濟(jì)南通風(fēng)管道加工材料是不容易生銹的不銹鋼制作。事實(shí)上，這些不銹鋼同時(shí)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(duì)具備一定優(yōu)勢(shì)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(dāng)管道較短時(shí)，可在地面上一次性組裝;當(dāng)管道較長(zhǎng)時(shí)，可根據(jù)安裝地點(diǎn)在地面上分段組裝。組裝時(shí)，應(yīng)盡可能調(diào)整管道的水平度，避免管道扭曲或波動(dòng)，并左右搖擺。組裝每段管道時(shí)，墊片應(yīng)平整，法蘭螺栓應(yīng)均勻擰緊，螺母和蓋應(yīng)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(fēng)道就位，一般采用將風(fēng)道吊在腳手架上，然后將其吊在風(fēng)道支架上。腳手架應(yīng)沿其風(fēng)道，長(zhǎng)度方向設(shè)置，其高度和位置應(yīng)適合施工作業(yè)。吊裝順序應(yīng)為先主后分支和立管。吊裝時(shí)，吊點(diǎn)應(yīng)應(yīng)牢固，兩個(gè)吊點(diǎn)應(yīng)應(yīng)受力均勻。垂直風(fēng)道可由人力和大繩輔助就位。調(diào)整風(fēng)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(fēng)管道的時(shí)候，要讓風(fēng)管和風(fēng)機(jī)緊密的連接在一起，關(guān)于除塵設(shè)備和加熱設(shè)備，我們應(yīng)根據(jù)實(shí)際情況進(jìn)行預(yù)制和安裝，這樣才能起到相應(yīng)的作用，管道的底部要密封結(jié)實(shí)，不要出現(xiàn)漏水和漏風(fēng)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(xì)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(fēng)扇式四葉或六葉排煙風(fēng)機(jī)，增加排煙量或更換大風(fēng)量風(fēng)機(jī)。

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(gè)問題比較嚴(yán)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(duì)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(jì)南排煙罩不能進(jìn)行水壓試驗(yàn)和檢漏，后期涂密封膠時(shí)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!
