   消防电梯是在修建物发作火灾时供消防人员进行救活与救援运用且具有必定功用的电梯。因而,消防电梯具有较高的防火要求,其防火设计十分重要。

   一般电梯均不具有消防功用,发作火灾时制止人们搭乘电梯逃生。由于当其受高温影响,或停电停运,或许火焚烧,必将连累搭乘电梯的人,乃至夺去他们的生命。消防电梯一般都具有有完善的消防功用:它应当是双路电源,即假如修建物作业电梯电源中止时,消防电梯的十分电源能主动迎合,能够持续运转;它应当具有紧迫操控功用,即当楼上发作火灾时,它可承受指令,及时回来首层,而不再持续接收乘客,只可供消防人员运用;它应当在轿厢顶部预留一个紧迫分散出口,假如电梯的开门组织失灵时,也可由此处分散逃生。

  关于高层民用修建的主体部分,楼层面积不超越1500平方米时,应设置一台消防电梯;超越1500平方米,缺乏4500平方米时,应设置两台消防电梯;每层面积超越4500平方米时,应设置三台消防电梯。消防电梯的坚井应当独自设置,不得有其他的电气管道、水管、气管或通风管道经过。消防电梯应当设有前室,前室应设有防火门,使其具有防火防烟功用。消防电梯的载重量不宜小于800公斤,火电梯功用之比较轿厢的平面尺度不宜小于1米×1.5米,一部电梯背面的中瑞友爱史:迅达集,其效果在于能转移较大型的消防用具和放置救生的担架等。消防电梯内的装饰资料,有必要对错燃建材。消防电梯动力与操控电线应采纳防水办法,消防电梯的门口应设有漫坡防水办法。消防电梯轿厢内应设有专用电话,在首层还应设有专用的操作按钮。假如在这些方面功用都能合格,那么假如修建内发作火灾,消防电梯就能够用于消防救生。假如不具有这些条件,一般电梯则不可用于消防救生,着火时搭乘电梯将有生命危险。

  一般电梯不能笔直逃生

  一般电梯不具有消防安全的条件,火灾时不能作为笔直分散东西运用,其主要原因如下:

  1.电源无保证。由于发作火灾时,消防人员有必要堵截一切正常作业电源,启用应急电源。一部电梯背面的中瑞友爱史:迅达集

  2.发作烟囱效应。由于电梯运转中,电梯竖井就失去了防烟效果,而成为拔烟拔火的笔直通道,一般电梯与消防防既滋长焰火分散延伸,一路走来 不忘初心——我国电梯工,又要挟人的生命安全。

  3.分散才能有限。发作火灾时,电梯一次只能载运十几个人,其余人还要等候,这样会延误分散机遇。一组相片记载康力电梯工业园20年开

  4.假如电梯发作机电毛病(或停电),分散人员就会被困在电梯轿箱之内而无法脱险。

  Function Compare of Ordinary Elevator and Fire-Proof Elevator

  
Fire-proof elevator is the elevator used by firemen to control the fire and rescue the people. Therefore, the fire-proof elevator has high requires in fire-fighting.

   The ordinary elevator does not have the fire-proof function, when the fire accidents happen, people should not take the elevator, because the high temperature makes the stopping of elevator. While the fire-proof elevator has perfect fire-fighting function: when the fire happens, the special electric of the elevator will operate auto, which will give the order to control the elevator back to the top floor of building to wait the use of firemen.

   In terms of the high buildings, the areas less than 1500 ㎡ should equip at least 1 fire-proof elevator; while more than 1500 ㎡, and less than 4500 ㎡ should has 2 fire-proof elevators; and more than 4500 ㎡, equipped with 3 fire-proof elevators. The main function of the fire-proof elevator is to carry the fire-fighting equipments, so the area should more than 1 m*1.5m. and the material of elevator should also be the non-fire material.

  
The ordinary elevator can not take in fire accidents

   1. the electricity will be cut in the fire accidents.

   2.the elevator well will be the chimney in the accident which will threaten the life of passengers.

   3. the elevator can only take a dozen of people in one time, which may delay the time.

   4. if the elevator stops due to the cut of electricity, the people will be tight in the room and can not survive.
