I believe everyone is familiar with wear-resisting Sand suction hose Relevant application knowledge of products. It is understood that at present, this product is mainly used for mining hydraulic support and oilfield development. It is applicable to engineering construction, lifting transportation, metallurgical forging, mining equipment, ships, injection molding machinery, agricultural machinery, various machine tools, mechanization of various industrial departments, water-based liquids, etc. And liquid transmission. Its relatively high working pressure can reach 70-120 MPa. In order to achieve better application effect, what problems should be paid attention to when using high-pressure braided hose? 1. The bending radius shall not be less than the given bending radius to prevent damage to the hose skeleton or premature failure due to excessive tension. 2. Select the type and specification of the hose correctly according to the use conditions, and do not misuse or replace it. 3. When using high-pressure braided hose, the pressure should be adjusted slowly and evenly to avoid sudden pressure increase and damage to the pipe body. 4. When the work site changes, it should be removed from the ground without dragging, so as to avoid the skeleton layer being corroded after scratching the outer glue. 5. After delivering corrosive liquid, the interior should be cleaned to prevent residues from corroding the pipe body for a long time, or select corresponding series of products. When storing high-pressure braided rubber hoses, depending on the type of rubber used, Sand suction hose Price Note which conditions typically change over time. However, due to several factors or a combination of several factors, this change may accelerate, and other materials used to strengthen high-pressure braided hoses may also be adversely affected by improper storage conditions.

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. Xuzhou Sand suction hose 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. Sand suction hose 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.

Although fire Xuzhou Sand suction hose Explosion proof pipe) can be compressed and stretched, but if the installation position is incorrect, it will break quickly and reduce the service life. The sandblasting hose can be installed horizontally, vertically or obliquely. The most ideal condition is vertical installation. At the same time, avoid installing near the wheel, and install baffle if necessary. Generally speaking, the flame spraying metal sand blasting hose (explosion-proof pipe) can be divided into three lengths: the first is the compression length, that is, the length of the sand blasting hose when it is compressed to the limit position; The second is the installation length, that is, the length of the sandblasting hose when it is in the middle of half of the maximum displacement. The third type is the stretching length, that is, the length when the sandblasting hose is stretched to the maximum limit. When installing the sandblasting hose, the sandblasting hose should be in the middle position, which is called the installation length. When installed at this position, the sandblasting hose can move in two directions when bearing axial load. Otherwise, if it can only move in one direction, its strength will be affected and its service life will be reduced. In the actual installation process, considering that measuring the length of the sandblasting hose with a ruler according to the calculation results may affect the production efficiency, some foreign manufacturers directly install the ruler on the sandblasting hose, and cut the ruler after installation. From the structural point of view, the metal flame spraying metal sandblasting hose (explosion-proof pipe) is composed of strip and tube parts, which can form annular flame spraying metal sandblasting hose bellows and spiral flame spraying metal sandblasting hose bellows. Sand suction hose Price Just because the corrugated pipe of the fire sprinkler metal sandblasting hose formed by this article always has a certain length of brazing or welding buckles and fire sprinkler metal sandblasting hose joints, the residues of the working medium often accumulate in these places, and the cleaning test and mechanical impurities in the working medium will deposit down to pollute the inner cavity. Therefore, its use reliability is relatively poor.

wear-resisting Sand suction 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, Sand suction 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.

Xuzhou Sand suction 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. Sand suction hose Price The main control function of the air compressor station unit is to exhaust more air. According to different structures, it can be divided into full hose, cloth hose, steel braided hose, etc. According to different uses, it can be divided into air hose, water suction hose, water delivery hose, heat resistant hose, acid (alkali) resistant hose, oil resistant hose and special hose., It can be closed within the specified range.
