When using steel wire braided rubber hoses, a very practical question is often considered, which is how long the hydraulic hose can last, and this question is also related to the use of the hose. Proper installation of rubber hoses is crucial. If the hose is too long, it not only affects its appearance but also increases costs. If the hose is too short and there is not enough space to expand and contract when stretched or compressed under pressure, it may also be damaged. Most hose failures are caused by improper installation of hose assemblies on hydraulic systems, and in most cases, hose components will experience unacceptable torsional stress. In the current hydraulic system, the main symptoms of hydraulic hose pipeline faults are as follows:

1. The outer layer is torn or damaged, and there are signs of friction or corrosion on the reinforcement layer.

2. Break at the bend.

3. The inner adhesive layer is severely damaged, swollen or blistered, and may even peel off.

4. Outer layer foaming, inner or outer layer foaming or softening.

5. There are small cracks in the inner adhesive layer, but it still maintains elasticity, but no obvious cracks are seen at the joints.

6. At ambient temperature, steel wire braided rubber hoses become hard, brittle, and burst; There are signs of dryness or scaling on the outer adhesive layer.

7. At the operating temperature, the inner or outer adhesive layer cracks, but still maintains softness and elasticity.

8. Bursting can shorten the service life, usually occurring suddenly, with no signs of wear on the steel wire and outer rubber layer.

9. The rubber hose is leaking and the inner pipe is punctured.

10. The rubber hose broke at the jacket joint.

The above lists some common faults of steel wire braided rubber hoses in general hydraulic systems, which directly affect the use of hydraulic rubber hoses. In most cases, if the above phenomenon occurs, replacement is necessary, otherwise it will pose a serious threat to the safety and reliability of the entire hydraulic system.
