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：工作時通風管道漏風，空調(diào)負荷添加，同時風壽命和性能被影響。

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，不能滿意制造通風管道的需求。

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

④辦法：在使用通風管道加工設備制造通風管道前，要先查看資料出廠合格證書和資料質(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.

在應用前人們應當按時除去排煙風機里邊的塵士，特別是離心葉輪上的塵士、誤點等殘渣，以預妨生銹和失調(diào)。另一個還要盡量減少機器設備將會出現(xiàn)的一些常見故障，比如電級電流量很大或是溫度太高，滾動軸承箱猛烈超越這些，搞好預防工作中。

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.

通風管道展開步驟基本上可以分為熟悉圖形，形體分析，求直線的實長或平面的實形，確定展開方法和畫展開圖這幾個部分。在進行展開下料前，要熟悉施工圖紙，這是一項準備工作，主要是對將要展開的關鍵和部件有所了解，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.

而對于比較復雜的管件，則需要對施工圖紙進行反復閱讀和分析，針對有關問題要及時提出和解決。由于通風管件及其部件在圖紙上都是幾何圖形，而對形體進行分析的主要目的就是將復雜的幾何圖形簡單化。通過分析，以便找到恰當?shù)恼归_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.
