通風(fēng)管道生產(chǎn)線設(shè)備沖口模具及剪板刀不能動(dòng)作，可能是電氣箱控制液壓電磁閥的連接線斷線，可能是電氣箱中間繼電器損壞，觸摸屏自動(dòng)加工頁(yè)面顯示為不沖口狀態(tài)或電磁閥卡滯。處理：檢查機(jī)器的電氣線路或設(shè)備是否損壞，及時(shí)更換修理。

The punching mold and cutting blade of the ventilation duct production line equipment cannot move, which may be due to a broken connection line of the hydraulic solenoid valve controlled by the electrical box, a damaged relay in the middle of the electrical box, a touch screen automatic processing page showing no punching status, or a stuck solenoid valve. Handling: Check if the electrical circuits or equipment of the machine are damaged, and replace and repair them in a timely manner.

通風(fēng)管道翹角及彎頭角度不準(zhǔn)：矩形框通風(fēng)管道兩相對(duì)性平面、兩邊面不平行;折角不豎直;直線不相同;咬口不緊。危害：會(huì)使風(fēng)管連接受力不均勻，安裝后的風(fēng)管不平直，法蘭盤墊片不嚴(yán)密，系統(tǒng)漏風(fēng)，造成空調(diào)負(fù)荷損失，并且縮短使用壽命。

The deflection angle and bend angle of the ventilation duct are not accurate: the two opposite planes of the rectangular frame ventilation duct and the two sides are not parallel; The folding angle is not vertical; Different straight lines; The bite is not tight. Harm: It can cause uneven stress on the air duct connection, uneven installation of the air duct, loose flange gasket, system air leakage, resulting in air conditioning load loss and shortened service life.

通風(fēng)管道原材料不合格：板才表面不整平，薄厚不勻稱，有顯著的壓印、裂縫、沙孔、結(jié)痂和生銹等狀況;通風(fēng)管道平面下沉，側(cè)邊向外突起，有顯著的形變。危害：運(yùn)行時(shí)風(fēng)管漏風(fēng)，中央空調(diào)負(fù)載提升，另外風(fēng)管使用壽命和特性被危害。

Unqualified raw materials for ventilation ducts: The surface of the board is uneven, the thickness is uneven, and there are significant imprints, cracks, sand holes, scabs, and rust; The ventilation duct sinks flat and protrudes outward on the side, showing significant deformation. Harm: Air duct leakage during operation, increased load on central air conditioning, and compromised service life and characteristics of the duct.
