  一、通风管道在安装时的注意事项:

  I. Notices for Ventilation Pipeline Installation:

  (1)当风管与风机连接时,应在进出风口处加软接头,其软接头的断面尺寸应与风机进出风口一致。软管接头一般可采用帆布、人造革等材料,软管长度不宜小于200,松紧度应适宜,柔性软管可缓冲风机的振动。

  (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)当风道与除尘设备、加热设备等连接前,应待设备安装完毕后,按实际测绘的图纸进行预制和安装。

  (3)风道安装时,进、出风日宜在风道预制时开出洞口,如需在安装完毕的风道上现开风口,其接口处应严密。

  (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)当输送含凝结水或含湿量较大的气体时,其水平管道宜设有坡度,并在低点处接排水管。安装时风道底部不宜出现纵向接缝,对底部有接缝处应进行密封处理。

  (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)对输送易燃、易爆气体的钢板风道,在风道连接法兰处应安装跨接线,并与静电接地网连接。

  (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、通风管道安装程序:

  2。 Installation procedures for ventilation pipes:

  (1)风管组装:当风管较短时,可一次在地面组装而成,当风管较长时,可视安装场地的情况,在地面分段组装。组装时应尽量调整风道的中心度和水平度,避免风管扭曲或上下起波,左右摆龙,每段风道不宜超过10m.组装时,垫片应垫平,法兰螺栓应均匀拧紧,螺母帽均朝向同一方向。

三分PK拾  (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.

三分PK拾  (2)风管就位:风管就位前应检查全部支架的水乎度和标高、检查支架的牢固程度,风管就位可采用直接和吊具两种方法。对风管断面较小,又位置较低的可采用人工就位方法,只需搭设简易脚手架即可。当风管断面较大且管段较长时,可采用滑轮、倒链、大绳等方法吊装。世纪星介绍为了便于风道就位,一般多采用将风道吊在脚手架上,然后再将其抬放在风道支架上的方法。脚手架应沿其风道长度方向搭设,高度和位置应适合施工操作,吊装顺序应先干管后支、立管,吊起时,吊点应牢固,两吊点应均匀受力。垂直风管可采用人工和大绳辅助就位。调整风管保证垂直度要求。

  (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)风道调直:就位在支架上的风道,应拨正位置,调整风道横平竖直,然后再按图集要求固定。

  (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。
