防火卷帘门是如何工作的?

来源:http://www.jnhsjlm.com 日期:2020-05-18 发布人:admin
  消防防火卷帘门属于消防安装工程的内容,它的重要性自然是不用再重复叙述了,防火卷帘门是通过怎样的步骤体现它的重要作用呢,这就不得不说说防火卷帘门的使用原理了。
  The fire-fighting rolling shutter door belongs to the content of fire-fighting installation engineering, its importance is naturally not to repeat the description, what steps does the fire-fighting rolling shutter door embody its important role, so we have to talk about the use principle of the fire-fighting rolling shutter door.
  防火卷帘门(这里说的是电动)由传感器提供触发信号给控制系统,控制系统根据快速卷帘门的当前位置状况发出指令给变频器,启动驱动电机使门帘快速上升,车辆行人通过后再驱动门帘自动下降,关闭进入通道,直到下一个开门信号到来时再次打开.顾名思义,快速卷帘门升降速度非常快,不能像钢质卷闸门一样直接启动停止,一般需要变频器来控制电机的转速.上升时自然是速度越快越好,当门帘上升快到位时(20cm左右)还需要有一个减速缓冲停止过程,以防止门帘撞击轨道或者夹伤人,缓冲还能降低噪音,这也是衡量快速卷帘门性能好坏的一个标准。
  The fire shutter door (electric here) is provided with trigger signal by the sensor to the control system. The control system sends command to the frequency converter according to the current position of the fast shutter door, starts the driving motor to make the curtain rise rapidly, drives the curtain to fall automatically after passing by the vehicle and pedestrian, closes the access channel, and opens again until the next door opening signal comes The fast rolling shutter door can't be started and stopped directly like the steel rolling shutter. Generally, a frequency converter is needed to control the speed of the motor. The faster the speed is, the better. When the door curtain is fast to rise (about 20cm), a deceleration buffer is needed to stop the process, so as to prevent the curtain from hitting the track or pinching people. The buffer can also reduce the noise, which is also a measure of fast speed A standard for the performance of roller shutter doors.

  防火卷帘门是在钢质卷帘的基础上,将传动部件加以改造,配以防火电器等设备,从而实现防火作用:防火电机由防火电控箱控制,通过变速装置驱动卷轴使卷帘门起闭,停电时也可使用防火电机上的手动摇柄,可实现手动操作。在机械相对运动处,采用联轴器代替链轮传动,道轨内摩擦处镶嵌铜板或尼龙。更适合于使用或保管可燃性气体、挥发性化学药品等具有高发火性物品的工厂和仓库等出现或可能出现爆炸的火灾危险的环境。
  On the basis of steel rolling shutter, the transmission parts of the fireproof rolling shutter are modified and equipped with fireproof electrical appliances and other equipment, so as to realize the fireproof function: the fireproof motor is controlled by the fireproof electric control box, and the rolling shutter is opened and closed by the transmission device, and the manual handle on the fireproof electric machine can also be used in case of power failure, so as to realize the manual operation. In the relative movement of the machine, the coupling is used instead of the sprocket drive, and the friction part in the track is inlaid with copper plate or nylon. It is most suitable for factories and warehouses that use or keep inflammable gases, volatile chemicals and other highly flammable substances, etc. in which there is or may be explosion.
  已安装好的消防卷帘门属于建筑消防设施,不得随意拆卸或更改。如要进行相关操作,先需对作业部位绘制好平面布局图,标明以前情况及更改后的布局情况,因为稍有损害可能会引起防火卷帘门故障,很容易发生事故,造成不必要的损失。
  The installed fire rolling shutter door belongs to the fire-fighting facilities of the building and shall not be dismantled or changed at will. If you want to carry out relevant operations, you need to draw a good layout plan for the operation site, indicating the previous situation and the changed layout, because a little damage may cause the fire shutter failure, it is easy to cause accidents, resulting in unnecessary losses.
