What should we pay attention to when installing Weihai ventilation duct?

  Ventilation duct is a municipal infrastructure to circulate air and reduce the concentration of harmful gases
The fabrication and installation of Weihai ventilation pipe shall comply with the provisions of the current national standards for design and related products, and the factory inspection certificate shall be applied
The materials shall be accepted according to the current national standards when entering the site
So what should we pay attention to when installing Weihai ventilation duct 1
When the air duct is connected with the fan, a soft joint shall be added at the air inlet and outlet, and the section size of the soft joint shall be consistent with the air inlet and outlet of the fan
Generally, the hose joint can be made of canvas, artificial leather and other materials
The hose length should not be less than 200, and the tightness should be appropriate
The flexible hose can buffer the vibration of the fan 2
Before the air duct is connected with dust removal equipment and heating equipment, it shall be prefabricated and installed according to the actual mapping drawings after the equipment installation 3
When installing the air duct, the air inlet and outlet should be opened during the prefabrication of the air duct
If it is necessary to open an air outlet on the installed air duct, the interface should be tight 4
When transporting gas with condensate or high moisture content, its horizontal pipeline should be provided with slope and connected with drainage pipe at the low point
During installation, longitudinal joints should not appear at the bottom of the air duct, and the joints at the bottom should be sealed 5
For the steel plate air duct conveying flammable and explosive gases, jumper wires shall be installed at the connecting flange of the air duct and connected with the electrostatic grounding grid Please strictly follow the above installation precautions
Here are the precautions for the installation of Weihai ventilation duct The news comes from the website http://www
