山東通風管道首要用于聯(lián)通兩地之間的空氣流通，起到通風透氣的效果?，F(xiàn)在市面上運用廣泛的就是螺旋風管。螺旋風管市場上按材質(zhì)一般分為三類：鍍鋅螺旋風管、不銹鋼螺旋風管、復合螺旋風管。其中，不銹鋼風管質(zhì)量好，適用性強，但高。

Shandong ventilation pipeline is mainly used to connect the air flow between the two places, playing a ventilating and ventilating effect. Now the spiral duct is widely used in the market. The spiral duct market is generally divided into three categories according to the material: galvanized spiral duct, stainless steel spiral duct and composite spiral duct. Among them, stainless steel air duct has good quality and applicability, but its price is high.

現(xiàn)在市場通廣的螺旋風管是鍍鋅板。鍍鋅板螺旋風管的特性根本和不銹鋼螺旋風管的相同，可是與不銹鋼風管低三分之二甚更低。復合螺旋風管一般應(yīng)用在外界環(huán)境較為普通，對風管要求不太高的場所。

Now the spiral air duct widely circulated in the market is galvanized sheet. Galvanized sheet spiral duct has the same characteristics as stainless steel spiral duct, but the price is two-thirds lower than stainless steel duct or even lower. Compound spiral ducts are generally used in places where the external environment is relatively common and the requirements for ducts are not very high.

因為鐵皮簡單在各種環(huán)境下發(fā)生化學反響，形成腐蝕、生銹，而鋅在枯燥的空氣中幾乎不發(fā)生變化。在濕潤的空氣中，鋅外表會生成致密的堿式碳酸鋅膜。螺旋風管首要是在風管鐵皮上鍍上一層鋅，對鐵皮起到維護的效果。鋅鍍層經(jīng)鈍化處理、染色或涂覆護光劑后，能顯著提高其防護性和裝飾性通風管道

Because iron sheet reacts chemically in various environments, forming corrosion and rust, while zinc hardly changes in dry air. In wet air, the appearance of zinc produces a dense alkaline zinc carbonate film. The main purpose of spiral air duct is to coat the iron sheet with zinc, which can maintain the iron sheet. After passivation, dyeing or coating with light protector, zinc coating can significantly improve its protective and decorative ventilation ducts.

螺旋風管對我們通風和空氣轉(zhuǎn)化都起著一個十分重要的效果，尤其是在通風設(shè)備中，有用的把通風設(shè)備的各個部位都連接一起，讓通風設(shè)備愈加順暢的運轉(zhuǎn).的螺旋風管 在規(guī)劃的時分就要本著讓企業(yè)在運用時分能達到確保運用效果，并且還盡量起到省錢，省維護費，添加產(chǎn)品附加值的效果、螺旋風管要達到這樣的效果，較少產(chǎn)品要做到以下 幾點根本要求。螺旋風管

Spiral duct plays a very important role in our ventilation and air conversion. Especially in ventilation equipment, it is useful to connect all parts of the ventilation equipment to make the ventilation equipment run smoothly. Protecting fees, adding value-added effect of products, spiral ducts to achieve such effect, at least products to achieve the following basic requirements. Spiral duct

一：把握通風管道內(nèi)流動阻力 (摩擦阻力和部分阻力)的核算辦法和壓力散布規(guī)律；

Firstly, the calculation method of flow resistance (frictional resistance and partial resistance) and the law of pressure distribution in ventilation ducts should be grasped.

第二：熟練把握比摩阻、典型部分構(gòu)件的部分阻力系數(shù)的斷定辦法；

Secondly, the method of determining specific friction and partial resistance coefficient of typical components should be mastered skillfully.

第三：把握均勻送風管道規(guī)劃核算的原理和辦法；

Third: grasp the principle and method of planning and accounting of uniform air supply pipeline;

第四：把握風管的布置和挑選；

Fourth: grasp the layout and selection of air ducts;

第五：了解氣力輸送體系的管道核算和氣一固兩相流的阻力特性；

Fifth: Understand the pipeline accounting of pneumatic conveying system and the resistance characteristics of gas-solid two-phase flow.

第六：能斷定風管體系中風機的作業(yè)點。

Sixth: It can determine the operation point of the fan in the duct system.
