1、保温钉粘接密度、矩形风管和设备的保温钉应排列均匀,其数量不少于24每平方米,每平方米侧不小于15的底面,每平方米不少于12,和首行从风道保温钉或绝缘材料边缘的距离应小于120MM。在24小时粘钉后,轻轻拉动保温钉,当它不松动脱落时,就可以铺设绝缘材料了。
1. The bonding density of insulation nails, the insulation nails of rectangular air duct and equipment shall be evenly arranged, the number of which shall not be less than 24 per square meter, the bottom surface of which shall not be less than 15 per square meter, the distance between each square meter and the first line from the edge of insulation nails or insulation materials of air duct shall not be less than 120mm. After sticking nails for 24 hours, gently pull the insulation nails. When it does not loose and fall off, the insulation material can be laid.
2、风管与设备的连接,易于生产的冷凝液的位置,须绝缘良好,紧密和无缝。
2. The connection between the air duct and the equipment and the position of condensate easy to produce must be well insulated, tight and seamless.
3、保温材料的材料、规格和耐火性能须符合设计和防火要求,须检验材料合格证。
3. The material, specification and fire resistance performance of thermal insulation materials shall meet the design and fire protection requirements, and the material certificate shall be inspected.
4、风阀在保温后不会妨碍操作,启闭标记清晰清晰。
4. The air valve will not hinder the operation after heat preservation, and the opening and closing marks are clear.
5、空气管道做绝缘漏泄试验,低风系统每10米以内接缝漏水2点,而100米缝平均不到8合格。
5. The insulation leakage test of the air pipeline shows that there are 2 points of leakage in the joints of the low air system within 10 meters, and the average leakage in the joints of 100 meters is less than 8 points.
6、玻璃毡毡应紧密地附着在风管表面,紧固和放松。不锈钢螺旋风管玻璃布保护层应适中,搭接宽度均匀,平整美观。
6. The glass felt shall be tightly attached to the surface of the air duct, and shall be tightened and loosened. The glass cloth protective layer of stainless steel spiral duct should be moderate, the overlapping width should be uniform, flat and beautiful.
保温:保温钉粘贴60mm长的铝制保温钉,保温钉粘接应排除在粘接前钢板表面的油污和灰尘,使用前应确保粘接可靠性实验胶;将保温钉粘接000表面用胶水粘接,坚持一分钟干微粘上后。
Heat preservation: the heat preservation nail shall be pasted with 60mm long aluminum heat preservation nail. The oil stain and dust on the steel plate surface before bonding shall be eliminated, and the bonding reliability test glue shall be ensured before use; Glue the heat preservation nail to the surface for one minute.
切切:当风管处于材料下时,应按施工图所要求的尺寸加工。为了配合法兰,避免空气管与法兰之间的尺寸误差,很难安装空气管和法兰。管子的尺寸是根据外径或外径而定的,厚度是根据规格和设计要求而定的。
Cutting: when the air duct is under the material, it should be processed according to the size required by the construction drawing. In order to fit the flange and avoid the dimensional error between the air pipe and flange, it is difficult to install the air pipe and flange. The size of the pipe is determined according to the outer diameter or outer diameter, and the thickness is determined according to the specification and design requirements.
空气管保温:接口用铝箔胶带密封,接口上的油污和灰尘在密封前应清洗干净,以免发生故障。胶带受力均匀、适中,带牢固地粘在铝箔玻璃棉毡的表面,无开裂和脱落。
Air pipe insulation: the interface is sealed with aluminum foil tape, and the oil and dust on the interface should be cleaned before sealing to avoid failure. The stress of the tape is even and moderate, and the tape is firmly adhered to the surface of the aluminum foil glass wool felt without cracking and falling off.
咬口:镀锌钢管采用风钉扣、按扣,侧板和上下板在咬后相互咬边。
Undercut: galvanized steel pipe adopts wind nailing and snap fastener, and side plate and upper and lower plate undercut each other after undercutting.
