We all know Sandblasting 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). Kaifeng Sandblasting 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.
Whether in the process of purchase or use, high quality Sandblasting 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, Sandblasting 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.

In the application of different industries, according to their own needs, check the performance of the products, give proper play to the advantages of the products, and ensure the normal use of daily applications. When replacing the wear-resistant sand blasting pipe, the length of the rubber pipe, the number of steel wire layers, the shape and size of the joint should be reasonable, and the curvature of the rubber pipe should be minimized. When tightening the connecting nuts, do not tighten the rubber hose. Excessive bending and twisting will greatly reduce the service life of the rubber hose. Protective measures shall be taken for the parts liable to friction to prevent the rubber hose from bursting due to wear. What should we pay attention to when purchasing wear-resistant sandblasting pipe? Different types of wear-resistant sand blasting pipes have different working pressures. When purchasing rubber hose, you should first determine the working pressure of the system, Sandblasting hose Price Then select the equivalent working pressure of the hose. If the system is often affected by pressure, it is necessary to increase the working pressure of the hose and choose the hose with higher pulse life. The inner diameter of wear-resistant sand blasting pipe is one of the factors to be considered when selecting rubber hose. The small inner diameter will increase the flow rate of the medium, raise the temperature of the system, reduce the working efficiency, and affect the working performance of the system. The large inner diameter will increase the purchase cost. Therefore, the proper inner diameter should be selected according to the flow rate of the medium. The wear-resistant sand blasting pipe has allowable operating temperature range. The service life and pressure bearing capacity of the rubber pipe can be guaranteed only when it works at an appropriate temperature. When the operating temperature of the equipment exceeds the allowable temperature range of the rubber hose for a long time, special rubber hose shall be purchased or special protective sleeve shall be added on the wear-resistant sand blasting pipe. If the medium to be transported is special, make sure that the hose material is compatible with the medium.

Kaifeng Sandblasting hose Vulcanization of technical performance indicators is an important process to enhance the adhesive strength between rubber and reinforcement layer and make it a whole in rubber hose manufacturing, and also an important link to ensure and improve product quality. In order to obtain good pulse performance and service performance of steel wire reinforced rubber hose, in addition to reasonable structure and formula, it is necessary to ensure the compactness of vulcanized hose. In order to meet this performance requirement, the traditional vulcanization method is to wrap the water in water cloth on the semi-finished hose before vulcanization, make braided hose or steel wire for reinforcement and fastening, and vulcanize in batches with steam vulcanization tank. Since the performance requirements of medium and low pressure hoses are low, the rubber hose can also be directly put into the curing tank without fastening. Although water wrapped cloth vulcanization can also increase the compactness of the hose, its appearance is poor. In order to obtain the smooth outer surface of the hose, the lead coating vulcanization method is widely used at home and abroad. For decades, people have been using this method as an effective method to vulcanize and strengthen rubber hoses, especially high-pressure rubber hoses. So far, many domestic and foreign manufacturers are still using this method to produce rubber hoses. But the fatal disadvantage of this method is that it pollutes the environment.
