实验室通风管道的正确安装对于确保通风系统运行有效和，是一个很重要的环节。今天
济南通风管道厂家就来讲一下实验室通风管道安装时需要避免的一些问题。
The correct installation of the ventilation duct in the laboratory is a very important link to ensure the effective operation and energy saving of the ventilation system. Today, Jinan ventilation duct manufacturer will talk about some problems that need to be avoided during the installation of laboratory ventilation duct.
风管安装前未内部杂物
Internal sundries are not removed before installation of air duct
风管安装前应内、外杂物，并做好清洁和成品，施工后及时封堵管口，如不杂物，将会造成系统阻力增大，严重时堵塞过滤网和管道。风管系统安装后不按规定作漏光、漏风检查和试验
Before the installation of the air duct, the internal and external sundries should be removed, and the cleaning and finished products should be done. After the construction, the pipe orifice should be blocked in time. If the sundries are not removed, the system resistance will increase, and the filter screen and pipe will be blocked in serious cases. The air duct system is not checked and tested for light and air leakage after installation according to regulations
漏光或漏风量测定是对通风空调施工质量的一项检验措施，必须严格按要求规范进行检验，若风管系统安装后不按规定作漏光、漏风检查和试验，可能会造成系统大量漏风，使整个系统和项目工程达不到使用要求，增加不必要的返工和浪费，同时也浪费了能源。
The measurement of light leakage or air leakage is an inspection measure for the construction quality of ventilation and air conditioning. The inspection must be carried out in strict accordance with the requirements and specifications. If the air duct system is not checked and tested for light leakage and air leakage after installation, it may cause a large amount of air leakage in the system, make the whole system and project process fail to meet the use requirements, increase unnecessary rework and waste, and also waste energy.
风阀安装位置不便于操作和检修
The installation position of air valve is not convenient for operation and maintenance
各类风阀应安装在便于操作及检修的部位，吊顶或井道内设置检修口。
All kinds of air valves shall be installed at the position convenient for operation and maintenance, and the manhole shall be set in the ceiling or hoistway.
风管支、吊架间距过大
The spacing between air duct supports and hangers is too large
风管支吊架的间距过大，会造成风管变形，影响感官效果；如果膨胀螺栓使用不当，风管的重量超过吊点的承载力甚会造成风管坠落，出现施工隐患。
Excessive spacing between air duct supports and hangers will cause air duct deformation and affect sensory effect; If the expansion bolt is not used properly, the weight of the air duct will exceed the bearing capacity of the lifting point, and even cause the air duct to fall, resulting in potential construction safety hazards.
风管系统采用组合式法兰连接时接口漏风
When the air duct system adopts combined flange connection, the interface leaks
接口漏风不符合质量标准，将会造成整个系统风量损失过大，无法满足风量要求，并造成能源严重浪费。砖结构风道与金属风管连接处未设预埋件或密封缝隙过大或连接处不严密
If the air leakage at the interface does not meet the quality standard, the air volume loss of the whole system will be too large to meet the air volume requirements and cause serious waste of energy. The connection between brick structure air duct and metal air duct is not equipped with embedded parts or the sealing gap is too large or the connection is not tight
柔性短管、矩形短管安装时产生扭曲
The flexible short pipe and rectangular short pipe are twisted during installation
短管扭曲易产生质量问题，也影响美观，在安装时需要特别留意。
The distortion of the short pipe is easy to cause quality problems, and also affects the aesthetics. Special attention should be paid during installation.
防排烟系统的柔性短管采用易燃材料
Flexible short pipe of smoke control system is made of combustible materials
防排烟系统柔性短管的制作材料必须为不燃材料，且应选用防腐、防潮、不透气、不易霉变的柔性材料。用于空调系统的应采取防止结露的措施；用于空调净化系统的还应是内壁光滑、不易产生尘埃的材料。
The flexible short pipe of smoke control and exhaust system must be made of incombustible materials, and flexible materials that are resistant to corrosion, moisture, air permeability and mildew shall be selected. For air conditioning system, measures shall be taken to prevent condensation; The materials used for air conditioning purification system shall also be materials with smooth inner wall and not easy to generate dust.
风管系统不设置防摆支架
The air duct system is not equipped with anti-swing support
在实验室通风管道安装时，当水平悬吊的主、干风管长度超过20m时，应设置防止摆动的固定点，每个系统不应少于1个，如果不设置，则系统运行时会产生风管移动、震动。
When installing the ventilation duct in the laboratory, when the length of the main and main air ducts suspended horizontally exceeds 20m, fixed points shall be set to prevent swing. Each system shall not be less than 1. If not set, the air duct will move and vibrate when the system is running.
Some problems to be avoided during the installation of the ventilation duct in the laboratory will be explained here. If you have a need for this, you can contact us at any time to purchase.
