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). Nanchang 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.

wear-resisting Oil resistant hose 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, Oil resistant hose 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.

The air conditioning in the hall of a giant building is provided by the 6FWB unit fixed in the basement. wear-resisting Oil resistant hose The vibration of the unit is transmitted to the ground hall through the bridge connecting the sand blasting hose pipe, and the noise value reaches 45dB. In such an environment, people always feel uncomfortable. After the improved design, sandblasting rubber pipes were connected in series on the connecting pipes, which not only absorbed some of the noise generated by the unit vibration, but also the noise generated by the fluid pulsation in the pipeline system. At this time, the noise value in the ground hall was only 33dB, greatly improving the environment in the hall. The movable cylinder on the vulcanizing press will move upward and downward for the need of loading and unloading the mold. After repeated reciprocating movements, the copper serpentine will suffer from fatigue fracture. Although it can still be used after repair, it will cause time loss if it is stopped for repair. Oil resistant hose Price Although it has good soft properties and strong fatigue resistance, it is weak in pressure bearing, temperature resistance, aging resistance and other aspects, and can not continue after several months of use. The good comprehensive performance of sand blasting hose is fully reflected here. In the general industrial field, in addition to pressure and temperature, there are often severe conditions such as fatigue, corrosion, vibration, compression, impact, etc. Under such circumstances, it is most appropriate to use sandblasting hose to compensate for the position movement of the pipeline.

Whether in the process of purchase or use, wear-resisting Oil resistant hose The quality of all needs to be checked regularly. During the inspection, the following items should be noted. 1. Standard size and actual error of high-pressure rubber hose: because the inner diameter and outer diameter of high-pressure sand blasting pipe and the outer diameter of the skeleton layer will shake, if the shaking amplitude exceeds the allowable limit, the balance of the buckling amount of the sand blasting pipe joint cannot be guaranteed, and the quality of the sand blasting pipe assembly cannot be guaranteed. Therefore, for the sand blasting pipe selected for the production of sand blasting pipe assembly, it is necessary to strictly check whether the inner diameter and outer diameter of the skeleton layer meet the requirements, and the requirements for the outer diameter error can be appropriately relaxed. 2. Wall thickness error of high-pressure hose: due to the local pain of the rubber layer in the high-pressure sandblasting pipe and the influence of the overlapping width of the rubber layer of the high-pressure sandblasting pipe quality inspection center between the skeleton layers, the wall thickness error of the sandblasting pipe may be too large. If the wall thickness error exceeds the allowable range, it will affect the tightness and pull-out strength of the connector, and even cause some deflection (tilting head) of the hose assembly connector. Quality inspection of high-pressure sand blasting pipe Therefore, the wall thickness error of sand blasting pipe should be strictly controlled. Generally, the rubber hose with wall thickness error exceeding 0.5mm shall be selected stably. 3. Adhesion between each layer of high-pressure rubber hose: high-quality high-pressure sand blasting pipe shall have prominent integrity, that is, the quality inspection of high-pressure sand blasting pipe shall have high adhesion between each structural layer, and the adhesion between each adhesive layer shall become an integrity. Only in this way can we meet various technical requirements in the process of joint installation and fastening, and only in this way can we ensure the quality inspection requirements of high-pressure sand blasting pipes for sand blasting pipe assembly. Therefore, Oil resistant hose Price It is necessary to control the adhesive force between each layer of the rubber hose not lower than that specified in the technical standard, and the rubber hose with high adhesive force shall be selected as far as possible to produce the rubber hose assembly.

If conditions permit, secondary vulcanization shall be adopted, wear-resisting Oil resistant hose Effectively remove the odor generated during the consumption of odorless hose. Pay attention to the volatilization of various ingredients in the odorless hose formula. When the odorless hose is consumed, in addition to paying special attention to the raw materials and vulcanization process of the reclaimed rubber, pay attention to the selection of various ingredients and whether they will volatilize in the vulcanization process. The volatilization of vulcanizing agent, accelerator and antioxidant will produce a great smell. It is very important to accurately determine the length of the required rubber sand blasting pipe by using the rubber sand blasting pipe. It shall also be checked whether the use conditions of the rubber sand blasting pipe meet the requirements of the selected rubber sand blasting pipe. It should be ensured that the rubber sand blasting pipe you will use is the most suitable one. The working pressure and suction should be carefully determined. Special attention shall be paid to the test standard pressure change or pressure peak of wear-resistant sand blasting pipe. Exceeding the promised maximum value will greatly shorten the service life of the rubber sand blasting pipe. Both ends of the rubber sand blasting pipe cannot be continuously immersed in the transported material. If the bending radius of the rubber sand blasting pipe is less than the minimum value, Nanchang Oil resistant hose Its service life will be greatly shortened. Therefore, before installation, it is recommended that you consult the application of information, especially the information about the bending radius of the rubber sand blasting pipe. Protection and cleaning of rubber sand blasting hose: it is recommended to empty the hose after use. Clean if necessary. Inspection: After each use, the rubber sand blasting pipe must be inspected to ensure that it does not show structural damage.
