山東通風管道加工前應采用清洗液去除板材表面油污及積塵，清洗液應采用對板材表面無損害、干燥后不產生粉塵，且對人體無危害的中性清潔劑。通風管道制作完畢應使用清洗液清洗，清洗后經白綢布擦拭檢查達到要求后，酚醛板，應及時封口。

　　Cleaning liquid should be used to remove oil pollution and dust accumulation on the surface of Shandong ventilation pipe before cleaning. The cleaning liquid shall be neutral detergent which has no damage to the surface of the sheet, does not produce dust after drying and has no harm to the human body. Ventilation pipe production should be used after cleaning fluid cleaning, cleaning after the white cloth wipe check to meet the requirements, the phenolic plate, should be promptly sealed.

　　彩色涂層鋼板風管的內壁應光滑;板材加工時不得損壞涂層，被損壞的部位應涂環氧樹脂。風管的咬口縫、鉚接縫以及法蘭翻邊四角縫隙處，應按設計及潔凈等級要求，采用涂密封膠或其他密封措施堵嚴。

　　The inner wall of the color coated steel pipe shall be smooth, and the sheet shall not be damaged during processing, and the damaged parts shall be coated with epoxy resin. The four corners of the wind pipe, such as the bite joint, the riveted joint and the flange flanging, shall be sealed by the coating sealant or other sealing measures according to the design and cleanliness grade requirements.

　　密封材料宜采用異丁基橡膠、氯丁橡膠、變性硅膠等為基材的材料。風管板材連接縫的密封面應設在風管壁的正壓側。

　　Sealing material should adopt isobutyl rubber, chloroprene rubber, modified silica gel as the base material. The sealing surface of the joint of the wind pipe plate shall be located on the positive pressure side of the air duct wall.

　　排煙風口什么情況下在管道的上面?

　　What is the exhaust vent on the top of the pipe?

　　1、排煙口規格與設計規格不符，排煙量自然會減少。

　　1, smoke exhaust specifications and design specifications inconsistent with the amount of smoke will naturally decrease.

　　2、有的風機安裝與管道安裝錯位，影響到煙氣流通。

　　2, some fan installation and pipe installation dislocation, affecting the flue gas circulation.

　　3、排煙口都設在室外，為了遮雨和防止鳥類進入，一般都在排煙口上設有防鳥欄和遮雨百頁，如設遮雨百頁，阻力就大，還有的設在房間內，排煙口沒有直接朝向窗口，而是對準墻面，就會影響到煙氣的排出。

　　3, the exhaust port are arranged on the outside, in order to prevent rain and birds enter, generally in the exhaust port is provided with an anti bird bar and rain 100 pages, such as a rain per page, resistance is large, there is no room, smoke directly toward the window, but on the wall, will affect the flue gas discharge.

　　4、檢查時風速儀所放的位置、距離也可能對測量風速有一定的影響，造成測定的數據不準而影響到排煙量的計算。

　　4, when checking, the position and distance of the anemometer may have some influence on the measurement of wind speed, which results in the inaccuracy of the measured data, and affects the calculation of the amount of smoke exhaust.

　　5、管道接頭漏煙氣，個別采用無機或阻燃玻璃鋼風管，在排煙機啟動之后甚破裂。

　　5 、 pipe joint leakage of smoke, individual use inorganic or flame retardant glass fiber reinforced plastic pipe, in the smoke exhaust machine after opening even rupture.

　　6、管道內阻力大，有的管道內有蛇皮袋、塑料薄膜等雜物未清理，有的磚砌排煙道內壁未粉刷，不光滑，造成阻力大。

　　6, large resistance pipe, the pipe has some snakeskin bag, plastic film and other debris to clean up, some brick flue wall is not painted, not smooth, resulting in high resistance.

　　7、排煙風管上為了防震，一般都設有軟接頭，軟接頭與硬管相接不嚴密，常有漏煙氣現象。

　　7, in order to shock the smoke exhaust pipe, generally have soft joints, soft joints and hard pipe connection is not tight, often leakage smoke phenomenon.

　　8、管道規格不符，管道截面積與設計截面積應當相匹配，有的因與其他管道安裝有沖突，而減少管道截面積，影響煙氣通過量。

　　8, the pipeline specifications do not match, the cross-sectional area of the pipeline should be matched with the design cross sectional area, and some because of the conflict with other pipe installation, and reduce the cross-sectional area of the pipe, affecting the amount of flue gas through.

　　9、管道過長，彎頭轉角多，阻力大，影響煙氣流速。

　　9 、 the pipe is too long, elbow corner is much, and the resistance is big, which affects the flow rate of flue gas.
