1. Specifications and thickness of ventilation ducts
1. Specifications
Ventilation ducts do not have clearly specified size specifications and are mainly customized based on factors such as the size of the user's room.
2. Thickness
The thickness of the ventilation pipe is closely related to factors such as material, pressure, side length, etc. For rectangular steel sheet air ducts with side lengths less than 32 cm, the thickness of the low and medium pressure steel sheet air ducts is 0.5 mm and the duct thickness high pressure air pressure is 0.75mm, etc. The side length of stainless steel air duct is 10-50cm, the thickness of positive pressure is 0.5mm, the thickness of high pressure is 0.75mm, etc. The aluminum plate air duct has a side length of 10 to 32 cm and a thickness of at moins 1 mm, etc.
2. Precautions for installing ventilation ducts
1 When the air duct and the fan are connected, first add a soft gasket to the air inlet and outlet, as well as its crosspiece. the size of the section should be consistent with the fan inlet and outlet. Pipe joints can be made of materials such as canvas and artificial leather. The length of the pipe should be more than 200 and the sealing should be appropriate. The flexible pipe can dampen the vibration of the fan.
2. Before connecting air ducts, dust collection equipment and heating equipment, and after installing the equipment, the actual drawings should be measured for prefabrication and installation.
3. Before installing the air duct, holes must be made during the prefabrication of the air duct at the air inlet and outlet days. After installation,the air duct should now have air openings and be tightly connected.
4. When transporting gas with high moisture content, the horizontal pipeline should be inclined and the low point should be connected to a drainage pipe. Note that there should be no longitudinal joints at the bottom of the air duct during installation and all joints must be sealed.
5. When transporting flammable steel sheet air ducts, bonding cables should be installed at the air duct connections and connected to the electrostatic grounding grid.
6. When the height of the horizontal air duct is more than 4m, please note that the installer must fasten the seat belt first. Scaffolding springboards must be fixed and the width must comply with safety regulations to prevent tools and other objects from falling and injuring people.
Oyes.
Connection shapes include round, square, conical, etc. The adjustable canvas soft seal is compressible and can be used vertically. It has the advantages of shock absorption, noise reduction and light weight.
Canvas flexible joints are most often used in supply and exhaust air ducts, and are mainly used to connect supply and exhaust air units and the air ducts.
