Hydraulic hose alias hydraulic tubing, hydraulic hose, high pressure hose, hydraulic pipe, steel wire high pressure pipe, steel wire braided hose steel wire winding hose, generally divided into steel wire braided hydraulic hose and steel wire winding hydraulic hose Hydraulic hose according to the material of rubber material and rubber and plastic material two categories. According to the production process, it is divided into steel wire braided hose, steel wire winding hose, wire braided hose and cloth clip hose 1. Hydraulic hose structure: mainly composed of liquid resistant synthetic rubber inner layer, middle layer, multi-layer reinforcing layer and weather resistant synthetic rubber outer layer. The inner rubber layer has the function of making the conveying medium withstand pressure and protecting the steel wire or wire fiber from erosion. The outer rubber layer protects the reinforcement layer from damage. The reinforcement layer is the skeleton material, and its function is to ensure the use pressure of the hose. 2. hydraulic hose use: Mainly used for mine hydraulic support, oil field development, Suitable for engineering construction, lifting, transportation, metallurgy forging press, mining equipment, vessels, injection molding machinery, agricultural machinery, all kinds of machine tools and various industrial departments mechanization and automation of hydraulic system with certain pressure and temperature of oil in the base (such as mineral oils, soluble oil, hydraulic oil, fuel oil, lubricating oil) and water-based liquids (such as emulsion, oil-water emulsion, water) and liquid Move. Rubber and plastic material of hydraulic hose, also known as rubber and plastic hose, is a new type of hose, its corrosion resistance and energy saving effect is obvious. 3. hydraulic hose working temperature: -40℃ ~ 120℃ four, product specifications range: DN2.5mm ~ DN305mm.

Because of the complex variety of hydraulic hose, the structure is diverse, and the use of different conditions, so the length of the service life of the hose, not only depends on the quality, but also depends on the correct use and maintenance. So even if the product has very high quality, if not correctly used and maintained, it will seriously affect its use quality and life, and even cause undue serious accidents, causing losses to property. The following points are provided for attention: 1, hose and hose assembly can only be used for conveying designed materials, otherwise it will reduce the service life or failure. 2, the correct use of hose length, hose in high pressure length change (-4%-+2%) and mechanical movement caused by the length change. 3. The hose and hose assembly shall not be used under pressure (including impact pressure) exceeding the design working pressure. 4. Under normal circumstances, the medium temperature transported by the hose and hose assembly should not exceed -40℃-+120℃, otherwise the service life will be reduced. 5. the hose and hose assembly should not be less than the minimum bending radius of the hose, avoid bending or bending near the pipe joints, otherwise it will hinder the hydraulic transfer and conveying materials or damage the hose assembly. 6 . hose and hose assembly, should not be used in the state of torsion. 7 . the hose and hose assembly should be carefully handled, should not be dragged on the sharp and rough surface, should not be bent and compressed. 8. hose and hose assembly should be kept clean, the internal should be washed clean (especially acid pipe, spray pipe, mortar pipe). Prevent foreign objects from entering the cavity, blocking the conveying fluid and damaging the equipment. 9. over the service period or storage period of the hose and hose assembly to be tested and identified before continuing to use.

1. Gas drainage hole sealing device Purpose: coal body water injection, gas drainage gas. Ii. Functions: 1. Water enters the coal body, releases some gas, and effectively reduces the gas content in the coal body. 2. After water injection achieves the effect, dust can be reduced by more than 80%, workers' working environment can be improved, and dust explosion accidents can be prevented. 3, wet coal, reduce pyrotechnics products, reduce costs, increase workers' sense of security; 4. Play an anti-outburst effect, effectively release the in-situ stress and gas pressure, eliminate the occurrence of coal cutting outburst accident; 5. It solves the problem of gas exceeding limit when cutting coal mine and preventing sudden drilling, and can effectively prevent coal and gas outburst and explosion. Iii. Structure: The sealing device is composed of high pressure rubber expansion hose, intermediate steel pipe, sliding sealing joint and injection pressure joint. Four, note: The feeding and sealing hole and the recycling and sealing hole are strictly prohibited to operate with pressure.

Coal seam water injection sealing device is composed of high pressure rubber expansion hose, safety valve and quick joint. Coal seam water injection hole sealing device is mainly applicable to media or rock mass in grouting, water injection and after the plugging hole. Matters needing attention 1. The use of coal seam water seal hole fast and simple. It is only necessary to connect the water path of the operation site with the packer, and insert the packer into the borehole completely. Under a certain pressure, the packer hose expands to seal the hole and break the coal by water injection. The sealing device of coal seam water injection can be used repeatedly for several times. When the pressure is removed at the end of water injection, the sealing device can return to its original state and be taken out. It is strictly prohibited to operate the feeding and recovery packer with pressure. No one is allowed to work in front of the hole packer when it is working. The hole sealer must be used straight, no discount pressure. When in use, adjust the sequence valve (the opening pressure should be greater than), the pipeline should be monitored by a pressure gauge, the pressure water is strictly forbidden to be higher than the working pressure, the pressure water pipe is removed after the operation, and the hole sealing device is restored to its original state after the pressure relief and no water, and then the hole sealing device is extracted and sorted out for backup. 2.
