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 Performance: the surface of the plate is not smooth, the thickness is not uniform, there are significant indentation, cracks, sand holes and corrosion, etc; The plane of the ventilation duct sinks, and the side of the ventilation duct protrudes outward, with significant deformation.
② Impact: air leakage in ventilation duct, air conditioning load increase, and air life and performance are affected.
③ Cause: the data is not qualified, and the requirement of manufacturing ventilation duct is not satisfied.

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.
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.
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.
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.
