在通风管道加工安装过程中，如果不注意正确的安装方法，后果将更加严重。因此，在安装过程中研究正确的操作过程非常重要。关于
山东通风管道加工安装时的五个要点来详细解说下。
If the correct installation method is not paid attention to during the processing and installation of ventilation pipes, the consequences will be more serious. Therefore, it is very important to study the correct operation process during installation. The five key points of Shandong ventilation pipe processing and installation are explained in detail.
(1)对运输易燃性、易燃易爆汽体的厚钢板风道，在风道联接法兰盘处要安装跨接线，并与静电感应接地装置网联接。
(1) For thick steel plate air duct transporting flammable, combustible and explosive vapor, jumper wire shall be installed at the connecting flange of air duct and connected with electrostatic induction grounding device network.
(2)当风道与除尘器设备、加温设备等联接前，应待安装设备结束后，按具体测绘工程的工程图纸开展预制构件和安装。
(2) Before connecting the air duct with the dust remover equipment and the heating equipment, the prefabricated components and installation shall be carried out according to the engineering drawings of the specific mapping project after the installation of the equipment.
(3)风道安装时，进、进风口日宜在风道预制构件时给出洞边，如需在安装结束的风道上现开出风口，其连接处应严实。
(3) During the installation of the air duct, the air inlet and outlet should be provided with the hole edge at the time of prefabricated components of the air duct. If the air outlet needs to be opened on the air duct after installation, its connection should be tight.
(4)当运输含冷凝水或含湿量很大的汽体时，其水准管路宜下设倾斜度，并在底点处接排水管道。安装时风道底端不适合出现竖向接缝处，对底端有接口处应开展密封性解决。
(4) When transporting steam containing condensed water or large moisture content, its horizontal pipeline should be set with a gradient and connected with a drainage pipe at the bottom. During installation, the bottom of the air duct is not suitable for vertical joints, and the joints at the bottom shall be sealed.
(5)当通风风管与离心风机联接时，应在出入新风风口加软接头，其软接头的横断面规格应与离心风机进通风口一致。软管接头一般可选用白帆布、人造皮革等原材料，塑料软管长短不适合低于200，松紧应适合，软性塑料软管可缓存离心风机的震动。
(5) When the ventilation duct is connected with the centrifugal fan, a soft joint shall be added at the fresh air inlet and outlet, and the cross section specification of the soft joint shall be consistent with the inlet and outlet of the centrifugal fan. The hose connector can generally use white canvas, artificial leather and other raw materials. The length of plastic hose should not be less than 200, and the tightness should be appropriate. The soft plastic hose can buffer the vibration of the centrifugal fan.
The above is all about the five key points for the processing and installation of ventilation ducts. Thank you for your patience. Friends in need can come to our company http://www.jnqsg.com consulting service
