山东通风管道三分PK拾首要用于联通两地之间的空气流通,起到通风透气的效果。现在市面上运用广泛的就是螺旋风管。螺旋风管市场上按材质一般分为三类:镀锌螺旋风管、不锈钢螺旋风管、复合螺旋风管。其中,不锈钢风管质量好,适用性强,但价格高。

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.

现在市场上流通广的螺旋风管是镀锌板。镀锌板螺旋风管的特性根本和不锈钢螺旋风管的相同,可是价格与不锈钢风管低三分之二甚至更低。复合螺旋风管一般应用在外界环境较为普通,对风管要求不太高的场所。

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。

因为铁皮简单在各种环境下发生化学反响,形成腐蚀、生锈,而锌在枯燥的空气中几乎不发生变化。在湿润的空气中,锌外表会生成致密的碱式碳酸锌膜。螺旋风管首要是在风管铁皮上镀上一层锌,对铁皮起到维护的效果。锌镀层经钝化处理、染色或涂覆护光剂后,能显著提高其防护性和装饰性通风管道

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.

螺旋风管对我们通风和空气转化都起着一个十分重要的效果,尤其是在通风设备中,有用的把通风设备的各个部位都连接一起,让通风设备愈加顺畅的运转.优秀的螺旋风管 在规划的时分就要本着让企业在运用时分能达到确保运用效果,并且还尽量起到省钱,省维护费,添加产品附加值的效果、螺旋风管要达到这样的效果,最少产品要做到以下 几点根本要求。螺旋风管

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

第一:把握通风管道内流动阻力 (摩擦阻力和部分阻力)的核算办法和压力散布规律;

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:熟练把握比摩阻、典型部分构件的部分阻力系数的断定办法;

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

第三:把握均匀送风管道规划核算的原理和办法;

三分PK拾Third: grasp the principle and method of planning and accounting of uniform air supply pipeline;

第四:把握风管的布置和挑选;

Fourth: grasp the layout and selection of air ducts;

第五:了解气力输送体系的管道核算和气一固两相流的阻力特性;

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

第六:能断定风管体系中风机的作业点。

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