胶管结构通常分为:内胶层、外胶层和骨架层(或称中间层)。内胶层直接承受输送介质的磨损、侵蚀;外胶层保护胶管内体不受外界环境的损伤和侵蚀;骨架层是胶管的承压层,赋予管体强度和刚度。胶管的工作压力取决于骨架层的材料和结构。
The structure of rubber hose is usually divided into inner layer, outer layer and skeleton layer (or intermediate layer). The inner rubber layer bears the abrasion and erosion of the conveying medium directly; the outer rubber layer protects the inner part of the rubber tube from the damage and erosion of the external environment; the skeleton layer is the pressure layer of the rubber tube, which gives the strength and stiffness of the tube body. The working pressure of rubber tube depends on the material and structure of the skeleton layer.
按骨架层不同,常见的胶管有:
According to the skeleton layer, the common rubber hoses are:
全胶胶管(无织物材料)
Full rubber hose (non-woven material)
夹布胶管(骨架层为布层)
Clamp hose (skeleton layer is cloth layer)
抽吸胶管(布层外还有一层金属螺旋线,适合负压条件下的作业)
Suction hose (there is also a layer of metal helix outside the cloth, suitable for operation under negative pressure)
编织胶管(骨架层为编织的钢丝或织物)
Braided hose (steel wire or fabric with braided skeleton)
缠绕胶管(骨架层为钢丝或线绳缠绕层,承受力常见在80~600MPa乃至更高的压力)
Winding hose (skeleton layer is steel wire or wire rope winding layer, withstanding force is common in 80 ~ 600 MPa or even higher pressure)
针织胶管(骨架层为针织物)
Knitted rubber hose (knitted fabric in skeleton layer)
短纤维胶管(短纤维与橡胶共混压而成)
Short fibre hose (made of short fibre and rubber by blending and pressing)
