What structure of hydraulic hose

What structure of hydraulic hoseFirst, the use of positive pressure (pressure hose)Structure: general use of cloth, weaving, winding or knitted structure
Design elements:1 Depending on the size, structure and work pressure, select suitable matrix materials, and calculating and determining the value of the compressive strength of the hose.(2) to ensure the required compressive strength under the premise of minimizing structural layers.3 tube structure seeks light, soft.Second, the use of negative pressure Hydraulic adapters (suction hose)Structure: usually spiral fabric layer and the metal structure as a support skeleton.Design elements:1 Depending on the size and use of elements of fire, and select suitable matrix material, and  Hydraulic hose fittings determine structural levels.(2) guarantee the achievement of suction vacuum requirements, does not suck deflated, no deformation.3 Bending better performance, lightweight, soft.Third, in the positive or negative pressure can be used under conditions (pressure, attract dual hose)Structure: usually cloth layer and the metal spiral for the support and bearing skeleton layer structure.Design elements:1 Depending on the size, pressure level and use requirements, calculations and select suitable matrix material and determine its structural level.(2) guarantee the achievement of suction vacuum requirements, does not suck deflated, no deformation.3. Ensure the required compressive strength.4 pipe body should maintain good bending performance.
