The switches and power sockets for fume hoods shall be placed on the outside of the fume hood .

就像我说过的，这是特别有害的物质，在通风柜中才能用。

As I said , it 's a particularly hazardous substance , this is worked with in fume hoods .

产生高反应活性、性质不相容、强毒性气体的通风柜管路不能连接在一起，并且直接排除室外。

Exhausting highly reactive , incompatible or highly toxic materials shall not be manifolded and exhausted directly to the outside .

通风柜的设计要减少静压损失。因此一般在排气口附件采用钟型设计。

Fume hood shall be designed to minimize static pressure loss . Bell shaped exhaust collar configuration shall be provided .

通风柜里面的配件（龙头喷嘴）由黄铜构成，外面环氧树脂喷涂。

Fixtures exposed to hood interior ( i.e.tap nozzle ) shall be made of brass with chemically resistant black vinyl coating .

介绍了实验室通风柜、化验台的通风排气量的计算方法，提出了在冬季采暖新风耗热量大的情况下的补风节能措施。

This paper gathers up many methods and forms of formula in calculating the amount of air-removal through ventilation cabinet in laboratory .

功能：人员及重型落地仪仪设备可址接进入通风柜内，增加操作更利性。

Functions : people heavy console instruments can directly enter into the draught hood , which has increased the convenience of the operation .

每一个通风柜标准配置为一个冷水龙头，此外根据实验室专家要求可以配置最多7个不同的气体龙头。

Each Fume Hood will be equipped with one cold water faucet and maximum to seven various gas faucet according to laboratory specialists'requirement .

通风柜，通风橱的管道要通到屋顶，通风橱内要有水管，水槽。

The pipe of fume hood should upward through the roof . There should be water pipe and water sink in the fume hood .

台面板：材料可由用户选用。柜体：采用美国威盛亚防火板贴面压贴露水河三聚氰氨板组成通风柜外框。

Worktop : Chosen by customer Cabinet : Outline boarders of fume hood adopt American Wilsonart fireproofing veneer and laminate Dew River melamine chipboard .

实验室排气系统包括排气管路、气风机、验室通风柜管道、验室排风罩和特殊存储柜的排气管道。

The laboratory exhaust system includes exhaust duct works , exhaust fan , laboratory fume hood exhaust , laboratory canopy hood and cabinets needed venting .

手持信号灯酸性蓄电池通风柜。该模式适应充电作业特点，改善作业环境，净化效率高，节省风量，节约能源。

These modes are suit for charging works , and they can improve working environment , have high cleaning efficiency , use less wind and energy .

电螺管控制的扰流片扰流板：扰流板应该和内衬材料一致，其引导通风柜气体排除柜外。

Solenoid operated spoiler Baffles : Baffles providing controlled air vectors into and through the fume hood shall be constructed from the same material as the liner .
