Ventilation Pipe Production in the two common problems

Ventilation ducts are an important part of ventilation and air conditioning systems, and most are made of ductwork equipment. But due to a variety of reasons, may lead to processing out of the duct problem, the following is to understand what are the problems.

First, the processing of materials is not up to standard
A performance: sheet surface is not smooth, uneven thickness, there are obvious indentation, cracks, trachoma, scarring and corrosion, etc .; duct surface sinking, the side outward bulge, there are obvious deformation.
B Effects: air duct air leakage during operation, air conditioning load increases, while the wind life and performance are affected.
C reasons: material failure, can not meet the needs of the production duct.
D measures: the use of wind pipe manufacturing equipment before the production of air duct, the first inspection of materials factory certificate and material quality certification, as well as the appearance of thickness, etc., to ensure that the material is available.
Second, the wind pipe angle and elbow angle are not allowed
A performance: rectangular air duct two opposite plane, both ends of the non-parallel; angle is not straight; diagonal unequal; bite lax.
B influence: the air duct will connect the force is not uniform, the installation of the duct is not straight, the flange gasket is not tight, the system air leakage, resulting in air conditioning load loss, and shorten the service life.
C reason: board under the lofting is not accurate; ducts parallel to the opposite side of the sheet length and width are not equal.
D measures: the start of cutting, the sheet should be strictly square, the length of each sheet, width, and test the diagonal, so that their deviation in the allowable range; after cutting the sheet, the wind The two plates on the opposite side of the tube coincide to verify dimensional accuracy.
So in order to produce the ducts practical and durable high-quality, it must be in the wind pipe processing equipment before and after the operation of adequate pre-and operational preparation to ensure foolproof and reduce unnecessary losses.
