專注通風(fēng)管道加工·排煙罩

1. power wash: use pneumatic or electric brush to brush dirt, then dirt is sucked into the vacuum collector with the same method and direction as gas washing. This method requires as much care as possible to avoid damaging the surface of the insulation.

2.氣體沖洗：這種方法借助連接到風(fēng)管的配有噴嘴的軟管以輸送壓縮空氣。設(shè)計噴嘴使得壓縮空氣能夠把塵土和污物驅(qū)趕出去。而被壓縮空氣去干的污物和塵土則順著風(fēng)管被輸送到真空集容器中。

2. gas flushing: this method delivers compressed air by means of a hose with a nozzle attached to the air pipe. The design nozzle allows compressed air to expel dirt and dirt. Dirt and dust which are compressed air to dry are carried along the duct into the vacuum vessel.

3.真空吸污：用類似有手握式的真空吸污管來操作。用刷子直接接觸管道內(nèi)壁以污物。

3. vacuum suction: operated with a vacuum suction pipe like hand type. Direct contact with the wall of a pipe with a brush to remove dirt.

這種方法需要風(fēng)管有較大的檢修孔使操作的人員能夠盡可能夠得到。但這種方法可能漏掉一部分塵土和污物，因為風(fēng)管不能形成完全的負(fù)壓條件。而以下幾種方法可以形成負(fù)壓條件。

This method requires larger manholes to allow the operator to get as much of it as possible. But this method is most likely to miss out on a fraction of dust and dirt because the duct does not form complete negative pressure conditions. The following methods can form negative pressure conditions.
