Introduction of hydraulic hose

Hydraulic hose is a type that is superior to ordinary rubber hose in terms of performance and function. It is mainly wound by inner rubber layer, middle rubber layer and several coils of steel wire. The inner rubber layer plays a role. It is to allow the conveyed medium to withstand a certain pressure and at the same time to prevent the steel wire from being corroded. The outer rubber layer is to prevent the steel wire from receiving other types of damage. The framework material plays a certain role in reinforcement. It can not only use hydraulic power to transport media such as water and air, but also transmit high-pressure media such as oil, so that it can ensure the continuous circulation of liquid and the transfer of energy.
As a kind of hydraulic transmission power pipe fittings, hydraulic hoses naturally have a set of standards that cannot be ignored. Let’s take a closer look at those national standards: The hydraulic hoses used in domestic and foreign trade are DIN, SAE, ISO and GB/T standards, which are standards for judging the quality of hoses, play a very important role in commodity transactions. And another kind of steel wire braided hydraulic hose standard is DIN EN 853, SAE J517, GB/T 3683-2011, ISO1436 these standards express the braid strength of hydraulic hose. Finally, there is a hydraulic hose standard for wire-wound type, that is DIN EN 856, SAE J517, GB/T 10544-2003, ISO3862. These standards are mainly used for commercial hydraulic hoses.Generally speaking, due to its excellent performance and special structure, hydraulic hoses can be used in oilfield mining and engineering construction, lifting and transportation, ships and agricultural machinery, etc., and it can also be used in various automatic hydraulic systems. Play a very important role.
