面分段組裝。組裝時應盡量調整風道的中心度和水平度，避免風管扭曲或上下起波，左右擺龍，每段風道不宜超過10m.組裝時，墊片應墊平，法蘭螺栓應均勻擰緊，螺母帽均朝向同一方向。

　　(1) Air duct assembly: When the air duct is short, it can be assembled on the ground at one time. When the air duct is long, it can be assembled on the ground in segments according to the situation of the installation site. When assembling, adjust the centrality and levelness of the duct as far as possible to avoid the distortion or upside and downs of the duct, swing dragons from left to right, and each duct should not exceed 10 m. When assembling, gaskets should be padded flat, flange bolts should be tightened evenly, and nuts should be in the same direction.

　　(2)風管就位：風管就位前應檢查全部支架的水乎度和標高、檢查支架的牢固程度，風管就位可采用直接和吊具兩種方法。對風管斷面較小，又位置較低的可采用人工就位方法，只需搭設簡易腳手架即可。當風管斷面較大且管段較長時，可采用滑輪、倒鏈、大繩等方法吊裝。世紀星介紹為了便于風道就位，一般多采用將風道吊在腳手架上，然后再將其抬放在風道支架上的方法。腳手架應沿其風道長度方向搭設，高度和位置應適合施工操作，吊裝順序應先干管后支、立管，吊起時，吊點應牢固，兩吊點應均勻受力。垂直風管可采用人工和大繩輔助就位。調整風管保證垂直度要求。

　　(2) Air duct positioning: Before air duct positioning, the water alignment and elevation of all brackets should be checked, and the firmness of brackets should be checked. Direct and suspension methods can be used for air duct positioning. For the smaller section and lower position of the air duct, the manual positioning method can be adopted, and only simple scaffolding can be set up. When the section of air duct is large and the section is long, pulleys, chains and ropes can be used for hoisting. Century Star introduced that in order to facilitate the placement of the air duct, the method of hanging the air duct on the scaffolding and then lifting it on the air duct bracket is usually adopted. The scaffolding should be erected along the length direction of its air duct, and the height and position should be suitable for construction operation. The lifting sequence should first be trunk pipe, then branch pipe and riser pipe. When lifting, the lifting point should be firm and the two lifting points should be uniformly loaded. Vertical ducts can be positioned with manual and large rope assistance. Adjust the air duct to ensure the verticality requirement.

　　(3)風道調直：就位在支架上的風道，應撥正位置，調整風道橫平豎直，然后再按圖集要求固定。

　　(3) Straightening the air duct: The air duct positioned on the support should be positioned to adjust the horizontal and vertical air duct, and then fixed according to the requirements of the atlas.
