The reason why welded air duct has become the favorite of the market, Jiaxing Oxygen tube Compared with the air duct made of traditional materials, it has obvious advantages in technology, energy conservation, environmental protection and economy. This product has been inspected, tested and proved by the National Building Materials Testing Center, the National Fire Building Materials Quality Supervision and Inspection Center, the National Air Conditioning Equipment Quality Supervision and Inspection Center, the National Non ferrous Metal Quality Supervision and Inspection Center and other relevant authorities, In addition, no smoke is generated in the fire, and the smoke density is only 4, which is 10 to 20 times that of other organic foam materials. In modern buildings, central air conditioning is very common, and ventilation ducts are an important part of the central air conditioning system. According to statistics, China's annual demand is about 100 million square meters, reaching 20 billion yuan. Among all kinds of air ducts, welded air ducts stand out for their unique excellent performance and cost performance, and are becoming the new favorite in the central air-conditioning market. The manufacturing of welded air ducts is highly automated and the production speed is very fast. Ordinary air ducts can produce 20~40 meters per minute. Due to the low price of the raw material galvanized strip steel compared with the whole galvanized steel sheet, and its factory production and specification standardization, the cost is lower than that of rectangular air ducts; In addition, the total cost is low due to the less demand for supports and hangers and the less installation work. Since the four corners of rectangular air duct are prone to turbulence, Oxygen tube Where can I find it? The effective flow area is reduced. The technology of welded air duct is very close to the international level; In terms of supporting services, more and more enterprises like this company provide high standard services. If there are any suggestions, we hope to see more and more enterprises with a sense of mission for the development of the industry.

Oxygen tube Where can I find it? It has become the standard configuration of the modern new ball mill, but many problems may occur during the use or installation of the rubber lining plate, which will cause the failure of the rubber lining plate of the ball mill. Here is a brief introduction to the causes of the more common failure of the rubber lining plate of the ball mill. The design and installation are not professional and reasonable. The design and installation are also common problems for many novice manufacturers. For example, the bolt holes for fixing the ball mill lining plate are square, which will cause stress concentration and fracture. Adjust the size of lining plate to control the gap between lining plates at about 8mm; The installation quality of lining plate is very important to the safe operation of ball mill. First, tighten the fixed wedge symmetrically, put the lining plate in sequence, and then use the tightening wedge to secure it; Therefore, professional installation guidance can easily avoid these problems. The reason why the rubber lining plate of the ball mill does not match the steel ball is relatively common, and it is easy for many novice manufacturers to ignore and make mistakes. During the operation of the ball mill, the rubber lining plate of the ball mill, materials and steel balls promote the normal grinding and crushing of the ball mill due to the interaction of forces. The hardness of materials is related to wear resistance, and the wear resistance increases with the increase of hardness, Jiaxing Oxygen tube It is a pair of friction pairs, and the increase of hardness of one side will cause the wear of the other side to increase. Therefore, the high wear-resistant rubber lining plate is matched with the high wear-resistant steel ball, and the low wear-resistant rubber lining plate is matched with the low wear-resistant steel ball, so as to ensure the normal wear of the rubber lining plate of the ball mill and extend the service life of the ball mill.

Let's take a look today Jiaxing Oxygen tube How should the maintenance work be done? Firstly, the thickness of galvanized air duct splice plate shall be within the range specified in various specifications. If it is less than the thickness, it is easy to have defects such as cracking and wrinkling due to significant increase of bending force, abnormal damage of forming roll, overload of transmission system, boring, etc. Secondly, in the dedusting system: galvanized air ducts can be used for the collection and transportation of dedusting devices. In terms of air exhaust system: there is a large amount of smoke in the dining room, dining room and hotel kitchen, which needs air exhaust. The galvanized pipe is more appropriate, with good strength, economy and practicality. In air conditioning system: galvanized air duct can be pasted with thermal insulation materials, and the surface is beautiful. In bulk material transportation: in the pneumatic conveying system, some materials with fine loose particles can be transported by galvanized pipes, which has low cost and good effect. In the ventilation system: fresh air is supplied and discharged, harmful gases are discharged outdoors, and outdoor fresh air is sent indoors. The strength of stainless steel plate is greater than that of ordinary steel plate. When stainless steel plate is used for seaming, first of all, a forming test should be carried out to avoid overloading of equipment and excessive wear or mechanical problems. Due to the poor plasticity of aluminum plate, it is easy to crack when biting into forming. Forming test shall be conducted before construction. The last point is that the protection and decoration of the galvanized layer of the galvanized air duct can be significantly improved after passivation treatment, dyeing or brushing light protective agent. and Jiaxing Oxygen tube The fire prevention function of is mainly reflected in that it is nonflammable, but it should be noted that whether the insulation layer is burned depends on the material. We recommend that galvanized air duct materials use nonflammable insulation materials such as centrifugal glass wool.
