Jinan ventilation pipe processing is an important part of ventilation and air conditioning system, most of which are made of pipe processing equipment. However, due to a variety of reasons, may lead to pipe processing equipment from the ventilation pipe problems.

①表現(xiàn)：板材外表不平整，厚度不均勻，有顯著的壓痕、裂紋、砂眼和銹蝕等情況;通風(fēng)管道平面下沉，旁邊面向外凸起，有顯著的變形。

① Performance: the surface of the plate is not smooth, the thickness is not uniform, there are significant indentation, cracks, sand holes and corrosion; the plane of the ventilation pipe is sinking, and the side is facing outward, there is significant deformation.

②影響：工作時(shí)通風(fēng)管道漏風(fēng)，空調(diào)負(fù)荷添加，同時(shí)風(fēng)壽命和性能被影響。

② Impact: air leakage in ventilation duct, air conditioning load increase, and air life and performance are affected.

③原因：資料不合格，不能滿(mǎn)意制造通風(fēng)管道的需求。

③ Cause: the data is not qualified, and the requirement of manufacturing ventilation duct is not satisfied.

④辦法：在使用通風(fēng)管道加工設(shè)備制造通風(fēng)管道前，要先查看資料出廠(chǎng)合格證書(shū)和資料質(zhì)量證明還有外觀厚度等，確保資料是可用的。

④ Methods: before using the ventilation pipe processing equipment to manufacture the ventilation pipe, check the factory certificate, quality certificate and appearance thickness of the materials to ensure that the materials are available.

在應(yīng)用前人們應(yīng)當(dāng)按時(shí)除去排煙風(fēng)機(jī)里邊的塵士，特別是離心葉輪上的塵士、誤點(diǎn)等殘?jiān)?，以預(yù)妨生銹和失調(diào)。另一個(gè)還要盡量減少機(jī)器設(shè)備將會(huì)出現(xiàn)的一些常見(jiàn)故障，比如電級(jí)電流量很大或是溫度太高，滾動(dòng)軸承箱猛烈超越這些，搞好預(yù)防工作中。

Before the application, people should remove the dust in the exhaust fan on time, especially the dust on the centrifugal impeller, and the residue of delay, so as to prevent rust and maladjustment. On the other hand, we should try our best to reduce some common faults of machinery and equipment, such as large electric current or too high temperature, rolling bearing box violently surpassing these, and do a good job in the prevention work.

通風(fēng)管道展開(kāi)步驟基本上可以分為熟悉圖形，形體分析，求直線(xiàn)的實(shí)長(zhǎng)或平面的實(shí)形，確定展開(kāi)方法和畫(huà)展開(kāi)圖這幾個(gè)部分。在進(jìn)行展開(kāi)下料前，要熟悉施工圖紙，這是一項(xiàng)準(zhǔn)備工作，主要是對(duì)將要展開(kāi)的關(guān)鍵和部件有所了解，如管道在圖紙上的尺寸大小、制作材料等。

The unfolding steps of ventilation duct can be basically divided into familiar graphics, shape analysis, finding the real length of straight line or the real shape of plane, determining the unfolding method and drawing the unfolding drawing. Before unfolding and blanking, first of all, be familiar with the construction drawings, which is a preparatory work, mainly to understand the key and components to be unfolded, such as the size of the pipeline on the drawings, manufacturing materials, etc.

而對(duì)于比較復(fù)雜的管件，則需要對(duì)施工圖紙進(jìn)行反復(fù)閱讀和分析，針對(duì)有關(guān)問(wèn)題要及時(shí)提出和解決。由于通風(fēng)管件及其部件在圖紙上都是幾何圖形，而對(duì)形體進(jìn)行分析的主要目的就是將復(fù)雜的幾何圖形簡(jiǎn)單化。通過(guò)分析，以便找到恰當(dāng)?shù)恼归_(kāi)方法。

For the more complex pipe fittings, it is necessary to read and analyze the construction drawings repeatedly, and put forward and solve the relevant problems in time. Because the ventilation pipe fittings and their components are geometric figures on the drawings, the main purpose of analyzing the shape is to simplify the complex geometric figures. Through the analysis, in order to find the appropriate expansion method.
