    来源: 浏览: 发布日期:2018-12-17
    跟着现代试验室通风柜的日益增多。试验室人员怎么正确安全的运用试验室通风柜?怎么正确的保护试验室通风柜?
    With the increasing number of ventilators in modern laboratories. How do lab personnel use the lab ventilator correctly and safely? How to protect the laboratory ventilator correctly?
    成为了试验室管理人员头痛的问题。试验室通风柜是试验室设备中的重要组成部分,在科学的试验室环境中,杰出的通风作用关于创造安全洁净的试验室环境、确保试验条件的科学性、可靠性以及试验过程中的安全性非常重要;
    It has become a headache for laboratory managers. Laboratory ventilation cabinet is an important part of laboratory equipment. In scientific laboratory environment, outstanding ventilation function is very important for creating safe and clean laboratory environment, ensuring the scientificity, reliability of test conditions and safety in the process of test.
    在咱们运用试验室通风柜时,要注意以下几点:
    When we use the laboratory ventilator, we should pay attention to the following points:
    1、室内空气温度在-5℃至+40℃之间,24小时平均值不超越+25℃;
    1. The indoor air temperature ranges from - 5 to + 40 and the 24-hour average does not exceed + 25 C.
    2、试验室内在不运用试验室通风柜时也要经常通风,这样对试验人员的身体健康有益;
    2. The laboratory should be ventilated regularly when the laboratory ventilator is not used, which is beneficial to the health of the experimenters.
    3、当2个以上的试验室通风柜共同运用1个风机时,为防止操作失误或不当,风机的 “开”“关”只能由1个操作人员来操控;如另外一个试验室通风柜暂时不运用或要中止运用,可运用风量调节阀来关闭通风口;防止彼此重复“开”“关”风机,这样不但对风机的寿数产生损害,对试验也不精确。
    3. When more than two laboratory ventilators use one fan together, in order to prevent misoperation or improper operation, the "on" and "off" of the fan can only be controlled by one operator; if another laboratory ventilator is temporarily not in use or to stop using, the ventilation valve can be used to close the vent; to prevent the repetition of "on" and "off" of the fan, which is not only for the fan. Life is damaged and the test is not accurate.
    4、试验室通风柜在运用时,防止人员走动带来的逆流风向对试验室通风柜的搅扰;
    4. In the operation of the laboratory ventilator, the disturbance of the countercurrent wind direction caused by the movement of personnel to the laboratory ventilator should be prevented.
    5、试验室通风柜在运用时,每2小时进行10分钟的补风(即开窗通风);运用时间超越5小时的,要打开窗户,防止室内呈现负压。
    5. When the laboratory ventilator is in use, 10 minutes of air supply (i.e. window ventilation) should be carried out every 2 hours; if the use time exceeds 5 hours, the windows should be opened to prevent negative pressure in the room.
