通风管道常见的特色有哪些?
1、防火功用好:其时普遍存在的问题是制品通风道燃烧功用和耐火极限未经国家有关部门检测,且部分通风道材料的燃烧功用、管壁厚度不符合要求。
 
  1. Good fireproof function: At that time, the common problem was that the burning function and fireproof limit of product ventilation duct had not been inspected by relevant state departments, and the burning function and wall thickness of some ventilation duct materials did not meet the requirements.
 
  2、造价低:济南通风管道与传统砖砌通风道比,能节约工程造价40%左右;
 
  2. Low cost: Jinan ventilation duct can save about 40% of the project cost compared with the traditional brick ventilation duct.
 
  3、轻质高强:与传统砖砌通风道比,菱镁通风道自重轻、强度高,能大幅度下降建筑物的承受荷载;
 
  3. Light weight and high strength: Compared with traditional brick ventilation duct, magnesite ventilation duct has light weight and high strength, which can greatly reduce the bearing load of buildings.
 
  4、规划活络:通风管道可根据预留洞的巨细,随时调整管道的标准标准;
 
  4. Planning flexible network: ventilation pipeline can adjust the standard standard of pipeline at any time according to the size of reserved holes;
 
  5、规划一起:通风管道的开口上装置了烟气止回阀和防火阻隔门,可以有用防止串味和串火;

  5. Planning together: flue gas check valves and fire barrier doors are installed at the opening of the ventilation pipeline, which can be used to prevent cross-smelling and crossfire.
 
  6、施工简略:增加了室内空间,密闭性好、不返烟、不返臭,能大幅度改进室内环境。
 
  6. Brief construction: Increased indoor space, good airtightness, no smoke return, no odor return, can greatly improve the indoor environment.
 
  螺旋风管在作业进程会发生必定的噪音,假定在住宅区和商业区会对人们的日子发生很大的影响。那么我们在施工进程中怎么削减噪音呢?
 
  The helical duct will produce certain noise in the process of operation, assuming that in residential and commercial areas will have a great impact on people's lives. So how do we reduce noise in the construction process?
 
  通风管道体系作业噪音一般来源于以下几个方面:
 
  The working noise of ventilation duct system generally comes from the following aspects:
 
  风管的颤动。因为风管材料是镀锌板或者是金属材料,在施工时要严峻按照施工检验标准选择钢板厚度和施工工艺,比如风管制作差错、平直度、风管加固、支吊架选择及制作设备等等。到了施工阶段,出风口尽量不要挨近设备。电扇前后尽量都有5米以上的长度。假定可以增加弯头数目也可以下降噪音,风口加装过滤网,噪音操控作用也很好。
 
  Flutter of air duct. Because the material of air duct is galvanized sheet or metal material, the thickness of steel plate and construction technology should be strictly selected according to construction inspection standards, such as air duct errors, flatness, air duct reinforcement, support and hanger selection and production equipment, etc. At the construction stage, the outlet should not be close to the equipment as far as possible. The length of the electric fan should be more than 5 meters before and after it. It is assumed that the number of elbows can be increased and the noise can be reduced. A filter is installed in the tuyere, and the noise control function is also very good.
