Stamping spiral pipe is widely used

Stamping spiral pipe is widely used The traditional pipeline will destroy its own continuity after punching, resulting in pipeline deformation, deformation and even fracture, which will seriously damage its ventilation effect. If it is replaced with spiral tube, it is necessary to ensure not only the punching effect, but also the tube stiffness and hardness under the action of spiral bone. After testing, the hardness of spiral duct fan is three times that of traditional ductless equipment, so it is widely used in laboratory and other fields.Pipe reinforcement is to ensure its performance, but not all pipes need reinforcement. Except spiral pipe, the diameter of round pipe is greater than or equal to 80mm, the pipe length is more than 1250mm, and the total area is more than 2M2, which needs to be reinforced; The side length of rectangular pipe is greater than 630mm, the side length of insulated pipe is greater than 800mm, the pipe length is greater than 1250mm, or the unilateral area of low-pressure air duct is greater than 1.2m2, and the medium and high-pressure pipes are greater than 1m2. Bolts, nuts, washers and rivets selected by the pipeline shall be made of materials that meet the performance of the pipeline and do not produce electrochemical corrosion or galvanization or other anti-corrosion measures. Blind rivets cannot be selected. Reinforcement frame and reinforcement shall be adopted. The pipeline shall not be connected by flange, and the forms of S-shaped cutting, right angle cutting and vertical cutting shall not be used. In the installation and construction of underground works, the mature use of complete sets of production equipment such as automatic production line of spiral air duct, plasma cutting machine, circular elbow forming machine and caulking welding machine makes the production of circular air duct change from manual operation to mechanized and automatic operation; The development and application of supporting construction technologies such as connection of inner expansion core pipe without gasket and the introduction and improvement of construction machinery have increased the installation and construction efficiency of spiral air duct several times. These technologies and equipment improve the quality, speed and appearance technology of ventilation engineering construction, and promote the overall development of spiral duct installation and construction technology.

Application scope of air duct production machine

Application scope of air duct production machineMany customers don't know much about duct fan equipment, but it appears in all aspects of our life, so it's better to understand it. The following spiral duct fan manufacturers to talk about the scope of use of spiral duct fan.The name depends on its purpose, but it can be used in other places, even drainage, drainage or container, so it can not be called air pipe. According to the structure, it should be named a spiral slit thin-walled tube. Because it is mainly made of metal, it is called spiral bite metal tube. If the material is named, there may be several names: galvanized (iron) spiral air duct machine, stainless steel spiral air duct machine, aluminum screw cyclone pipe machine, or in order to distinguish from the existing stainless steel pipe, it can be called thin stainless steel pipe, because it can be made of 0.3mm or even thinner stainless steel.Many people are not very familiar with spiral duct. In fact, spiral duct fan is widely used. Air supply and return duct of purification system, air conditioning system in air duct, ventilation duct ventilation, environmental protection system, exhaust pipe, mine gas pipe, mine adhesive tape pipe, etc. Because spiral wind turbine was originally used for ventilation and cooling, it is classified as air duct. Without increasing any pressure drop, a circular pipe with a diameter of 200mm can be replaced by a rectangular pipe with a diameter of 250 * 150mm in the same installation space. Without additional installation space, several parallel circular pipes can replace rectangular flat pipes.Considering all factors, in most cases, circular pipes occupy less space than rectangular pipes. For the same pressure characteristics, the installation space of several circular pipes is often the same or smaller than that of rectangular pipes. Many rectangular piping systems require four bolt systems for installation, so an increase of 40 - 80mm. In all directions of the pipeline.Without increasing any pressure drop, a circular pipe with a diameter of 200mm can be replaced by a rectangular pipe with a diameter of 250 * 150mm in the same installation space. Without additional installation space, several parallel circular pipes can replace rectangular flat pipes.

What should be paid attention to in the reasonable electricity use of the spiral duct machine

What should be paid attention to in the reasonable electricity use of the spiral duct machine 1) Good product compatibility and high standardization;2) Strong airtightness;3) Low ventilation loss; low ventilation noise, round pipe is better than square pipe.4) Convenient factory inspection;5) Anti-balanced external pressure (negative pressure) program;6) Material province;7) Easy installation, few connection points, small installation space and low installation cost.8) The overall installation layout is beautiful and high-grade.9) It is convenient for daily maintenance and cleaning.10) The section has a small wet circumference, low resistance along the way, and less energy loss.11) Fully mechanical processing, no secondary processing is required for one-time molding.12) High-speed flying cutting machine with high pipe diameter.13) Adopting four methods: reducing diameter socket, sleeve interconnection, flange interconnection, and strap interconnection, making the installation more convenient.14) The external insulation quality of the pipe is better than that of a rectangular duct.
