在通風管道加工安裝過程中，如果不注意正確的安裝方法，后果將更加嚴重。因此，在安裝過程中研究正確的操作過程非常重要。關于
山東通風管道加工安裝時的五個要點來詳細解說下。
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)對運輸易燃性、易燃易爆汽體的厚鋼板風道，在風道聯接法蘭盤處要安裝跨接線，并與靜電感應接地裝置網聯接。
(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)當風道與除塵器設備、加溫設備等聯接前，應待安裝設備結束后，按具體測繪工程的工程圖紙開展預制構件和安裝。
(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)風道安裝時，進、進風口日宜在風道預制構件時給出洞邊，如需在安裝結束的風道上現開出風口，其連接處應嚴實。
(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)當運輸含冷凝水或含濕量很大的汽體時，其水準管路宜下設傾斜度，并在底點處接排水管道。安裝時風道底端不適合出現豎向接縫處，對底端有接口處應開展密封性解決。
(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)當通風風管與離心風機聯接時，應在出入新風風口加軟接頭，其軟接頭的橫斷面規格應與離心風機進通風口一致。軟管接頭一般可選用白帆布、人造皮革等原材料，塑料軟管長短不適合低于200，松緊應適合，軟性塑料軟管可緩存離心風機的震動。
(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://m.pvcbox.cn consulting service
