Hydraulic hose alias hydraulic oil hose, hydraulic 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. 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 layers, 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 the skeleton material for reinforcement.

   Responsible for transporting high-pressure liquid In the hydraulic system, the high-pressure rubber hose is used as a pipeline for liquid transportation, and is responsible for transporting the liquid from the hydraulic source to the actuator, such as hydraulic cylinder, hydraulic motor, etc.
    Withstand high pressure and pulsating pressure In the hydraulic system, the high pressure hose bears high pressure and needs to have better pressure resistance and strength. At the same time, pressure pulsation often occurs in the hydraulic system, and the high-pressure hose needs to withstand the pulsating pressure to ensure the normal operation of the system.
    Transmission of control signals In some hydraulic systems, high-pressure hoses not only play the role of conveying medium, but also need to transmit control signals. For example, in some hydraulic systems, high-pressure hoses are required to control the opening and closing of valves.
