濟南通風管道加工材料是不容易生銹的不銹鋼制作。事實上，這些不銹鋼同時具有防銹性和耐酸性。不銹鋼的防銹性和耐腐蝕性是由于在其表面形成富鉻氧化膜(鈍化膜)。這種防銹性和耐腐蝕性是相對具備一定優勢的。

Jinan ventilation pipe processing material is not easy to rust stainless steel production. In fact, these stainless steels have both rust and acid resistance. The rust and corrosion resistance of stainless steel is due to the formation of chromium rich oxide film (passive film) on its surface. This kind of antirust and corrosion resistance is relatively has certain advantages.

當管道較短時，可在地面上一次性組裝;當管道較長時，可根據安裝地點在地面上分段組裝。組裝時，應盡可能調整管道的水平度，避免管道扭曲或波動，并左右搖擺。組裝每段管道時，墊片應平整，法蘭螺栓應均勻擰緊，螺母和蓋應朝向同一方向。

When the pipeline is short, it can be assembled on the ground at one time; when the pipeline is long, it can be assembled on the ground in sections according to the installation location. During assembly, the levelness of the pipe should be adjusted as far as possible to avoid distortion or fluctuation of the pipe and swing left and right. When assembling each section of pipe, the gasket shall be flat, the flange bolts shall be tightened evenly, and the nuts and covers shall face in the same direction.

為了便于風道就位，一般采用將風道吊在腳手架上，然后將其吊在風道支架上。腳手架應沿其風道，長度方向設置，其高度和位置應適合施工作業。吊裝順序應為先主后分支和立管。吊裝時，吊點應應牢固，兩個吊點應應受力均勻。垂直風道可由人力和大繩輔助就位。調整風道，確保垂直度要求。

In order to facilitate the air duct in place, the air duct is usually hoisted on the scaffold, and then hoisted on the air duct support. The scaffold shall be set along its air duct and length, and its height and position shall be suitable for construction. The hoisting sequence shall be the main pipe before the branch pipe and the riser. When lifting, the lifting points shall be firm, and the stress of the two lifting points shall be uniform. The vertical air duct can be positioned by manpower and rope. Adjust the air duct to ensure the verticality.

在安裝廚房通風管道的時候，要讓風管和風機緊密的連接在一起，關于除塵設備和加熱設備，我們應根據實際情況進行預制和安裝，這樣才能起到相應的作用，管道的底部要密封結實，不要出現漏水和漏風的情況，畢竟安裝廚房管道不是那么容易的事情，還是要仔細一些。

When installing the kitchen ventilation pipe, we should make the air pipe and the fan closely connected together. As for the dust removal equipment and heating equipment, we should prefabricate and install them according to the actual situation, so as to play a corresponding role. The bottom of the pipe should be firmly sealed, and there should be no water leakage and air leakage. After all, it is not so easy to install the kitchen pipe, but it should be carefully done Be careful.

在排煙口安裝風扇式四葉或六葉排煙風機，增加排煙量或更換大風量風機。

Install fan type four leaf or six leaf smoke exhaust fan at the smoke exhaust outlet to increase the smoke exhaust volume or replace the high wind fan.

沒有其他好方法。檢查哪個問題比較嚴重。檢查煙罩和煙道是否漏氣，這樣可以緩解一些問題。如果這還不夠，所以它可能不得不改變。如果降低成本，可以保留排煙罩。

There is no other good way. Check which problem is more serious. Check the hood and flue for air leakage, which can alleviate some problems. If that's not enough, it may have to change. If the cost is reduced, the smoke hood can be retained.

管道通常由鍍鋅板和不銹鋼制成。小管道的薄板不能像天然氣管道和熱密封管道那樣完全密封和對接!

Pipes are usually made of galvanized sheet and stainless steel. The thin plate of small pipeline cannot be completely sealed and butted like natural gas pipeline and heat sealed pipeline!

由于新安裝的濟南排煙罩不能進行水壓試驗和檢漏，后期涂密封膠時不能完全粘接!

Because the newly installed Jinan exhaust hood can't be subjected to hydrostatic test and leak detection, it can't be completely bonded when the sealant is applied later!
