  济南风管的加工主要由角码、夹具及与风管整体连接的连接件组成。虽然这种风管的成本相对较低,降低了角钢的消耗,但在实际应用中,其强度不如角钢,漏风也比较大。它必须用机床加工。手工制造是困难的。它通常只用于新风系统、空调系统等。排烟系统仍然是由角钢连接的风管。但人防工程绝对不允许使用公用板连接。
  The processing of Jinan air duct is mainly composed of corner codes, clamps and connectors connected with the air duct as a whole. Although the cost of this kind of air duct is relatively low and the consumption of angle steel is reduced, its strength is not as good as that of angle steel in practical application, and the air leakage is also relatively large. It has to be machined. It is difficult to make by hand. It is usually only used for fresh air system, air conditioning system, etc. The smoke exhaust system is still an air pipe connected by angle steel. But the civil air defense project is absolutely not allowed to use the common board connection.
  风管制作过程中的材料要求相当的讲究。当风管表面为铝箔时,为了保证表面不容易损坏,指定了铝箔材料和厚度,并指定了由铝箔和增强材料组成的风管表面的铝箔厚度。
  The material requirements in the air duct manufacturing process are quite exquisite. When the air duct surface is aluminum foil, in order to ensure that the surface is not easy to damage, the aluminum foil material and thickness are specified, and the aluminum foil thickness of the air duct surface composed of aluminum foil and reinforcement material is specified.
  薄钢板通风管道内外保温材料的粘结是保证复合材料的基本条件之一。板在一定范围内的缺陷不仅会影响风管的使用寿命,而且会降低风管的保温效果。因此,该缺陷必须不超过6,以实现材料在系统中的正常使用。
  One of the basic conditions to ensure the composite material is the bonding of the internal and external insulation materials of the thin steel ventilation pipe. The defects of the plate in a certain range will not only affect the service life of the air duct, but also reduce the insulation effect of the air duct. Therefore, the defect must not exceed 6 to achieve the normal use of materials in the system.

  非金属风管材料发展迅速,品种繁多。由于它们的特点和优点,得到了越来越广泛的应用。为了保证使用的保证,根据工程需要,建议这些材料制成的风管应具有不燃或不燃B1的燃烧性能要求,表层必须是不燃材料。根据多年的工程实践和我国产品的现状,对热压带的小剥离强度和铝箔厚度的测试值进行了规定。胶带宽度要求不小于50mm,以防止胶带不能满足壁封强度和管道使用寿命。热粘带的优点是它依赖于热熔粘合。只要不加热,胶粘剂的表面在室温下固化,并具有很强的粘接强度。
  Nonmetal air duct materials develop rapidly and have many kinds. Because of their characteristics and advantages, they have been more and more widely used. In order to ensure the use, according to the engineering needs, it is suggested that the air ducts made of these materials should have the combustion performance requirements of non combustible or non combustible B1, and the surface must be non combustible materials. According to the engineering practice for many years and the current situation of the products in China, the test values of the small peel strength and the thickness of the aluminum foil of the hot pressed strip are specified. The width of the tape shall not be less than 50mm to prevent the tape from failing to meet the wall sealing strength and the service life of the pipeline. The advantage of hot adhesive tape is that it depends on hot-melt bonding. As long as it is not heated, the surface of the adhesive solidifies at room temperature and has a strong bonding strength.
  风道加工是通风空调系统的重要组成部分。它们大多由管道加工设备制成,如管道生产线。然而,由于各种原因,风管处理设备处理的风管可能会出现问题。
  Air duct processing is an important part of ventilation and air conditioning system. Most of them are made by pipeline processing equipment, such as pipeline production line. However, for a variety of reasons, there may be problems with the ducts handled by the duct handling equipment.
