Nanning Oil resistant hose 1. The manufacturing quality shall be guaranteed according to the national standards of Oxygen Hose (GB/T2550-91) and Acetylene Hose (GB/T2551-91) respectively, and the hose shall have sufficient compressive strength and flame retardant characteristics. According to the national standard, the oxygen hose is red, the working pressure vessel is 1.5MPa, the inner diameter of the hose is 8mm, and the outer diameter is 18mm; 2. Care must be taken when storing and using the hose to keep it clean and free from damage. For example, avoid exposure to sunlight, rain and snow, and prevent contact with substances such as acid, alkali, oil and other organic solvents that can damage the hose. The storage temperature shall be - 15 ℃~40 ℃, and the distance from the personnel shall not be less than 1m; 3. When using a new hose, the talcum powder on the inner wall of the hose must be blown out first to prevent the channel of the welding torch from being blocked. Avoid external extrusion and mechanical damage during use, and do not fold the pipe body. 4. If the oxygen hose catches fire, stop the air supply first, and then deal with the fire hose, but do not bend the hose. The cylinder valve must be closed when the cylinder is not in use or after work. 5. The hose with bulge, crack or air leakage shall not be used, and the air leakage hose shall not be used after being stuck with adhesive tape. Oil resistant hose Price When connecting the two ends of the hose with tools, clamp or wire shall be used to fasten, and the intermediate joint shall be fastened with a gas pipe connector.
Oil resistant hose Price Precautions ① The acid and alkali resistant rubber hose used shall not only be oil resistant, but also be pressure resistant, heat resistant, cold resistant, wear resistant and aging resistant. ② The rubber hose should not be too long or too short, generally 1.4 meters. ③ The interface is tight and can be fastened with thin iron wire or clip to prevent falling off and air leakage. ④ It is forbidden to pull acid and alkali resistant rubber hose from one room to another or through walls, floors and floors to prevent accidents caused by rubber hose breaking and falling off. ⑤) The acid and alkali resistant rubber hose should be placed in a place where it can be seen frequently, so that it is easy to detect leakage. Check whether the rubber hose leaks after each bottle change. ⑥ Do not replace acid and alkali resistant rubber hose with universal rubber hose. Since the full rubber hose does not contain a skeleton layer, it is only necessary to use a press out machine to press out the hose; The cloth clamping hose needs to use a molding machine that wraps the adhesive tape on the inner adhesive layer; When forming the suction hose, first wrap the metal spiral wire and then wrap the inner rubber; Special fabric knitting machine or winding machine shall be used for knitting and winding hose; Knitting machine is required for knitting hose. Nanning Oil resistant hose The basic production processes include rubber mix processing, cord fabric and canvas processing, rubber tube molding, vulcanization, etc. The manufacturer of acid and alkali resistant rubber hose said that the processing method of the skeleton layer and the forming equipment of the rubber hose are different for different structures and different skeletons.
We all know Oil resistant hose Price 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). Nanning Oil resistant hose 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.
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, Nanning Oil resistant hose 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, Oil resistant hose Price It ensures the dimensional accuracy of pipeline components, thus ensuring fast and convenient installation and construction, and improving work efficiency and economic benefits.
