The high-pressure hose structure has one layer of steel wire braided hose, two layers of steel wire braided hose, three layers of steel wire braided hose, four layers of steel wire wound hose, six layers of steel wire wound hose, general diameter hose diameter 6-102, large diameter hose diameter 102-300. There are high-pressure hose and low-pressure hose. Low-pressure hose has more sizes than high-pressure hose. Several types of high-pressure hose are also easy to remember. Professional focus on creating high quality high pressure tubing, with long service life, small bending radius, high pressure, fatigue resistance and other properties. High pressure hose ozone resistance, high and low pressure resistance, temperature resistance (-80 to 300 degrees), high transparency, strong resilience, resistance to compression permanent deformation, oil resistance, stamping resistance, acid and alkali resistance, wear resistance, flame resistance, voltage resistance, conductivity and other properties. The hydraulic hose mainly relies on the reinforcement layer to bear the pressure. Braided rubber hose is glued firmly to the inner and outer rubber layers by the glue slurry. Due to the mutual contact between the steel wires in the same braided layer, the durability of the steel wires will be affected by the friction between the steel wires due to their different expansion and contraction when subjected to dynamic pressure. The winding pipe is formed by two layers with different winding directions to form a working layer, and there is an intermediate glue between the two layers, so there is no intersection between the two layers of steel wires of the same working layer. Therefore, it will not form stress concentration or friction and wear when subjected to dynamic pressure with the cross bending between the steel wires. Therefore, it has good durability and can withstand high pressure.

High-pressure rubber hose is an important part of the hydraulic system of pipeline engineering machinery such as pipeline pressure opening, pipeline cutting, hydraulic mud pump, etc. Due to the harsh working environment in the use process, it is often exposed to the working environment of high temperature, high pressure, high pollution and high dust, which will lead to leakage, crack, rupture, loosening and other faults. However, under normal circumstances, just simply replace the hose without carefully analyzing the cause of the above failure of the hose, and the same failure will be repeated soon after the new use. High-pressure hose loose or rupture and other phenomena, resulting in the waste of hydraulic oil will pollute the environment, but also affect the work efficiency, and even

Hose (hose) assembly is a commonly used auxiliary device in hydraulic system. It is made of high-pressure steel wire braided or wound hose and steel joints buckled by special equipment. It is used to connect various hydraulic components in the hydraulic system. It is mainly used for hydraulic power transmission or delivery of high-pressure media such as water, gas, oil, etc. under the condition of working temperature of -40 ℃ to 100 ℃ to ensure the circulation of liquid and the transmission of liquid energy.

1. product structure: steel wire braided hose structure is composed of liquid-resistant synthetic rubber inner rubber layer, middle rubber layer, I or II or III steel wire braided reinforcement layer, and synthetic rubber outer rubber layer with excellent weather resistance. 2. product uses: Steel wire reinforced hydraulic rubber hoses are mainly used for mine hydraulic supports and oil field mining. They are suitable for engineering construction, lifting and transportation, metallurgical forging, mining equipment, ships, injection molding machinery, agricultural machinery, various machine tools and various industrial sectors. In mechanized and automated hydraulic systems, petroleum-based liquids (such as mineral oil, soluble oil, hydraulic oil, fuel oil, lubricating oil) and water-based liquids with certain pressure and temperature are transported

High-pressure hose is an important hydraulic system component of the hydraulic system of pipeline construction machinery such as pressure tapping machine, self-climbing hydraulic pipe cutting machine, hydraulic mud pump, etc. Leakage, crack, rupture, loosening and other faults often occur in use. Pressure tapping construction operators often simply replace the hose without analyzing the cause of the fault, and the same fault will be repeated soon after use, which is finally attributed to the quality problem of high-pressure hose. In fact, the loosening or rupture of the high-pressure hose not only wastes hydraulic oil, pollutes the environment, but also affects work efficiency, and even accidents occur, endangering the safety of man-machine. Hose pipes for pipeline engineering machinery are divided into high pressure hose and low pressure hose.

The difference between domestic and imported hose is mainly the product formula and manufacturing process. In such a large rubber industry, it is inevitable to avoid the mixed situation of good and bad people. What methods can we use to help users select good products for appearance inspection? We can see the methods that can be operated by hands. 1. Whether the internal glue is degummed or not, the degumming is caused by too many mixed and inferior glue. 2. Whether the inner adhesive layer is uniform or not is related to equipment modulation. A good product should be that the inner adhesive layer is tight and uniform. 3. Use your fingers to pinch the rubber layer. Good elasticity is better! 4, high brightness for the glue type 5, invisible method test, pressure test under the national standard requirements
