With the rapid development of the national economy and the continuous improvement of the technical level, almost all walks of life need to do exhaust ventilation systems, Qingdao rubber liner What are the advantages worth pursuing? 1. The welding method is unique. It adopts a new low temperature welding form, which does not damage the galvanized layer of the product. The welding spot is firm, the weld seam is beautiful, and the sealing is good. After welding, no treatment is required for the weld seam. 2. The manufacture of mechanically formed air duct makes the high-quality galvanized sheet not damaged, and the galvanized layer not damaged, thus prolonging the service life. 3. The specification is uniform and the size is standard, which ensures that the inner wall of the pipeline is flat and smooth, so that it is easy to clean and the material transportation is smooth. 4. The self forming flange can make the pipe material uniform, no longer use angle steel flange, and reduce the pipe weight by more than 20%, so the load bearing capacity of the building can be greatly reduced, thus reducing the overall cost of the building. 5. Enhance the beautiful pipeline, beautiful appearance, exquisite structure, smooth lines, superior performance, and the installation of exposed air ducts, especially suitable for this product. 6. Typical round air pipe fittings are generally 3-6 meters long and rectangular pipe fittings are 1-1.5 meters long, reducing the connection points of pipe fittings and minimizing the leakage at the joint of pipe fittings. 7. The pipe fittings, joints and spare parts made by mechanized assembly line all have standard sealing rings. As they are produced in a standardized and factory way, they have better air tightness. 8. Mechanically formed compression ribs and stiffeners can improve the strength of the pipe wall, save material thickness and reduce costs. The thickness of the seam of the spiral pipe is 4 times that of the pipe body, which makes the pipe very rigid and has the best pressure bearing performance, especially the negative pressure. 9. Scientific joint and seaming methods can ensure smooth pipeline gas without affecting pipeline flow diameter. Therefore, mechanized assembly line production improves production efficiency and effectively shortens delivery cycle. Advanced computer process control program blanking, production, rubber liner company It ensures the dimensional accuracy of pipeline components, thus ensuring fast and convenient installation and construction, and improving work efficiency and economic benefits.

production rubber liner The manufacturing of is highly automated and the production speed is very fast. The general air duct can produce 20~40 meters per minute. Due to the low price of its raw material galvanized strip steel compared with the whole galvanized steel sheet, and its factory production and specification standardization, the cost of spiral air duct is lower than that of rectangular air duct; In addition, the total cost of spiral air duct is low due to the less demand for supports and hangers and the less installation work. Since the four corners of rectangular air ducts are prone to turbulence, reducing the effective flow area, the spiral air ducts have good air fluidity and large effective flow area, so the secondary noise of spiral air ducts is low. Because the spiral air ducts are strong, the low-frequency noise caused by air duct vibration is smaller, the air flow performance is good, the system pressure drop is small, and the daily operation system consumes less power. Spiral air ducts in the market are generally divided into three categories according to their materials: galvanized spiral air ducts, stainless steel spiral air ducts and composite spiral air ducts. Among them, spiral air duct has the best quality and strong applicability, but its price is high. At present, the most widely circulated spiral air duct on the market is galvanized sheet. The galvanized sheet spiral air duct is basically the characteristic of stainless steel spiral air duct, but its price is only two thirds or even lower than that of spiral air duct. Qingdao rubber liner It is generally used in places where the external environment is relatively common and the requirements for air ducts are not too high. As the iron sheet is prone to chemical reaction in various environments, corrosion and rust will occur. However, zinc hardly changes in dry air. In humid air, dense basic zinc carbonate film will be formed on the surface of zinc. The spiral air duct is mainly coated with zinc on the iron sheet of the air duct to protect the iron sheet. The protective and decorative properties of zinc coating can be significantly improved after passivation treatment, dyeing or coating with light protecting agent.

We all know rubber liner 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 liner has been transformed. Through repeated tests and comparison, it is found that the noise generated by the rubber liner and the manganese steel liner of the ball mill is far less than the manganese steel liner 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). Qingdao rubber liner 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.
