        山東通風管道在加工過程中有哪些缺陷?

         它們的性能差距并不大,但是在這個過程中仍然存在一些缺陷:
          Their performance gap is not large, but there are still some shortcomings in this process:
          1、板材性能:板材采用機械統一加工,鋼桿厚度fl.3mm左右,不能根據鋼管的尺寸進行調整,沒有其他加固措施,強度平方!在應用大管道時,對風道的作用略顯不足。此外,由于雙層彩鋼板內外板表面的分離,內板承受較大的壓力,外板的變形和表面不平整會影響管道的整體性能。但鍍鋅鋼管的鋼箱體干燥度可根據規范要求靈活調整。管三通
          1. Performance of sheet metal: the thickness of steel rod is about fl.3mm, which can not be adjusted according to the size of steel pipe. There are no other reinforcement measures, and the strength is square. When using large pipeline, the effect on air duct is slightly insufficient. In addition, due to the separation of the inner and outer surface of double-layer color steel plate, the inner plate is subjected to greater pressure, and the deformation and surface irregularity of the outer plate will affect the overall performance of the pipeline. But the dryness of galvanized steel tube can be adjusted flexibly according to the specifications. Pipe tee
          2、法蘭形式:雙面彩板熨風風管采用PVC復合法蘭,這種法蘭容易老化,有接縫,影響漏風大廳與水從連接進入保溫層。法蘭被提升到管道中,增加沿途的阻力。另外,這種法蘭不能與風機和機組連接,雙面彩鋼管與風口連接不方便處理。而鍍鋅鋼管法的角鋼為71-1框架,內壁為平管,使其阻力小于雙面彩格列復合風管,而風機、機組與風口的連接也有成熟的工藝。
          2. Flange form: PVC composite flange is used for double-sided color plate ironing air duct. This kind of flange is easy to aging and has joints, which affects the air leakage hall and water from the connection into the insulation layer. Flanges are lifted into pipes to increase resistance along the way. In addition, the flange can not be connected with the fan and the unit, and the connection between the double-sided color steel pipe and the tuyere is inconvenient to handle. The angle steel of galvanized steel pipe method is 71-1 frame, the inner wall is flat tube, so that its resistance is less than double-sided coloured grid composite air duct, and the connection between fan, unit and tuyere has mature technology.
          3、保溫形式:雙面彩鋼桿熨燙風管采用夾芯保溫。保溫層的材料、厚度、填充程度以及膠水的擊穿和阻燃性都不能進行檢測。水果保溫層不滲透水蒸氣,會導致保溫材料腐爛,腐爛的保溫材料無法更換。
          3. Heat preservation form: double-sided stainless steel rod ironing air duct adopts sandwich heat preservation. The insulation material, thickness, filling degree, breakdown and flame retardancy of glue can not be tested. Fruit insulation layer does not penetrate water vapor, which will lead to the decay of insulation materials, which can not be replaced.
          另雙k[彩鋼板復合管法蘭接頭上_無保溫,保溫效果好。雙層彩鋼風管的外層為輕屬鋁板,在炎熱、潮濕的氣候條件下容易形成冷凝,尤其是夾層保溫下局部損傷重的尤為嚴格。但鍍鋅鋼風管已經形成了成熟的保溫方法,工藝、質量都得到了保證,應用木結構也克服了常見的“冷橋現象”,是目前在通風空調保溫材料的選擇中,橡膠保溫板是合適的保溫材料。

          Another double K [color steel plate composite pipe flange joint no heat preservation, good heat preservation effect. The outer layer of the double-layer color steel air duct is light aluminum plate. It is easy to form condensation in hot and humid climate, especially in the case of sandwich insulation, the local damage is particularly severe. But galvanized steel air duct has formed a mature insulation method, technology and quality have been guaranteed, the use of wood structure also overcome the common "cold bridge phenomenon", is currently in the selection of ventilation and air conditioning insulation materials, rubber insulation board is the most suitable insulation material.
          運輸管道在當今的承載對象中占有重要的地位和作用。因此,管道的防腐保溫處理越來越受到人們的重視。
          Transportation pipelines play an important role in the current load-bearing objects. Therefore, people pay more and more attention to pipeline anti-corrosion and heat preservation treatment.
          當風管輸送一般氣體時,黑色鋼質風管應除銹,刷防銹漆處理,粉塵氣體可噴涂防磨保護層,當周圍空氣濕度較大時,風管外墻需做防腐、防銹處理。輸送高溫、高濕氣體鍍鋅鋼風管內壁應噴涂磷化底漆或其他耐腐蝕涂料。當風管輸送高溫氣體或低溫空氣時,風管外壁應進行保溫(冷保溫)處理。
          When the air duct conveys general gas, the black steel air duct should be rusted, brushed with anti-rust paint. Dust gas can be sprayed with anti-wear protective layer. When the ambient air humidity is high, the external wall of the air duct should be treated with anti-corrosion and anti-rust. Phosphating primer or other anticorrosive coating should be sprayed on the inner wall of galvanized steel duct conveying high temperature and humidity gas. When the air duct conveys high temperature gas or low temperature air, the outer wall of the air duct should be treated with heat preservation (cold heat preservation).
          高溫燃氣管道保溫的目的是防止管道內空氣的熱損失(冬季出現在集中空調系統中)。另外是防止在輸送余熱蒸汽或高溫氣體時,防止熱量散發到室內,使室內溫度升高,并可防止人們接觸風管而被燙傷。夏季,當氣體溫度低于周圍空氣露點溫度時,管道外壁會形成露點。空調系統的風管會增加制冷量的損失,凝結的水滴會污染天花板和墻面地板,所以也要進行保溫。
          The purpose of high temperature gas pipeline insulation is to prevent the heat loss of air in the pipeline (which occurs in central air conditioning system in winter). In addition, it prevents heat from radiating into the room when conveying waste heat steam or high temperature gas, which can raise the indoor temperature and prevent people from being scalded by contacting air ducts. In summer, when the gas temperature is lower than the dew point temperature of the surrounding air, dew point will be formed on the outer wall of the pipeline. The air duct of central air-conditioning system will increase the loss of refrigeration capacity. Condensed water droplets will pollute the ceiling and wall floors, so thermal insulation should also be carried out.
