Introduction and description of hydraulic hose
Hydraulic hosealso named hydraulic oil hose, high pressure hose, hydraulic hose, steel wire high pressure hose, steel wire braided hose steel wire wound hose, generally divided into steel wire braided hydraulic hose and steel wire wound hydraulic hose. Hydraulic hose is mainly composed of liquid resistant inner rubber layer, middle rubber layer, 2 or 4 or 6 layers of steel wire winding reinforcement layer, outer rubber layer, the inner rubber layer has the effect of making the transmission medium under pressure, protecting the steel wire from erosion, the outer rubber layer protects the steel wire from damage, the steel wire layer is the skeleton material plays an enhanced role.
The role of hydraulic hose is to carry out hydraulic power transmission or transport water, gas, oil and other high pressure media, to ensure the circulation of liquid and transfer liquid energy.
Hydraulic hose domestic and foreign trade often used standards include DIN, SAE, ISO and GB/T standards;
Steel wire braided hydraulic hose standards :DIN EN 853, SAE J517, GB/T 3683-2011, ISO1436;
Steel wire wound hydraulic hose standards :DIN EN 856, SAE J517, GB/T 10544-2003, ISO3862.
Characteristics of hydraulic hose is:
1. The hose is made of special synthetic rubber with excellent oil resistance, heat resistance and aging resistance.
2. Tight tube body, soft to use, small deformation under pressure.
3. The hose has excellent bending resistance and fatigue resistance.
4. High pressure hose, superior pulse performance.
The use of hydraulic hose is:
Products are mainly used in mine hydraulic support, oil mining, 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, automation has certain pressure in hydraulic system (high pressure) and temperature of oil (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 transmission, the highest working pressure up to 60MPa.
