The outer surface of the hydraulic hoses is exposed to various working environments all the year round, so the outer rubber layer of the hydraulic hoses is the part that is most likely to be damaged by friction and erosion. The following are some common failures that easily occur in the outer rubber layer of the hydraulic rubber hoses, as well as its hazards and ways to avoid them.
The phenomenon of cracks on the outer surface of the hydraulic hose generally occurs in a cold environment. Generally, if a crack is found, the corresponding pipe needs to be replaced in time. Continuing to use the hydraulic rubber hoses after a crack occurs will cause the hoses to bend, which may cause further accidents. If the system pressure is too high, or if there is distortion during installation, it will also lead to the rupture of the hydraulic hose, and it will make the hydraulic hose unusable, so it must be replaced. In addition, with the passage of time, the outer rubber layer will inevitably age, and the aged rubber will become very brittle. Little pressure will cause cracks, so when you encounter cracks in the outer rubber layer of the hydraulic rubber hose, be sure to replace it in time
The reason for bubbling on the outer surface of the hydraulic hose is generally that the quality of the hose is not up to standard, or the hose does not match the working conditions, or it is used improperly during work. The causes of the bubbling can be determined by the location of the bubbling: if the bubbling on the outer rubber layer of the hydraulic hose appears at the position of the hydraulic hose joint, it is likely that the joint installation is unreasonable; if the bubbling appears in the middle part of the hydraulic rubber hose, It may be that the quality of the hydraulic hose selected and purchased does not meet the requirements.
This situation may be caused by the erosion of the inner rubber layer when the high-pressure oil-based liquid is transported, and the pipeline cannot work normally.
The above are several common failures that are prone to occur in the outer rubber layer of hydraulic hoses, involving the selection of hydraulic hoses, the crimping of hydraulic hose joints, and the precautions for installation and use.
