Many places will choose to install ventilation ducts, because the ventilation ducts themselves have the advantage of purifying the air, and more and more people begin to closely contact the ventilation ducts. What are the possible pipeline problems during the processing of pipeline equipment? What else to consider?
不允許彎管和彎角
Bends and corners are not allowed
原因:板下料放樣不準確,排氣管平行成兩條,板長和板寬不相等。
Cause: the blanking and setting out of the plate is not accurate, the exhaust pipe is parallel in two, and the plate length and width are not equal.
性能:長方形通風管有兩個相對的平面,兩端不平行,拐角不直,對角線不平,咬合不嚴。
Performance: the rectangular ventilation pipe has two opposite planes, the two ends are not parallel, the corners are not straight, the diagonals are uneven, and the bite is not tight.
Effect: uneven stress of ventilation pipe connection, uneven ventilation pipe after installation, loose sealing of flange plate, air leakage of system, resulting in air conditioning load loss and shortening service life.
Methods: when unfolding and blanking, the plates shall have strict edges and corners, and the length, width and inspection diagonal of each plate shall be strictly controlled to control the deviation within the allowable range; After blanking, the two plates opposite to the vent pipe shall be overlapped diagonally to check the dimensional accuracy.
加工材料不合格
Unqualified processing materials
原因:原材料不合格,不能滿足制造通風管的要求。
Cause: the raw materials are unqualified and cannot meet the requirements for manufacturing ventilation pipes.
Performance: uneven plate surface, uneven thickness, obvious indentation, crack, sand hole, rust, etc; The plane of the ventilation pipe is sinking, the side is protruding, and the deformation is obvious. During operation, the ventilation duct leaks, which increases the air conditioning load and affects the fan life and operation performance.
Methods: before using the ventilation pipe processing equipment to manufacture the ventilation pipe, check the material factory certificate, material quality certificate and appearance thickness to ensure that the materials are complete.
通風管道的主要考慮因素有哪些?
What are the main considerations for ventilation ducts?
Ventilation duct mainly includes air outlet, air duct, air door, air equipment and some accessories. The galvanized round flange mainly emphasizes the precautions for the operation of the ventilation duct and the damper in the ventilation duct system: it is the identification of the air duct. Before the reconstruction of air duct, one of the contents is clear, that is, the elevation of air duct. When viewing with the height adjustment command, sometimes the results displayed will be different. This is because the pipe and the elevation of the pipe are the center elevation of the pipe. Pipes are considered pipes as long as they are high.
With its good performance and low operating cost, it is widely used in shipbuilding, ventilation, air conditioning, purification, bridge dust removal, airport, tunnel and other construction industries. Air conditioning ducts are often used for the supply of cold and hot air, and insulation materials are required. It can also be pasted with thermal insulation materials to make the air duct spiral beautiful, avoid ceiling and reduce project cost. Compared with traditional air duct, spiral air duct has obvious advantages in technology, energy saving, environmental protection and economy, so it has become the darling of the market.
Compared with traditional air ducts, the advantages of spiral air ducts at present, most stainless steel air duct enterprises started late and have limited financial strength. However, in order to gain a place in the market, they launched a price war.
Jinan ventilation pipe processing itself adopts welding process. After strict inspection, it can be assembled according to customer requirements. A variety of utility programs (commonly used clamp and flange) can fully ensure the stable operation of the equipment. Long service life and small floor area. Manufacturing process characteristics and advantages of galvanized sheet spiral air duct installation and construction conditions of stainless steel: the installation of stainless steel welded air duct exhaust system and ventilation pipe of air conditioning system generally needs to be completed on the roof of the building, and the obstacles in the installation site have been cleared.
