With the development, Jinan ventilation duct is widely used in all walks of life, but with the continuous growth of service time, Jinan ventilation duct will accumulate a lot of impurities. These impurities will be stored in the pipeline for a long time, which will accelerate the condensation of oil during operation. If the temperature conversion is too high, the air pressure valve, hydraulic and other components will be damaged, seriously affecting the normal operation. Therefore, it is necessary to clean the ventilation duct equipment regularly. But how to clean it up?

(1)風管與風機連接時，進風口和出風口應安裝軟接頭。軟接頭的橫截面尺寸應與風機入口和出口的橫截面尺寸相同。軟管連接器可以由帆布、人造革和其他材料制成。軟管的長度不應小于200，且緊密度應適當。軟管可以緩沖風扇的振動。

(1) When the air duct is connected with the fan, the air inlet and outlet should be installed with soft joints. The cross-sectional dimension of the flexible joint shall be the same as that of the fan inlet and outlet. Hose connectors can be made of canvas, synthetic leather and other materials. The length of the hose should not be less than 200 and the tightness should be appropriate. The hose can cushion the vibration of the fan.

(2)風管與除塵設備和加熱設備連接時，設備安裝完畢后，根據理論測繪圖暫停預制安裝。

(2) When the air duct is connected with the dust removal equipment and heating equipment, the prefabrication and installation shall be suspended according to the theoretical mapping map after the equipment is installed.

(3)在濟南，安裝通風管時，預制風管時應打開進出口。如果風管需要在安裝結束時打開，其接口應緊密。

(3) In Jinan, when installing the ventilation pipe, the inlet and outlet should be opened when the air duct is prefabricated. If the duct needs to be opened at the end of installation, its interface should be tight.

(4)輸送冷凝水或含水量較大的氣體時，水平管道應有坡度，并在低點與排水管連接。安裝時，風管底部不應出現縱向接縫，底部接縫處應暫停密封處理。

(4) The condensate pipe should be connected with the drain pipe at the low point of the water content. During installation, the longitudinal joint should not appear at the bottom of the air duct, and the sealing treatment should be suspended at the bottom joint.

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

(5) For steel plate air duct conveying inflammable and explosive gas, jumper shall be installed at the connecting flange of air duct and connected with electrostatic grounding grid.

(6)當水平風道高度超過4m時，安裝人員應佩戴安 全帶。腳手架或移動支架上的跳板應固定好，跳板的寬度應符合安 全規范。腳手架上的設備人員應攜帶袋子，以免掉落物體或電鉆傷人。

(6) When the height of horizontal air duct exceeds 4m, the installation personnel shall wear safety belt. The springboard on the scaffold or mobile support shall be fixed, and the width of the gangway shall comply with the safety regulations. Equipment personnel on the scaffold should carry bags to avoid falling objects or electric drill from hurting people.

(7)雙吊桿支架在風道，就位后，橫臂應平直，吊桿不應改變，雙吊桿應受力均勻。

(7) After the double suspender bracket is in place in the air duct, the cross arm should be straight, the suspender should not be changed, and the double suspender should be stressed evenly.

以上就是濟南通風管道向您介紹的關于清理濟南通風管道雜質的方法，濟南通風管道應該每三個月清洗一次，這樣既能保證平時的正常運行，又能延長通風管道的使用壽命。

The above is the Jinan ventilation duct introduced to you about the cleaning method of Jinan ventilation duct impurities, Jinan ventilation duct should be cleaned every three months, so as to ensure normal operation at ordinary times, and can extend the service life of the ventilation duct.
