1、 What is air duct and what types of common air ducts are there
Air duct mainly refers to the ventilation duct of central air conditioning system, which is often ignored, but it is an important part of the air conditioning system. Air duct is a general term for all kinds of pipes used to transport air and air mixture, which are made of thin steel plate, aluminum plate, rigid polyvinyl chloride plate, glass fiber reinforced plastic and other composite materials.
1. It can be divided into:
Metal air duct and non-metal air duct. Of which:
(1) Metal air ducts can be divided into:
Steel plate air duct, aluminum plate air duct, stainless steel air duct, etc;
(2) Non metallic air ducts can be divided into:
UPVC air ducts, plexiglass air ducts, inorganic glass air ducts, FRP air ducts and other composite air ducts;
2. According to the shape of the air duct, it can be divided into:
Circular air duct, rectangular air duct;
3. According to the working pressure of ventilation and air conditioning system, it can be divided into:
High pressure air duct, medium pressure air duct and low pressure air duct
2、 What are the main machines
1. Mechanical equipment:
Plate shears, vibrating plate shears, electric shears, manual Square folding machines, three roll rounding machines, combined punching shears, flange rounding machines, van type combined single flat seaming machines, hand shears, round elbow seaming machines, double-purpose machines for pressing ribs and gaps, cutting machines, electric riveting guns, electric welding machines, electric angle grinders, bench drills, grinding wheel cutting machines, electric drills, punching machines, air compressors, paint spray guns, etc.
The air duct of double-sided aluminum foil insulation board also needs the following tools: male and female knives, round hole drilling knives, moon knives, electric irons, manual slotting tools, binding grab, etc.
2. Measurement and inspection tools:
Vernier caliper, steel ruler, steel tape, traveling scale, inner caliper, air leakage test device, etc.
Note: with the development of science and technology, there are more and more types and models of construction machines and tools. The allocation of construction machines and tools should be reasonably configured according to the engineering nature, construction conditions and design drawings.
3. Check and accept the equipment entering the construction site and maintain it regularly.
3、 What are the requirements for air duct manufacturing conditions
1. Air duct prefabrication should have an independent work site, which should be flat and clean, and the processing platform should be leveled. The site of double-sided aluminum foil insulation board air duct and other composite air ducts should be dry, and there should be enough finished products stacking site;
2. The working place shall have a stacking place for construction machines and materials, and the facilities and power supply shall have reliable safety protection devices. The roads on the operation site should be unblocked. There are various devices and facilities that can meet the fire protection requirements;
3. When the processing equipment is arranged in the building, the bearing capacity of the building floor and beam should be considered, and corresponding measures should be taken when necessary;
4. The detailed drawing and system drawing meet the requirements after review, and technical and safety disclosure has been carried out;
5. For the air duct production of the clean system, there should be a clean closed warehouse to store finished products or semi-finished products;
6. The processing site shall reserve transportation channels for on-site materials, finished products and semi-finished products, and the selection of processing site shall not hinder the fire access.
