　　實(shí)驗(yàn)室通風(fēng)系統(tǒng)是實(shí)驗(yàn)室中非常重要的一個(gè)系統(tǒng)，實(shí)驗(yàn)室通風(fēng)管道的正確安裝對(duì)于確保通風(fēng)系統(tǒng)運(yùn)行有效和節(jié)能，是一個(gè)很重要的環(huán)節(jié)。今天我們就來(lái)看一下實(shí)驗(yàn)室通風(fēng)管道安裝時(shí)需要避免的一些問(wèn)題。

　　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 and energy-saving operation of the ventilation system. Today we will take a look at some issues that need to be avoided when installing laboratory ventilation ducts.

　　01  風(fēng)管安裝前未清除內(nèi)部雜物

　　01 Failure to remove internal debris before installing the air duct

　　風(fēng)管安裝前應(yīng)清除內(nèi)、外雜物，并做好清潔和成品，施工后及時(shí)封堵管口，如不清除雜物，將會(huì)造成系統(tǒng)阻力增大，嚴(yán)重時(shí)堵塞過(guò)濾網(wǎng)和管道。

　　Before installing the air duct, internal and external debris should be removed, and cleaning and finishing should be done well. After construction, the pipe mouth should be promptly sealed. If the debris is not removed, it will cause an increase in system resistance, and in severe cases, it may block the filter screen and pipeline.

　　02  風(fēng)管系統(tǒng)安裝后不按規(guī)定作漏光、漏風(fēng)檢查和試驗(yàn)

　　02 Failure to conduct light and air leakage inspections and tests as required after installation of the air duct system

　　漏光或漏風(fēng)量測(cè)定是對(duì)通風(fēng)空調(diào)施工質(zhì)量的一項(xiàng)檢驗(yàn)措施，必須嚴(yán)格按要求規(guī)范進(jìn)行檢驗(yàn)，若風(fēng)管系統(tǒng)安裝后不按規(guī)定作漏光、漏風(fēng)檢查和試驗(yàn)，可能會(huì)造成系統(tǒng)大量漏風(fēng)，使整個(gè)系統(tǒng)和項(xiàng)目工程達(dá)不到使用要求，增加不必要的返工和浪費(fèi)，同時(shí)也浪費(fèi)了能源。

　　Leakage or air leakage measurement is an inspection measure for the construction quality of ventilation and air conditioning, which must be strictly inspected according to the required specifications. If the air duct system is not inspected and tested for leakage and 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 engineering unable to meet the requirements for use, increasing unnecessary rework and waste, and also wasting energy.

　　03   風(fēng)閥安裝位置不便于操作和檢修

　　The installation position of the 03 air valve is not convenient for operation and maintenance

　　各類風(fēng)閥應(yīng)安裝在便于操作及檢修的部位，吊頂或井道內(nèi)設(shè)置檢修口。

　　All types of air valves should be installed in locations that are easy to operate and maintain, with maintenance ports set up in suspended ceilings or shafts.

　　04   風(fēng)管支、吊架間距過(guò)大

　　04 The spacing between air duct supports and hangers is too large

　　風(fēng)管支吊架的間距過(guò)大，會(huì)造成風(fēng)管變形，影響感官效果；如果膨脹螺栓使用不當(dāng)，風(fēng)管的重量超過(guò)吊點(diǎn)的承載力甚至?xí)斐娠L(fēng)管墜落，出現(xiàn)施工安全隱患。

　　The spacing between air duct supports and hangers is too large, which can cause deformation of the air duct and affect the sensory effect; If the expansion bolt is used improperly, 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.

　　05   風(fēng)管系統(tǒng)采用組合式法蘭連接時(shí)接口漏風(fēng)

　　When the 05 duct system adopts a combination flange connection, there is air leakage at the interface

　　接口漏風(fēng)不符合質(zhì)量標(biāo)準(zhǔn)，將會(huì)造成整個(gè)系統(tǒng)風(fēng)量損失過(guò)大，無(wú)法滿足風(fēng)量要求，并造成能源嚴(yán)重浪費(fèi)。

　　Interface air leakage that does not meet quality standards will cause excessive loss of air volume in the entire system, unable to meet air volume requirements, and result in serious energy waste.

　　06   磚結(jié)構(gòu)風(fēng)道與金屬風(fēng)管連接處未設(shè)預(yù)埋件或密封縫隙過(guò)大或連接處不嚴(yán)密

　　The connection between the 06 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

　　07   柔性短管、矩形短管安裝時(shí)產(chǎn)生扭曲

　　Twisting occurs during the installation of flexible short pipes and rectangular short pipes in 07

　　短管扭曲易產(chǎn)生質(zhì)量問(wèn)題，也影響美觀，在安裝時(shí)需要特別留意。

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

　　08   防排煙系統(tǒng)的柔性短管采用易燃材料

　　The flexible short pipe of the 08 smoke control system is made of flammable materials

　　防排煙系統(tǒng)柔性短管的制作材料必須為不燃材料，且應(yīng)選用防腐、防潮、不透氣、不易霉變的柔性材料。用于空調(diào)系統(tǒng)的應(yīng)采取防止結(jié)露的措施；用于空調(diào)凈化系統(tǒng)的還應(yīng)是內(nèi)壁光滑、不易產(chǎn)生塵埃的材料。

　　The production material of flexible short pipes for smoke control systems must be non combustible materials, and flexible materials that are corrosion-resistant, moisture-proof, airtight, and not easily moldy should be selected. Measures to prevent condensation should be taken for air conditioning systems; Materials with smooth inner walls and low dust generation should also be used for air conditioning purification systems.

　　09   風(fēng)管系統(tǒng)不設(shè)置防擺支架

　　09 Duct system does not have anti sway brackets installed

　　在實(shí)驗(yàn)室通風(fēng)管道安裝時(shí)，當(dāng)水平懸吊的主、干風(fēng)管長(zhǎng)度超過(guò)20m時(shí)，應(yīng)設(shè)置防止擺動(dòng)的固定點(diǎn)，每個(gè)系統(tǒng)不應(yīng)少于1個(gè)，如果不設(shè)置，則系統(tǒng)運(yùn)行時(shí)會(huì)產(chǎn)生風(fēng)管移動(dòng)、震動(dòng)。

　　When installing ventilation ducts in the laboratory, if the length of the horizontally suspended main and main air ducts exceeds 20m, fixed points to prevent swinging should be set up, and each system should not be less than 1. If not set up, the air ducts will move and vibrate during system operation.
