實驗室通風管道的正確安裝對于確保通風系統運行有效和節能，是一個很重要的環節。今天
濟南通風管道廠家就來講一下實驗室通風管道安裝時需要避免的一些問題。
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.
風管安裝前未清除內部雜物
Internal sundries are not removed before installation of air duct
風管安裝前應清除內、外雜物，并做好清潔和成品，施工后及時封堵管口，如不清除雜物，將會造成系統阻力增大，嚴重時堵塞過濾網和管道。風管系統安裝后不按規定作漏光、漏風檢查和試驗
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
漏光或漏風量測定是對通風空調施工質量的一項檢驗措施，必須嚴格按要求規范進行檢驗，若風管系統安裝后不按規定作漏光、漏風檢查和試驗，可能會造成系統大量漏風，使整個系統和項目工程達不到使用要求，增加不必要的返工和浪費，同時也浪費了能源。
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.
風閥安裝位置不便于操作和檢修
The installation position of air valve is not convenient for operation and maintenance
各類風閥應安裝在便于操作及檢修的部位，吊頂或井道內設置檢修口。
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.
風管支、吊架間距過大
The spacing between air duct supports and hangers is too large
風管支吊架的間距過大，會造成風管變形，影響感官效果；如果膨脹螺栓使用不當，風管的重量超過吊點的承載力甚至會造成風管墜落，出現施工安全隱患。
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.
風管系統采用組合式法蘭連接時接口漏風
When the air duct system adopts combined flange connection, the interface leaks
接口漏風不符合質量標準，將會造成整個系統風量損失過大，無法滿足風量要求，并造成能源嚴重浪費。磚結構風道與金屬風管連接處未設預埋件或密封縫隙過大或連接處不嚴密
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、矩形短管安裝時產生扭曲
The flexible short pipe and rectangular short pipe are twisted during installation
短管扭曲易產生質量問題，也影響美觀，在安裝時需要特別留意。
The distortion of the short pipe is easy to cause quality problems, and also affects the aesthetics. Special attention should be paid during installation.
防排煙系統的柔性短管采用易燃材料
Flexible short pipe of smoke control system is made of combustible materials
防排煙系統柔性短管的制作材料必須為不燃材料，且應選用防腐、防潮、不透氣、不易霉變的柔性材料。用于空調系統的應采取防止結露的措施；用于空調凈化系統的還應是內壁光滑、不易產生塵埃的材料。
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.
風管系統不設置防擺支架
The air duct system is not equipped with anti-swing support
在實驗室通風管道安裝時，當水平懸吊的主、干風管長度超過20m時，應設置防止擺動的固定點，每個系統不應少于1個，如果不設置，則系統運行時會產生風管移動、震動。
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.
