How to effectively detect the internal wear of Hydraulic Hose?

In the industrial field, the normal operation of the hydraulic system is essential for the efficient operation of the equipment. As an important part of the hydraulic system, the internal wear of Hydraulic Hose directly affects the safety and reliability of the system. Therefore, effectively detecting the internal wear of hydraulic hoses has become a key task.
First of all, visual inspection is a simple and effective preliminary detection method. Observe whether there are abnormal phenomena such as cracks, bubbling, deformation, etc. on the outer surface of the hydraulic hose. If obvious damage is found on the outer surface, there is a high probability that there is also a wear problem inside. In addition, check whether there are signs of leakage at the joints of the hose, which may also be caused by internal wear.
However, visual inspection can only find some obvious problems, and more professional methods are needed for the detection of internal wear. Pressure testing is a commonly used detection method. By applying a certain pressure to the hydraulic hose, observe whether it can withstand the specified pressure without leakage or rupture. If there is a problem during the pressure test, it is likely that the strength of the hose is reduced due to internal wear.
In addition, ultrasonic testing is also an effective detection method. Ultrasonic waves can penetrate the wall of the hydraulic hose and detect whether there are defects such as wear and cracks inside. This method has the advantages of non-destructiveness and high detection accuracy, and can accurately detect the location and degree of internal wear.
Another method is to use an endoscope for inspection. Inserting the endoscope into the hydraulic hose can directly observe the internal wear. This method is intuitive and accurate, but requires professional equipment and technicians to operate.
In order to effectively detect the internal wear of the hydraulic hose, regular maintenance and inspection are also required. Make a reasonable maintenance plan and replace the hydraulic hose regularly to avoid severe internal wear due to excessive use. At the same time, during use, pay attention to avoid excessive bending, stretching and squeezing of the hose to reduce the risk of internal wear.
