  • 实验室通风系统在安装避免哪些问题?
    来源:http://www.jnyhrs.com 浏览: 发布日期:2020-10-08
    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节能,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 correct installation of ventilation duct in laboratory is a very important link to ensure the effective operation and energy saving of ventilation system. Today, let's take a look at some of the problems that need to be avoided in the installation of laboratory ventilation ducts.
    01风管安装前未清除内部杂物
    The internal sundries of 01 air duct were not removed before installation
    风管安装前应清除内、外杂物,并做好清洁和成品,施工后及时封堵管口,如不清除杂物,将会造成系统阻力增大,严重时堵塞过滤网和管道。
    Before the installation of air duct, the internal and external sundries should be removed, and the cleaning and finished products should be done well. After construction, the pipe orifice should be blocked in time. If the sundries are not removed, the system resistance will be increased, and the filter screen and pipeline will be blocked in serious cases.
    02风管系统安装后不按
    02 after the installation of air duct system, do not press
    规定作漏光、漏风检查和试验
    Inspection and test of light and air leakage are specified
    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, which must be inspected in strict accordance with the requirements. If the light leakage and air leakage inspection and test are not carried out according to the regulations after the installation of the air duct system, a large amount of air leakage may be caused, making the whole system and project project project unable to meet the use requirements, increasing unnecessary rework and waste, and also wasting energy.
    03风阀安装位置不便于操作和检修
    The installation position of 03 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 shaft.
    04风管支、吊架间距过大
    04 the distance between supports and hangers of air duct 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至会造成风管坠落,出现施工安全隐患。
    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, which may cause the construction safety hidden danger.
    05风管系统采用组合式
    05 air duct system adopts combined type
    法兰连接时接口漏风
    Air leakage of interface during flange connection
    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 air leakage of 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 energy waste.
    06砖结构风道与金属风管连接处
    06 joint between brick structure air duct and metal air duct
    未设预埋件或密封缝隙过大或连接处不严密
    No embedded parts are set, sealing gap is too large or joint is not tight
    风管与砖、混凝土风道的连接接口,应顺着气流方向插入,并应采取密封措施,风管穿出屋面处应设有防雨装置;在施工中必须按要求在砖、结构风道与金属风道连接处设置预埋件,或要求土建单位配合进行堵封,确保连接严密。
    The connection interface between air duct and brick and concrete air duct shall be inserted along the direction of air flow, and sealing measures shall be taken. Rain proof device shall be set at the place where the air duct passes through the roof; during construction, embedded parts shall be set at the joint of brick and structural air duct and metal air duct, or the civil engineering unit shall be required to cooperate for sealing to ensure tight connection.
    07柔性短管、矩形短管安装时产生扭曲
    07 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。
    Distortion of the short pipe is easy to cause quality problems and also affect the appearance. Special attention should be paid to it when installing.
    08防排烟系统的柔性短管采用易燃材料
    08 the flexible short pipe of smoke control system is 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 flexible short pipe of smoke control system must be made of non combustible material, and the flexible material with anti-corrosion, moisture-proof, airtight and not easy to mildew should be selected. For air conditioning system, measures should be taken to prevent condensation; for air conditioning purification system, materials with smooth inner wall and not easy to produce dust should be used.
    09风管系统不设置防摆支架
    09 air duct system without 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。
    During the installation of ventilation duct in laboratory, when the length of horizontal suspension main and main air duct is more than 20m, fixed points shall be set to prevent swing, and each system shall not be less than 1. If not, air duct movement and vibration will occur during system operation.
