Installation of Dongguan Spiral Duct
排风和通风系统的安装技术水平不断提高,也有很一些用户比较关心它是怎样安装,才能使排风和通风系统的效果更好.现在由东莞宇晨的小编与大家一起来了解螺旋风管的安装 ： With the development level of the national economy , the installation and technical level of exhaust and ventilation systems has been continuously improved , and there are also some users who are more concerned about how it is installed in order to make the exhaust and ventilation system work better . Let us know the installation of spiral duct :
1. The general air supply and exhaust system and ventilation system should be installed according to the installation design actually designed on the site, and the construction of the building envelope must be completed. At the same time, the obstacles at the installation site must be cleared and the ground free of debris.
2. Determine the level, install the air pipe support and hanger, and brush the anti-rust paint after removing the rust. The hoisting points of air pipe support and hanger are usually embedded iron, secondary grouting of support and hanger, expansion bolt method or nail.
3. According to the center line of the duct , find the laying position of the boom. The single boom is on the center line of the duct. The double boom can be installed symmetrically according to the bolt hole spacing of the tray or the center line of the duct. The suspender can be welded to the suspender according to the form of the suspender, or it can be hung on the suspender. After welding, anti-rust paint should be applied.
4. When installing the riser pipe card, first fix the top pipe, and then hang the wire at the center with a wire hammer. The lower pipe card can be fixed by wire. When the air duct is long and a row of brackets need to be installed, the two ends can be installed first, and then with the brackets at both ends as the standard, the level of the middle bracket can be found by the cable method for installation.
5. In order to ensure the tightness of the flange interface, there should be gaskets between the flanges. Generally, the flange gaskets for air conditioning systems and air supply and exhaust systems use 8501 sealing tape, and soft rubber plates with closed-cell sponge rubber plates. Flange gaskets must not be squeezed or protruded into the tube. Flange gaskets should be minimized with joints. The joints should be trapezoidal or tenon-shaped and glued tightly. It is strictly forbidden to plug gaskets into flange gaps after flange connection.
6. For flange connection, align the two flanges first, put on a few bolts and load the nuts, do not tighten them for the time being, and then use a sharp punch to plug into the screw holes that cannot be bolted, and place the two screws The holes are straight until all bolts are put on, then tighten the bolts. In order to prevent the bolts from slipping, tighten the bolts gradually and evenly according to the cross. The nuts of the connecting flanges should be on the same side. The picture of the installed ventilation duct should be based on the flanges at both ends. Wiring inspection Should be straight.
