实验室通风系统是实验室中非常重要的一个系统，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。今天我们就来看一下实验室通风管道安装时需要避免的一些问题。

The laboratory ventilation system is a very important system in the laboratory, and the correct installation of laboratory ventilation ducts is a crucial step in ensuring the effective operation and energy-saving of the ventilation system. Today we will take a look at some issues that need to be avoided when installing ventilation ducts in the laboratory.

1、风管安装前未内部杂物

1. Failure to remove internal debris before installing the 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。

Before installing the air duct, internal and external debris should be removed, and cleaning and finished products should be done. After construction, the pipe mouth should be sealed in a timely manner. If the debris is not removed, it will cause an increase in system resistance, and in severe cases, the filter screen and pipeline will be blocked.

2、风管系统安装后不按规定作漏光、漏风检查和试验

2. Failure to conduct light and air leakage checks and tests as required after the installation of the air duct system

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。

Measurement of light or air leakage is an inspection measure for the quality of ventilation and air conditioning construction, which must be strictly inspected according to the required specifications. If the air duct system is not inspected and tested for light or air leakage according to regulations after installation, it may cause a large amount of air leakage in the system, making the entire system and project project unable to meet the usage requirements, increasing unnecessary rework and waste, and also wasting energy.

3、各类风阀安装位置不便于操作和检修

3. The installation positions of various air valves are 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 types of air valves should be installed in areas that are easy to operate and maintain, and maintenance openings should be set up in suspended ceilings or shafts.

4、风管支、吊架间距过大

4. Excessive spacing between air duct supports and hangers

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 can cause deformation of the air duct and affect sensory effects; If the expansion bolts are not used properly, the weight of the air duct may exceed the bearing capacity of the lifting point and even cause the air duct to fall, posing a construction safety hazard.

5、风管系统采用组合式法兰连接时接口漏风

5. When the air duct system adopts a combination flange connection, the interface leaks air

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。

If the interface air leakage does not meet the quality standards, it will cause excessive air loss in the entire system, fail to meet the air volume requirements, and cause serious energy waste.

6、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。

6. The connection between the brick structure air duct and the metal air duct is not equipped with embedded parts, or the sealing gap is too large or the connection is not tight.

7、柔性短管、矩形短管安装时产生扭曲。

7. Twisting occurs during the installation of flexible and rectangular short pipes.

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。

Twisted short pipes can easily cause quality problems and also affect aesthetics, so special attention should be paid during installation.

8、防排烟系统的柔性短管采用易燃材料

8. The flexible short pipes of the smoke exhaust system are made of flammable 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 production material of flexible short pipes for smoke control and exhaust systems must be non combustible materials, and flexible materials that are corrosion-resistant, moisture-resistant, breathable, and not easily moldy should be selected. Measures to prevent condensation should be taken for air conditioning systems; The materials used for air conditioning purification systems should also have smooth inner walls and are not prone to dust generation.

9、风管系统不设置防摆支架。

9. The air duct system is not equipped with anti swing brackets.

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 ventilation ducts in the laboratory, when the length of the main and main air ducts suspended horizontally exceeds 20m, fixed points should be set to prevent swinging. Each system should have at least one fixed point. If not set, the air ducts will move and vibrate during system operation.
