通风管道风管加工存在哪些缺陷?

来源: 日期:2019-06-20 发布人:admin

  它们的性能差距并不大,但是在这个过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:板材采用机械统一加工,钢杆厚度fl.3mm左右,不能根据钢管的尺寸进行调整,没有其他加固措施,强度平方!在应用大管道时,对风道的作用略显不足。此外,由于双层彩钢板内外板表面的分离,内板承受较大的压力,外板的变形和表面不平整会影响管道的整体性能。但镀锌钢管的钢箱体干燥度可根据规范要求灵活调整。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 deion 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、法兰形式:双面彩板熨风风管采用PVC复合法兰,这种法兰容易老化,有接缝,影响漏风大厅与水从连接进入保温层。法兰被提升到管道中,增加沿途的阻力。另外,这种法兰不能与风机和机组连接,双面彩钢管与风口连接不方便处理。而镀锌钢管法的角钢为71-1框架,内壁为平管,使其阻力小于双面彩格列复合风管,而风机、机组与风口的连接也有成熟的工艺。
  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、保温形式:双面彩钢杆熨烫风管采用夹芯保温。保温层的材料、厚度、填充程度以及胶水的击穿和阻燃性都不能进行检测。水果保温层不渗透水蒸气,会导致保温材料腐烂,腐烂的保温材料无法更换。
  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.
  另双k[彩钢板复合管法兰接头上_无保温,保温效果好。双层彩钢风管的外层为轻属铝板,在炎热、潮湿的气候条件下容易形成冷凝,尤其是夹层保温下局部损伤重的尤为严格。但镀锌钢风管已经形成了成熟的保温方法,工艺、质量都得到了保证,应用木结构也克服了常见的“冷桥现象”,是目前在通风空调保温材料的选择中,橡胶保温板是合适的保温材料。

  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.
  运输管道在当今的承载对象中占有重要的地位和作用。因此,管道的防腐保温处理越来越受到人们的重视。
  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.
  当风管输送一般气体时,黑色钢质风管应除锈,刷防锈漆处理,粉尘气体可喷涂防磨保护层,当周围空气湿度较大时,风管外墙需做防腐、防锈处理。输送高温、高湿气体镀锌钢风管内壁应喷涂磷化底漆或其他耐腐蚀涂料。当风管输送高温气体或低温空气时,风管外壁应进行保温(冷保温)处理。
  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).
  高温燃气管道保温的目的是防止管道内空气的热损失(冬季出现在集中空调系统中)。另外是防止在输送余热蒸汽或高温气体时,防止热量散发到室内,使室内温度升高,并可防止人们接触风管而被烫伤。夏季,当气体温度低于周围空气露点温度时,管道外壁会形成露点。中央空调系统的风管会增加制冷量的损失,凝结的水滴会污染天花板和墙面地板,所以也要进行保温。
  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.
