Helical ducts play a crucial role in our ventilation and air exchange, especially in ventilation equipment, effectively connecting all parts for smoother operation. During the design phase, it is essential to ensure that the enterprise achieves the desired performance while also aiming to save costs, reduce maintenance expenses, and increase product value. To achieve such effects, the products must meet the following basic requirements.
1: Master the calculation methods for the flow resistance within ventilation ducts (frictional resistance and local resistance) and the pressure distribution patterns.
2: Proficient in mastering the methods for determining the local resistance coefficient of friction and typical local components.
3. Master the principles and methods of uniform air distribution duct design calculations.
4: Master the layout and selection of ductwork.
Understanding the pipeline calculation of the pneumatic conveying system and the resistance characteristics of gas-solid two-phase flow.
We can accurately determine the working point of the fan in the duct system.
Primary Use:
Ventilation System: Delivers fresh air and exhausts harmful gases to the outdoors, while bringing fresh outdoor air indoors. Due to the high flow rates of the ventilation system, it requires air transmission pipes with low resistance to save on construction and operating costs. Spiral ducts produced by spiral duct machines are suitable. The raw material is galvanized steel strip, and stainless steel material can also be used for corrosive and especially humid environments.
The air conditioning system: Central air conditioning, cold storage, etc., can use spiral ducts for internal insulation materials, which are aesthetically pleasing.
Three: Exhaust Gas System: Kitchens in canteens, restaurants, and hotels generate a large amount of smoke, which requires effective exhaust. Spiral ducts are an appropriate solution, replacing traditional manual methods. Spiral ducts offer good strength and are both economical and practical.
Four: Dust Removal and Bulk Material Conveying System: For flour mills, flower arrangement factories, feed mills, etc., the collection and conveying of dust removal equipment. In pneumatic conveying systems, finer and more loose material particles can be transported using spiral air ducts, offering low cost and effective results.
