The hard core method adopts the core extrusion process to extrude the inner rubber tube blank, which directly uses the extruder to cover the inner rubber tube blank on the iron core, instead of the traditional casing process, and simplifies the process flow. Shangrao Oxygen tube The billet forming adopts the process method of intertwining outer film and steel wire braiding forming. Similar to wrapping water wrapped cloth, the overlapping width is 1/2 of the film width. This process method can replace the method of wrapping outer film by extruder or by hand, reducing energy consumption and cost. We all know that the reinforcing layer and reinforcing layer of the rubber hose are the main force bearing parts, which are used to bear the load pressure. The factors determining the stress condition of the reinforced layer of the rubber hose are determined by the tension of the braided steel wire and the braiding angle. The high-speed steel wire hose braiding machine developed by our factory has introduced the advanced technology of foreign braiding production lines, and integrated the characteristics of domestic braiding machines. It integrates the advanced functions of hydraulic brake hose braiding production line, such as horizontal mechanical transmission, automatic lubrication, and so on, to develop equipment with high productivity and high degree of automation. The range of braiding diameter can be achieved Ф 6— Ф 25 Long core rubber hose (reinforcement layer). It fills the gap of domestic knitting production equipment, which can be widely used in rubber and plastic hose, rubber hose (reinforcement layer) knitting production equipment. The structure of high-pressure rubber hose is composed of four parts: inner liner, inner rubber layer, skeleton layer, middle rubber layer and outer rubber layer. Oxygen tube Price In case of direct contact with the conveying medium, the synthetic rubber with good medium resistance, high tensile strength, high constant tensile stress, small compression permanent deformation and easy processing is usually selected. In order to meet the use requirements of strong polar medium resistance, the inner liner is composed of polytetrafluoroethylene layer and rubber layer, and a layer of film or adhesive is added on the surface of the inner liner to improve the adhesion with the skeleton material.

Shangrao high quality Oxygen tube 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, Oxygen tube 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.

Shangrao Oxygen tube 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. Oxygen tube Price 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.

Shangrao Oxygen tube It is widely used in mining, chemical industry, construction and iron and steel fields. At present, 90% of ball mills, rod mills and moistening mills on the market still use manganese steel cylinder liners, and the manganese steel material consumed on liners alone every year is more than one million tons. The emergence of rubber liners is favored by many big customers in the ball mill field. What are the indexes that affect the rubber lining plate of the ball mill? 1. Conditions of ball mill use scenario The feeding particle size of ore also plays an important role, so a good ball mill rubber lining plate will be designed according to the size of the customer's mill, feeding particle size, and steel ball diameter. Select the rubber formula suitable for customers, and carry out mapping, design, testing and processing. 2. Rubber formula and processing technology: The rubber material and formula directly affect the performance of the rubber lining plate of the ball mill. Wear resistance is a key factor. It is impossible to determine how long its service life is because of the impact of industrial and mining conditions. The second is corrosion resistance. This is the characteristic of the formula, so even if the appearance is the same, the performance is an advantage. Do not buy for cheap. 3. Regular maintenance: everyone knows that the rubber lining plate of the ball mill is fixed to the cylinder by means of T-bolts, so it is also very important to regularly check the tightness of the bolts and the wear of the rubber strips inside the cylinder. In order to avoid damaging the rubber lining plate of the cylinder and the cylinder of the ball mill when the lifting strip is worn out, the gain is not worth the loss. Oxygen tube Price One of the advantages of the manganese steel lining plate is that the replacement is simple and only needs two people to operate, and it can be replaced wherever it is broken. This is an advantage that the manganese steel lining plate does not have.

I, high quality Oxygen tube Quantitative display of quality. In the evaluation plan prepared by the Ministry of Health and Social Insurance for the medical and health system, some indicators were put forward for the service quality of the hospital, such as the number of deaths before and after the operation, the number of unplanned rehospitalization, the infection rate of patients in the hospital, and the immunization rate. It can be seen that the quantification of quality is to reflect the quality of things through a series of quantitative analysis and synthesis. Sand blasting hose enterprises use public opinion polls to measure benefits and service quality. Since the purpose of administrative activities is to meet the needs of society or the public, the best way to measure the social effect and quality is to face the service objects, understand their evaluation and their satisfaction. Although popular, public opinion polls also have limitations, such as high cost, which is difficult to be accurate and reliable due to the influence of public judgment. In addition, the satisfaction of beneficiaries does not answer the question - is this service provided to those who need it most? III, Oxygen tube Price Administrative departments and public service institutions with single business nature. For those departments that have applied the quality assurance system, their performance evaluation only pays attention to efficiency and economy.
