Fujian Flange rubber pipe 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. Flange rubber pipe 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.
Due to the limitation of spatial location conditions, production Flange rubber pipe The installation stress of can often bring various difficulties to the installation work: formed pipes cannot be installed; When you bend down, you are about to come. If you make do with pipes, local cold correction will inevitably occur. According to the size of the pipeline and the specific situation on site, the cold correction amount varies from several millimeters to tens of millimeters, some as high as hundreds of millimeters. Practice has proved that the greater the quantity, the higher the internal stress. These residual installation stresses in the rubber sand blasting pipe are undoubtedly huge hidden information. The lubricating oil duct of a certain type of engine bearing was broken for many times due to excessive installation stress in actual operation. Because it can be bent at will, the internal stress generated by bending under the condition of rated bending radius is very small, which brings great convenience to the installation work, and also plays a certain role in ensuring the safe operation of the rubber sand blasting pipe. This is the main reason why some rubber sand blasting pipes must be used. Since it is necessary to load and unload the mold, the movable cylinder on the vulcanizer will move up and down. After repeated reciprocation, the copper serpentine tube will undergo fatigue fracture. Although it can continue to be used after repair, stopping for repair will cause time loss. Fujian Flange rubber pipe Although it has good flexibility and strong fatigue resistance, it is also weak in pressure bearing, temperature resistance, aging resistance and other aspects, and can not be used after several months. The good comprehensive performance of rubber sand blasting pipe is fully reflected here.
production Flange rubber pipe The inner rubber layer of( ф 0.3-2.0 reinforcement layer) is the skeleton material that plays the role of reinforcement. What should be paid attention to when storing the wear-resistant sandblasting pipe. 1. The wear-resistant sandblasting pipe should be stored as loose as possible. Generally, rubber hoses with inner diameter less than 76 mm can be wound and stored. 2. During the storage of wear-resistant sand blasting pipe, it is strictly prohibited to stack heavy objects on the pipe body to prevent external extrusion and damage. 3. During the storage of wear-resistant sand blasting pipe, do not contact with acid, alkali, oil, organic solvent or other corrosive liquids and gases, and the heat release should start from 1m away. 4. The storage period of wear-resistant sand blasting pipe shall not exceed 2 years, and it shall be used by the first person to prevent the quality of rubber pipe from being affected by long-term storage. 5. When wear-resistant sand blasting pipes need to be temporarily stored in the open air, the site should be flat and the rubber pipe should be laid flat. The upper cover should be placed under the rubber pipe and no heavy objects should be stacked. At the same time, the hose shall not contact the heat source. 6. The storage place of the upper and lower rubber pipes in the well shall be kept clean and ventilated, and the relative humidity shall be 80. The temperature of the storage place shall be kept between - 15 ℃ and 40 ℃, and the rubber pipe shall be protected from direct sunlight and water spray. 7. When storing wear-resistant sand blasting pipe, Flange rubber pipe Price Both ends of the hose shall be sealed firmly to prevent sundries from entering the hose. 8. When the wear-resistant sand blasting pipe is stored, it should be placed separately according to different varieties and specifications, not mixed, and hang the management board. 9. In order to prevent the pipes from being pressed and deformed during storage, they should not be stacked too high, and the stacking height should not exceed 1.5m. It also requires rubber hoses to be "stacked" frequently during storage, at least once a quarter.
We all know Flange rubber pipe 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). Fujian Flange rubber pipe 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.
