    Causes of hydraulic hose failure(1)

    Hydraulic hose failure is a serious problem, regardless of the industry or type of equipment involved. Hose failure can lead to downtime of the machine and the entire system, as well as costly maintenance costs and other financial losses. If high-pressure equipment is involved, employees may be at physical risk in the event of a failure.

    1. Hose Wear

    When the pressure inside the hydraulic hose changes, there will be shrinkage or stretching. When the hose is rubbed against the object (including other hoses, especially the metal edges), it may cause the outer adhesive layer to wear out. This is a very common cause of hydraulic hose failure and can cause hydraulic oil leaks when the outer adhesive layer of the hose is worn to the exposed rebar line.

    To reduce wear, a PP Spiral Guard or Nylon Fabric Hose Guard can be used to protect the hose.


    2. Hose distribution

    Another major cause of hydraulic hose failure is poor wiring. Avoid passing the hose through the abrasive area or pivot point. Do not pass the hose through the high temperature area unless there is no way. Pay close attention to the minimum bending radius of the hose to avoid bending, knotting and damage.

    If the hose may move, consider using a rotary connector at its end. In short, use spare lines, longer hoses or different accessories as needed to minimize wear and bend of hoses.
