　　一般通风管道在安装通风管道时，有一定的方法，如果不按照标准进行安装，将会影响管道在后期的正常使用，下面，我们将简要了解这方面的内容。

　　In general, there are certain methods for the installation of ventilation pipes. If the pipes are not installed according to the standards, it will affect the normal use of the pipes in the later period. Next, we will briefly understand this aspect.

　　1. 管道组装:管道较短时，可一次在地面组装;管道较长时，可根据现场安装情况，在地面分段安装。在安装过程中，应尽量调整管道的水平度，以避免管道变形或上下波动，从左向右摆动。当管道各部分不超过10m时，垫片应平整，法兰螺栓应均匀紧固，螺母盖应向同一方向。

　　1. Pipeline assembly: when the pipeline is short, it can be assembled on the ground at one time; when the pipeline is long, it can be installed on the ground in sections according to the site installation situation. During the installation, the levelness of the pipeline shall be adjusted as much as possible to avoid the deformation or fluctuation of the pipeline, and the pipeline shall swing from left to right. When each part of the pipeline does not exceed 10m, the gasket shall be flat, the flange bolts shall be tightened evenly, and the nut cover shall be in the same direction.

　　2. 管道就位前，应检查各支座的水平度和标高，并检查支座的牢固度。两种方法，直接和吊索，可用于空气管道的地方。风管截面小，且位置低，可采用人工放置方法，只需设置简单的脚手架即可。当风道断面较大、管道断面较长时，可采用滑轮、倒链、大绳等吊装方式。

　　2. Before the pipeline is in place, the levelness and elevation of each support shall be checked, and the firmness of the support shall be checked. Two methods, direct and sling, can be used where air ducts are located. The section of the air duct is small and the position is low, so the manual placement method can be adopted, and only a simple scaffold can be set. When the cross-section of the air duct is large and the cross-section of the pipeline is long, pulley, chain block, rope and other hoisting methods can be used.

　　为了方便管道的位置，一般采用管道挂在支架上，然后将其吊在管道支架上的方法。脚手架应沿长度方向设置风道,高度和位置应该适合施工操作,起重序列应该一干燥管的支持后,垂直管、起重、吊点应公司,两个吊点应统一的力量。垂直风道可安装手动和大绳支撑。调节风道，保证垂直度。

　　In order to facilitate the location of the pipeline, the method of hanging the pipeline on the bracket and then hanging it on the bracket is generally adopted. The scaffold shall be provided with air duct along the length direction, and the height and position shall be suitable for construction operation. The lifting sequence shall be supported by the first drying pipe. The vertical pipe, lifting and lifting points shall be provided by the company, and the two lifting points shall have the same force. The vertical air duct can be installed with manual and rope support. Adjust air duct to ensure verticality.

　　3.通风管道在支架上的位置应调整到正确的位置，然后根据地图集的要求进行固定。

　　3. The position of the ventilation pipe on the support shall be adjusted to the correct position, and then fixed according to the requirements of the atlas.

　　这是通风管道安装的基本过程。另外，在安装过程中应注意以下几点:

　　This is the basic process of ventilation pipe installation. In addition, pay attention to the following points during installation:

1. 风道与风机连接时，应在空气的进出口处加软接头。软接头的截面尺寸应与风机进出口截面尺寸一致。软管接头一般可采用帆布、人造革等材料，软管长度不应小于200，松紧度应适当，柔性软管可缓冲风扇的振动。

2. 
   

　　1. When the air duct is connected with the fan, a soft joint shall be added at the air inlet and outlet. The section size of soft joint shall be consistent with that of fan inlet and outlet. Generally, the hose joint can be made of canvas, artificial leather and other materials. The hose length should not be less than 200. The tightness should be appropriate. The flexible hose can cushion the vibration of the fan.

　　2. 通风管道与除尘设备、加热设备连接前，设备安装完毕后，应按实际测绘图纸预制安装。

　　2. Before connecting the ventilation pipe with the dedusting equipment and heating equipment, and after the equipment is installed, it shall be prefabricated and installed according to the actual mapping drawings.

　　3.管道安装时，应在管道预制当天打开进出口。如果安装后需要打开管道上的出口，则连接应紧密。

　　3. During pipeline installation, the inlet and outlet shall be opened on the day of pipeline prefabrication. If the outlet on the pipe needs to be opened after installation, the connection shall be tight.

　　4. 输送凝结水或含湿量较大的气体时，水平管线应设置坡度，排水管道应在更低点连接。安装时管道底部不应出现纵向接缝，底部接缝应密封。

　　4. When transporting condensate or gas with large moisture content, the horizontal pipeline shall be provided with gradient, and the drainage pipeline shall be connected at the lowest point. During installation, there shall be no longitudinal joint at the bottom of the pipe, and the bottom joint shall be sealed.

　　5. 输送易燃易爆气体的钢管应在连接法兰处安装跳线连接，并与静电地网连接。

　　5. The steel pipe conveying inflammable and explosive gas shall be connected with jumper wire at the connecting flange, and connected with electrostatic grounding grid.

　　6. 双吊杆支架就位后，横臂应伸直，吊杆不得更换，双吊杆受力应均匀。

　　6. After the double suspender bracket is in place, the cross arm shall be extended straight, the suspender shall not be replaced, and the stress of the double suspender shall be even.

　　7. 当水平风道高度大于2米时，安装人员应、配合。脚手架或可移动支架上的木板应固定，木板的宽度应符合标准，脚手架上的安装人员应背着背包，避免东西或电钻等掉落伤害。

　　7. When the height of horizontal air duct is more than 2m, the installation personnel shall be safe and cooperative. The board on the scaffold or movable support shall be fixed, and the width of the Board shall meet the standard. The installation personnel on the scaffold shall carry a backpack to avoid falling things or electric drills.
