Ventilation duct processing is an important part of ventilation and air conditioning system, most of which are made by duct processing equipment (such as duct production line). However, due to various reasons, it may lead to problems in the air duct processed by air duct processing equipment.
1. Processing data not up to standard
(1) Performance: the surface of the board is not smooth, the thickness is not uniform, there are obvious indentation, cracks, sand holes, scab and rust, etc.; the plane of the air duct sinks, the side faces to the outside, and has obvious deformation.
(2) Impact: air leakage in the air duct, air conditioning load increases, and the number of air life and performance are affected.
(3) Cause: the data is not qualified, and the requirement of manufacturing air duct is not satisfied.
(4) Method: before using the air duct processing equipment to manufacture the air duct, we should first check the data factory certificate, data quality certificate and appearance thickness to ensure that the data is available.
2. Air duct warping angle and elbow angle are not accurate
(1) Performance: two relative planes and two end faces of rectangular air duct are not parallel; inflection angle is not straight; diagonal line is not equal; bite is not tight.
(2) Influence: it will make the air duct connection stress uneven, the air duct after installation is not straight, the flange gasket is not tight, the system air leakage, resulting in air conditioning load loss, and shorten the service life.
(3) Reasons: the layout of plate cutting is not accurate; the air duct is parallel to each other, and the sheet metal length and width on the opposite side are not equal.
(4) Methods: when blanking, the sheet metal should be strictly angled, and the length, width and diagonal lines of each sheet should be checked to make their deviation within the allowable range; after blanking, the two sheets opposite to the air duct should be overlapped to check the dimensional accuracy.
