1、 What is air duct and what types of common air ducts are there

風管主要指空調系統的通風管道，它常常被忽視，但卻是空調系統的重要組成部分。風管是由薄鋼板、鋁板、硬聚氯乙烯板、玻璃鋼以及其它復合材料等制成的，用于輸送空氣和空氣混合物的各種管道的總稱。

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、按照材質可分為：

1. It can be divided into:

金屬風管、非金屬風管。其中：

Metal air duct and non-metal air duct. Of which:

（1）金屬風管又可分為：

(1) Metal air ducts can be divided into:

鋼板風管、鋁板風管、不銹鋼風管等；

Steel plate air duct, aluminum plate air duct, stainless steel air duct, etc;

（2）非金屬風管可以分為：

(2) Non metallic air ducts can be divided into:

硬聚氯乙烯風管、有機玻璃風管、無機玻璃風管、玻璃鋼風管以及其它復合材料風管等；

UPVC air ducts, plexiglass air ducts, inorganic glass air ducts, FRP air ducts and other composite air ducts;

2、按照風管外形可分為：

2. According to the shape of the air duct, it can be divided into:

圓形風管、矩形風管；

Circular air duct, rectangular air duct;

3、按照通風空調系統工作壓力可分為：

3. According to the working pressure of ventilation and air conditioning system, it can be divided into:

高壓風管、中壓風管、低壓風管三個類別

High pressure air duct, medium pressure air duct and low pressure air duct

二、主要機具有哪些

2、 What are the main machines

1、機械設備：

1. Mechanical equipment:

剪板機、振動剪板機、電剪、手動折方機、三輥卷圓機、聯合沖剪機、法蘭卷圓機、廂式聯合單平咬口機、手剪、圓彎頭咬口機、壓筋合縫隙兩用機、插條成型機、電動拉鉚槍、電焊機、電動角向磨光機、臺鉆、砂輪切割機、手電鉆、沖孔機、空壓機及油漆噴槍等。

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.

雙面鋁箔絕熱板風管還需下列工具：雌雄刀、圓孔鑿孔刀、月亮刀、電燙斗、手工開槽工具、裝訂搶等。

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、測量檢驗工具：

2. Measurement and inspection tools:

游標卡尺、鋼直尺、鋼卷尺、游標尺、內卡鉗、漏風量測試裝置等。

Vernier caliper, steel ruler, steel tape, traveling scale, inner caliper, air leakage test device, etc.

注：隨著科學技術的發展，施工機具的種類、型號越來越多，施工機具的配備應以工程性質、施工條件及設計圖紙要求合理配置。

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、進人施工現場的設備進行檢查驗收，定期維護保養。

3. Check and accept the equipment entering the construction site and maintain it regularly.

三、風管制作作業條件有何要求

3、 What are the requirements for air duct manufacturing conditions

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、作業地點應有安放施工機具和材料堆放場地，設施和電源應有可靠的安全防護裝置。作業場地道路應暢通。有能滿足消防要求的各種器械及設施；

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、加工設備布置在建筑物內時，應考慮建筑物樓板、梁的承載能力，必要時應采取相應措施；

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、大樣圖、系統圖經審查符合要求，并進行了技術及安全交底；

4. The detailed drawing and system drawing meet the requirements after review, and technical and safety disclosure has been carried out;

5、對于潔凈系統的風管制作應有干凈封閉庫房儲存成品或半成品；

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、加工場地應預留現場材料、成品以及半成品的運輸通道，加工場地的選擇不得阻礙消防通道。

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.
