在通风管道安装时经常遇见哪些问题

发布人:http://www.fggsfs.com   发布时间:2019-05-05 17:30:16

  在建筑业快速发展的现在,高层建筑越来越多,为了保护在内工作人员的身体健康,通风管道的运用也多了起来,在给通风管道加工时,有很多事项要注意,下面主要是一些常见的问题:

  With the rapid development of the construction industry, there are more and more high-rise buildings. In order to protect the health of staff members, the use of ventilation pipes has increased. When processing ventilation pipes, there are many things to pay attention to. The following are mainly some common problems:

  通风管道加工的过程中应该尽量避免出现纵向接缝,但是绝对不能出现横向接缝。而且通风管道的咬口缝和四角的缝隙处,需要按照设计洁净等级要求,然后还要采用密封胶将其堵严。另外通风管道板材的连接缝的密封面应该设在通风管道壁的正压侧。

  Longitudinal joints should be avoided as far as possible in the process of ventilation pipeline processing, but transverse joints should never appear. Moreover, the bite seam and the corner seam of the ventilation pipeline need to be sealed with sealant according to the requirements of the design cleanliness grade. In addition, the sealing surface of the connection joint of the ventilation pipe sheet should be located at the positive pressure side of the ventilation pipe wall.

  加工的时候,不能在通风管道内部设置加固框或者加固筋,因为这样对于通风管道的质量会造成一定的影响。

  When processing, it is not possible to set reinforcement frames or reinforcement bars inside the ventilation pipeline, because this will have a certain impact on the quality of the ventilation pipeline。

  通风管道加工不能采用S型插条和C型直角插条的连接方式,另外对于一些特殊的通风管道来说,还不能采用按扣式的咬口。

  The connection of S-type and C-type right-angle slots can not be used in the processing of ventilation pipes. In addition, for some special ventilation pipes, the button-type bite can not be used.

  通风管道制作完毕之后,还要用清洗液进行清洗,只有达到清洗标准之后,才可以及时封口。

  After the production of ventilation pipes, they should be cleaned with cleaning fluid。 Only after meeting the cleaning standards, can they seal in time。

  如果是彩色涂层钢板通风管道的话,应该保持内壁是光滑的,而且通风管道加工的过程中,还不能将涂层损坏,若是出现损坏的部位,需要用环氧树脂涂刷在表面即可。另外通风管道加工的过程中,还要做好防腐蚀措施,不能使用抽芯铆钉,而且在通风管道零件装配的时候,这些零件都要经过镀锌处理才行。

  If it is a color coated steel ventilation pipe, the inner wall should be kept smooth, and in the process of ventilation pipe processing, the coating can not be damaged, if there are damaged parts, it is necessary to use epoxy resin to coat the surface. In addition, anti-corrosion measures should be taken in the process of ventilation pipeline processing. Core-pulling rivets should not be used. Moreover, when the parts of ventilation pipeline are assembled, they must be galvanized.

  管道通风中的的噪音控制方法

  Noise Control Method in Pipeline Ventilation1、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:通风管道与传统砖砌通风道比,能节约工程造价40%左右;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;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;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;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。

  2。 Low cost: ventilation duct can save about 40% of the project cost compared with traditional brick ventilation duct; 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。 Planning flexible network: ventilation duct can adjust the standard standard of pipeline at any time according to the size of the reserved tunnel; 5。 Planning together: ventilation duct's design A smoke check valve and a fire barrier door are installed on the opening to prevent cross-odor and cross-fire。 6。 The construction is simple: the indoor space is increased, the airproof is good, the smoke and odor are not returned, and the indoor environment can be greatly improved。

极速时时彩官网  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。

极速时时彩官网  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.

  风机的动静。处理方法我们一般可装消声器处理风管zhong风的冲突声。一般在规划阶段就要考虑噪声的问题,规划操控好管内风速,防止风声啸叫以下是一些履历。

  The movement of the fan. In general, we can install mufflers to deal with the conflict sound of wind pipe zhong. In general, the problem of noise should be considered in the planning stage. To control the wind speed in the pipe and prevent the wind from screaming, the following are some resumes.

  1操控出风、回风间隔,防止空气对流时自激表象和小循环空间。

  1. Manipulate the air outlet and return interval to prevent self-excitation and small circulation space during air convection.

  2、螺旋风管风机叶轮体系动平衡校调合理正常正负不大于5丝的高低。

  2. The dynamic balance adjustment of the impeller system of the spiral duct fan is reasonable and the positive and negative values are not more than 5 wires.

  3、软接头设备标准,防止软接帆布松垮发生风阻而形成风噪。

  3. Standard of soft joint equipment to prevent wind resistance from loosening of soft joint canvas and wind noise.

  4、悬挂选用趁便绷簧避震专职的连接器,减轻作业时因扭力发生的跳动或共频。

  4. The suspension adopts the full-time connector of the tension spring shock absorber to alleviate the jump or common frequency caused by the torsion during the operation.

极速时时彩官网  5、螺旋风管风道转角尽量削减。

  5. Reduce the angle of helical duct as far as possible.
