Therefore, it is necessary to clean the ventilation pipe equipment regularly. How to clean it? Jinan ventilation pipe for you to introduce it.

　　(1)風道與風機連接時，進、出風口應安裝軟接頭。軟接頭的截面尺寸應與風機進出口截面尺寸一致。軟管連接可由帆布、人造革和其他材料制成。軟管長度不應小于200，并應適當擰緊。軟管可以緩沖風扇的振動。

　　(1) When the air duct is connected with the fan, soft joints shall be installed at the air inlet and outlet. The section size of soft joint shall be consistent with that of fan inlet and outlet. Hose connections can be made of canvas, leatherette, and other materials. The hose length shall not be less than 200 and shall be properly tightened. The hose dampens the vibration of the fan.

During installation, there shall be no longitudinal joint at the bottom of the air duct, and the bottom joint shall be hung for sealing.

　　(5)輸送易燃易爆氣體的鋼板風道，在風道連接法蘭處安裝跳線，并與靜電接地網連接。

　　(5) For the steel plate air duct conveying inflammable and explosive gas, install jumpers at the connecting flange of the air duct and connect with the electrostatic grounding grid.

　　(6)水平風道高度在4m以上時，安裝人員應系好安全帶。腳手架或活動支架上的跳板應固定，跳板寬度應符合安全規范，腳手架上的設備人員應隨身攜帶物品袋，避免物品或電鉆等掉落傷人。
