一、通风管道设备程序:

快盈11v1、 Ventilation duct equipment program:

快盈11v(1)风管组装:当风管较短时,可一次在地上组装而成,当风管较长时,可视设备场所的状况,在地上分段组装。组装时应尽量调整风道的中心度和水平度,避免风管歪曲或上下起波,左右摆龙,每段风道不宜逾越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。

(1) Air duct assembly: When the air duct is short, it can be assembled on the ground in one go. When the air duct is long, it can be assembled in segments on the ground depending on the condition of the equipment location. During assembly, the centrality and levelness of the air duct should be adjusted as much as possible to avoid distortion or wave formation, left and right swinging, and each section of the air duct should not exceed 10 meters. During assembly, the gasket should be leveled, the flange bolts should be tightened evenly, and the nuts and caps should be facing in the same direction.

(2)风管就位:风管就位前应查看悉数支架的水乎度和标高、查看支架的健壮程度,风管就位可选用直接和吊具两种办法。对风管断面较小,又方位较低的可选用人工就位办法,只需搭设简易脚手架即可。当风管断面较大且管段较长时,可选用滑轮、倒链、大绳等办法吊装。世纪星介绍为了便于风道就位,一般多选用将风道吊在脚手架上,然后再将其抬放在风道支架上的办法。脚手架应沿其风道长度方向搭设,高度和方位应适宜施工操作,吊装次序应先干管后支、立管,吊起时,吊点应健壮,两吊点应均匀受力。笔直风管可选用人工和大绳辅佐就位。调整风管确保笔直度要求。

(2) Air duct positioning: Before positioning the air duct, the water level and elevation of all supports should be checked, and the robustness of the supports should be checked. There are two methods for positioning the air duct: direct and lifting. For ducts with smaller cross-sections and lower orientations, manual positioning can be used, which only requires the installation of simple scaffolding. When the cross-section of the air duct is large and the pipe section is long, methods such as pulleys, chain blocks, and large ropes can be used for hoisting. Century Star introduces that in order to facilitate the positioning of the air duct, it is generally used to hang the air duct on a scaffold and then lift it onto the air duct bracket. Scaffolding should be erected along the length direction of its air duct, and the height and orientation should be suitable for construction operations. The lifting sequence should start with dry pipes and then support and stand pipes. When lifting, the lifting points should be robust, and the two lifting points should be evenly stressed. The straight air duct can be manually and with the assistance of a large rope in place. Adjust the air duct to ensure the required straightness.

快盈11v(3)风道调直:就位在支架上的风道,应拨正方位,调整风道横平竖直,然后再按图集要求固定。

快盈11v(3) Air duct straightening: The air duct placed on the bracket should be aligned, adjusted horizontally and vertically, and then fixed according to the requirements of the atlas.

快盈11v二、通风管道在设备时的留神事项:

快盈11v2、 Precautions for ventilation ducts during equipment installation:

快盈11v(1)对运送易燃、易爆气体的钢板风道,在风道联接法兰处应设备跨接线,并与静电接地网联接。

快盈11v(1) For steel plate air ducts transporting flammable and explosive gases, a jumper wire should be installed at the flange connection of the duct and connected to the electrostatic grounding network.

快盈11v(2)当风道与除尘设备、加热设备等联接前,应待设备设备结束后,按实践测绘的图纸进行预制和设备。

(2) Before connecting the air duct with dust removal equipment, heating equipment, etc., prefabrication and equipment should be carried out according to the practical mapping drawings after the equipment is completed.

快盈11v(3)风道设备时,进、出风日宜在风道预制时开出洞口,如需在设备结束的风道上现开风口,其接口处应紧密。

快盈11v(3) When using air duct equipment, it is advisable to open openings during the prefabrication of the air duct for both inlet and outlet days. If it is necessary to open openings on the air duct at the end of the equipment, the interface should be tight.

(4)当运送含凝聚水或含湿量较大的气体时,其水平管道宜设有斜度,并在低点处接排水管。设备时风道底部不宜呈现纵向接缝,对底部有接缝处应进行密封处理。

快盈11v(4) When transporting gas containing condensed water or high moisture content, the horizontal pipeline should have a slope and a drainage pipe should be connected at the low point. The bottom of the air duct should not have longitudinal joints during equipment operation, and sealing treatment should be carried out on the joints at the bottom.

(5)当风管与风机联接时,应在进出风口处加软接头,其软接头的断面规范应与风机进出风口共同。软管接头一般可选用帆布、人造革等资料,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荡。

(5) When connecting the air duct to the fan, a soft joint should be added at the inlet and outlet, and the cross-sectional specification of the soft joint should be consistent with the inlet and outlet of the fan. The hose joint can generally use materials such as canvas or synthetic leather. The length of the hose should not be less than 200, and the tightness should be appropriate. The flexible hose can buffer the oscillation of the fan.
