About Hydraulic hose

Hydraulic hose from the inner rubber layer, the reinforced layer and the outer rubber layer (Figure 7),

the inner rubber layer is in direct contact with the oil, so the requirements should not be fluid corrosion.

In the long-term working condition can leak in the enhancement layer. Under the action of can withstand

the pressure. Therefore, appropriate use of nitrile rubber, the rubber material, influence the main factors

and performance of the inner rubber layer thickness and hardness, permanent deformation. The great

influence of hardness and permanent deformation of the sealing performance. High hardness,

permanent deformation after compression, the sealing performance is better. In general is 70 ~ 85

hardness, compression permanent deformation of 50% is the best. The best thickness is 1.5 ~ 2.5mm,

too thick will increase its flow volume in buckling caused by excess glue, the joint core sleeve and hose

contact surface accumulation, reduce the circulation section; too thin will be withheld. At the same time

fracturing in inner layer The wall thickness uniformity is also very important. If the uneven thickness,

compression will cause a break, a pile of rubber. Important factors in the surface appear pit also affect

the quality of the performance.
