Hydraulic steel wire braided rubber hose execution standards and structure
Time:2023-12-04Page views:1584Hydraulic hoses are divided into two categories based on their materials: rubber and rubber plastic. They are also divided into steel wire braided hoses, steel wire wrapped hoses, and cloth wrapped hoses based on their production processes. The standards for steel wire braided hydraulic hoses include DINEN853, SAEJ517, GB/T3683-2011, ISO14369; The standards for steel wire wrapped hydraulic hoses include DINEN856, SAEJ517, GB/T10544-2003, and ISO3862.
1. Hydraulic hose structure: mainly composed of a liquid resistant synthetic rubber inner layer, a middle layer, multiple reinforcement layers, and a weather resistant synthetic rubber outer layer. The inner layer has the function of withstanding pressure on the conveying medium and protecting the steel wire or steel wire fiber from erosion. The outer rubber layer can protect the reinforcement layer from damage. The reinforcement layer is a skeleton material, which ensures the use pressure of the steel wire braided hose.
2. Application of hydraulic hoses: mainly used for mining hydraulic supports and oilfield development, suitable for engineering construction, lifting and transportation, metallurgical forging, mining equipment, ships, injection molding machinery, agricultural machinery, various machine tools, and mechanized and automated hydraulic systems in various industrial sectors. Used for transporting petroleum based and water-based liquids with corresponding pressure and temperature. Hydraulic hoses made of rubber materials, also known as rubber hoses, are a new type of hose with significant corrosion resistance and energy-saving effects.
3. Hydraulic hose working temperature: -40 ℃ -120 ℃ Hydraulic hose product specifications: DN2.5mm-DN305mm.
The steel wire braided rubber hose is made of special synthetic rubber, which has excellent oil resistance, heat resistance, and aging resistance. The pipe body is tightly combined, soft to use, with minimal deformation under compression, and has high resistance to bending and fatigue.
