来源:http://www.topslmdwn.com 日期:2020-02-01 发布人:admin

在市场高速发展的趋势下,对通风管道的需求越来越高,在各个行业中,它已经成为人们生活中必不可少的一部份。通风管道系统加工的布局平整美观、简单紧凑、安装、操作、检修的方便等因素决定管道系统的合理性,应满足平时排风与火灾时排烟的要求。那么通风管道安装的系统布局一般有哪些步骤?需要注意些什么?下面来听听通风管道加工的技术人员是怎么说的吧?
With the rapid development of the market, the demand for ventilation pipe is higher and higher. In various industries, it has become an essential part of people's life. The layout of the processing of the ventilation pipeline system is flat and beautiful, simple and compact, and the installation, operation, maintenance and other factors determine the rationality of the pipeline system, which should meet the requirements of ventilation and smoke exhaust in case of fire. So what are the general steps of the system layout for the installation of ventilation ducts? What should we pay attention to? Now let's listen to the technical personnel of ventilation pipe processing?
通风管道加工的系统布局需遵循以下几点:
The following points shall be followed for the system layout of ventilation pipe processing:
一、系统网的布局形式
1、 Layout form of system network
为方便管网的管理和运行调节,管网系统不宜过大,同一系统有多个分支管时,应将这些分支管分级控制,且同一系统的吸气点不宜过多,一定要注意各支管的压力平衡。常用的管网布局方式有干管配管、个别配管、环状配管3种。
In order to facilitate the management and operation regulation of the pipe network, the pipe network system should not be too large. When there are multiple branches in the same system, the branches should be controlled by levels, and the suction points of the same system should not be too many. It is necessary to pay attention to the pressure balance of each branch pipe. There are three types of pipe network layout: main pipe, individual pipe and ring pipe.
二、布局的原则
2、 Principles of layout
1、通风管道安装系统的铺设原则
1. Laying principle of ventilation pipe installation system
管道铺设分明装、暗装,一般采用明装。因为明装以便于检修,在无法采用明装时考虑暗装方式,管道尽可能的集中成列,尽量沿墙或柱子平行铺设,若管径大或保温应布局在靠墙侧。一般两根管道平行布局时,间距不小于100~200mm。
The pipeline shall be installed in a clear and concealed manner, and generally installed in an open manner. Because the open installation is convenient for maintenance, the concealed installation method shall be considered when the open installation is not available. The pipes shall be arranged in rows as far as possible, and shall be laid parallel to the wall or column as far as possible. If the pipe diameter is large or the insulation shall be arranged on the wall side. Generally, when two pipelines are arranged in parallel, the spacing shall not be less than 100-200mm.
2、通风管道加工系统的连接原则
2. Connection principle of ventilation pipe processing system
在以焊接为主要连接方式方法的管道中,应设置足够数量的法兰连接,在以螺纹为主的连接管道中应设置足够的活接头,以便宜于安装、拆卸、检修。
In the pipeline with welding as the main connection method, a sufficient number of flange connections shall be set, and in the pipeline with thread as the main connection method, a sufficient number of movable joints shall be set, which is cheaper than installation, disassembly and maintenance.
3、通风管道加工系统的支撑原则管道不宜与阀件直接支撑在设备上,应单独设置支架或吊架,管道的焊缝位置应在施工方便或受力较小的地方,焊缝不得位于支架处且距离不小于200mm。
3. The support principle of the processing system of the ventilation pipe is that the pipe should not be directly supported on the equipment with the valve, and the support or hanger should be set separately. The weld position of the pipe should be at the place where the construction is convenient or the stress is small, and the weld should not be at the support and the distance should not be less than 200 mm.
4、不同含尘气体性质不同,则净化的分段处理应不同。
4. If the properties of different dust containing gases are different, the subsection treatment of purification should be different.
当污染源多时可以集中在一个净化系统中,也可分为几个系统,但出现污染物混合会引起燃烧、爆炸危险、不同温度和湿度的气体,混合后出现管道内结露、粉尘或气体性质不同,影响回收或净化效率的。
When there are many pollution sources, they can be concentrated in one purification system or divided into several systems. However, when pollutants are mixed, it will cause combustion, explosion hazard, gases with different temperature and humidity. After mixing, condensation, dust or gas properties in the pipeline will be different, which will affect the recovery or purification efficiency.
5、通风管道加工系统布局中要保证整体系统的漏损小,确保吸尘口的有足够的风量。
5. In the layout of the ventilation pipe processing system, it is necessary to ensure that the leakage of the whole system is small and that the dust collector has sufficient air volume.
6、通风管道加工系统布局要减小阻力。
6. The layout of the ventilation pipe processing system should reduce the resistance.
