  • 实验室装潢工程中循环水及排风系统验收准则
    来源: 浏览:次 发布日期:2019-03-20
    实验室装潢之循环水系统的验收:
    Acceptance and acceptance of circulating water system for laboratory renovation:
    1、循环水系统的管道材质及规格应与策计划歧,并在完成正式动土下对其停止系统打压。
    1. The material and specifications of the pipes of the circulating water system should be different from those of the design, and the stopping system should be suppressed after the completion of the construction.
    2、循环水管道应有保温处置,北方地域应有伴热处置,以免冬季不运用时管道冻裂。
    2. Circulating water pipelines should be treated with heat preservation and heat tracing in northern areas, so as not to freeze and crack when they are not used in winter.
    3、循环水系统的阀门及把握回路应与策计划歧。
    3. Valves and control loops of circulating water system should be different from design.
    4、循环水系统试运转上应对其电气回路,含水泵及风机机电停止电气实验(譬如回路的绝缘,譬如机电的绝缘及直流电阻)并留档。
    4. The electrical circuit of the circulating water system should be stopped before commissioning. The water-bearing pump and the fan motor should stop the electrical experiment (for example, the insulation of the circuit, for example, the insulation of the motor and the DC resistance) and be kept in file.
    5、初次试运转应对其一切回路的电压、电流停止测试并做记载(将此类数据移交冤大头作为原始数据留档,在历次检修下停止比对)。
    实验室装潢
    5. The first test run shall stop testing and record all the voltage and current of its circuit (transfer such data to the owner as the original data for archiving, and stop comparing after previous overhauls).
    实验室装潢排风回路的验收:
    Acceptance and acceptance of ventilation circuit for laboratory decoration:
    1、实验室排风管道因气体的特殊性应具备耐腐蚀性,及不燃性(通例实验室中的腐蚀性气体分为有机腐蚀、无机腐蚀,除这以外还有比拟特殊的无机腐蚀譬如盐腐蚀、硫化氢腐蚀等)。
    1. Laboratory exhaust pipes should have corrosion resistance and non-flammability due to the particularity of gas (the corrosive gases in conventional laboratories are divided into organic corrosion and inorganic corrosion, in addition to special inorganic corrosion such as salt corrosion and hydrogen sulfide corrosion).
    2、排风管道需求有震动隔离及把握措施风管的支架防腐应合格(在风机与风管衔接处必需有软衔接衔接,以免震动传送,再是风管的三头、三通或四通处必需有硬性支架,以免震气流震动影响风管的寿命,再是直线段每10米不应少于1和硬性支架,露天风管需思索地域特性,譬如台风、飓风、季风、方向要素)。
    2. The ventilation duct needs vibration isolation and control measures. The bracket of the ventilation duct should be qualified for anti-corrosion. (There must be soft connection at the junction of the ventilator and the ventilation duct to avoid vibration transmission. At the same time, there must be rigid bracket at the three, three or four ends of the ventilation duct to avoid the impact of vibration airflow on the service life of the ventilation duct. At the same time, the straight line should not be less than 1 and rigid bracket per 10 meters, and the outdoor ventilation duct should be considered. Domain characteristics, such as typhoon, hurricane, monsoon, direction elements.
    3、排风管道需求有保温措施,并契合国度准则及策划请求(南方地域会由于地域气候特性,空气湿渡过高与空调温度较低的抵触,易于 构成凝露现象。北方地域会由于冬季极寒,易于 形成风管内部蒸汽凝结成冰附着于风管内壁的现象)。
    3. Exhaust duct needs thermal insulation measures, and conforms to national standards and design requirements (Southern region will be due to regional climate characteristics, high air humidity and low air conditioning temperature conflict, thus constituting condensation phenomenon. Because of the extreme cold in winter, the vapor inside the duct condenses into ice and adheres to the inner wall of the duct.
    4、风管管径及途径,穿越防火分区的风阀、套管、环境采样口地位及封堵应无误。
    4. The diameter and way of air duct, the position and sealing of air valves, sleeves, environmental sampling ports passing through fire protection zones should be correct.
