      防火卷簾門是如何工作的?

      來源:http://www.jnhsjlm.com 日期:2020-05-18 發布人:admin
        消防防火卷簾門屬于消防安裝工程的內容,它的重要性自然是不用再重復敘述了,防火卷簾門是通過怎樣的步驟體現它的重要作用呢,這就不得不說說防火卷簾門的使用原理了。
        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.
        防火卷簾門(這里說的是電動)由傳感器提供觸發信號給控制系統,控制系統根據快速卷簾門的當前位置狀況發出指令給變頻器,啟動驅動電機使門簾快速上升,車輛行人通過后再驅動門簾自動下降,關閉進入通道,直到下一個開門信號到來時再次打開.顧名思義,快速卷簾門升降速度非???,不能像鋼質卷閘門一樣直接啟動停止,一般需要變頻器來控制電機的轉速.上升時自然是速度越快越好,當門簾上升快到位時(20cm左右)還需要有一個減速緩沖停止過程,以防止門簾撞擊軌道或者夾傷人,緩沖還能降低噪音,這也是衡量快速卷簾門性能好壞的一個標準。
        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.

        防火卷簾門是在鋼質卷簾的基礎上,將傳動部件加以改造,配以防火電器等設備,從而實現防火作用:防火電機由防火電控箱控制,通過變速裝置驅動卷軸使卷簾門起閉,停電時也可使用防火電機上的手動搖柄,可實現手動操作。在機械相對運動處,采用聯軸器代替鏈輪傳動,道軌內摩擦處鑲嵌銅板或尼龍。更適合于使用或保管可燃性氣體、揮發性化學藥品等具有高發火性物品的工廠和倉庫等出現或可能出現爆炸的火災危險的環境。
        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.
        已安裝好的消防卷簾門屬于建筑消防設施,不得隨意拆卸或更改。如要進行相關操作,先需對作業部位繪制好平面布局圖,標明以前情況及更改后的布局情況,因為稍有損害可能會引起防火卷簾門故障,很容易發生事故,造成不必要的損失。
        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.
