        通風管道安裝加工系統的支撐原則

        來源:http://www.boursomarket.com 日期:2021-05-25 發布人:jntfgd

        通風管道安裝加工系統的支撐原則管道不宜與閥件直接支撐在設備上,應單獨設置支架或吊架,管道的焊縫位置應在施工方便或受力較小的地方,焊縫不得位于支架處且距離不小于200mm。
        The support principle of the ventilation pipe installation and processing system is that the pipe should not be directly supported on the equipment with the valve, and the support or hanger should be set separately. The welding position of the pipe should be in the place where the construction is convenient or the stress is small, and the welding seam should not be located at the support and the distance should not be less than 200 mm.
        不同含塵氣體性質不同,則凈化的分段處理應不同。通風管道加工系統布局中要保證整體系統的漏損小,確保吸塵口的有足夠的風量。通風管道加工系統布局要減小阻力。圓形風管強度大耗材少,但加工工藝復雜些,占用空間大;不銹鋼風管易布置,容易加工,因而使用較為普遍。山東通風管道還有系機械化生產由鋼帶螺旋繞制而成,有圓形、矩形,為節省空間,大量的不銹鋼風管做成扁圓形。
        If the properties of different dust gases are different, the purification process should be different. In the layout of the ventilation pipe processing system, the leakage of the whole system should be small, and the air volume at the suction port should be enough. The layout of ventilation pipe processing system should reduce the resistance. The circular duct has high strength and less consumables, but the processing technology is more complex and takes up more space; Stainless steel duct is easy to arrange and process, so it is widely used. Shandong ventilation pipe is also mechanized production, which is made of spiral steel strip, with round and rectangular shape. In order to save space, a large number of stainless steel air pipes are made into oblong shape.

        風管商場上按材質一般分為三類:鍍鋅不銹鋼風管、不銹鋼不銹鋼風管以及復合不銹鋼風管。其中,不銹鋼風管質量較好,適用性強,但價位高。現在商場上較廣的不銹鋼風管是鍍鋅板的。鍍鋅板不銹鋼風管,基本是不銹鋼不銹鋼風管的特性,可是價位相對只要不銹鋼風管的三分之二乃至更低。
        According to the material, the air duct is generally divided into three categories: galvanized stainless steel air duct, stainless steel air duct and composite stainless steel air duct. Among them, the quality of stainless steel duct is better, the applicability is strong, but the price is high. The stainless steel air duct widely used in shopping malls is galvanized. Galvanized stainless steel duct is basically the characteristics of stainless steel duct, but the price is only two-thirds or even lower than that of stainless steel duct.
        復合不銹鋼風管一般運用在外界環境較為一般,對風管要求不太高的場所。因為鐵皮容易在各種環境下發生化學反應,造成腐蝕、生銹。山東通風管道而鋅在干燥的空氣中幾乎不發生變化。在潮濕的空氣中,鋅表面會生成細密的堿式碳酸鋅膜。不銹鋼風管主要是在風管鐵皮上鍍上一層鋅,對鐵皮起到保護的效果。鋅鍍層經鈍化處理、染色或涂覆護光劑后,能顯著進步其防護性和裝飾性。
        The composite stainless steel air duct is generally used in the places where the external environment is general and the requirements for the air duct are not too high. Because the iron sheet is easy to have chemical reaction in various environments, causing corrosion and rust. However, zinc in the dry air is almost unchanged. In humid air, a fine basic zinc carbonate film is formed on the surface of zinc. The stainless steel air duct is mainly plated with a layer of zinc on the iron sheet of the air duct to protect the iron sheet. The protective and decorative properties of zinc coating can be improved significantly after passivation, dyeing or coating with light protecting agent.
        濟南通風管道由保溫層雙面復合保護層制作而成,保溫層又要緊分為泡沫和玻璃棉兩大類。山東通風管道多見的風管板為鋁箔復合酚醛泡沫板、鋁箔復合聚氨酯泡沫板、鋁箔復合擠塑聚苯乙烯泡沫板、保溫玻璃棉風管板等。這類風管在運用性能上相對抱負,導熱系數小、輕質、易施工、潔凈等,當前曾經運用在許多大眾民用設備中,包含高層設備內
        The ventilation pipe of Ji'nan is made of double layer compound protective layer of insulation layer, and the insulation layer is divided into two categories: foam and glass wool. The duct panels commonly seen in Shandong ventilation ducts are aluminum foil composite phenolic foam board, aluminum foil composite polyurethane foam board, aluminum foil composite extruded polystyrene foam board, thermal insulation glass cotton air duct plate, etc. This kind of duct is relatively ideal in application performance, with small thermal conductivity, light weight, easy construction, clean and so on. At present, it has been used in many public and civil equipment, including high-rise equipment
