The installation and construction technology of FRP wind pipe is the key point of this project. Inorganic glass fiber reinforced plastic wind pipe has been widely used in recent years. With the improvement of manufacturing technology and the application in large-scale engineering, construction workers have been able to master this mature construction technology. In this project, the glass glass steel wind pipe has a large amount of application and high installation requirements, so it is the key and difficult point in the construction of the ventilation and air conditioning system in this project.
The installation of a ventilator (including a smoke exhauster)
1) whole fan installed, carrying and lifting rope shall be bound in the rotor and the shell rings or the bearing cover.
2) the inlet and outlet pipes of fans should have independent support and are firmly connected with foundations or other buildings. When air pipes are connected with fans, they must not be forced to match counterparts, and the crew should not be able to bear the weight of other parts. The outgoing parts of the ventilator transmission and the inlet and outlet of the direct air must be equipped with a protective shield (net) or other safety measures.
3) a centrifugal fan installed on the ground: its foundation should be flat, and by adjusting the position of the damper, the size of the force and deformation of each damper is consistent.
4) installation of suspension type axial flow fan: the fan is equipped with steel plate connecting plate and type steel pick beam, so that the size of each damper is in accordance with the force and deformation size.
