卷簾門作為各大商鋪車庫必不可少的門的類型,深受大家的喜愛。防火卷簾門因其獨特的功能,在它的崗位上充分發(fā)揮著它的作用,其中更重要的零件部分就是卷簾機,防火卷簾門卷簾機有著一定的要求。接下來就讓我們一同來看一下防火卷簾門的卷簾機有哪些要求以及防火卷簾門的耐火等級。
As an essential type of door for the major shops, shopping malls and garages, rolling shutter doors are deeply loved by everyone. Because of its unique function, fire shutter door plays an important role in its post. The most important part is rolling shutter machine, which has certain requirements. Next, let's take a look at the requirements of the rolling machine of the fire shutter door and the fire resistance rating of the fire shutter door.
一、防火卷簾門的卷門機要求:
1、 Requirements for rolling machine of fireproof rolling shutter door:
(一)外觀及零部件
(1) Appearance and parts
1、卷門機的外殼應(yīng)完整,無缺角和明顯裂紋、變形。
1. The shell of the door rolling machine shall be complete without missing angle, obvious crack and deformation.
2、涂覆部位表面應(yīng)光滑,無明顯氣泡、皺紋、斑點、流掛等缺陷。
2. The surface of coating part shall be smooth without obvious bubble, wrinkle, spot, sagging and other defects.
3、卷門機的零部件不應(yīng)使用易燃和可燃材料制作。
3. The components of the door rolling machine shall not be made of inflammable and combustible materials.
4、卷門機的操控設(shè)備應(yīng)有利于使用工作人員操控。
4. The control equipment of the door rolling machine should be convenient for the operating staff.
(二)基本性能
(2) Basic performance
1、卷門機的額定輸出扭矩應(yīng)符合設(shè)計要求。生產(chǎn)方應(yīng)提供檢驗合格證明。
1. The rated output torque of the door rolling machine shall meet the design requirements. The manufacturer shall provide the inspection certificate.
2、卷門機剎車抱閘應(yīng)可靠,剎車力不可小于額定值輸出扭矩下配重后的1.5倍,滑行位移不可超過20mm。
2. The brake of the door rolling machine shall be safe and reliable. The braking force shall not be less than 1.5 times of the counterweight under the rated output torque, and the sliding displacement shall not exceed 20 mm.
3、 卷門機應(yīng)具備手動式使用裝置,應(yīng)靈便、可靠,安裝位置應(yīng)有利于操作。使用手動式操作設(shè)備操縱防火卷簾門啟、閉運行時,嚴禁出現(xiàn)滑行碰撞現(xiàn)象。
3. The door rolling machine shall be equipped with manual operation device, which shall be convenient and reliable, and the installation position shall be convenient for operation. When using manual operation equipment to operate the fire shutter door to open and close, sliding collision is strictly prohibited.
4、卷門機應(yīng)具備電動式啟閉和借助防火卷簾門總重量恒定下滑的功能性,電動式啟閉和自重下滑速度應(yīng)符合6.4.5的要求,啟動防火卷簾門自重下降的臂力不應(yīng)大于70N。
4. The rolling door machine shall have the function of electric opening and closing and constant sliding of the total weight of the fireproof rolling shutter door. The speed of electric opening and closing and self weight sliding shall meet the requirements of 6.4.5, and the arm force for starting the self weight decline of fire shutter door shall not be greater than 70N.
5、卷門機應(yīng)具有全自動限位裝置,當(dāng)防火卷簾門啟、閉上、下限位時,能全自動終止,其多次重復(fù)精準定位誤差應(yīng)低于20mm。
5. The door rolling machine shall be equipped with automatic limit device, which can automatically terminate when the fire shutter door is opened and closed to the upper and lower limits, and its repeated accurate positioning error shall be less than 20 mm.
二、防火卷簾門的耐火等級
2、 Fire resistance rating of fireproof rolling shutter door
防火卷簾防火性能的分級尚無標準,根據(jù)卷簾門的防火級別大體可分為:特級、、乙級、丙級四種,各級別耐火時間各不相同,目前我國執(zhí)行的標準:特級防火卷簾門的耐火時間不小于3小時,耐火防火時間不小于1.5小時,乙級不低于1小時,丙級不低于0.5小時,根據(jù)其安裝環(huán)境的重要性來確定安裝什么級別的防火卷簾。
There is no national standard for the classification of fire performance of fire shutter. According to the fire rating of rolling shutter door, it can be roughly divided into four categories: super class, class A, grade B and grade C. The fire resistance time of each level is different. At present, the standard implemented in China is that the fire resistance time of super grade fire shutter door is not less than 3 hours, that of Grade A is not less than 1.5 hours, that of grade B is not less than 1 hour, and that of grade C is not low 5 hours, according to the importance of the installation environment to determine what level of fire shutter installation.
