We can see the presence of ventilation ducts in many residential buildings and office buildings, but what we don't know is that there will be many problems in the processing of ventilation ducts, which annoy many workers. Let's learn about the problems and solutions that often occur in the processing of ventilation ducts in Jinan. Let's have a look.
1. The warping angle and elbow angle of the ventilation pipe are not allowed
Performance: the bending angle is not straight; Two opposite planes and two end surfaces of rectangular ventilation duct are not parallel; Loose bite; The diagonals are not equal.
Cause: the ventilation duct is parallel in two and the length and width of the opposite sheet are not equal; The setting out of plate blanking is inaccurate.
Impact: it will cause uneven stress of ventilation pipe connection, uneven ventilation pipe after installation, loose flange gasket, air leakage of the system, loss of air conditioning load, and shorten service life.
Measures: during blanking, strictly control the angle of the sheet, check the length, width and diagonal of each sheet, and control their deviation within the allowable range; After blanking, the two sheets on the opposite side of the ventilation duct shall be overlapped to check the dimensional accuracy.
2. The processing materials of ventilation pipes are not up to standard
Performance: the plane of the ventilation duct sinks, the side bulges outward, and there is obvious deformation; The surface of the plate is uneven, the thickness is uneven, and there are obvious indentation, crack, sand hole, scar and rust.
Reason: the materials are unqualified and cannot meet the needs of manufacturing ventilation ducts.
Impact: during operation, the ventilation duct leaks air, the air conditioning load increases, and the air life and performance are affected.
Measures: before using the ventilation pipe processing equipment to make the ventilation pipe, the factory certificate of material, the material quality certificate and the appearance thickness should be checked first to ensure that the material is available.
I have told you the solutions to these two problems. I hope you can apply them to the practice process.
