专注通风管道加工·排烟罩

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表现：板材外表不平整，厚度不均匀，有显着的压痕、裂纹、砂眼和锈蚀等情况;通风管道平面下沉，旁边面向外凸起，有显着的变形。

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影响：工作时通风管道漏风，空调负荷添加，同时风寿命和性能被影响。

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

③原因：资料不合格，不能满意制造通风管道的需求。

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

④办法：在使用通风管道加工设备制造通风管道前，要先查看资料出厂合格证书和资料质量证明还有外观厚度等，确保资料是可用的。

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.

在应用前人们应当按时除去排烟风机里边的尘士，特別是离心叶轮上的尘士、误点等残渣，以预妨生锈和失调。另一个还要尽量减少机器设备将会出現的一些常见故障，比如电级电流量很大或是温度太高，滚动轴承箱猛烈超越这些，搞好预防工作中。

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.

通风管道展开步骤基本上可以分为熟悉图形，形体分析，求直线的实长或平面的实形，确定展开方法和画展开图这几个部分。在进行展开下料前，要熟悉施工图纸，这是一项准备工作，主要是对将要展开的关键和部件有所了解，如管道在图纸上的尺寸大小、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.

而对于比较复杂的管件，则需要对施工图纸进行反复阅读和分析，针对有关问题要及时提出和解决。由于通风管件及其部件在图纸上都是几何图形，而对形体进行分析的主要目的就是将复杂的几何图形简单化。通过分析，以便找到恰当的展开方法。

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.
