济南通风管道加工材料是不容易生锈的不锈钢制作。事实上，这些不锈钢同时具有防锈性和耐酸性。不锈钢的防锈性和耐腐蚀性是由于在其表面形成富铬氧化膜(钝化膜)。这种防锈性和耐腐蚀性是相对具备一定优势的。
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.
当管道较短时，可在地面上一次性组装;当管道较长时，可根据安装地点在地面上分段组装。组装时，应尽可能调整管道的水平度，避免管道扭曲或波动，并左右摇摆。组装每段管道时，垫片应平整，法兰螺栓应均匀拧紧，螺母和盖应朝向同一方向。
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.
为了便于风道就位，一般采用将风道吊在脚手架上，然后将其吊在风道支架上。脚手架应沿其风道，长度方向设置，其高度和位置应适合施工作业。吊装顺序应为先主后分支和立管。吊装时，吊点应应牢固，两个吊点应应受力均匀。垂直风道可由人力和大绳辅助就位。调整风道，确保垂直度要求。
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.
在安装厨房通风管道的时候，要让风管和风机紧密的连接在一起，关于除尘设备和加热设备，我们应根据实际情况进行预制和安装，这样才能起到相应的作用，管道的底部要密封结实，不要出现漏水和漏风的情况，毕竟安装厨房管道不是那么容易的事情，还是要仔细一些。
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.
在排烟口安装风扇式四叶或六叶排烟风机，增加排烟量或更换大风量风机。
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.
没有其他好方法。检查哪个问题比较严重。检查烟罩和烟道是否漏气，这样可以缓解一些问题。如果这还不够，所以它可能不得不改变。如果降低成本，可以保留排烟罩。
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.
管道通常由镀锌板和不锈钢制成。小管道的薄板不能像天然气管道和热密封管道那样完全密封和对接!
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!
由于新安装的济南排烟罩不能进行水压试验和检漏，后期涂密封胶时不能完全粘接!
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!
