通风管道加工施工前要做哪些准备?

发布时间:2019/04/16

关于施工十分注重,下面就简介一下施工之前要做的准备:
  As for the construction, we pay great attention to it. Here is a brief introduction of the preparation before the construction.
  关于比拟复杂的民用建筑,在设计阶段,各工种(暖通、给水排水,供电照明与济南螺旋风管加工)首先应协商好空间分隔,定出每种管道的标高范围。普通状况下不得越出给本人规则的界线。遇有个别管段要越界时应与其他工程协商。
  In the design stage of a comparatively complex civil building, each type of work (HVAC, water supply and drainage, power supply and lighting, and processing of Jinan spiral duct) should first negotiate space separation and determine the elevation range of each type of pipeline. Normally, you must not go beyond the boundaries of your own rules. Consultation with other projects should be conducted when there is an individual pipeline crossing the boundary.
  (1)当风管与风机衔接时,应在进出风口处加软接头,其软接头的断面尺度应与风机进出风口共同。软管接头普通可采用帆布、人造革等资料,济南螺旋风管软管长度不宜小于200,松紧度应适合,柔性软管可缓冲风机的振荡。
  (1) When the duct is connected with the fan, a soft joint should be added at the inlet and outlet of the fan. The cross-sectional dimension of the soft joint should be the same as that of the inlet and outlet of the fan. The hose joint can generally use canvas, artificial leather and other information. The length of the hose of Jinan spiral duct should not be less than 200, the tightness should be suitable, and the flexible hose can cushion the vibration of the fan.
  (2)当风道与除尘设备、济南螺旋风管加热设备等衔接前,应待设备安装终了后,按理论测绘的图纸中止预制和安装。
  (2) Before connecting the air duct with the dust removal equipment and the heating equipment of Jinan spiral air duct, the prefabrication and installation shall be discontinued according to the theoretical mapping drawing after the installation of the equipment.
  (3)济南通风管道安装时,进、出风日宜在风道预制时开出洞口,如需在安装终了的风道上现开风口,其接口处应严密。
  (3) When installing Jinan ventilation pipeline, the inlet and outlet should be opened when the duct is prefabricated. If the outlet is to be found in the duct after installation, the interface should be tight.
  (4)当运送含凝结水或含湿量较大的气体时,其程度管道宜设有坡度,并在低点处接排水管。济南螺旋风管安装时风道底部不宜呈现纵向接缝,对底部有接缝处应中止密封处置。
  (4) When transporting gas with condensate water or high moisture content, the gradient of the pipeline should be set and the drainage pipe should be connected at the low point. When installing the spiral duct in Jinan, the longitudinal seam should not appear at the bottom of the duct, and the sealing treatment should be discontinued at the seam at the bottom.

  (5)对运送易燃、易爆气体的钢板风道,在风道衔接法兰处应安装跨接线,并与静电接地网衔接。
  (5) For steel plate air ducts transporting flammable and explosive gases, a cross connection shall be installed at the flange of the air duct connection and connected with the electrostatic grounding grid.
  局部通风系统又分为局部进风和局部排风两大类,它们都是应用局部气流,使局部工作地点不受有害物的污染,构成良好的空气环境。
  Local ventilation system can be divided into local air intake and local air exhaust. Both of them use local air flow to protect local working places from harmful pollutants and form a good air environment.
  1)风管穿过建筑物的楼板或隔墙时应设置壁厚不小于1.6mm的防护套管,且在风管与防护套管之间采用对人体无害的不燃柔性资料封堵。
  1) When the duct passes through the floor or partition wall of a building, a protective sleeve with a wall thickness of not less than 1.6 mm shall be installed, and a non-flammable flexible data blocking between the duct and the protective sleeve sleeve shall be adopted.
  2)风管装置时严禁直接攀爬倚靠风管。必要时应运用1000mm×2000mm左右的两块木板垫脚(增加受力面积),交替行进,保证平安。
  2) It is strictly forbidden to climb and lean on the duct directly when the duct is installed. When necessary, we should use two wooden board pads (about 1000mm * 2000mm) to increase the stress area, alternately travel, to ensure safety.
  3)济南螺旋风管沿墙体或楼板装置时,距墙面、楼板宜大于100mm。无吊顶明装风管的装置位置与标高误差不应大于10mm。与设备衔接法兰的螺栓应平均拧紧,其螺母宜在同一侧。
  3) When the spiral air duct is installed along the wall or floor in Jinan, the distance between the spiral air duct and the wall or floor should be greater than 100 mm. The error of installation position and elevation of open air duct without ceiling should not be greater than 10 mm. The bolts of the flange connecting with the equipment should be tightened evenly, and the nuts should be on the same side.
