Xiamen Suction pipe Also called rubber hose for sand blasting. It is suitable for air pressure sand blasting of metal surface for rust removal, hemp removal, and sand blasting rubber hose for wet sand blasting and dry sand blasting in engineering construction. It is suitable for air pressure sand blasting of metal surface for rust removal, hemp removal, and sand blasting rubber hose for wet sand blasting and dry sand blasting in engineering construction. The common application fields are shipbuilding, machining, spraying industry, etc. Appearance of abrasion resistant sand blasting rubber hose: 1. Light abrasion resistant sand blasting rubber hose consists of black, yellowish or transparent abrasion resistant rubber inner layer, central fabric or cord reinforcement layer, medium rubber layer and outer rubber layer; 2. Heavy abrasion resistant rubber hose consists of black, yellowish or transparent abrasion resistant rubber inner layer, cloth clip or cord reinforcement layer, steel wire framework reinforcement layer, medium rubber layer Composition of outer rubber layer 3. The steel wire braided wear-resistant sandblasting hose is composed of black, yellowish or transparent wear-resistant rubber inner layer, single-layer or multi-layer steel wire braided reinforcement layer, medium rubber layer and outer rubber layer. Purpose Abrasion resistant sand blasting hose is a kind of material conveying pipe, which is mainly used for conveying solids containing particles such as particles, gravel, cement, quicksand, mud, gypsum, etc. It is suitable for various tunnel projects, tunnels, caverns and other engineering operations. The general working pressure is less than 12 bar, and the higher bursting pressure can reach 36 bar. Sometimes the vacuum rich negative pressure parameter is 0.8 bar 0.9 bar. Suction pipe company Hydraulic requirements 1. The maximum working pressure of wear-resistant sand blasting hose is 0.63MPa. 2. The hose shall be free from water seepage, local bulge, expansion and other abnormalities when conducting hydraulic test under twice the working pressure. Keep the pressure of anti-static hose for 1min, and the length change shall not exceed ± 0.8%, the outer diameter change shall not exceed ± 10%, and the torsion per meter shall not exceed 60 º. 3. The bursting pressure of the hose shall not be less than 4 times of the working pressure.

1. Mutual wear of rubber lining plate and steel ball of ball mill: both the rubber lining plate and steel ball of ball mill are vulnerable parts. During grinding, the steel ball and material of ball mill do throw line falling movement in the barrel Xiamen Suction pipe It will collide with steel balls and materials and cause friction. In continuous operation, the rubber lining plate and steel ball of ball mill will be severely worn, which is directly related to the hardness of materials. The greater the hardness of the material, the faster the abrasion speed of the rubber lining plate and steel ball of the ball mill, which may cause equipment damage or even safety accidents in serious cases. In addition, it is also related to the ball of the ball mill. The size and quantity of the ball will affect the service life of the rubber lining plate of the ball mill. If the ball mill is in operation, increasing the amount of steel balls or filling steel balls with larger diameters will increase the wear of the rubber lining plate of the ball mill. 2. The heat treatment process of the rubber lining plate of the ball mill is unreasonable: the unreasonable heat treatment of the rubber lining plate of the ball mill will not only increase the wear of the lining plate, but also affect the yield strength of the lining plate, resulting in the fracture of the bolt of the ball mill under the large shear force. In the actual operation, the staff lacked the understanding of the lining plate material and the heat treatment processing of the ball mill rubber lining plate was insufficient, so the strengthening effect of the ball mill rubber lining plate was not in place and the strength was low. When impacted by steel balls and materials, Suction pipe company Plastic deformation often occurs. 3. The material of the rubber lining plate of the ball mill is unreasonable: the material of the rubber lining plate of the ball mill and its heat treatment process are the key to determine the mechanical performance of the lining plate. If the material of the lining plate is not properly selected, its fatigue strength and life will be greatly reduced, which will not meet the requirements of the ball mill, or even plastic deformation or bulge will occur.

If conditions permit, secondary vulcanization shall be adopted, wear-resisting Suction pipe 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, Xiamen Suction pipe 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.

Xiamen wear-resisting Suction pipe Plays an important role. 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, Suction pipe company 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.
