关于防火卷帘门部件的三大常见问题

来源:http://www.jnzxmy.com 日期:2022-10-15 发布人:
买一个好的卷帘门很重要,但是后期卷帘门的使用也同样的重要,不当的操作会使卷帘门受到损坏。下面济南卷帘门厂家来讲讲关于防火卷帘门部件的三大常见问题。
It is important to buy a good roller shutter door, but the use of roller shutter door in the later stage is also important. Improper operation will damage the roller shutter door. Next, Jinan roller shutter door manufacturer will talk about three common problems about fire shutter door components.
防火卷帘门帘体厚度问题:门帘厚度问题门帘厚度即帘板所用钢板的厚度,目前普遍存在着偷工减料现象,有些厂家送交测试时采用较厚钢板的帘板,取得合格证后,则改用较薄的进行生产。由于在安装现场卷帘门的帘板厚度不易测量,容易蒙混过关,因此,有很多防火卷帘门因门帘厚度都未达到要求,降低使用寿命与耐火时限。钢质特技防火卷帘门
The thickness of the fire resisting roller shutter: the thickness of the shutter is the thickness of the steel plate used for the shutter. At present, there is a widespread phenomenon of jerry built. Some manufacturers use thicker steel plates for testing. After obtaining the certificate, they use thinner ones for production. Because the thickness of the shutter of the rolling shutter door is not easy to measure at the installation site, it is easy to muddle through. Therefore, many fireproof rolling shutter doors have lower service life and fire resistance time limit because the thickness of the shutter does not meet the requirements.

防火卷帘门门楣结构问题:门楣结构问题按标准防火卷帘门须设置门楣结构,而目前普遍使用的是没有门楣的防火卷帘门,这种门发生火灾时阻止不了火势向上形成的强大冲击.导致烟气通过门楣向外蔓延。门楣处的密封性是防火、防烟的关键所在,若安装没有门楣结构的防火卷帘门,则不能起到防火阻隔的作用,形同虚设。
The lintel structure of the fire rolling shutter door: the lintel structure of the fire rolling shutter door shall be set according to the national standard. At present, the fire rolling shutter door without lintel is widely used, which can not prevent the strong impact of the fire when a fire occurs, causing smoke to spread outward through the lintel. The sealing at the lintel is the key to fire and smoke prevention. If a fire rolling shutter door without lintel structure is installed, it cannot play the role of fire prevention and separation, and it is just a figment.
防火卷帘门传动装置强度问题:防火卷帘轴的传动装置强度也是卷帘门的一个重要参数,目前这种强度不合格的产品很多,严重影响了防火卷帘门的使用。卷帘轴的结构主要指卷帘轴两端轴头塞人钢管内的深度及其结构。轴头塞人深度应为轴长的1/10左右,且要有两个法兰和足够的焊缝。有些厂商的产品却塞入很短,甚用一个法兰,这种偷工减料的门使用一段时间后有断裂的危险。
The strength of the transmission device of the fire shutter door: The strength of the transmission device of the fire shutter shaft is also an important parameter of the fire shutter door. At present, there are many products with unqualified strength, which seriously affects the use of the fire shutter door. The structure of the roller shutter shaft mainly refers to the depth and structure of the shaft heads at both ends of the roller shutter shaft plugged into the steel pipe. The insertion depth of shaft head shall be about 1/10 of the shaft length, and there shall be two flanges and enough welds. Some manufacturers' products are stuffed very short, even with a flange. This kind of jerry built door may break after being used for a period of time.
此外要注意,断电时手动快速关闭装置的传动问题火灾中。如发生电源中断,现场人员可采用手动速放装置.将门关闭。现在有一部分防火卷帘门没装这种装置。即使装了,也往往因质量问题,不起作用,所以在选择卷帘门时要多考虑购买,更多相关事项就来我们网站http://www.jnzxmy.com咨询吧!
In addition, it should be noted that when the power is cut off, the transmission of the manual quick closing device is in fire. In case of power interruption, on-site personnel can use manual quick release device to close the door. At present, some fire rolling shutter doors are not equipped with such devices. Even if it is installed, it often does not work because of quality problems, so you should consider purchasing more when choosing roller shutter doors, and more relevant matters will come to our website http://www.jnzxmy.com Consult!
