Maintenance and selection points of hydraulic hose

1. Maintenance
Regular inspection of the appearance of hydraulic hoses is an important part of maintenance. Check whether there are signs of wear, scratches, bulges, leakage, etc. on the surface of the hose. For damaged hoses, they should be replaced in time to avoid hydraulic system failure or even safety accidents. At the same time, pay attention to keeping the hose clean to avoid impurities such as oil and dust adhering to the surface of the hose, which affects its heat dissipation and service life. When the hydraulic system is repaired or the hydraulic oil is replaced, the hydraulic hose should also be inspected and maintained accordingly.
2. Selection points
When selecting a hydraulic hose, the first thing to consider is the working pressure of the system. It must be ensured that the rated pressure of the selected hose is higher than the maximum working pressure of the system and has a certain safety margin. The second is the flow requirement. According to the flow of the hydraulic system, a hose with a suitable inner diameter should be selected to ensure the smooth flow of the hydraulic oil and avoid excessive pressure loss. In addition, working environment factors such as temperature, humidity, chemical corrosiveness, etc. should also be considered. If working in a high temperature environment, it is necessary to select a hose material that is resistant to high temperature; in an environment with a risk of chemical corrosion, a hose with corresponding corrosion resistance should be selected. At the same time, the bending radius of the hose is also a factor that needs to be paid attention to when selecting. It is necessary to ensure that the bending radius of the hose during installation and use is not less than the specified minimum bending radius to prevent the hose from being damaged due to excessive bending.

In short, as a key component of the hydraulic system, the performance and quality of the hydraulic hose directly affect the reliability and safety of the entire system. A deep understanding of the structure, principle, application field, maintenance and selection points of the hydraulic hose is of great significance to ensure the normal operation of industrial equipment and improve production efficiency.
