　　With the continuous growth of service time, a large number of impurities will be accumulated in Jinan ventilation pipeline. These impurities will stay in the pipeline for a long time and accelerate the oil condensation during operation. Too high temperature conversion will damage the pneumatic valve and hydraulic components, and have a great impact on normal operation. 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.

　　(2)風管與除塵設備、加熱設備連接后，根據理論映射圖安裝好設備后，應暫停預制安裝。

　　(2) After the air duct is connected with the dedusting equipment and heating equipment, the prefabricated installation shall be suspended after the equipment is installed according to the theoretical mapping diagram.

　　(3)濟南風管安裝時，風管預制好后，應打開進、出口。如果需要在安裝結束時打開管道，則連接應緊密。

　　(3) When Jinan air duct is installed, the inlet and outlet shall be opened after the air duct is prefabricated. If it is necessary to open the pipe at the end of installation, the connection shall be tight.

　　(4)輸送高含水率凝結水或氣體時，水平管道應設置在斜坡處，并在低處與排水管連接。安裝時風管底部不應有縱向接縫，底部接縫處應懸掛密封處理。

　　(4) When transporting condensate or gas with high moisture content, the horizontal pipeline shall be set at the slope and connected with the drainage pipe at the low position. 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。

　　(6) When the height of horizontal air duct is more than 4m, the installation personnel shall fasten the safety belt. The springboard on the scaffold or movable support shall be fixed, and the width of the springboard shall meet the safety specifications. The equipment personnel on the scaffold shall carry the bag with them to avoid personal injury caused by falling objects or electric drills.
