The reason why welded air duct has become the favorite of the market, Lanzhou Corbel 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, Corbel tube company 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.

Let's take a look today Lanzhou Corbel 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 Lanzhou Corbel 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.

As the use time increases, wear-resisting Corbel tube A large amount of impurities will accumulate in the pipeline. These impurities stored in the pipeline for a long time will accelerate the condensation of oil, form pneumatic valves, damage hydraulic components, and have a great impact on normal operation. Therefore, it is very important to clean the stainless steel welded air duct regularly. How to clean impurities in stainless steel welded air duct? When the stainless steel welded air duct is connected with the fan, the inlet and outlet shall be provided with flexible joints. The size of flexible joint shall be the same as the inlet and outlet of fan. Hose joints are usually made of canvas, artificial leather and other materials. The hose length shall not be less than 200. Sealing shall be proper. Hoses dampen fan vibration. Before the welding air duct is connected with the dust removal equipment and heating equipment, and after the completion of the equipment, the prefabrication and equipment shall be stopped according to the theoretical mapping. During equipment installation, the inlet and outlet of stainless steel welded air duct shall be opened during prefabrication. If an air outlet is required at the end of the pipe, the connection shall be closed. When transporting natural gas containing condensate or water, the horizontal pipeline shall be inclined, and the drainage pipe shall be connected at the low point. Longitudinal joints do not apply to the bottom of the pipe. Sealing treatment shall be stopped for the bottom joint. For steel plate air ducts conveying flammable and explosive gases, cross connectors shall be installed at the connecting flanges of the air ducts and connected to the electrostatic grounding grid. When the height of the horizontal airway is more than 4m, the installation personnel shall fasten the safety belt. Corbel tube company The springboard on the scaffold or movable support shall be fixed. The width of the springboard shall meet the safety specifications. The installation personnel on the scaffold shall carry bags with them to prevent falling objects or electric drills from hurting people. After installing double hangers on the welded air duct, the cross arm shall be straight and the suspender shall not be replaced.

We all know Corbel tube company The noise pollution in industrial production is very serious, and noise pollution is also an important factor affecting workers' enthusiasm for production. Ball mills were once a major source of noise in mining equipment. In order to reduce the noise generated by ball mills, protect the physical and mental health of workers, improve workers' enthusiasm for production, and create greater profits for the company, Through the efforts and research of domestic and foreign industry experts, the ball mill lining plate has been transformed. Through repeated tests and comparison, it is found that the noise generated by the rubber lining plate and the manganese steel lining plate of the ball mill is far less than the manganese steel lining plate when the technical parameters are up to standard. According to the data provided by the noise monitoring station and the concentrator, We analyzed the noise intensity and the economic benefits: the domestic ND2 precision sound level meter and octave filter were used for detection, and the sound level meter was calibrated by the provincial sound level meter measurement and verification station; There is no sound insulation room in the ball mill workshop. The monitoring points are arranged according to the position of the ball mill and the flow of workers to observe the mechanical operation, 2m away from the sound source. One monitoring point is respectively set on the left and right of the east and west of the workshop and in the middle of the two ball mills. The measurement method is in accordance with the Noise Detection Specification for Industrial Enterprises. As the noise in the workshop is continuous and steady, sound level A is used as the evaluation basis. The rubber lining plate is manufactured by Hainan Rubber Lining Plate Factory according to the ball mill shell structure and the original manganese steel lining plate specification (1.4mx0.74mX0.07m). Lanzhou Corbel tube First, take out the manganese steel lining plate in the ball mill barrel, and then install the rubber lining plate in the barrel in turn (front and back). Each ball mill is installed with 48 pieces. First, use the pressure strip to compress, and then use the screws to fix the rubber lining plate on the ball mill barrel, so as to prevent falling off when rotating. The noise intensity of the ball mill workshop with manganese steel liner is 94-103dB (A), while the noise intensity of the ball mill workshop with rubber liner is 87-92dB (A), and the noise reduction difference is 7-11dB (A). The rubber liner has good noise reduction effect.
