Changsha Rubber hose The break of the sandblasting hose usually refers to the appearance and change of the crack of the sandblasting hose. The sandblasting hose has one or more cracks, but the cracks are neat. Another is that the internal bending cracks at the crack of the sandblasting hose are neat. The causes of different errors are different, and the treatment methods are also different. Therefore, in the process of using or protecting the sandblasting hose, the sandblasting hose should not be subject to changing torque. When installing the sandblasting hose, try to keep the axis of the two joints on the same plane to avoid twisting the sandblasting hose in use. Therefore, be careful with the application, and try not to make the sandblasting hose change excessively to avoid consumption. Sand blasting hose plays a very important role in the industry. Its inner rubber layer is added with carbon black, which can effectively eliminate static electricity and directly contact with compressed air and abrasives. The requirement for wear resistance is quite high. Once worn through, the reinforcement layer will be exposed, and the sand blasting hose will burst. The reinforcing layer of sandblasting hose is a pressure resistant layer, so high quality Rubber hose The material and layout of the reinforcement layer directly determine the pressure rating of the sandblasting hose. There are two common enhancement layers: cloth clip enhancement layer and surround enhancement layer. The sand blasting hose with an inner diameter of 50mm or more is mostly used in the construction occasions where the sand blasting pipe needs to be extended to reduce the pressure loss in the sand blasting hose and ensure the normal operation of shot blasting.
Whether in the process of purchase or use, high quality Rubber 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, Rubber hose company 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.
As high quality Rubber hose As an important part of sand blasting machinery, its safety plays a vital role in the safety of equipment operation. The following will briefly analyze the precautions in the use of high-pressure sandblasting pipe: I. Pipe inner diameter: inner diameter of high-pressure sandblasting pipe. 2、 Attention shall be paid to the following items in the use and design of high-pressure sandblasting pipe: 1. The bending radius of high-pressure sandblasting pipe shall not be too small, and generally shall not be less than the value specified in the assembly technology of high-pressure sandblasting pipe. The joint between the high-pressure sandblasting pipe assembly and the pipe joint shall have a straight section, and its length shall not be less than twice the outer diameter of the pipe. 2. The length of high-pressure rubber hose assembly shall consider that the high-pressure rubber hose will shrink and deform after introducing pressure oil. Generally speaking, the shrinkage rate is 3~4 times of the pipe length. When installing the high-pressure rubber hose assembly, it is not allowed to bear tension. 3. During installation, the high-pressure sandblasting pipe assembly shall be free from torsional deformation. Rubber hose company The connecting shaft of shall be placed in the moving plane as far as possible to avoid damaging the high-pressure sandblasting pipe when both ends move with each other. 4. High pressure resistant sand blasting pipe shall avoid contact and friction with mechanical sharp corners to avoid damaging the pipe. Safety measures: to ensure the safe and reliable use of high-pressure sandblasting pipe assembly.
1. The use of protection cannot be ignored: the long-term use of high-pressure sand blasting hose joints at home usually does not cause concern, but excessive use and improper protection also buried the hidden danger of joint cracking to a certain extent. It is understood that the service life of the joint is usually 200000 times, and it should be replaced after long-term use. When using the side, Rubber hose company Care should be taken to close and open as gently as possible and not to rotate the knob of the hose connector repeatedly. 2. Differentiation of quality can be based on standard evidence collection. It is understood that it is still difficult to determine the cause of joint cracking. At present, the National Bureau of Technology and Quality Supervision has issued recommendations for sealing nozzles and hose specifications. These two specifications perfectly adjust the quality specification target of connectors and hoses. Consumers can go to the quality inspection department to check the torsional strength of the connecting hose, the tightness of the connecting spool and the strength of the connecting materials. If the content of standard rules cannot be met, it will be attributed to quality problems, which can serve as a strong basis for expression. 3. The appearance of hose connector is difficult to distinguish between good and bad. In order to pursue profits and reduce costs, many manufacturers currently use selected cast iron (easy to rust) and zinc alloy (non anti-corrosion) as materials to produce high-pressure sand blasting hose joints, which causes product quality problems. It is understood that the quality of connectors and hoses is not up to standard, Changsha Rubber hose The strength function and sealing function of high-pressure sand blasting hose joints are not up to standard due to problems such as materials and wall thickness, which should be paid attention to by consumers.
high quality Rubber hose Or PVC steel wire spiral reinforced pipe. The commodity is made of high-quality PVC plastic raw materials. PVC steel wire reinforced pipe is also a PVC steel wire reinforced hose that uses steel wire reinforcement. The embedded spiral steel wire is used as the reinforcement layer, so the product has both rigidity and flexibility, that is, it has both satisfying mechanical properties and rigidity, and excellent flexibility. The reinforced pipe of latex fiber is PVC hose embedded with steel wire framework.

The application methods are different in different environments. The new PVC steel wire pipe is the most widely used commodity today. Rubber hose company After use, it will not be the same as the metal pipe, which is easy to deform and leak. What advantages does the PVC fiber reinforced pipe have.
Changsha Rubber hose It is used for transportation, construction and other operating equipment. Incorrect operation and incorrect environment may affect the normal use of steel braided sandblasting pipe. What specific factors will affect the normal use of steel braided sand blasting pipe? The quality will definitely affect the use effect. The poor quality is actually related to the selected raw materials. Some raw materials are of high quality, and the quality of steel braided sandblasting pipes produced is also very good. However, if the steel braided sand blasting pipe is made of inferior plastic, the quality is very poor, which also affects the use effect. The use environment affects the use effect. Anti static steel braided sand blasting pipe is usually used in industry. Because these products are very common, the demand is also large. However, people do not pay attention to the use environment. If used in strong acid and alkali environment, steel braided sand blasting pipe will naturally corrode. Or if used in a relatively high temperature area, the steel braided sandblasting pipe may melt. Anti static steel braided sand blasting pipe will also affect the use effect. In the eyes of most users, the greater the degree, the better the nature. So if you choose a good one, users can use it with confidence. Understanding and avoiding the wrong use of high-pressure pipeline can reduce the possibility of high-pressure pipeline failure. The following brief introduction will help you. 1. Frequent and serious pressure shock: high-pressure pipeline burst is generally not caused by excessive static pressure, but is related to the severity and frequency of pressure shock. During the operation of construction machinery, the sudden increase or decrease of oil pressure in the high-pressure pipe will occur repeatedly, which will cause frequent pressure shocks to the oil pipe, leading to the aggravation of oil seal damage at various parts, blistering and cracking of rubber hose, and loosening and leakage of pipe joints. Therefore, during operation, the valve rod shall not be pulled too hard, but must be pulled gently. 2. The use temperature of oil is too high: during the operation of construction machinery, due to the power loss of the hydraulic system, the oil will rise, and the external temperature (especially in summer) will lead to a sharp rise in the oil temperature. high quality Rubber hose company The higher the oil temperature is, the easier the rubber is to age, the worse the elasticity is, the lower the strength and sealing performance are, and the high-pressure pipe will burst rapidly. Therefore, when the temperature rise of the hydraulic system is too high or too fast during operation, the causes should be found out and eliminated in time. For summer operation, especially continuous operation, necessary cooling measures shall be taken.
