镀锌风管加工应注意的几大问题
Several problems needing attention in the processing of galvanized air duct
1、当镀锌风管采用地面预组装后架空安装时，限制预组装的长度是为了遮免镀锌风管因自重产生的弯曲而破坏构件接口。井盖钢模具 U型槽模具 天津水处理设备 检查井钢模具 保定公司注册 u型槽模具 流水槽模具
1. When the galvanized air duct is installed overhead after ground pre assembly, the length of pre assembly is limited to prevent the bending of galvanized air duct due to its own weight from damaging the component interface.
2、竖井内通镀锌风管道垂直安装，由于空间少，又不便于以后检修，故镀锌风管一般采用外套角钢法兰连接以增加连接点的牢固程度和强度，并把法兰作成“井”形，吊筋直接吊在角钢法兰的吊耳上而不另设支撑件。
2. The galvanized air duct in the shaft is installed vertically. Due to less space and inconvenient for future maintenance, the galvanized air duct is generally connected with an outer angle steel flange to increase the firmness and strength of the connection point, and the flange is made into a "well" shape. The hanging reinforcement is directly hung on the lifting lug of the angle steel flange without additional support.
3、非法兰连接的玻璃纤维复合板镀锌风管垂直安装的支撑件制作与安装的方法。
3. The invention relates to a method for manufacturing and installing a support for vertical installation of a non flange connected glass fiber composite plate galvanized air duct.
4、通镀锌风管道在运输过程应有防止损伤镀锌风管的保护措施。
4. The galvanized air duct shall be provided with protective measures to prevent damage to the galvanized air duct during transportation.
