China's spiral fan industry is developing rapidly. Many of the industry's overall models and associated spiral duct fan technology have changed dramatically. It can be said that the spiral duct industry has become the main force of China's industrial development.
1. Spiral duct machine has a wide range of applications. At present, China's aerospace, automotive, shipbuilding, energy, transportation, metallurgy, petrochemical, building materials, light industry electrical appliances, electronics and other industries have a strong momentum of development, providing a huge market for spiral duct machine industry.
2. Spiral duct machine industry has broad space for development. Spiral duct machine has the advantages of stable performance, easy installation, green environmental protection and low cost. It not only improves the efficiency of energy use, but also improves the safety of production equipment.
3. Spiral duct machine has the advanced technical support. With the progress of science and technology and the development of information technology, digital manufacturing, network technology and remote design and manufacturing technology are gradually applied to the production field of spiral duct machine.
4. Promote industrial policies of spiral duct machine. With the continuous upgrading of China's industry and the stimulus of economic transformation, the spiral duct industry actively adjusts its industrial structure. In the important period of economic transformation of the spiral duct, it grasps the market opportunity and realizes the leapfrog development of the industry by reducing operating costs, improving production efficiency and improving management concepts.
1. Gas washing: saw blade cutting automatic spiral duct machine through the hose connected to the air pipe conveying compressed air, and equipped with nozzle.
If light leakage is observed on the appearance of the spiral duct machine, it indicates that there is air leakage and it is necessary to repair the duct leakage.
The test method of the spiral duct machine is to move slowly from one end of the duct to the other end and observe the appearance of the duct leakage at the same time in a certain length of duct and dark environment, using the lamp with a protective cover and the duct with a voltage not greater than 36V and a power greater than 100W.
2. Vacuum cleaner: it is operated by a vacuum straw similar to a hand-held one. Automatic spiral duct cutting machine with saw blade cleans dirt by directly touching the inner wall of pipe with brush.
This method requires a saw blade to cut the duct of an automatic spiral duct with large holes so that the operator can get as much as possible. But this method may leak some dust and dirt because the duct cannot form a full negative pressure state.
The duct bite edge, rivet hole, corner leakage can be used sealant or other sealing measures. If the flange joint leaks, tighten the nut or replace the flange gasket according to the actual situation.
3. Dynamic cleaning of spiral duct machine: remove dirt with pneumatic or electric brush, and then clean it in the same way and direction with gas. The dirt is sucked into the saw blade to cut the automatic spiral tube vacuum cleaner. The method requires as much care as possible to avoid damaging the appearance of the insulating material.
