Hydraulic hose is also known as hydraulic oil pipe, hydraulic hose, high-pressure hose, hydraulic pipe, steel wire high-pressure pipe, steel wire braided hose, and steel wire winding hose. It is generally divided into steel wire braided hydraulic hose and steel wire winding hydraulic hose. The hydraulic hose is mainly composed of a liquid-resistant inner rubber layer, a middle rubber layer, 2 or 4 or 6 layers of steel wire winding reinforcement layer, and an outer rubber layer. The inner rubber layer has the function of making the conveying medium withstand pressure and protecting the steel wire from erosion. The outer rubber layer protects the steel wire from damage, and the steel wire layer is a skeleton material that plays a reinforcing role.
Equipment introduction
Medium temperature
Oil -40 degrees to 100 degrees; air -30 degrees to 50 degrees; water -0 degrees to 80 degrees.
Medium
Hydraulic power transmission or delivery of high-pressure media such as water, gas, and oil to ensure the circulation of liquid and transfer liquid energy.
Implementation standards
The standards commonly used in domestic and foreign trade of hydraulic hoses include DIN, SAE, ISO and GB/T standards;
The standards for wire braided hydraulic hoses are: DIN EN 853, SAE J517, GB/T 3683-2011, ISO1436;
The standards for wire wound hydraulic hoses are: DIN EN 856, SAE J517, GB/T 10544-2003, ISO3862.
