Shenyang ventilation pipeline When installing, the pressure drop is relatively low. As we all know, some ventilation methods should be given priority as technical measures to ensure the air quality of the working and living environment and prevent indoor environmental pollution. Next, spiral Ventilation duct With the seaming forming process, the mold used for its imported equipment is also a special steel structure. Even if it has been used for three or five years, the surface of its pressing mold will remain unchanged.
Before the connection between Shenyang ventilation duct and dust removal equipment, heating equipment, etc., the prefabrication and installation shall be stopped according to the theoretical mapping drawings after the end of the equipment installation. When installing ventilation ducts, holes should be opened during the prefabrication of air ducts on air inlet and air outlet days. If it is necessary to open an air outlet on the air duct at the end of the unit, the interface should be tight. The hose connector can generally be made of canvas, artificial leather and other materials. The length of the hose should not be less than 200. The tightness should be appropriate. The flexible hose can buffer the vibration of the fan.
When transporting gas with condensed water or high moisture content, its horizontal pipeline should be set with slope and connected with drain pipe at the low point. When installing, the bottom of the air duct should not show longitudinal joints, and the sealing treatment should be stopped at the joints at the bottom. For steel plate air ducts transporting flammable and explosive gases, jumper wires shall be installed at the connecting flanges of Shenyang ventilation ducts and connected with the electrostatic grounding grid. When the height of the horizontal air duct is more than 4m, the installation personnel shall wear safety belts. The springboard on the scaffold or mobile support shall be fixed well, and the width of the springboard shall conform to the safety specifications. The installation personnel on the scaffold shall carry bags to prevent objects or electric drills from falling and injuring people. When the galvanized welded air duct is connected with the fan, a soft joint shall be added at the air inlet and outlet, and the section dimension of the soft joint shall be the same as the air inlet and outlet of the fan.
