　　First of all, the installation of ventilation pipes, first of all, notice that in fact it is also in the ventilation pipe assembly, in a relatively short period of time in the pipeline, to a large extent, it can also be a ground assembly, followed by pipelines for a long period of time, to a large extent, in fact, it can also be directly assembled in the ground unit according to the status of the installation site.

　　風(fēng)管裝配時，風(fēng)管的和水平應(yīng)盡可能調(diào)整，在很大程度上可以直接避免風(fēng)管的變形或上下波動和左右擺動。此外，應(yīng)該注意的是，每個部分的風(fēng)道不應(yīng)超過10m。裝配時應(yīng)將墊片壓平，法蘭螺栓擰緊均勻，使螺母帽面朝同一方向。

　　When the duct is assembled, the center and level of the duct should be adjusted as far as possible. To a large extent, the deformation or fluctuation of the duct can be avoided directly. In addition, it should be noted that each part of the duct should not exceed 10m. When assembling, gaskets should be flattened, flange bolts should be tightened evenly, so that the nut face faces in the same direction.

　　此外,通風(fēng)管道,管道之前到位,很大程度上其實也應(yīng)該注意對水的直接檢查所有支架與海拔度,然后,注意應(yīng)該是直接檢查的程度強烈的腿,管的地方也可以采用直接和傳播者,這兩個方法。

　　In addition, ventilation pipes, pipes in place before, to a large extent, should also pay attention to the direct inspection of water support and altitude, and then, pay attention to the degree of direct inspection should be strong legs, pipes can also use direct and disseminator, these two methods.

　　那么，對于通風(fēng)管道截面相對較小，且其位置相對較低，在很大程度上，其實可以直接采用人工就位的方法，只需要直接設(shè)置簡單的腳手架也可以。

　　Then, for the ventilation duct section is relatively small, and its location is relatively low, to a large extent, in fact, the method of manual positioning can be used directly, as long as a simple scaffold can be directly set up.

　　后告訴大家，通風(fēng)管道上的風(fēng)管截面在其管道截面上較大較長，其實就是在其很大程度上可以直接采用滑輪、倒角鏈或大繩等方法。為了方便在通風(fēng)管道上安裝風(fēng)管，應(yīng)注意風(fēng)管應(yīng)直接懸掛在腳手架上。

　　Finally, let us know that the cross section of the air duct in the ventilation duct is larger and longer than that in the duct section. In fact, to a large extent, pulleys, chains or ropes can be directly used. In order to facilitate the installation of air ducts on ventilation pipes, it should be noted that air ducts should be directly suspended on scaffolding.
