通风管道加工如何安装要符合的规定?

发布时间:2021/03/29

吊架安装对管道起着支承重量、平衡介质反力、限制位移和防止震动等作用。因此就需要施工人员了解安装吊架的规定,才能更好的完成通风管道施工工程,
The installation of hanger plays the role of supporting weight, balancing medium reaction, limiting displacement and preventing vibration. Therefore, it is necessary for the construction personnel to understand the installation of hangers in order to better complete the ventilation pipeline construction project,
通风管道加工安装要符合的规定:
Requirements for processing and installation of ventilation pipes:
(1)管道风机采用减震吊架安装时,风机与减震吊架连接紧密,牢固可靠;采用支拖架安装时,风机与减震器及支架、托架连接紧密,稳固可靠。
(1) When the pipeline fan is installed with the shock absorption hanger, the fan and the shock absorption hanger are closely connected, firm and reliable; when the support trailer is used for installation, the fan and the shock absorber, support and bracket are closely connected, firm and reliable.
(2)离心风机与减震台座接触紧密,螺栓拧紧,并有防松装置。
(2) The centrifugal fan is in close contact with the shock absorption pedestal, the bolts are tightened, and there is a locking device.
(3)通风管道厂家告诉大家风机试运转时,叶轮旋转方向正确,经不少于2H运转后,滑动轴承温升不超过35度,尽量温度不超过70度;滚动轴承温升不超过40度,尽量温度不超过80度。
(3) The ventilation duct manufacturer told us that during the trial operation of the fan, the rotation direction of the impeller is correct. After running for no less than 2 hours, the temperature rise of the sliding bearing should not exceed 35 degrees, and the temperature should not exceed 70 degrees as far as possible; the temperature rise of the rolling bearing should not exceed 40 degrees, and the temperature should not exceed 80 degrees as far as possible.
当前普遍存在的问题是成品通风道燃烧性能和耐火极限未经国家有关部门检测,山东通风管道加工且部分通风道材料的燃烧性能、管壁厚度不符合要求。
At present, the common problems are that the combustion performance and fire resistance of the finished ventilation duct have not been tested by the relevant national departments, and the processing of Shandong ventilation duct, and the combustion performance and wall thickness of some ventilation duct materials do not meet the requirements.
1、风机、空调机组、风机盘等设备的支、吊架设计要求设置隔振器,其品种、规格应符合设计及产品技术文件要求。
1. The supports and hangers of fans, air conditioning units, fan panels and other equipment shall be designed with vibration isolators, and their varieties and specifications shall meet the requirements of design and product technical documents.
2、风管垂直安装,间距不应大于4m,单根直管至少应有2个固定点。
2. The air duct shall be installed vertically, the spacing shall not be more than 4m, and a single straight pipe shall have at least two fixed points.
3、吊架的螺孔应采用机械加工,吊杆应平直,螺纹完整、光洁。
3. The screw hole of the hanger shall be machined, the hanger rod shall be straight, and the thread shall be complete and smooth.
4、长度超过20m的水平悬吊风管,在山东通风管道时至少设置1个防晃支架。
4. At least one anti sway support shall be set for horizontal suspended duct with length over 20m in Shandong ventilation duct.
5、支吊架不宜设置在风口、阀门、检查门及自控机构处,离风口或插接管的距离不宜小于200mm。
5. The support and hanger should not be set at the air outlet, valve, inspection door and automatic control mechanism, and the distance from the air outlet or plug-in pipe should not be less than 200 mm.
