山東通風(fēng)管道首要用于聯(lián)通兩地之間的空氣流通，起到通風(fēng)透氣的效果?，F(xiàn)在市面上運(yùn)用廣泛的就是螺旋風(fēng)管。螺旋風(fēng)管市場(chǎng)上按材質(zhì)一般分為三類(lèi)：鍍鋅螺旋風(fēng)管、不銹鋼螺旋風(fēng)管、復(fù)合螺旋風(fēng)管。其中，不銹鋼風(fēng)管質(zhì)量好，適用性強(qiáng)，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(chǎng)通廣的螺旋風(fēng)管是鍍鋅板。鍍鋅板螺旋風(fēng)管的特性根本和不銹鋼螺旋風(fēng)管的相同，可是與不銹鋼風(fēng)管低三分之二甚更低。復(fù)合螺旋風(fēng)管一般應(yīng)用在外界環(huán)境較為普通，對(duì)風(fēng)管要求不太高的場(chǎng)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?yàn)殍F皮簡(jiǎn)單在各種環(huán)境下發(fā)生化學(xué)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(rùn)的空氣中，鋅外表會(huì)生成致密的堿式碳酸鋅膜。螺旋風(fēng)管首要是在風(fēng)管鐵皮上鍍上一層鋅，對(duì)鐵皮起到維護(hù)的效果。鋅鍍層經(jīng)鈍化處理、染色或涂覆護(hù)光劑后，能顯著提高其防護(hù)性和裝飾性通風(fēng)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(fēng)管對(duì)我們通風(fēng)和空氣轉(zhuǎn)化都起著一個(gè)十分重要的效果，尤其是在通風(fēng)設(shè)備中，有用的把通風(fēng)設(shè)備的各個(gè)部位都連接一起，讓通風(fēng)設(shè)備愈加順暢的運(yùn)轉(zhuǎn).的螺旋風(fēng)管 在規(guī)劃的時(shí)分就要本著讓企業(yè)在運(yùn)用時(shí)分能達(dá)到確保運(yùn)用效果，并且還盡量起到省錢(qián)，省維護(hù)費(fèi)，添加產(chǎn)品附加值的效果、螺旋風(fēng)管要達(dá)到這樣的效果，較少產(chǎn)品要做到以下 幾點(diǎn)根本要求。螺旋風(fēng)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(fēng)管道內(nèi)流動(dòng)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(fēng)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(fēng)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(fēng)管體系中風(fēng)機(jī)的作業(yè)點(diǎn)。

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